To determine your home's orientation, use a compass to identify north, south, east, and west. South-facing windows maximize natural light and heating in temperate climates, while north-facing orientations provide consistent shade. Online tools like or Google Earth’s sun path feature can visualize solar exposure. For accuracy, cross-verify with a digital compass or astronomical apps.

Home orientation significantly impacts energy efficiency and comfort. South-facing windows in the Northern Hemisphere capture more sunlight, reducing heating demands by up to 30% and cooling costs by 15% (U.S. Department of Energy, 2020). Proper alignment also enhances natural ventilation, lowering reliance on mechanical systems. A study by the National Renewable Energy Laboratory found that homes oriented within 30 degrees of true south reduced annual energy use by 7-12% (NREL, 2018). misorientation can increase utility bills by 5-10% annually, as seen in a 2019 study by the International Energy Agency. Strategic placement of windows and shading devices further amplifies savings, making orientation a critical factor in sustainable architecture.
