In Norwalk, Calif., Promise Energy installed a solar water heating system atop the Norwalk Tower, providing renewable heat for low-income senior residents in the 185-unit housing project. The solar system reduces the energy consumption of the entire building by over 7 percent.
The solar water system is part of a retrofit of the building developed by Preservation Partners Development (PPD) & Innovative Housing Opportunities. The building’s retrofit was funded by Low-Income Housing Tax Credits along with a loan from the US Department of Housing & Urban Development.
To meet financing requirements, PPD had to deliver a 20 percent improvement over current energy use, and with the help of the solar water heating system, the building now performs nearly 23.5 percent better than it did before.
