NASH HERNANDEZ GREEN BUILDING FEASIBILITY ANALYSIS FOR SOLAR PHOTOVOLTAIC SYSTEM NATURAL GAS AVOIDANCE AUXILIARY WATER SUPPLY ELECTRICAL VEHICLE CHARGING STATION OCTOBER 29, 2025 PREPARED BY: ACR Engineering, Inc. 3001 South Lamar, Ste. 210 Austin, Texas 78704 (512) 440-8333 OVERVIEW In accordance with the project scope and the city of Austin policy, ACR has conducted an evaluation of “Green Building” features for consideration in the renovation of the Nash Hernandez Facility. The renovation of municipal facilities, such as Nash Hernandez, require a Green Building Feasibility Analyses as outlined in a City of Austin Memorandum dated June 12, 2020, and further detailed in the accompanying FINAL City of Austin Green Building Policy Update. See appendix A. The proposed final policy includes requirements for mandatory feasibility analyses for: 1. Rooftop solar installation. 2. Avoidance of natural gas. 3. Use of auxiliary water supply. 4. Provision of EV charging stations. This report presents the results of a high-level evaluation of these potential Green Building features for Nash Hernandez facility. These analyses are intended as a guide for the Owner to consider and determine which features to include, if any, in the plans for the current project and/or future development. 1 SOLAR PHOTOVOLTAIC SYSTEM A preliminary study was conducted to evaluate the Solar-Ready Zone Area within the mandatory “Reserved for Future Solar Installation” at the Nash Hernandez facility. The analysis utilized 3D roof views in conjunction with the 2D roof plan (see figure below). The Solar-Ready Zone is defined as 50% of the Potential Solar Area, identified as the red-shaded region. The Potential Solar Area is defined as free from obstructions such as, but not limited to, vents, pipes, ducts, and other equipment and must comply with access, pathway, smoke ventilation, spacing, and other requirements of the city of Austin Land Development Code. The red outline of the roof shall be reserved for future solar installation. Code Compliance Data (per C402.8 & C402.8.1): • Total Potential Solar Area: 5,796 sq ft • Total Solar-Ready Zone Area: 2,955 sq ft 2 Code Compliance Data (per C405.15.1): • Total Conditioned Space: 9,160 sq ft • Required Onsite Generation: 0.75 W/sq ft • Total Generation Required: 6,870 W • Generation per Panel: 340 W • Estimated Number of Panels: ~20 panels Electrical Provisions The electrical design for the Nash Hernandez project includes provisions for both future and solar photovoltaic (PV) installation to meet code requirements. A minimum generation capacity of 6.87 kW shall be provided, requiring the installation of 20 solar panels within the designated Solar-Ready Zone area. To support this installation, the following infrastructure will be included in a dedicated solar electrical distribution panel: • One (1) 30A, 3-pole breaker dedicated to the minimum 6.87 kW solar capacity. • One (1) 50A, 3-pole breaker allocated for the remaining load capacity of the Solar- Ready Zone area. The solar distribution panel will be sized based on the total Potential Solar Area to ensure that future PV system expansions can be accommodated without major construction. Structural Considerations The facility roof must be capable of supporting an additional load of approximately 8 lbs./sq ft. Additional structural reinforcements may be required to support anchoring of the system. Next Steps Design will include the following: 1. Performance specification for the installation of the code-mandated 6.87 kW of solar PV at the time of construction *. 2. Solar-ready infrastructure for future installation of solar PV utilizing the totality of the solar-ready area. * Alternatively, the Owner/ACR may elect to retain the services of a solar system designer and prepare a full design so it may be bid at the time of procurement. 3 NATURAL GAS AVOIDANCE IECC 2024 Considerations With the adoption of the 2024 International Energy Conservation Code (and associated City of Austin amendments), buildings must be constructed with provisions for (future) all-electric space heating and domestic hot water service, as well as kitchen appliances. The message from the City of Austin is clear but given the potential for additional first cost and operational cost associated with all-electric systems, we have prepared a brief evaluation for consideration by the Owner. Kitchen Equipment The design will include an electric cooktop and oven at the community kitchen. No gas-using kitchen equipment is envisioned nor desired. Domestic Hot Water Service. Uses for domestic hot water are limited to showers and lavatories. There is an existing natural gas service to the building, and in order to assist the Owner with a decision on whether to use gas-fired or electric domestic water heaters, ACR conducted an evaluation of the following three system types: • Storage tank gas-fired water heaters • Tankless/On-demand gas-fired water heaters • Electric heat pump water heater A brief summary of the major advantages and disadvantages of the various systems is presented below, followed by a comparison of first cost and operational cost. See appendix B for product data of the three water heater options. Storage Tank Gas-Fired Storage tank gas-fired heaters have been the “default” solution for domestic hot water production for many years. Modern storage type commercial gas water heaters have come a long way from the older generations which would last 5 years or less, and offer the following features: • Efficiency of up to 96% with condensing operation. • Low Nitrogen Oxide (NOx) emissions, compliant with SCAQMD Rule 1146.2 4 Internal heat exchanger designs that minimize scale formation. • • Power direct vent design that allows for combustion air and venting to pipe to the outdoors utilizing PVC piping, and eliminating the need for large openings to the outdoors. Internal gas coating for corrosion protection. • • Anode rods with stainless steel core for increased durability. • Most plumbers are familiar with installation and maintenance requirements. • The storage tank provides a buffer such that hot water is always available at a consistent temperature. Some of the disadvantages of gas-fired storage-type water heaters include: • Standby losses when sitting idle. • Space requirements for installation. • Does not address the Owner’s objectives for natural gas avoidance. Tankless/On-demand Gas-Fired In most other parts of the world (outside of the U.S.) gas-fired, instantaneous/tankless/on demand water heaters have been in common use for residential applications for many decades. In the U.S. they have only started gaining wider acceptance - primarily for high-end residential applications, in the last 15 years or so. Major advantages of tankless water heaters include: • Minimal standby losses. • High Uniform Energy Factor. • Reduced space requirements for installation, may be installed close to area served. • • Direct venting and combustion intake for indoor units. Indoor or outdoor use. Some of the disadvantages of gas-fired on-demand water heaters include: Heat exchangers are subject to calcium build-up in areas with hard water. Water softeners are typically recommended. • Hot water supply can sometimes be inconsistent, for example if the heater is sized for showers, but only a faucet is being used. • Does not address the Owner’s objectives for natural gas avoidance. Electric Heat Pump Heat pump water heaters represent the most efficient electric solution for hot water production, but their application can be limited due to a number of factors. The basic theory behind these 5 systems is that they can intake warm air, transfer the heat to the domestic water being heated via a heat pump compressor, and output cold air to the space. The new Austin amendments require provisions for future heat pump water heaters if the water heaters are above 75MBH, which would make this a more attractive option. However, current estimates show a total load of 20MBH, so no provisions are required if they are not in the client’s interest. Major advantages of heat pump water heaters include: • Meets Green Building objectives to avoid the use of natural gas. • High efficiency (coefficient of performance greater than 4). • Will work optimally during the summer months with warmer outdoor air as the heat source. • The storage tank provides a buffer such that hot water is always available at a consistent temperature. • Storage tank reduces reliance on auxiliary electric heat. Some of the disadvantages of heat pump water heaters include: • Heat pump water heaters have a somewhat lower recovery rate, and in order to avoid (excessive) use of auxiliary electric heat, larger or multiple units need to be provided to meet the load that a single gas-fired heater can meet. • Electrical service and distribution system has to be increased in order to support the load both in heat pump and straight electric heat operation. • Maintenance of heat pumps requires expertise that Owner’s plumbing departments typically don’t have in-house. • Units require significant space for operation and maintenance (3,200 cubic feet). First Cost and Operational Cost Comparison ACR requested pricing from a local representative, and in order to avoid bias, used the same manufacturer for all three water heater equipment alternatives. ACR also evaluated the potential operational cost associated with each alternative based on the manufacturer’s published data and the anticipated hot water usage/cost based on Owner’s anticipated use of the facility. The results are summarized below. 6 Type First Cost Life Exp. (yrs.) Warranty (yrs.) Annual Energy Cost Maintenance and Other Considerations Tank Type Gas WH $8,650 10-15 4 $1,445 Instantaneous Gas WH $2,500 20 Electric Heat Pump WH $9,636 10-15 6 4 $1,369 $1,104 ▪ Periodic Tank Flushing Required. ▪ Periodic Checks of Burner ▪ Periodic Checks of Venting System ▪ Anode Rod Replacement ▪ Ventilation Flues Required ▪ Maintenance Staff Familiar ▪ Cold Water Inlet Filter Cleaning ▪ Periodic Checks of Burner ▪ Periodic Checks of Venting System ▪ Ventilation Flues Required ▪ Periodic Tank Flushing Required ▪ Anode Rod Replacement ▪ Heating Element Limescale Removal ▪ 3,200 C.F. of Open Airflow Required We propose that given first cost considerations, space requirements and simplicity of operation, the use of instantaneous gas-fired water heaters be considered for this project, with the inclusion of electrical infrastructure to convert to electric in the future if desired/required. Should the Owner prefer to use any of the storage-type solutions (gas or heat pump), the currently envisioned space layouts will need to be modified in order accommodate the tanks. The heat pump solution evaluated would actually require two units installed in a dedicated space each in order to meet recovery rates, and provisions would need to be made to discharge cold air to the adjacent areas. HVAC Heating The 2024 IECC requirement to provide electrical infrastructure for future replacement of combustion heating equipment makes the consideration of gas-fired heating solutions a non- starter. Considering a gas-fired solution now, while providing capacity for a future all-electrical solution would result in excessive cost. Regardless of the considerations above, it has always been the intent of this design team to recommend an all-electric solution for HVAC. The following system is being considered: Inverter-driven air-cooled heat pump chiller. • • Fan-coil units with chilled water coils and electric heat. • Dedicated outside air unit with hot water preheat (from heat pump chiller) and chilled water coils. 7 AUXILIARY WATER SUPPLY The potential uses for an auxiliary water source are landscape irrigation, and for flushing the new water closets to be provided as part of the renovation. An evaluation conducted by ACR indicates that based on the projected facility operation during the months of June, July, and August, we could expect a total combined consumption of 10,800 gallons of water for toilet flushing. All of this consumption could potentially be provided from an auxiliary (non-potable) water source. We investigated two potential sources for this non-potable water source: • City’s “purple pipe” network • Rainwater Brief conceptual descriptions of each of these alternative water sources follow below: Purple Pipe 8 A review of the Austin Water Utility’s “purple pipe” network map shows that there are no pipes running in proximity to the Nash Hernandez building therefore is not an option at this facility. Rainwater Using average rainfall figures for Austin, and the facility roof area available for capture, ACR conducted calculations to determine the volume of rainwater that could potentially be collected each month: Month January: February: March: April: May: June: July: August: September: October: November: December: Projected Rainwater Collection (Gallons) 16,000 12,000 18,000 15,000 31,000 23,000 12,000 17,000 21,000 24,000 18,000 17,000 Rainwater for WC Flushing Conceptually, a 10,000-gallon tank could store enough water to meet the water-flushing requirements of the facility for a three-month period, with enough buffer to cover extended periods with little or no rain. The various technical and regulatory requirements for use of non-potable water from a storage tank within the facility are not trivial and can be costly, but it has been done in many other facilities. Some of the key considerations: • Size and location of tank(s) to allow for gravity drain from the roof. • Make-up water connection to the tank, such that it will not run dry. • Pump and compression tank to ensure adequate pressure for flush-valves at water closets -gravity-fed tank type water closets are not desirable. Rainwater for Irrigation A smaller (5,000 gallon) rainwater collection tank could be provided to meet site irrigation needs, including a potential community garden that could be located at the south end of the facility. The system would be entirely gravity-driven, with no pumps required, easing some of the cost and maintenance concerns associated with a pressurized system. Irrigation piping connecting to the tank would utilize purple pipe to indicate a non-potable source. 9 Condensate Collection The water collection tank could be set up to also capture condensate from the HVAC outside air unit, but special attention is required because: (a) condensate can cause metals to corrode; and (b) condensate cannot be used for irrigation of gardens for edible food production. The cost of a 10,000-gallon tank alone is expected to be in the $15,000 range, which excludes piping, pumps, structural supports or any other design elements. Should the Owner determine that a rainwater collection system as conceptualized here is worth pursuing, it could be incorporated into the design now, or provisions could be made so that it may be implemented at a later time. 10 ELECTRIC VEHICLE CHARGING STATIONS The installation of electric vehicle (EV) charging stations has become a standard requirement for commercial developments. In accordance with Code Section CG101.2.1, the Nash Hernandez facility (Group B – Business) is required to provide 30% of parking spaces as EV-Capable. An EV-Capable space is defined as a parking space with the necessary electrical infrastructure (e.g., raceways and panel capacity) to allow for the future installation of an EV charger without major construction. The facility provides a total of 20 parking spaces, requiring 6 EV-Capable spaces. A minimum electrical load allocation of 36.0 kW shall be reserved to support EV charging. Electrical Provisions The electrical design will include dedicated infrastructure to support the required EV-Capable spaces. Specifically, a dedicated EV distribution panel will be provided with three (3) minimum 50A, 208/240V circuit breakers to accommodate the required EV charging capacity. Charging Equipment At the Owner’s request, one Level 2 charging station will be installed near the facility entrance to serve two adjacent parking spaces. This charging station will utilize one of the three 50A breakers referenced above. See Appendix C for the basis-of-design 50A (Charge Point) charging equipment. 11 APPENDIX A CITY OF AUSTIN MEMORANDUM 12 RESOLUTION NO. 20210902-042 WHEREAS, in June of 2019, Council approved Resolution No. 20190619- 091, which required robust labor protections and sustainability requirements for third party development agreements that occur on city-owned land; and WHEREAS, in addition, the Resolution directed the City Manager to determine how the City could implement the goal of requiring all developments on city-owned land to create zero waste, net zero energy, and net positive water buildings and to recommend updates to the existing Green Building policy (Resolution Number 20071129-045) to further consider appropriate thresholds and policy revisions for public-private partnership projects (P3s's), minor renovations, and leased spaces; and WHEREAS, since the resolution's passage, a cross-departmental team including representatives from the Public Works Department, Office of Sustainability, Real Estate Services, Capital Contracting Office, Purchasing Office, Economic Development Department, Austin Energy Green Building, Small and Minority Business Resources, Aviation, Building Services, Parks and Recreation Department, Austin Convention Center, Austin Public Library, and the internal Strategic Facilities Governance Team have worked to craft recommendations; and WHEREAS, staff responded to Resolution No. 20190619-091 with a June 12,2020, staff memo recommending multiple policy changes to bolster the City's existing green building policies; and WHEREAS, the proposed changes outline a set of key policy priorities related to site selection guidance, net-zero and low carbon guidance, health and Page 1 of 3 wellness guidance through the WELL building standards, and sustainable landscape guidance; and WHEREAS, the memo further recommends updated performance standards for new construction for capital improvement projects, major and minor renovations and interior finish-outs for capital improvement projects, third-party financed and alternative delivery projects (such as public-private partnerships), and proposed new requirements for leased spaces; and WHEREAS, the memo also recommends proposed requirements for new construction capital improvement projects, major and minor renovations and interior finish-outs for capital improvement projects, and third-party financed and alternative delivery projects (such as public-private partnerships); these proposed requirements include mandatory feasibility analyses for rooftop solar installation, avoidance of natural gas, use of auxiliary water, provision of EV charging stations, and mandatory water balance calculations; and WHEREAS, staff recommended that further policy discussion take place regarding WELL and other building standards; updates to existing facilities; and requirements for public art; and WHEREAS, the June 12, 2020, staff memo details these recommended changes and considerations; and WHEREAS, staff has continued refining proposed changes to the Green Building Policy and provided Council with updated recommendations in the summary matrix and detailed policy language dated May 25,2021 ("Exhibit A") and Page 2 of 3 WHEREAS, the City of Austin affirms its commitment to reducing its carbon footprint, reducing water use, and fostering a community well-poised to address climate change and mitigate environmental pollution; NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF AUSTIN: 1.

In addition, a request was made to determine how the City could implement the goal of requiring all developments on City-owned land to create zero waste, net zero energy, and net positive water buildings. Purpose The purpose of the attached policy recommendation is to respond to Council direction, bring previous policies up to date with the current marketplace, and to reinforce the City of Austin's commitment to green building and sustainability. The proposed policy is intended to update and/or reinforce previous green building policies as referenced in Council Resolution Numbers: 000608-43, 20071129-044, 20071129-046, 20071129-04 and 20190619-091. Updates are needed to reflect Council priorities, changes in the marketplace, maturing of the green building industry, and additional policy directives adopted since the initial 2007 Council-mandated green building policy was adopted. This policy is intended to ensure that all development and building projects that the City is involved in are designed to standards of excellence. (See attached proposed policy language and recommendations.) is to ensure that the City of Austin's facility portfolio is leading the way in conserving The overall goal energy, water and other natural resources, promoting human health, safety and wellness, and ensuring a high-quality built environment. The City's commitment to-date is demonstrated by our significant portfolio of LEED certified or Austin Energy Green Building rated projects. Additionally, City Council's Strategic Direction 2023 provides a new outlook and set of priorities for the City. This policy relates to several indicators outlined in that guiding document, including: City of Austin (government activity) Carbon Footprint (HE. E.3) 1 Per Capita Water Use (HE.D.6) Energy Star scores of City buildings (GTW.B.4) Collaborative Team A cross-departmental team has contributed to preparing this response, including representatives from the Public Works Department, Office of Sustainability, Real Estate Services, Capital Contracting Office, Purchasing Office, Economic Development Department, Austin Energy Green Building, Small and Minority Business Resources, Aviation, Building Services, Parks and Recreation Department, Austin Convention Center, and Austin Public Library. In addition, the internal Strategic Facilities Governance Team provided review and feedback to these proposed policy revisions. Scope of Proposed Policy The City of Austin has existing City Council-adopted policy standards in place for City CIP and public-private partnership projects, also known as P3s. The proposed policy language attached updates and/or reinforces these existing policies. In addition, new policy guidance which did not exist previously is proposed for City leased spaces and tenants in City-owned buildings. Finally, new Key Policy Priorities are proposed for the City to address zero energy, water, and waste facilities per Council request. In addition, health and wellness strategies and sustainable sites and landscapes are addressed. Summary of Proposed Changes Outline of Key Policy Priorities (NEW) Site Selection Guidance: Choosing the right site can have a significant impact on the overall enjoyment and accessibility of a building as well as the carbon footprint of its users and occupants. The policy highlights the need for project locations that minimize transportation impacts and located in Imagine Austin Activity Centers and Corridors. Net-Zero and Low Carbon Guidance: The City of Austin has the goal to achieve net-zero community wide greenhouse gas (GHG) emissions by 2050. Meeting this target will require change in how we generate and use energy and how we move people around town. The policy outlines net-zero and low carbon strategies that should be encouraged and prioritized into all applicable projects. This includes several instances where feasibility analysis will be required for features such as rooftop solar, auxiliary water, or electric vehicle charging stations. . Health and Wellness Guidance: The environment In which a person spends their time can have a significant impact on their physical and mental health, as well as their productivity. Acknowledging that a majority of people's time is now spent indoors, "healthy buildings" seek to create indoor spaces that promote the overall health and wellbeing of occupants. Benefits include improved mood, satisfaction and productivity for building users with decreased absenteeism and healthcare costs. The policy outlines health and wellness strategies that should be encouraged and prioritized into all applicable projects. The policy encourages the use of the WELL building standard, which is currently being used in conjunction with the Development Services Center and Austin Energy Headquarters (See outstanding issues at end of memo). • Sustainable Landscape Guidance: The proposed policy for new construction for CIP projects includes a NEW requirement for PARD projects over $2M to achieve Sustainable SITES Certified. 2 Sustainability does not stop at the front doors. Sustainable landscapes provide numerous benefits for the environment, property owners, and communities. Thoughtfully designed landscapes can positively impact building and landscape performance, maintenance, and aesthetics as well as promote human and ecological health. The policy outlines landscape and green infrastructure strategies that should be encouraged and prioritized into all applicable projects. Performance Standards (UPDATED) • New Construction for Capital Improvement Projects: No Policy Threshold or Performance Standard changes for buildings proposed. NEW requirement for mandatory analysis of feasibility for rooftop solar installation, use of non-potable water, avoidance of natural gas use, and EV charging. • Major Renovations & Interior Finish-outs for Capital Improvement Projects: The Policy Threshold is proposed to be increased from $300,000 to $750K. NEW requirement for analysis of feasibility for rooftop solar installation, use of non-potable water, avoidance of natural gas use, and EV charging, as applicable to the scope. NEW mandatory analysis of feasibility for avoidance of natural gas use in renovations involving HVAC and/or hot water systems replacement and for rooftop solar installation in renovations involving roof replacements. • Minor Renovations & Interior Finish-outs for Capital Improvement Projects: The project should meet the LEED or AEGB standards for every category that is applicable to the project scope (no certification required). • Third Party Financed and/or Delivered Projects (Including Pub!ic Private Partnerships/ P3s): Must meet same Performance Standards as CIP projects. NEW requirement for mandatory analysis of feasibility for rooftop solar installation, use of non-potable water, avoidance of natural gas use, and EV charging. • Leased Spaces (NEW): o o o For non-City tenants leasing space in city-owned buildings which receive City assistance. LEED Silver or Austin Energy Green Building 3 Star is required, if the scope allows. For non-City tenants leasing space in city-owned buildings which do not receive City assistance, meeting the intent of LEED Certified or Austin Energy Green Building 2 Star is encouraged For City tenancy leasing space in non-City-owned buildings, a list of criteria or preferences for consideration when choosing leased buildings or spaces is included. Unique Projects and Paired Rating Systems The policy guidance provided is designed primarily for occupied buildings and vertical construction projects, as well as PARD projects over $2 million. For other project types such as unoccupied buildings, parking garages, infrastructure, or projects including a significant landscape component, projects are encouraqed to consider alternative rating systems OR pair these with LEED/ AEGB ratings. Below are some examples. New rating systems continue to emerge in the marketplace, (see "Outstanding Issues" at memo end.) a) *Sustainable SITES Initiative for landscape-oriented projects, b) *WELL Building Standard, c) Living Building Challenge, 3 d) ParkSmart for parking structures, e) Envision for infrastructure projects, f) CEEQUAL for civil engineering projects, g) GreenRoads for roadways and trail projects. * These rating systems are specifically designed to pair with LEED certification. Outstanding Issues Several design issues and opportunities merit further consideration for future policy updates. These include: 1) Other Building Standards: Several City of Austin projects currently underway are utilizing other building rating systems. These include the WELL building standard being used at the Development Services Center and Austin Energy Headquarters. Based on the post-occupancy experience and accrued benefits, the City of Austin may wish to add such standards to green building policy mandatory requirements in future. Further analysis of feasibility of such policy changes should be taken into consideration. 2) Existing Facilities: Existing facilities periodically require retrofits to replace or upgrade equipment, to ensure that building systems are performing well and are able to achieve energy and water efficiency. Improvements to space heating, ventilation and air conditioning (HVAC), water heating, insulation, plumbing fixtures, irrigation systems, energy control systems, and lighting are common retrofit measures. Further consideration of desired performance standards for existing facility performance and identification of funding mechanisms to ensure that existing facilities can meet desired policy thresholds is needed. 3) Public Art: The Art in Public Places requirement for eligible projects to allocate 2% of capital budget to commission or purchase art for the site, does not currently have a corollary for P3 projects. Commissioning or acquiring works of art is currently problematic for P3 projects due to challenges with the artist selection process, funding availability, and project delivery model whereby the City purchases a building from a developer. The Art in Public Places Panel discussed this topic at their December 2nd, 2019 meeting and expressed concern that the Art in Public Places ordinance does not apply to City construction projects created through this new capital delivery model. The Austin Arts Commission also discussed this issue at their Dec. 9th, 2019 meeting and formed a working group to Investigate development of a policy to guide application of the percent-for-art ordinance to city projects delivered under the P3 process. improvement Questions For any questions or clarifications, please contact: Lucia Athens, Chief Sustainability Officer OR Janice White, City Architect, Public Works Department.

Organizations Affected The following organizations involved in City of Austin CIP and other City facilities related activities are expected to be guided by this policy: • All City Departments and Offices and any party responsible for financing, planning, designing, developing, constructing, renovating, occupying, managing, or decommissioning buildings of which the City of Austin will be primarily responsible for through ownership and/or operations shall meet the requirements of this policy. • All City Departments and Offices and any party responsible for leasing space to City entities in non-City-owned buildings. • All non-City entities involved in financing, planning, designing, developing, constructing, renovating, occupying, managing, or decommissioning buildings of which at least 50% of the project funding (exclusive of land costs) is provided by the City of Austin OR which the City will assume responsibility of and/or pay for operations, maintenance, or utilities within 10 years shall meet the requirements of this policy (or an alternative standard as approved, consult the Public Works Department’s Project Management Manual for process and guidance). • All non-City entities occupying City-owned buildings or constructing facilities on City-owned land shall meet the requirements of this policy (or an alternative standard as approved, consult the Public Works Department’s Project Management Manual for process and guidance). • S.M.A.R.T. Housing™ developments are subject to the S.M.A.R.T. Housing™ Policy Initiative and not subject to the policy requirements stated here. D. Key Policy Priorities The requirements outlined below in Section E are intended to set forth minimum expectations and performance standards. Project teams are encouraged to meet higher levels of certification or rating and explore strategies for maximum building performance whenever feasible and allowable within a project budget. The City strongly encourages prioritizing and incorporating the following strategies for all applicable projects: Site Selection Strategies: Choosing the right site can have a significant impact on the overall enjoyment and accessibility of a building as well as the carbon footprint of its users and occupants. • Project locations that minimize transportation impacts and/or limit travel distances; including easy access to public transit, bicycle, and pedestrian amenities and serviced by City of Austin shuttles. • Project locations in Imagine Austin Activity Centers and Corridors with walkable access to shopping, dining, and community services such as post offices, healthcare, and affordable high- quality childcare services. Net Zero and Low Carbon Performance Strategies: The City of Austin has the goal to achieve net-zero community wide greenhouse gas (GHG) emissions by 2050 and aggressive performance goals for water and waste. Meeting such targets is ambitious and may 9 incur significant project costs but can also contribute to operational resiliency. The following are net- zero and low carbon strategies that are applicable to the project types covered by this policy. • Where feasible, design the project to achieve net-zero energy, water, and/or waste performance, as defined by LEED, AEGB or other building standard being utilized. • For new construction or building renovations that involve roof replacements, incorporate the installation of rooftop solar or use of solar-ready design practices, as determined by the feasibility analysis required in Section E. • For new construction or building renovations that involve HVAC or hot water system replacements, incorporate building electrification (avoidance or disconnection of natural gas), as determined by the feasibility analysis required in Section E. • For new construction, provide dual plumbing or systems for non-potable water sources, as determined by the feasibility analysis required in Section E. • Provide EV charging stations (especially if intended for City fleet vehicles) or EV-ready design, as determined by the feasibility analysis required in Section E. • Provide building amenities for employees that encourage alternative transportation such as bicycle storage, showers and lockers, or the ability to install these in the future. • Provide water bottle refilling stations. Health and Wellness Strategies: The environment in which a person spends their time can have a significant impact on their physical and mental health. Acknowledging that a majority of people’s time is now spent indoors, “healthy buildings” seek to create indoor spaces that promote the overall health and wellbeing of occupants. Benefits include increased mood, satisfaction and productivity for building users with decreased absenteeism and healthcare costs. The following are healthy building strategies that are applicable to the project types covered by this policy. • Where feasible, design the project to achieve WELL Building certification - The WELL Building Standard is the first and most comprehensive standard to focus solely on the health and wellbeing of building occupants and is designed to work harmoniously with LEED and other green building standards. • Design stairs that are prominent, easily accessible, and aesthetically pleasing, in order to encourage stair use. • Offer health and wellness amenities to employees such as gyms, huddle and phone rooms, wellness/mothers’ rooms, kitchens, breakrooms, healthy food vending or food trailers, and access to outdoor recreation. • Provide non-smoking facilities or designated smoking areas, in accordance with the City’s Smoking in Public Places Ordinance. • Maximize views and natural daylight by allowing for open space with high celling heights and • access to natural daylight for the many rather than the few. Limit hardwall and enclosed spaces, including limiting the height of solid panels around workstations and overhead cabinets that block natural light. If enclosed offices or spaces are necessary, they should be situated towards the interior of the floor plate so that they do not obstruct window light or views and they should incorporate glass fronts to maximize the transmission of light, whether from daylight or internal lighting. • Provide multi-use areas for collaboration, meeting and conference spaces, and common areas with access to large exterior windows, views and natural light. • Have centralized copy, printing, mail rooms, and landfill, recycling, and compost collection areas that encourage employees to get up and walk around. 10 • Employ Green Housekeeping standards and Green Procurement standards for common office- related items, such as paint and carpet, and use Green Seal products and services. Sustainable Landscape Strategies: Sustainability does not stop at the front doors. Sustainable landscapes provide numerous multi-benefits for the environment, property owners, and communities. Thoughtfully designed landscapes can positively impact building and landscape performance, maintenance, and aesthetics as well as promote human and ecological health. The following are site and landscape strategies that are applicable to the project types covered by this policy. Incorporate green infrastructure and innovative stormwater facilities such as biofiltration ponds, rainwater harvesting, porous pavement, vegetative filter strips, native landscapes to achieve carbon sequestration, and facility design to allow ongoing monitoring of these systems, as noted in Resolution No. 20071129-046. Consult the Public Works Department’s Project Management Manual for guidance. E.

Notes The following notes are applicable to all the above policy requirements: 1. The project team shall have the discretion to choose between utilizing LEED or AEGB rating systems for buildings, as allowed for in the Performance Standards described above. 2. The project team shall submit for approval (consult the Public Works Department’s Project Management Manual for process and guidance) the rating system under LEED or AEGB that they believe is most appropriate for the project. For example, LEED has rating systems for New Construction, Core and Shell, Existing Buildings, and Commercial Interiors projects. In most cases, the LEED Core and Shell rating system should only be used when it is paired with the LEED Commercial Interiors rating, otherwise it may lead to the City owning and/or occupying buildings that provide limited benefits to the end users. 3. 4. The LEED Campus Guidance is encouraged to be utilized in cases where there will be multiple LEED certified buildings on a single site under the control of a single entity, for example a campus of multiple office buildings or the airport complex. 5. As the City has the need to remain agile and flexible in its real estate transactions, the policies pursuant to leased spaces and third party financed and/or delivered projects may be considered and included as “objectives to be negotiated”. G. Unique Projects and Paired Rating Systems For projects outside the scope of this policy, design teams are encouraged to research and pursue alternative sustainability ratings. Additionally, projects that fall within the thresholds of this policy are encouraged to pair the requirements above with additional rating systems in order to achieve higher levels of overall project performance and community benefit. Some examples of alternative or additional rating systems are: • *Sustainable SITES Initiative for landscape-oriented projects, • *WELL Building Standard, • Living Building Challenge, • ParkSmart for parking structures, • Envision for infrastructure projects, • CEEQUAL for civil engineering projects, • GreenRoads for roadways and trail projects. * These rating systems are specifically designed to pair with LEED certification. 16 H. Financial Incentives The City and its representatives or partners should pursue all federal, state or local incentives to facilitate the implementation of Green Building Policy elements and overall project goals, as applicable.
