Energy + Performance

Place and shade windows for the room’s use. More glass alone doesn’t create better daylight.
Good daylight comes from the position and design of openings, not simply from adding more glass. Plan windows with the home’s orientation, shade, views, privacy and room use in mind. A beautiful window can be uncomfortable if it puts direct glare on the place where you work or relax.
Begin with the light you want in each room at the time you normally use it.
Mark where the sun reaches the property and what nearby buildings or trees shade. Discuss morning and afternoon exposure with the design team. Then place furniture, screens and work surfaces on the plan so the light can be evaluated in context.
A view may deserve a large opening. Another wall may work better with higher or more selective windows that bring in light while preserving privacy and usable wall space.
Porches, overhangs and other shading features should be considered while the exterior is designed. Their usefulness depends on orientation and geometry. A deep roof does not provide the same protection from every sun angle.
Interior shades remain useful for glare and privacy. Plan space, power and access for them if needed, rather than treating them as an afterthought once the windows are installed.
Window performance includes more than appearance or pane count. Ask the team to explain the selected product’s U-factor, solar heat gain coefficient and visible transmittance in relation to the room and climate. These describe different things: heat transfer, admitted solar heat and visible light. The Department of Energy’s window guidance is a useful starting point.
The product and the installation both matter. Flashing, air sealing and the connection to the surrounding wall need to be coordinated.
Walk through the plan looking for spaces that may feel dark beside a bright room, places where afternoon glare could be difficult and views that expose private areas. Use the review to adjust the plan before ordering windows.
We want the home to feel good to live in throughout the day. That may mean more glass in one location and a more controlled opening in another. Read how the home’s systems work together.
