Southern Orientation

Highlights

Southern orientation with properly sized overhangs can save you up to 40% of your heating and cooling costs. Naturally certain lots are more difficult for orientation, but the cost of aligning the angle on paper during the planning phase is marginal relative to making changes after initial construction or for remodeling.

You, your architect, or builder can actually calculate the overhang based on the latitude of where your live to shade all of the summer sun and let all of the winter sun heat your house. As an example 18” works in Philadelphia where the sun is 85% off the horizon in the summer at noon and drops to 25% over the winter.

The ROI Calculation is based on adding design time to 'shift' the plan to a southern orientation for an addition or new home. Expert Architectural/Landscape Site design Services at $120 / Hour for 10 hours.
