15 sty 2021 · West-facing windows have higher impacts due to the larger energy needs. In warm climates, low solar factor contributes significantly to reduce impacts. Window thermal transmittance is key to reduce impacts in cold climates.
1 kwi 2023 · The cooling effect and heat flux distribution of a west-facing two-storey building covered with thick ivy has been investigated experimentally. The peak cooling load of ivy coated green building wall has been reduced by 28% [114].
Additionally, east and west facing windows cannot be effectively shaded during warm seasons when solar heat gain is unwanted; solar heat gain through east and west windows during warm seasons may require more energy to offset those gains with air conditioning.
The biggest problems with solar heat gain and the glare which direct sun entry can produce are experienced with east- and west-facing windows. In the middle of the morning and afternoon the sun can be low enough in the sky that only a very wide overhang can be effective.
1 paź 2021 · For example, in a hot climate, north-facing windows have the least impact on energy usage compared with south-, west-, and east-facing windows when no overhang was employed. However, the difference became negligible when the solar heat gain coefficient of windows was substantially decreased.
1 sty 2018 · East- and west- facing windows gain far more heat than south-facing windows during the summer months, until late August. West-facing windows gain that heat in the afternoon, usually during the hottest time of the day, making west-facing windows particularly undesirable unless well shaded.
Building orientation influences passive solar heating by maximizing the exposure to sunlight during colder months. Proper orientation typically involves positioning the building with large windows facing south in the Northern Hemisphere, allowing for optimal heat gain while minimizing heat loss.
