This passive solar home is slated to be certified LEED platinum. During the deconstruction of the existing home, reusable materials were collected and documented. Through the use of super insulated SIP wall systems (R40) and passive solar design, DA + UD worked to achieve a highly energy efficient home. The main interior spaces flow into a south facing solarium, spreading natural light throughout the home.GREEN DESIGN ELEMENTS:Passive solar design — Reused and recycled materials gathered from demolished house; including roof tiles, windows, doors, light fixtures, casework, fixtures and faucets, appliances, flooring and trim. — Foundation walls, brick chimney and basement slab crushed and used for future backfill drainage on site. — Structural Insulated Panel System (SIPS) panels and highly efficient window systems. — Geothermal heat pump and HRV system. — Rainwater collection for onsite irrigation, native plantings. — Energy Star appliances.
