1 Multifamily Retrofits The Path Forward for Multifamily Energy Efficiency Programs Charlie Taylor, Scott Campbell, and Christa Shute Thursday February 4 th, 2016

2 WHO S IN THE ROOM? Property owners, developers Design community (Architects, Engineers, etc.) Energy Efficiency Program Staff Policymakers, consultants, Non-profits etc. Implementers, builders, contractors etc. Others? 2

3 NORTHEAST ENERGY EFFICIENCY PARTNERSHIPS Accelerating Energy Efficiency Mission Vision Accelerate energy efficiency as an essential part of demand-side solutions that enable a sustainable regional energy system Region embraces next generation energy efficiency as a core strategy to meet energy needs in a carbon-constrained world Approach Overcome barriers and transform markets via Collaboration, Education and Enterprise One of six regional energy efficiency organizations (REEOs) funded by the US Department of Energy (US DOE) to link regions to US DOE guidance, products and programs 3

4 REGIONAL CONTEXT -NEEP s High Performance Buildings team first began it s multifamily retrofit project in Assisted Efficiency Maine in efforts to set up a one-stopshop, organized a regional working group, held focus groups for landlords and tenants, and disseminated best practices. -Published a report in 2014 on strategies to advance energy efficiency in small and mid-sized multifamily buildings. -Focused on small to mid-sized multifamily buildings (5-20 units). -Currently working on a collaborative project to advance the efficiency of multifamily buildings across the country with four other REEOs. 4

5 NATIONAL BEST PRACTICES REPORT Set for release later this year, will contain: -Best practices derived from experiences from 5 different regional organizations providing technical guidance and support to multifamily programs across the country. -Policy and program implementation recommendations -Case studies 5

6 REGIONAL MULTIFAMILY MARKET ASSESSMENT Characteristics of the region s multifamily housing (5+ units): -Over 5 million multifamily housing units -Almost half was built before Overwhelmingly located in urban areas -A majority heat with natural gas -A quarter heat with oil 6

7 VERMONT MULTIFAMILY BUILDINGS Characteristics of Vermont s multifamily housing: 42% built before 1960 About 80% heat with oil or other unregulated fuels (propane, biomass, etc.) More rural, 26% located in rural areas compared to about 5% for the rest of the region. 7

8 REGIONAL BEST PRACTICES: SIMPLIFY! Refine the development of one-stop-shops for multifamily building owners Efforts to reduce the work needed from the building owner through the retrofit process: Create a single point of contact Streamline paperwork Clear, easily understandable audit reports Assign qualified contractors for implementation Include installation and savings verification 8

9 EXPAND PROGRAMS FOR DELIVERED FUELS Vermont is a leader in this space Huge opportunity for savings in multifamily buildings which are largely ignored in many states Nearly 1 million units in New England and New York heated with oil. Many large MF buildings heated with steam Funding mechanism needed in states with significant populations heating with oil and biomass 9

10 FINANCING Accessible financing is crucial to this market Public/private partnerships can maximize benefits for building owners Public entities can leverage funding by creating loan loss reserves or interest rate buy-downs which facilitate private investment On-bill and PACE financing enable building owners to bundle retrofit costs with existing bill/tax payments and typically have much lower default rates than other forms of debt 10

11 FACILITATE ENERGY DATA ACCESS Building owners need access to easily understandable building energy data Benchmarking in Energy Star Portfolio Manager, WegoWise, or a similar platform enables comparison between buildings. Automated data transfer through Green Button Connect My Data and similar services allow third party service providers to retrieve energy data on an ongoing basis This data should be accessible for tenants. Policies requiring disclosure of energy bills or benchmarking data to tenants give insight into the otherwise invisible energy attributes of the building. 11

12 GEOGRAPHICALLY TARGET AREAS WITH GRID CONSTRAINTS A vast majority of multifamily housing is located in urban areas Often grouped together by neighborhood Geo-targeting enables energy efficiency program staff and grid planners to work together to delay the construction of expensive grid infrastructure needed for load growth. There is value in investing in deeper incentives because of the savings realized by both the efficiency measures and the delay of more costly poles and wires alternatives. Most effective when paired with other DERs 12
