This solar-heated residence addition in Lexington includes a
solarium/family room, garage, master bedroom suite with bath, and dining room
extension. The new addition was angled
to face directly south and designed using a combination of energy
conservation techniques and a hybrid active/passive solar heating and cooling
system. Active solar components of the
system include: solar-heated domestic hot water system with roof mounted
collectors, hot water storage tanks in the basement, heat exchanger loop to
hot air distribution ducts, and a thermostat controlled fan-assisted hot air
distribution system from solarium to main house. The passive components consist of : large south facing glass areas in the solarium and
dining room passageway, thermal mass tile floors to absorb heat, moveable
sunshades and insulating shades for all windows, and design for a natural
convection loop between the first and second floors of the addition to allow
for natural distribution of heat in winter and cool air in summer. In addition, a wood burning stove has been
installed for backup heating. |
