The Arapahoe Gardens Home is a three bedroom, two bath, one story home consisting of about 1300 SF. The home is located within the urban farm of the community.
The two block site will accommodate row homes, multifamily units and four single family homes. The features of the community include an urban farm of almost 2 acres, a central street in which to hold events and farmers markets, and a parking structure.
To further instill the idea or Urban Farming, the solar homes will have garden options available to the buyer which include:
- Raised Garden Beds
- Fruit-Bearing Trees and Shrubs
- Extra Storage with Double-Wide Door for Wheelbarrows
- Chicken Coops
- Green House
Raised Garden Bed Benefits
- Water conservation
- Higher yields and less area to weed
- Earlier planting
- Maintain a consistent temperature
- Frost protection
- Accessible gardening
The homes are located within the Urban Farm to help create the connection between the individual home and the community. Urban Farming is the idea of growing a product to be sold. Community Garden is more for personal consumption and sharing. The Goal is to shape a community that does both. Grow for profit AND personal consumption.
The Floor Plan
The layout of the Arapahoe Gardens home is inspired by the idea of Frank Lloyd Wright’s Usonian home and the idea that a house could be designed in a democratic, distinctly American style that was affordable for the ‘common people. The Arapahoe Gardens home has three zones, the living/dining space, the master bedroom suite space, and the bedroom/bathroom space.
Heating and Cooling Systems
The home’s heating and cooling system consists of many supporting components. The main component being a horizontal, 10 pitch slinky, closed-loop system. The system is estimated to be a 2-ton system. A horizontal 10 pitch slinky system requires 10ft pipe/ foot of trench and is recommended that the trench length be 115 feet, meaning 1150 feet length of pipe is recommended.
Number of parallel loops and/or trenches is 3-4. 1 heat pump is required for a 2-ton system with 1/12 HP. The house has a system of ductwork in an insulated crawlspace to distribute the hot and cold air throughout the house.
Costs to install a horizontal ground loop alone are about $750/ton. An entire horizontal system (including loop, heat pump, ductwork etc) is about $8,200/ton. The State of Colorado offers a 30% refund for the year of installation. For this system (a 2-ton system) the costs estimated are a total of $11,480 ($16,400 minus the 30% refund of $4,920).
In addition to the geothermal, the house’s windows are placed towards the roof with overhangs. This allows daylight to enter the house during the winter months and heat the house through direct solar gain. The overhangs on the roof prevent that same sunlight from entering the house during the summer months, helping to reduce the heat gained throughout the day.
