Materials and Design Strategy


Primary construction materials are regionally sourced dimensional lumber and a fiber cement rainscreen exterior panels. Interior finishes feature products made from sustainably harvested woods, rapidly renewable resources, and high recycled content. Wherever possible, locally sourced materials were selected. Drought-resistant native plantings are used throughout the site. Turf is minimized and a Drought Tolerant Fescue ground cover is used to eliminate and reduce irrigation needs. Rainwater harvesting is used for to irrigate gardens and plantings.

Special architectural measures:

Building design optimized convection air flow allowing warm air to move from the lower floors of the home to the top of the upper floor where clerestory windows provide for venting excess heat. The southern façade is glazed to take advantage of solar heat gain in the winter. Deep overhangs and recessed window reduce heat gain in the summer months. Daylighting is maximized to reduce reliance on artificial lighting.

Building orientation and form are optimized for the solar PV and solar thermal arrays on each unit.

Indoor Environment Description:
The indoor environment has earned 14 of 21 LEED for Homes credits. No products containing VOCs were used in the building and there is no combustion in the building. Whole building energy recovery ventilation uses MERV 4 filters to remove any naturally occurring pollen and pollutants.
