Kalos, meaning “beautiful and all that is good” in Greek, is true to its definition.

The 83-unit development, which serves a mix of seniors, families, and nonsenior individuals, has replaced a deteriorated site with dilapidated buildings in San Diego.

Developed by nonprofit Community HousingWorks, Kalos earned Platinum certification under the LEED for Homes Midrise Pilot.

A photovoltaic system provides virtually 100 percent of common-area electricity in combination with all-LED exterior lighting. A solar domestic hot-water system on the roof offsets 70 percent of residents’ water- and space-heating costs. A cool roof, breezeways, and good insulation offset the solar heat gain, eliminating the need for air-conditioning. And it uses 56 percent less water than a typical residential community, through sustainable landscaping, efficient irrigation, and low-flow plumbing features.

After failing to receive 9 percent low-­income housing tax credits, the team decided to move forward with 4 percent credits and bonds, which Union Bank purchased.

The $26.8 million project also received funding from the San Diego Housing Commission and the Redevelopment Agency of San Diego. In addition, it ­received utility company rebates and ­incentives.
