To make your home more energy efficient:
- Stop the air infiltration by sealing the holes and cracks (except for the amount needed to get air to burn gas in the furnace and hot water heater).
- Insulate the ceilings, walls, and maybe the foundation or basement.
- Orientation: have south facing windows with eaves that shade them in the summer. And with the main roof beam going east-west, you can have photovoltaic panels and hot air or water on the roof, plus a trombe wall or greenhouse on the south side.
- Have fresh air from a heat exchanger, heat recovery ventilator, or a moisture and heat recovery ventilator.
- Use local heat such as a hot water bottle, hot tea, hot chocolate, coffee, an electric blanket, a space heater, a sweater, hat, or walk, bike, and exercise to stay warm.
- Put clear plastic over the windows. 3M has plastic that you tape over a window.
- In hot times, you can drink a lot of fluids, wear clothes that provide shade, increase air flow at night through the house via opening windows, fans, exhaust fans, etc.
- Plant deciduous tress and install shades, eaves, or awnings for shade.
