US DOE Recognizes Three CA Buildings for Sustainability The U.S. Department of Energy (DOE) recognized three buildings in California for their sustainability efforts in its Better Buildings Challenge. DOE representatives from Washington, D.C. toured these sites along with members of the management teams: Market Square in San Francisco A Better Buildings Challenge partner, Shorenstein Realty Services, was recognized for its leadership in energy efficiency at its Market Square property in San Francisco. DOE representatives viewed the property's upgrades including: new and modernized elevators, creative re-use of reclaimed materials in the historic lobby, indoor LED lighting retrofit, retrofitted chiller, updated HVAC system, energy-efficient appliances, and new LED lighting throughout the parking garage. Acquired by Shorenstein in 2011, Market Square consists of two buildings — 1335 Market and 1 Tenth Streets —joined by a landscaped plaza. The original building (1335 Market) is an Art Deco icon, formerly known as the Western Furniture Exchange and Merchandise Mart. In 2014 Shorenstein completed an extensive renovation to reposition the property into first-class creative office space with supporting retail. The redevelopment offers modern and state-of-the-art conveniences, while still maintaining the classic architecture of the buildings. Market Square is now LEED Gold and ENERGY STAR® certified. Los Angeles Unified School District Better Buildings Challenge partner Los Angeles Unified School District (LAUSD) was recognized for the energy productivity advances made in its schools. LAUSD set goals of reducing energy and water use by 20% over the next 10 years across its 70 million square feet of building space. LAUSD is the second-largest district in the nation and serves over 660,000 students with a portfolio of 1,200 schools and associated centers. DOE visited LAUSD’s Better Buildings Challenge Showcase Project Santee Education Complex to tour the campus’ energy upgrades. The 338,000-square-foot educational complex serves over 1,900 students and 145 staff, and operates as one of the highest energy-consuming facilities compared to the district’s average. To help reach LAUSD’s 20% energy consumption reduction goal by 2024, Santee made upgrades including interior and exterior lighting, an energy manage-
ment system, efficient domestic water heater and boiler, as well as the installation of occupancy sensors, and retrocommissioning the set points. Santee is on schedule to
achieve 30% annual energy savings based on seven months partial post-completion data. As a result of these upgrades, the school expects to achieve a 23%, equal to $195,000, annual cost savings. Multifamily Innovations DOE and the U.S. Department of Housing and Urban Development (HUD) recognized Tenderloin Neighborhood Development Corporation (TNDC) and Mercy Housing for impressive energy efficiency advances made in multifamily buildings. Both partners completed showcase projects and are on their way to meeting their goals of reducing energy use by 20% portfolio-wide over 10 years. Mercy Housing has 21 million square feet in its portfolio; TNDC has 2.3 million square feet and has also set a 20% water reduction goal. Representatives visited TNDC’s Better Buildings Showcase Project Alexander Residence (shown above) and Mercy Housing’s Better Buildings Showcase Project 205 Jones Street Apartments to tour the buildings’ energy and water upgrades. Each organization completed major energy and water efficiency improvements to these properties in San Francisco’s Tenderloin neighborhood. TNDC and Mercy Housing each implemented a combination of energy and water conservation upgrades, including a new solar thermal hot water system, energy-efficient steam boiler, thermostatic radiator valves and pipe insulation, LED lighting throughout tenant and common areas, low-flow water fixtures, and new ENERGY STAR® refrigerators and new washing machines.
