Main house 48' x 30' (total 2,280 square feet) - 5 bedrooms, 2 1/2 bathrooms
Breezeway and garage not included in square footage

This Garrison is entered from the south. There are five bedrooms with the master bedroom and a study/bedroom on the first floor. There are two bedrooms, a study/bedroom and a balcony study on the second floor. The house has two and one half bathrooms.

To the south large windows provide direct solar gain in winter to both floors, substantially reducing your non-renewable energy needs. The south facing roof is ideally sloped to allow for the possibility of achieving zero net energy. We cover this roof with active solar thermal and solar electric systems. Zero net energy means your total energy usage and production are equal over the course of a year (see Production). The house can be built to allow these active solar systems to be added at a later date. A three season breezeway connects to the two car garage.

Garrison view on a fall day at 3 p.m. at which time you will have received 90% of the day's solar energy.

This Garrison is designed for efficient use of space. Once you enter the home a well planned collection of spaces conveniently serves your living needs. The living room is open above to the roof with a cathedral ceiling (a great room) and exposed beams. This space receives a significant amount of daylighting all year, and receives seasonally appropriate solar gain in winter with its two story facade of windows facing south. The living room is a room you will use because it is also a practical family room.

The dining area is within the same great room but defined by a lower ceiling. The dining area feels and appears spacious and is easily accessed from the kitchen. The kitchen is easily accessible from the dining area and is clearly defined by an island wall.

Garrison view on June 21 at 11:30 a.m. with south windows in cooling shadow of overhangs. There is a shaded air space between the roof and the solar collectors. This allows for convective cooling of the roof and improved efficiency of the photovoltaics.

Garrison views of the living/great room. Optional water filled copper tanks provide excellent storage of thermal energy since water has a large volumetric thermal capitance. These tanks moderate indoor temperature variation throughout the year. An operable skylight over the stair at the highest part of ceiling allows for natural ventilation in summer.

Garrison view December 21 at 9 a.m., the beginning of solar energy collection. Snow will slide off the glazed solar equipment with sunlight. Note that the form of the house causes winter winds to slip easily up and over the roof, reducing energy loss.
