It is not generally suitable as a kitchen as the heat from dinner preparation coincides with low-angled afternoon and evening sun, potentially causing glare and overheating. provide good direct solar gain for thermal mass heating of living spaces in the evening.Ī west-facing orientation is suitable as a living area in households where occupants are away from home during the day-time but at home in the evenings.may require vertical shading to prevent excessive overheating and glare in the afternoon.can overheat in the late afternoon for much of the year.West-facing roomsĪs west-facing rooms get low-angle, late afternoon sun, they usually require some shading to prevent overheating and excessive glare, particularly during the summer. Early risers generally appreciate east sun in spaces they will use first thing in the morning such as breakfast bars. have solar gain in the morning throughout the year to provide initial warmingīedrooms that face east will be cooler in the late afternoon and evening, making them more comfortable for summer sleeping.

OPTIMAL LAYOUT WINDOWX WINDOWS
In general, north-facing windows should be efficient at letting solar radiation into the building (see glazing and glazing units for more). This page provides more detail on ideal solar orientation for different types of room.Īs discussed in location, orientation and layout, solar orientation will have to be considered alongside other factors such as noise, views, privacy, and passive cooling features such as ventilation and shading.įor solar gain, it is also important to consider the thermal performance and solar heat gain efficiency of the glazing unit itself. We also explained that rooms should be located to take best advantage of the sun – for example, by having living areas face north where they will receive all-day sun and service areas face south where they will receive little sun. In location, orientation and layout, we explained how building orientation can be used for passive heating and cooling. Orient rooms to take advantage of the sun when it’s wanted, but avoid overheating and glare.
