How landscape design can help save energy Landscaping is an easy and inexpensive way to improve the energy efficiency of a building, enhance the appearance and value of a property, and provide screening for privacy. Selected types of plants can be strategically positioned to protect the building from the harsh extremes of summer sun and chilling winter winds, improve comfort both inside and outside the home, and reduce the need for supplementary heating and cooling. Deciduous trees and vines can be 'designed' to shade exposed indoor and outdoor living areas in summer while still allowing the sun through in winter. Low shrubs and ground cover around the home can reduce reflected heat and glare. Dense trees and shrubs can be positioned to deflect strong winds and channel cooling summer breezes.
