Objectives: |
- Evaluate the energy use, installed costs, and comfort of radiant floor heating systems compared to conventional forced-air heating system.
- Evaluate the installed cost, energy use, volume of ventilation, and CO2 levels within the home by using a ventilation system controlled by CO2 levels in the home.
|
|
General Construction Information: |
2,750-square foot, single-family home; 2x6 wood-framed walls and double-pane vinyl windows (19 percent of exterior wall area); ventilated crawlspace foundation and asphalt shingle roof; radiant and gas forced-air heating; no central cooling system. |
|
Significant Results: |
- Radiant floor heating system used almost identical amount of energy as forced air heating system at same temperature set-point.
- Ventilation system controlled by CO2 levels in the home produced acceptable CO2 levels for significantly less energy than would have been used by a ventilation system meeting ASHRAE 62.2-2003 requirements.
