Dave had just read in his Environmental Studies textbook that a North Carolina engineer and builder had discovered the secret of architecture - a technique for building homes that heat and cool themselves, without pollution. He took the textbook to show Chris, his wife. Where rising solar heated air provides and distributes energy Living/Dining/Kitchen can be open to the Sunspace when the house has "equalized". Visually divided from the dining room by the main beam The airlock entry provides a transition space and thermal break between the North Porch and the living room. The master bedroom is on the main level and has French doors opening onto the Sunspace The loft on the second level overlooks the Great Room. The internal window in the sunspace wall of the loft is lined up with a skylight in the sunspace to give natural light for this peaceful reading area. This is one of two upper level bedrooms. A window to the Sunspace adds light without heat loss. From the North entry - a simple, easy to maintain, country home.
