Glazing Strategy: Windows that Work Hard
South, East, West: Different Glass for Different Sides
Use higher solar heat gain coefficient glass on south windows for winter warmth, and lower SHGC on east and west to tame summer spikes. Pair with careful shading. Tell us your climate zone, and we’ll suggest a starting SHGC and U‑factor range.
Sizing Overhangs with Simple Geometry
Overhangs can invite low winter sun while blocking high summer rays. Start with your noon solar altitude angles for solstices and equinoxes, then set depth and height. Measure your current eaves, post dimensions here, and we’ll help sanity‑check the geometry.
Tight Installation, Warm Edges, and Airtight Frames
Even great glass fails without airtight installation. Specify continuous gaskets, backer rod, and sealant, plus warm‑edge spacers. Inspect for shims and insulation around frames. A careful afternoon with a smoke pencil often reveals leaks you can fix before the first freeze.
Thermal Mass: Store the Day, Release at Night
Polished concrete slabs, dense masonry, or even water features can bank heat. The key is exposure: place mass in direct winter sun paths. Map sun patches on your floor for the solstices, and ensure furniture won’t block the warming light.
Too much glass without enough mass can cause afternoon spikes. Target a design that keeps daily temperature swings modest, then verify with a simple energy model. Share your south window area and floor material; we’ll help decide whether you need more mass or shading.
In a renovation near Santa Fe, a sunlit slab warmed quietly all day. At dusk, while neighbors reached for thermostats, their living room held steady comfort. They called it their silent heater and said sunsets felt like the home exhaled warmth.
Shading and Seasonal Controls
Leafy trees protect east and west facades in summer and open to light in winter. Pergolas with adjustable slats can fine‑tune shade patterns. Post a photo of your yard orientation, and we’ll brainstorm plantings that perform without blocking winter rays.
Shading and Seasonal Controls
Exterior blinds and interior cellular shades reduce heat gain and nighttime losses. Automated schedules help, but even mindful routines work wonders. Try closing night insulation after sunset this week, track room temperatures, and share your results with our community.
Daylighting: Bright Rooms, Low Energy, Happy Eyes
A light shelf reflects sun up to the ceiling, diffusing brightness across the room. Higher ceilings amplify the effect. Try a cardboard mockup on a sunny weekend and post photos—small tweaks here can transform gloomy corners into cheerful spaces.
