Consideration when planning energy efficient landscape

These are some questions to consider when planning for an energy efficient landscape:

1. What is the sun's path over your site in relation to nearby ridges, tree lines, or structures during the summer and the winter?
2. What are the prevailing wind directions for winter storms, as well as for summer day-night breezes?
3. What is the orientation of the view you wish to let in?
4. What is the orientation of developed areas around the site that might require screening at or away from the house?
