Year Built: 2002

Highlights

• One of the earliest multifamily LEED certified buildings (LEED Gold)
• Designed to be off-grid, generating electricity from solar panels during the day and from a gas turbine at night
• Designed to be an interactive closed-loop building; heat exhaust from the gas turbine is used to pre-heat the hot water
• Passive cross-ventilation utilizes prevailing winds rather than active air conditioning

Community Corp. Retrofits

• Replaced all toilets with ultra-high efficiency toilets using less than 1 gallon per flush
• Retrofitted all lighting to high-efficiency LED lighting to lower electricity use at the property
• Replaced standard boiler (~60% efficient) with high-efficiency condensing boiler (+90% efficient)

Bahamas Apartments

Year Built: 1950s

• Replaced single pane, metal frame windows with double pane, UV protected, argon filled, vinyl frame high-efficiency windows.
• New windows reduce heat gain from the sun and also provide sound insulation from the busy street that fronts the apartment building
• Installed blown-in cellulose insulation to reduce heat gain from the sun and also provide sound insulation. Insulation keeps out the heat in the summer and keeps it in the winter.
• Retrofitted all lighting to high-efficiency LED lighting to lower electricity use at the property
• Replaced standard boiler (~60% efficient) with high-efficiency condensing boiler (+90% efficient)
• Replaced asphalt shingle roof with high-efficiency Energy Star foam roof. New roof provides insulation as well as sun reflectivity to reduce the heat gain in the units
• All accessible hot water pipes insulated to commercial grade fiberglass insulation level
• Pipe insulation helps reduce heat loss in central systems from the boiler to the individual fixture within the unit.
