How can landscaping affect a home's HERS rating?

Landscaping plays a significant role in a home's energy performance and can indeed impact its HERS rating through various means. One of the key benefits of proper landscaping is its ability to provide shade, which directly influences the cooling load of a home. By strategically planting trees, shrubs, and other vegetation, a homeowner can reduce solar heat gain on the building's exterior during the hotter months.

Shade from trees can keep the home's walls and windows cooler, which can lead to lower air conditioning demands and ultimately less energy consumption. This reduction in energy usage contributes to a better HERS rating, indicating improved energy efficiency. Additionally, landscaping can enhance the microclimate around the home, further promoting energy conservation.

By utilizing landscaping effectively, owners can not only improve their home's energy performance but also increase occupant comfort and potentially decrease utility expenses.
