Main house 16' x 24', bedroom wing 12'x 20' (total 904 square feet) - 2 bedrooms, 1 bathroom
First floor is 624 square feet and second floor is 280 square feet. The screened porch is 112 square feet, not included in the total area above.

This Solar Bungalow has its main entrance on the north porch. A coat closet and utility with stacked washer/dryer are adjacent to the entrance. A common space on the first floor provides a living family area, dining, kitchen, and access to the hall, stair, bathroom, and master bedroom with walk-in closet. The screened porch is an option and is accessible from the living space. There is a sleeping loft and study on the second floor accessed by an L-shaped stair. This is a compact Bungalow, suitable for a couple, young or old, and makes a great starter home with beds for up to two children on the second floor. It also can serve the needs for the elderly in their retirement years when they want to down-size, live with less to maintain, and have an occasional guest stay over. All needs for a couple living on one floor are accomodated.

This design is compact, makes efficient use of space, and can be very economical to build. This Bungalow is designed with passive and active solar systems which allow for reduction of non-renewable energy needs, making it possible to achieve net zero energy usage. While this design is small, it makes good use of available space with generous glazing and a high ceiling over a portion of the living and dining area to provide a feeling of spaciousness.

View of west and south elevations. The screened porch is optional. The south facade is glazed with operable doors and windows to allow passive solar gain in winter and ventilation in summer. The south roof has a large opening with operable shades to provide control of incoming solar energy (see detailed explanation below).

The common area of the first floor is 12' x 22' 8" and it has an opening to a cathedral ceiling above. It also has a generous amount of glazed doors and windows, particularly to the south for passive solar gain in winter. Also, doors lead to the screened porch and can remain open for a good part of the year for natural ventilation. The kitchen is equipped with a stove, microwave, refrigerator/freezer, dishwasher, sink, and sufficient cabinetry to accommodate a family of four. A window at the sink faces east for morning light and a view to the drive. A hall leads to the stair, common bathroom, and door to the master bedroom. The living and dining area occupy the heart of the common space. A wood stove is located in the southwest corner.

Active/passive solar features

The roof of the Solar Bungalow supports passive and active solar. The active solar includes thermal and photovoltaic panels. The passive component is the large opening in the roof which allows direct gain through windows when desired and is owner controlled.

View of the south elevation with a 4.2 kWh photovoltaic array made up of 20 photovoltaic panels for the production of electricity and two thermal collectors for the production of solar heated water for domestic use. Two operable shade clothes are shown partially deployed. The top shade blocks 90% of the light, the second shade blocks 40% of the light. They are motorized and operated to suit the season in general and the day specifically if desired. Spring and Fall usually require more adjustment.
