Hundredfold Farm Cohousing Community

"a place to grow"

Hundredfold Farm Cohousing, Gettysburg, Pennsylvania

Housing

Since its inception Hundredfold Farm members have reviewed many types and approaches to housing.  Some of the criteria used in our reviews included:

Affordability

Energy efficiency

Attractiveness

Quality of construction

Ecological footprint

Appropriateness in a clustered setting

Opportunity for owner finishing

Suitable for hillside construction

Suitable for solar applications

Cohousing suitable floor plans

Two of the cornerstone elements of the Hundredfold vision are Paring, reducing our ecological footprint; and Sharing, reducing our material needs by sharing resources.  With these ideas in mind, it was decided that houses at Hundredfold Farm should have no more than 2,000 square feet of floor space.  Most families will find that with an efficient design, 2,000 square feet will more than meet their needs.  Additionally, by keeping our houses smaller, members will be more apt to make use of community resources, pay less for their houses, have more time for community, as well as assuring that the homes will remain attractive and affordable to those who will someday succeed the existing owner.

The membership determined that the following housing designs best support our goals and vision, as well as being best suited for our site:

Passive Solar Design with Grid Interactive PV System

  • Solar Domestic Hot Water
  • Modular Construction
  • Earth Berming
  • Radiant Floor Heating
  • High Efficiency Natural Boilers

What is a grid interactive PV system?

Included in the purchase price of a HFF home is the installation of a grid interactive photovoltaic (PV) system. 

When the house is delivered to the site, solar electric panels are installed. These panels are wired to a component cabinet located inside the home. A metal cabinet, about the size of a four-drawer bedroom dresser, contains storage batteries, an inverter that converts the solar panels’ direct current (DC) to household alternating current (AC), and a computer controller that continually monitors energy needs. 

The house will also be attached to the local utilities’ electric lines. Throughout the day the computer controller monitors the house’s energy consumption and generation. 

If the solar panels are generating more electricity than the home needs, the excess is routed back though the utility distribution lines lowering your energy bill. 

When the house doesn't generate enough electricity, the computer controller pulls electricity from the utility grid to supplement demand.

If there is a blackout, the storage batteries will provide up to three days of backup for critical equipment. 

The system is completely automated, and requires little to no oversight.
