GREEN HIGHLIGHTS
A Roof overhang allows energy-efficient— but generous—south-facing windows to maximize solar gain in winter and minimize it in summer.
B A south-facing dormer reduces the need for artificial light. It captures the low winter sun and projects it onto the thermal mass of the masonry fireplace.
C The home is designed to be built with 6 1/2” SIPs for R-40 walls; 8 1/2” SIPs result in an R-64 roof.
D Slab-on-grade construction provides a large area of thermal mass to store solar gain.
E Additional winter heating uses a high efficiency, 95% AFUE boiler to warm the in-slab radiant heat.
F The 20 SEER air conditioning includes high-velocity duct work.
G Engineered wood headers and I-joists use less lumber and are manufactured from fast-growing, renewable trees.
H The design calls for durable fiber cement siding.
