Prevent heat loss Air leaks in cracks and openings around windows and doors are prime sources of heat loss. Warm air seeps out through the cracks and is replaced by cold, outdoor air. Caulking should be used wherever two different materials or parts of a house meet at a stationary location. The most common places are around windows, doors, foundation sills, chimneys, water faucets, vents, electrical outlets and pipes. Landscaping for conservation Planting trees, vines and shrubs in the appropriate places can actually reduce temperature fluctuations in your home.
Deciduous trees can help in every season.
In the summer, they block the sun with their leafy limbs. During the winter, they allow the sun to shine through their bare branches, providing warming sunlight. Deciduous trees are best planted on the southern and western sides of your home. In the winter, evergreen shrubs planted on the north and west sides of your home can help block winter winds. Vines are another way to make your landscaping work for you.
