Multi-family housing (i.e., structures that house two or more dwelling units in a single building, such as town houses, apartment buildings and condominiums) account for one-third of all housing energy and 1/6 of the total energy consumed in California. Demand in this sector is expected to grow by an additional 25% over the next 10 years. Multi-family housing is a high priority sector for the Alliance for several reasons:

  • Substantial energy savings and greenhouse gas reductions are achievable within the state’s existing stock of multi-family housing.
  • As of 2007, approximately 50% of California’s low-income households - about two million households - live in multifamily dwellings.
  • A handful of owners and developers of portfolios of multifamily housing have the ability to effect rapid and cost-effective energy efficiency in thousands of residential units across the State.

The California Sustainability Alliance thus decided to focus its attention on encouraging large real estate owners and managers of existing multifamily housing properties to consider comprehensive portfolio approaches to cost-effectively greening all of their units. Within this section you will find information on opportunities for improved sustainability within the multifamily housing market, challenges to improving sustainability in this sector, and strate gies for overcoming these challenges and providing value to both owners and tenants.

The Alliance’s activities are guided by its Sustainable Communities Pilot Advisory Committee that helps to identify and characterize key barriers, and then to design and implement green multifamily housing pilots. The pilots tackle major barriers to sustainability, advancing strategies and tools to transform this high potential market. Four pilot programs, conducted in partnership with HUD’s Mark-to-Market Green Initiative, LINC Housing Corporation’s Housing Energy Program, BRE Properties, and Folsom/Dore Apartments, are highlighted in the case studies to the left.

HUD Mark-to-Market

Case Study: U.S. Department of Housing and Urban Development Mark-to-Market Green Initiative Program The benefits of green affordable housing address the fundamental needs of its residents: affordability and livability. According to the National Energy Policy Report, the energy burden on low-income households as a proportion of income is four times greater than it is for other American households. Greening affordable housing not only makes sense for residents — who can benefit from lower utility costs and healthier environments — but also for owners, who benefit from lower maintenance and operating costs.In response to this opportunity, the U.S. Department of Housing and Urban Development (HUD) launched its Mark-to-Market (M2M) Green Initiative for affordable housing in July 2007. The initiative was designed to provide an opportunity to replace inefficient building systems and equipment with sustainable, energy efficient, and cost-effective alternatives in conjunction with project renovation and financial restructuring actions supported through HUD’s Mark-to-Market program.. A nationwide pilot, the M2M Green Initiative provided financial incentives and technical support to property owners to facilitate energy and green invests and incorporate sustainability principles into ongoing property operations, repairs and scheduled equipment replacements over the next 20 years of the project’s life. Providing more favorable financing terms and enabling project debt to be restructured to accommodate green investments — even as rents are set to ensure greater long-term affordability for low income households — enables affordable housing owners to realize the green potential of the existing housing stock.After developing the Green Initiative pilot program, the California Sustainability Alliance provided valuable policy feedback to HUD by commissioning Strategic Energy Innovations (SEI) to evaluate the design and implementation of the M2M Green Initiative. The Alliance conducted a study of the current Green Initiative Implementation Guidelines and provided technical assistance to help properties assess their energy performance, identify energy efficiency and green building opportunities, integrate energy efficiency and green technologies into design plans, develop specifications for building performance, and verify building performance to ensure that owners gain the best return on the energy and green building investments.Sustainable opportunities identified include the following:

  • HVAC and Envelope
    • Wall A/C units
    • Common-area A/C
    • Roof-pack A/C
    • Cottage heat pumps
    • Packaged terminal heat pumps
    • Attic insulation
    • Windows
    • Roof/paint upgrades to reduce A/C loads
  • Other Energy Efficiency
    • Lighting
    • Ceiling fans
    • Elevator Motors
    • Refrigerators
    • Clothes washers
  • Water Efficiency
    • High-efficiency sprinkler heads
    • Xeriscaping
    • Drip irrigation
    • Hardscaping upgrades
  • Materials
    • Bamboo cabinetry
    • Natural linoleum floor tile
    • Low-VOC carpeting and paint
  • Solar
    • Solar thermal domestic hot water
    • Photovoltaics

The Alliance’s study recommends improving performance of the M2M green retrofits by upgrading technical and economic analysis requirements, improving utility monitoring requirements and providing more specific guidance for selection of qualified contractors. The study reviews the existing program guidelines and other HUD tools and programs to evaluate the effectiveness of the current M2M program.Download the Alliance’s Green Property Condition Assessment Recommendations for the Mark-to-Market Green Initiative.For more information on the HUD Mark-to-Market Green Initiative, visit the HUD website.

CASE STUDY: BRE Properties

BRE Properties, Inc. (NYSE:BRE) is a real estate investment trust that owns, develops, acquires, and manages highly desirable apartment communities in the West's most sought-after places to live, including 57 properties in California. BRE has a longstanding track record of successfully adapting to the marketplace and turning challenges into opportunities, so it is only natural that they decided to partner with the California Sustainability Alliance to increase the sustainability of their multifamily housing portfolio.

The process began in 2007 with preliminary assessments of five apartment communities that were deemed representative of BRE’s California portfolio. The assessments identified measures that could improve energy, water, and natural resource efficiency. Building upon these findings, BRE worked with the Alliance to characterize the types of equipment typically used in their apartment communities and to identify energy efficiency measures that might be applicable to the full portfolio of BRE’s properties in Southern California. Numerous retrofits and operating measures were evaluated, including:

  • Replacing pool pumps and motors
  • Installing pool covers
  • Replacing inefficient lighting
  • Replacing through-wall A/C units
  • Tuning up or replacing other inefficient A/C units
  • Reducing pool pumping hours
  • Resetting boiler temperatures

At a typical apartment community, these measures will save over 22,500 kWh of electricity and 5,000 therms of natural gas each year, and will pay for themselves in less than two years. If implemented at BRE communities across California, these efficiency measures will result in annual energy savings of over 1.3 million kWh of electricity and 230,000 therms of natural gas. Based on this analysis, the Alliance developed a set of recommended energy efficiency measures for use at BRE’s entire portfolio. To facilitate adoption of these measures, a “Keep It Green with Energy Efficiency” handbook of best practices was created. The handbook empowers BRE on-site staffs to make incremental improvements as they carry out regular maintenance, in addition to providing a business case for larger, more capital intensive retrofit programs.
