LEED Platinum in Vista, CA

Project Introduction
Project Name: North Santa Fe Apartments
Location: Vista, CA
Installed: 2016
Installer: Adroit Energy, Inc.

North Santa Fe Apartments is certified as Green Point Rated, with 201 points (Platinum level), and is part of the SDG&E California Advanced Home design program. It’s a high-performance development, with ratings approximately 40% above California’s energy code. The high efficiency reduces the operating costs for long term ownership, keeps the apartments comfortable in all weather, and mitigates utility costs for households so they can invest in their future. • Apartments include Energy Star appliances, heat pumps, pin fluorescent lighting. Roof-mounted solar thermal preheats water for the high efficiency gas-fired central hot water boilers. Similarly, photovoltaic panels will support at least 50% of the common area electric load.

Performing Above the California Energy Code Title 24 Standards
A LEED Platinum project, the North Santa Fe Apartments is an affordable rental community by the nationally recognized non-profit developer, Community Housing Works. Designed and Installed by Adroit Energy of San Diego, CA, a solar hot water system comprised of (8) SunEarth EP-40 Flat Plate Collectors will supply the hot water load for the demands of the project. The system also includes a photovoltaic (PV) system on the roof that will offset at least 50% of the common area load. The 68-unit development performs 40% above the California Energy Code Title 24 standards.
The City of Vista provided a 62-year ground lease for the site. Union Bank is the construction and permanent lender and is also the tax credit investor for the $16.6 million of low-income housing tax credits. The City of Carlsbad provided $370,000 of CDBG funds; additionally, financing included NeighborWorks funds which will be replaced by $670,000 of Federal Home Loan Bank of San Francisco AHP funds at conversion. Solar and energy program rebates, together with reimbursement from the City of Vista for community upgrades of the sewer in the public alley, complete the project funding.
