Received a call from Dexter recently. He shared how thrilled he is about how the auto repair shop performs. He never had to turn the heat on through this past winter. Though  a radiant system was installed in the slab –  he really wanted a ‘warm’ experience having spent dozens of years on an unheated shop floor. He just didn’t need it. And he rarely turns on the lights during work days (unlike his previous shops). The south window wall + high windows around the east and north give plenty of general lighting. Dexter’s Shop is a good example of simple passive solar design. Not needing and automotive shop? Passive solar design is applicable to most any building.
