ARCHITECT Hays + Ewing Design Studio

Wooler Mills House

The first misconception about going solar is that it is expensive.

The second is that it requires insanely complicated panels, transformers, and batteries. “We

needed something simple, a way to use solar to cool the house more than anything,”

explains Christopher Hays, principal of Hays + Ewing Design Studio, which he runs with his

wife, Allison Ewing.“That’s how we were drawn to a passive solar setup.”

Exploring the Solar Systems

For the past 30 years, we’ve been teased with

the promise of plentiful solar energy. But for

most of us, nerdy solar calculators and

watches are as close as we get to realizing

this promise.

Passive solar systems use sunlight to warm or cool a house without the use of electrical or

mechanical equipment, and are organized around the creative use and placement of

materials such as heat-retaining concrete floors, sun-blocking louvers, and ventilation

systems that naturally distribute air throughout a room or house. Because they use no

additional energy beyond sunlight, passive solar systems have no operating costs or

environmental impact and can cut energy costs for decades.

For their passive system, Hays and Ewing worked with a day-lighting consultant to study the

trajectory of the sun throughout the year, plotting its penetration inside the house during

each month. Fixed louvers were installed over windows to provide shade areas during

summer. As the sun moves in winter, direct sunlight flows into south rooms, providing heat.

For south-facing windows, Hays and Ewing installed three-foot overhangs and light-filtering

trellises. High-density Plycem panels work like concrete to retain daylight heat and

distribute it in the house throughout cool nights, keeping the architects warm inside the

house.

Using natural convective currents, fresh air flows through the living areas downstairs and

exhausts through the second-story windows. Windows upstairs at each end of the east-west-

running hallways allow for cross ventilation.

“Since this is a passive system, it doesn’t completely take care of the temperature in the

house,” explains Hays, “but it does protect a large degree—and that makes it totally worth it.”
