Efficiency

Photovoltaics and energy storage

The Rogers had not considering installing a photovoltaic array when they started the process of envisioning their new house. Their only request was to create a house that Stickley furniture would not feel out of place. We presented them with a detailed return on investment for solar, including an analysis of state and federal tax credits available. This and they fact that they could eliminate an emergency generator by adding a 14 kW Tesla Powerwall battery, proved that renewable energy with storage capacity was a sound financial decision. The Rogers can expect a return on their investment in less than 10 years, with their photovoltaic array easily having 15+ years of life left.

Performance

The house was designed to incorporate a number of high performance systems. The HVAC system was designed in-house to be the most efficient and appropriately sized system for the house and the client. The project was reported to the 2030 Design Data Exchange with the predicted energy usage intensity at 14.33 kBtu/sf/yr; a 65% reduction compared to the baseline, meaning that it is on (or ahead of) track to meet carbon emission reduction goals that we set when we signed the AIA’s 2030 pledge.

Design

Vernacular form

The T-plan, with its single-room width and elongated form is slanted on the lot to frame an extensive view of a monumental live oak to the east. Craftsmen era elements, such as exposed rafters, a low-pitched gabled roof, and inclined entry columns are reinterpreted for modern living. A long kitchen cabinet wall transitions into a craftsmen fireplace that incorporates modern geometry. The shed roofs slope to the south and open to the northern light, views of the pond and large live oaks. There is an extensive rain garden on the entry side with native plants that filter roof runoff and create an exciting entry sequence.

Exterior Spring Island Architecture

We are thrilled with the job that Jane and Michael did in designing our home. They really listened to us, marrying our design interests with the lowcountry vernacular of the region, as well as the opportunities of the building site.
