Protected, yet tuned in Karen Terry's house in Sante Fe, designed by architect David Wright, is perhaps one of the most compelling passive designs. Stepping down its hillside site in four tiers, it nestles low into the ground. Thick adobe sidewalls create a strong sense of shelter and its banks of windows look resolutely to the sun. The image is very much of a house attuned to sun and earth. Rather than providing the convenience of a constant indoor temperature regulated by a thermostat, a passively solar-heated house may go through an air temperature flux as great as 20ºF per day. People learn to live with this flux. Living in a solar house is a whole new awareness, another dimension. I have the comfort of a house with the serenity of being outdoors—protected, yet tuned in.
