Orient Your Home to the Sun

Finding True South, Simply

Stand a stick upright at local solar noon and mark the shortest shadow; that line points true north–south. Phone compasses can mislead without calibration, so cross-check with a solar calculator. Share your method in the comments so new readers can try it this weekend.

Window Area That Works

A practical starting point for cold and mixed climates is allocating a modest percentage of floor area to south-facing glass, while keeping east and west windows smaller. This balances winter heating gains against summer control. Tell us your climate zone and we’ll suggest a right-sized range.

A Winter Morning You Can Feel

In one reader’s cottage, a south-facing breakfast nook lifts from chilly to cozy by 9 a.m., warming mugs and moods without tugging the thermostat. If you have a similar sunlit corner, post a photo and subscribe for more orientation tricks tailored to real homes like yours.

Shade for Summer, Comfort Year‑Round

Size overhangs using your latitude’s summer and winter sun heights so winter light reaches deep while summer sun skims the exterior. A quick sketch with window height, sill depth, and sun angles will guide dimensions. Post your latitude, and we’ll help sanity-check your overhang plan.

Daylighting That Delights, Not Glares

A light shelf reflects high-angle sun onto the ceiling, pushing brightness deeper into the room while shading the lower glass. The result is even, comfortable light that reduces artificial lighting needs. Considering one? Share room dimensions, and we’ll brainstorm proportions together.

Daylighting That Delights, Not Glares

High windows admit sky light while protecting privacy, and modest, well-insulated skylights can brighten cores. Manage heat with shades and careful placement, aiming for diffuse rather than direct beams. Show us your layout sketch, and subscribers will weigh in with glare-smart ideas.

Cool Evenings with Natural Ventilation

Open low inlets and high clerestory or stairwell windows to promote rising warm air and draw in cooler night air. The taller the path, the stronger the flow. Tell us your home’s vertical height, and we’ll help plan a gentle, effective night-breeze routine.

Cool Evenings with Natural Ventilation

Place operable windows on opposing walls, keep interior paths open, and use insect screens that favor airflow. Even small, well-aligned openings can change comfort dramatically. Share a floor plan snippet, and our community will suggest tweaks for smoother summer breezes.

Plan, Model, and Budget Smart

Estimate solar gains by multiplying window area, solar heat gain coefficient, and winter sun input, then compare against envelope losses. This quick check exposes imbalances before they become expensive mistakes. Share your rough numbers, and we’ll help refine the math together.

Plan, Model, and Budget Smart

Explore climate charts, sun path apps, and beginner-friendly modeling platforms to visualize angles, shadows, and seasonal performance. Start simple, validate with real weather data, and iterate. Post your tool picks, and we’ll compile a subscriber guide with best‑practice workflows.
