Landscaping is an easy and inexpensive way to improve the energy efficiency of the building 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 healing and cooling. Shade from trees to roofs and/or windows can reduce indoor temperatures by 6-12 ‘C in summer. Conversely,ensuring winter sun penetration through windows can save substantial amount of heating energy. External temperatures can be reduced up to 6’C by using ground cover or lawn instead paving. These temperature differentials improve both comfort and energy efficiency of the home so that heating and cooling requirements are reduced. The principles are shown in the presentation attached.
