Project Description:
This is a house for a couple with two teen age children.The site is a southern sloping open field of an abandoned orchard. The entry is on the north side upper main level, the childrens bedrooms are on the lower walk out level. The upper level includes mud room, kitchen, open living/dining area and the master bedroom and bath. there is a large screened porch adjacent to the ding area. The lower level also includes a bathroom, guest room and utility room.
This is an all electric1800 SF house, heated by a mini-split heat pump for each floor. The domestic hot water is provided by a hest pump water heater. Ventilation is by a Fantech Flex 100 HRV.
The house is powered by an 8.2 kW PV array which was installed in 9/15, it is pmodeled to cover 80% of the electric load.
The construction was tight aceiving .68 ACH50.

Site description:
The site is a south sloping abandoned orchard.
Materials:
This is a wood framed building on a pored concrete foundation. Advanced framing techniques were used, along with state of the art Advantech building products including Zip sheathing as an air barrier. This was a low budget house so there were few upgrades. The products chosen were for longevity and low maintenance. Roofing is Fabral metal roof and PV panels. The siding is Hardie plank lap siding. Windows are Mathews Brothers PVC triple glazed windows fabricated in Maine.
Energy Highlights:
30 Sunmodule panels.
LCA Description:
LCA was not used. Materials used were chosen for long term quality and low maintenance.

Special architectural measures:
This is a solar passive design with southern glazing equal to about 8% of the floor area. The truss roof includes 18" of cellulose insulation. The ceiling plane is the air barrier. The house is a simple volume to reduce the number of corners, making construction easier, less expensive and easier to air seal. The blower door test verified that it has .68 ACH50.
Energy Strategies:
Maximize the solar gain and the tight thermal envelope, then add a PV system to meet the electric load as much as possible.
