Abstract
In this study, HEED program designs Scheme 2 it automatically selects one good set of Energy Efficient Strategies for the case study climate, building type and square footage. Certainly there are other combinations of strategies that could prove more efficient. As we copy it to other schemes we might wish to try other strategies from the list below. A list of the best strategies for our particular climate is on the Energy Efficient Design screen. In general they include:
-Direct Gain: In cold climates, add large south windows and internal mass.
- Minimize West Windows: In hot climates west windows add huge heat gain.
- Super Inslation: In cold climates, add two or three times minimum insulation.
- Movable Night Window Insulation: In cold climates, drapes can automatically close at night (see Advanced Windows).
- Skylights: Electric lighting can be reduced by skylights on 3%-4.5% of roof.
- Low Thermal Mass: Try low-mass walls and floors in cold- overcast or hot-humid climates.
- High Thermal Mass: Add high-mass floors and walls in hot-dry climates or cold-clear climates with large south windows.
- High Mass With Night Flushing: In high mass homes in hot- dry climates, high air changes at night will store ’coolth’ for the next day (natural ventilation or fan).
- Whole-House Fan: HEED’s smart thermostat can turn off a fan for free economizer cooling.
- Night Setback Thermostat: Automatically setting cooler night temperatures saves fuel especially in cold climates (it is also required by Code).
- Thermostat Deadband: Set the widest difference between indoor comfort high and low temperatures to safe energy.
- High Efficiency Air Conditioner: Install one with the highest SEER (12 or 13).
- High Efficiency Furnace: Install one with the highest AFUE .
- High Performance Glazing: Low-E coated, multi-pane glass is more cost effective in the very hot and cold climates.
- Weathers Tripping: This kind of infiltration control saves energy and
- Daylighting: Electric lighting energy can be reduced by natural light from large well placed windows with clear glass and narrow floorplans, see Daylighting screen and plot kWh Lights.
- Exterior Window Shading: In hot climates, provide correctly sized overhangs on all south windows, and on east and west provide overhangs and fins.
- Fluorescent Lighting: Can reduce power density by a factor of four (see Daylighting).
- Cool Roof: Very light colored roof with high emissivity can reduce heat gain in hot climates.
- Radiant Barrier: A reflective metallic surface usually applied to the underside of the roof surface where it faces into the attic space or into a dead air space in a flat ceiling assembly.
