Item 4a-Recommendation Regarding CAP Funding of Weatherization_Lanetta Cooper original pdf

Thumbnail of the first page of the PDF
Page 1 of None page

RECOMMENDATION NO.____ Recommend that the CAP program no longer fund weatherization Recommendation: The CAP program should no longer fund a weatherization program. Reasoning: The CAP program provides billing assistance through the use of a waiver of certain utility charges and a 10% discount on the remainder of the electric utility bill. There is a waiting list of AE customers whose household incomes are at 200% or below federal poverty guidelines for that program. Removing the economic burden of the weatherization program from the CAP program would free up monies to provide bill assistance to more AE’s low and low-moderate income customers in need. Further, the weatherization program has consistently been characterized by AE as an energy efficiency program. As such, it should be in the energy efficiency program funded with EE rates.

Item 4b-Motion to Reconsider Recommendation Regarding Properties Serving Low and Moderate Income Customers_Carol Biedrzycki original pdf

Thumbnail of the first page of the PDF
Page 1 of None page

MOTION TO RECONSIDER PREVIOUS RECOMMENDATION Recommendation: Amend the June 12, 2015 interim report recommendation referring to rental properties that serve low and moderate income customers as follows: Change: “Earmarking Specific Funding from Multi-Family Energy Reduction Program on Low and Moderate Income Customers -- Utilize at least 50% of Austin Energy’s multi-family budget to incentivize energy efficiency retrofits on multi-family properties where at least 50% of the households have low and low-moderate incomes.” To the following: “Earmarking Specific Funding from Multi-Family Energy Reduction Program on Low and Moderate Income Customers Utilize at least 50% of Austin Energy’s multi-family budget to incentivize energy efficiency retrofits on multi-family properties that receive affordable housing subsidies from the federal, state, city, or county government or properties where housing choice vouchers are accepted as a form of payment. Explanation: The wording of the current recommendation stating that 50% of the units must be occupied by low income customers is a standard that may be difficult to document. By establishing readily identifiable types of affordable housing as categorically qualifying as low and moderate income the administrative burden is greatly reduced. The City of Austin is home to 186 publicly subsidized apartment properties, providing approximately 18,500 rental units with affordability requirements. These requirements are triggered by federal, state, and/or local funding sources, including Low Income Housing Tax Credits, Project Based Rental Assistance, HUD Direct Loans (Section 202 or Section 811), and HUD insurance.1 In addition, there are approximately 6,200 housing choice vouchers available.2 Including subsidized housing and those that accept housing choice vouchers provides a substantial target market and focuses limited resources for multifamily energy efficiency benefits to low and moderate income consumers. By working with the Housing Authority, the Housing Finance Corporation and other affordable housing administration offices Austin Energy can closely coordinate its energy efficiency programs with affordable housing renovation schedules and reach out to private properties that accept housing choice vouchers. 1 Taking Action: Preservation of Affordable Housing in the City of Austin, July 2014, Prepared by: HousingWorks Austin, Prepared for: Austin Housing Finance Corporation, City of Austin p. 8. 2 Ibid.

Item 4c-Demand and Energy Savings Goals for Austin Energy_Cyrus Reed original pdf

Thumbnail of the first page of the PDF
Page 1 of None page

1 I. Demand and Energy Savings Goals for Austin Energy Recommendation: The Low-Income Consumer Task Force reaffirms the goal that Austin Energy continue to meet its 800 MW peak reduction goal by 2020, and recommends that Austin Energy pursue achieving at least another 200 MWs of peak reduction in the next four fiscal years (2021-24), subject to availability of technology, programs and budgets. Thus, the Task Force believes assuming adequate support from council this goal is readily achievable. In addition, Austin Energy should continue to study achieving an even greater level of peak reduction, such as 1200 MWs by the end of 2024. Expanded loan programs and the availability of PACE may allow the utility to achieve this ambitious goal or at least get nearer to these ambitious goals. Backgrond. On December 11th, 2014, the City Council established a new demand reduction goal for Austin Energy, reaffirming the goal of reaching 800 MWs of peak demand between 2007 and the end of 2020, and requiring at least an additional 100 MWs of peak demand reduction by the end of 2024. As part of this new overall 900 MW goal, Council required that at least an additional 100 MWs be acquired from demand response. Although the Council set the new 900 MWs of demand reduction by the end of 2024, Council was careful to direct Austin Energy to view this goal as a minimum, and therefore established two additional “targets.” First, City Council told Austin Energy to seek to achieve a greater amount of demand reduction, by stating that subject to further study, technological development, progress toward goals and rate and budget considerations, Austin Energy should consider the potential to reduce an additional 100 MWs of demand reduction through additional energy efficiency and demand response programs by the end of 2024. Secondly, City Council directed Austin Energy to study whether an even more ambitious goal of 1,200 MWs by the end of 2024 was economically and technically achievable. The Low Income Task Force believes that assuming improved technologies, programs and a budget commitment roughly consistent with current budgets in the $30 million range, achieving 1,000 MWs by the end of 2024 is readily achievable. Further study and analysis of course is needed. In addition, with the development of new programs like PACE, improved loan opportunities, and potentially other financial mechanisms like On-Bill Repayment, Austin Energy should study the potential to achieve …

Item 4d-Revised Recommendation on Building Codes_Cyrus Reed original pdf

Thumbnail of the first page of the PDF
Page 1 of None page

Recommendation on Building Codes – Revised Version August 10, 15 The Task Force finds that continued improvement in base energy codes to reduce peak and overall energy use is of benefit to low-income and middle-income residents and to Austin Energy overall. Austin Energy has consistently worked with the City and its departments to improve base energy codes every three years, making new homes and remodeled homes and other buildings more energy efficient. By reducing the energy use of new and rehabilitated buildings Austin can lower emissions and water use from existing fossil fuel plants, reduce the need to buy expensive peak power off the market and potentially provide demand response capabilities to meet peak demand or even participate in energy markets. The Task Force reaffirms the goal of making new home construction in Austin, Texas to be net-zero energy capable by the end of 2015, while recognizing the challenges with fully meeting this goal. We recommend in 2015 that Austin Energy work with the relevant advisory committees, city departments and city council to adopt: 1. The 2015 IECC codes for residential construction, including local amendments to reach the net-zero-energy capable homes approved by City Council in 2007. The Task Force believes that the net-zero-energy capable home goal is achievable, but recognizes that certain homes will be unable to meet this goal in 2015 depending on whether the home is all-electric or includes gas heating and gas water heating, the size of the home and other issues like orientation of the design and the behavior of occupants. Assuming Austin Energy recommends and city council approves an updated more energy efficient code for new and remodeled homes, Austin Energy should continue to consider other amendments and programs to fully realize the net-zero capable homes goal beyond 2015; 2. To further the goal of net-zero energy capable home, Austin Energy should consider local amendments to the energy code and suggest amendments to other building codes to encourage the adoption of new technologies like solar PV, demand response, energy storage and electric vehicle charging technologies as appropriate. As an example, Austin Energy should work with the electrical code to assure that there is sufficient panel capacity to allow for EV charging stations. 3. Encourage the widespread adoption of solar PV technology by: a. Adopting a version of Appendix RB of the 2015 IECC which requires that all new homes be “solar-ready.” Austin Energy should …

TO: Low Income Consumer Advisory Task Force (LICATF) FROM: Denise Kuehn, Energy Efficiency Services Director DATE: August 14, 2015 SUBJECT: Questions Concerning Questions Submitted by Lanetta Cooper in July 17, 2015 Low Income Consumer Advisory Task Force 1. The 2012 GDS report provided the Task Force stated at p. 2 that AE uses “Salesforce.com” to store data. a. Please explain how AE uses “Salesforce.com” including an explanation of what data is stored and how it is stored. Answer: Salesforce.com is a customer relationship management tool. It allows data to be accessed by certified and verified users as needed for their roles. Data is stored via a secure cloud service monitored in real time by Symantec and verified by TRUSTe. These storage protocols meet or exceed City protocols. Access is available to only those with authorized user names and passwords who have completed Salesforce training. b. How does, if at all, AE track pre and post weatherization installations consumption involving its customers (include energy performance star) Answer: Consumption analysis is based on one of two methods: billing data or daily data. The option of which data source is used is dependent on data availability and the transitory nature of the customers. c. Has AE formatted its billing histories so that it can pull up by energy efficiency program pre and post EE program installations consumptions? If not, why not and what would AE need to do to be able to create a data base that could be accessible by EE program. (I am assuming the use of billing data aggregated by EE program and not individual customer data). Answer: AE is currently developing a data warehouse and related data structures to meet reporting needs. Data for energy efficiency analysis will reside in this data warehouse for ease of reporting. The data warehouse is in its initial stages of development. The goal is that all program data will be housed and available for analysis in this centralized location by FY2017. Reports will also be available using the new Direct Technology rebate processing tool in which the before and after usage of the customer receiving the rebate will be available allowing AE to verify the cost benefit effectively. The Direct Technology tool will process and track the energy, demand reduction savings and rebates for sixteen Customer Energy Solutions programs scheduled to be implemented fall 2015. 2.

1 TO: Low Income Advisory Task Force FROM: Denise Kuehn, Energy Efficiency Services Director DATE: August 14, 2015 SUBJECT: Questions Concerning the Changes of Costs Associated with AE Weatherization Program Over the past thirty years, Austin Energy has weatherized over 17,000 homes for low income customers. Cost of providing the weatherization program has changed due to two main contributing factors: the changes in the qualification criteria associated with resources available and the need of the community defining the type and costs of the measures provided. The qualification criteria of customers receiving low income weatherization has changed over the years based on federal and local influences. The federal government subsidizes many low income programs in conjunction with the City of Austin. This criterion has been based on the federal poverty rate which has varied from 100% to the current 200% and below in order to qualify. Additional criteria have been established for ensuring potential customers have not participated in the program over the past ten years. AE further qualifies based on the value and square footage of the home. In addition, AE partners with other city departments, utilities and non-profit organizations to reduce the costs in order to align resources. AE’s partnerships to address low income needs in the Austin area range from referrals and process enhancements to implementing home improvements for other entities. AE exchanges referrals with several entities such as Austin Water Utilities, Neighborhood Housing and Community Development (NHCD), Travis County, Housing Repair Coalition (collaboration of numerous non-profit and city organizations) and various other non-profit organizations. Over the past year, AE has worked with AWU, NHCD, Purchasing, Health and Human Services and non-profit agencies to develop a standard intake form and enhance communication. In addition to referrals, AE provides administrative support for AWU-provided water savings devices at no charge to AWU. AE provides energy saving weatherization while Neighborhood Housing provides structural repairs when federal grants are available. NHCD combines different grants to provide services such as lead removal and roof repairs to an average of 200-250 unique homes per year. NHCD receives a 10% administration fee to coordinate the in work for Austin Water on these homes. AWU provides the water saving devices and pays for the installation to NHCD. Weatherization is one of the many services the City of Austin provides low income customers. Basic services such as insulation and air infiltration are utility industry standard. As more …

The questions and related responses follow. Please note that when mapping program data, premise addresses are used. Should a mailing address be captured that is outside of the AE service territory, it is not mapped. The majority of the responses are related to data provided to the Austin American Statesman in terms of program reach by zip code. Zip code data cannot be read in isolation because there are other factors to consider such as the overall population of the zip code, housing stock, and the percent of poverty per zip code. Statistically, many of the zip codes for population, percent poverty and rebates are within the norm. It is not a universality that “wealthier residents” get more in rebates than other customers. Additional factors, such as dwelling type, age of home and home ownership, play into the eventual participation in rebate programs. For example, a zip code dense with multifamily properties may “map” into a lower participation rate because the property with multiple apartment units is counted as one rebate (for a commercial customer) when the one rebate has actually served hundreds of residential customers. Overall, the programs are meeting the needs of our customers based on their ability and need to participate. 2 3 4 Reponses 1. The time periods varied by program but covered from program inception through 2014. Data was based on residential programs only. Please note that data provided on map may not be complete program data but only data that could be mapped accurately. 2. The map captured unaudited rebate data from program inceptions through 2014 and totaled $181,189,101. Please note that data provided on the map may not be complete program data but only data that could be mapped accurately and where financial records exist (for example, for the period 1982 – 1995, there is not separate accounting for low income weatherization, or other programs). 3. No non multifamily commercial rebates were included. 4. NA 5. See table of unaudited data below.

1 MEMORANDUM TO: Low Income Consumer Advisory Task Force FROM: Liz Jambor, Customer Energy Solutions DATE: August 21, 2015 SUBJECT: Response to Request by Lanetta Cooper to Extend Previous Data Set Lanetta Cooper requested an extension to a data set provided earlier in the LICATF process. This data set included the before and after kWh usage and payment status of customers in the weatherization program. The original data set contained 32 customers. Table 1 provides the original data set. The updated data, found in Table 2, set contains 9 customers. These are the customers that have consistently resided at the weatherized dwelling across the time line from October 2013 through July 2015. There is not consistent savings, post install, across all customers or across all months. It appears that there may be some behavioral impacts to energy savings post-weatherization. 2 Table 1.

1 MEMORANDUM TO: Low Income Consumer Advisory Task Force FROM: Liz Jambor, Customer Energy Solutions DATE: August 21, 2015 SUBJECT: Comparison of Energy Savings for AC versus No AC Replacement A question was posed by the Low Income Consumer Advisory Task Force concerning the energy savings differences between weatherized homes that had the air conditioner (AC) replaced as compared to homes that did not. The table below compares homes completed in 2013 when AC replacement was part of the weatherization measures. The sample size is extremely small, given the transitory nature of the population. Any extrapolations beyond the current data should be made with extreme care. As indicated by the data in the table, there was greater savings for homes with an AC replacement. However, this savings came at a greater cost per kWh. For this small number of homes, there is greater savings for the customer at a greater cost to the utility. Number of Customers in Continuous Residence Mean kWh Saved Mean Improvement Cost Dollars per kWh Saved AC Replacement 5 1,666 $6,409.25 $3.85 No AC Replacement 15 1,201 $2,400.99 $2.00

Item 5b-Staff Response-Factors influencing decision to retrofit existing window units with central ac original pdf

1 MEMORANDUM TO: Low Income Consumer Advisory Task Force FROM: John Umphress, Green Building & Sustainability Consultant, Sr. DATE: August 18, 2015 SUBJECT: Factors influencing decision to retrofit existing window units with central a/c Thank you for allowing Michael Husted and I the opportunity to come speak with the task force about energy code issues, hopefully you found it helpful. During the discussions that took place as part of that meeting the subject of the efficacy of window units for air conditioning was brought up. The discussion centered upon a narrowly defined example, and didn’t lead to a broad discussion of the factors contributing to a decision as to whether a given situation would merit replacing a window unit with another a/c option. It is fair to say that a split or central system is a better solution for new construction. The decision to “upgrade” a window unit with either a split or central system in an older building is much more complex, requiring a detailed analysis of each building, and weighing a number of potential factors to determine the most effective approach for the customer. Unfortunately, it is difficult to develop a prescriptive approach that appropriately addresses all of the potential variables that may need to be considered when looking at potential a/c upgrades. In general, weatherization looks at improving the building envelope and/or the mechanical systems. Each house presents its own unique situation, and striking the appropriate balance of investments between the two areas (envelope and mechanical) for the specific premise is paramount for reaching an optimal solution. In addition, we generally reach a point of rapidly diminishing returns, where additional money spent doesn’t result in correspondingly large savings for the customer. To the contrary, they often face the unintended consequence of spending more money. Anecdotal information derived from the low-income weatherization retrofits performed by Austin Energy showed that some residences experienced significantly higher energy bills after replacing window units with central systems. This led to higher bills, and also to higher demand for the premise. This was generally attributed to the central system cooling the whole house all of the time and having a higher overall cooling capacity, as opposed to window units generally cooling a smaller space and needing less energy, particularly if only one small system was running at any given time. There are a myriad of factors that should be considered when deciding which …
