Building orientation

Building orientation

Proper building orientation can have an impact on heating, lighting, and cooling costs. By maximizing southern exposure, for example, you can take optimal advantage of the sun for daylight and passive solar heating. Cooling costs can be lowered by minimizing western exposures, where it is most difficult to provide shade from the sun.

The one that was selected takes into consideration the choice of the building orientation that allows to maximise the view for the units by creating proper bay width that allows for a wide spectacular view.
The site, building orientation, occupant wellbeing and the type of glass used are all critical components of daylighting design that should be weighted together.
With a blank site to work with, the design team sought to maximize the passive strategy energy impacts related to building orientation, shape and glazing holistically to find the best overall balance that minimized envelope loads while maximizing daylighting and natural ventilation.
In terms of lighting, building orientation and landscaping on the west side of the rink were carefully considered to maximise natural light for normal usage.
In addition, the building orientation was set considering wind currents to better ventilate spaces.
Mrad adds, "I approach sustainability in two ways, by choosing the building orientation and the building skin carefully.
The Power & Financial Model estimator takes into consideration building geographic location, solar radiation for flat-plate collectors (SolarWindow irradiance is derated to account for 360 degree building orientation and vertical installation), climate zone energy use and generalized skyscraper building characteristics when estimating PV power and energy production, and carbon dioxide equivalents.
Solar design features include optimal building orientation, 30 percent overall glazing, and exterior shading devices, used to increase daylight while reducing energy loads.
In that context, building orientation [the way a building is situated on a site and position of its windows, roof lines and other features] is the single most important factor, he said.
Glazing is controlled depending on building orientation, the depth of the window from the facade plane is calculated to reduce direct heat gain, and air conditioning is located in a raised floor to ensure less load than a typical ceiling designed system.
In some cases, proper building orientation alone can already provide energy savings for homes.
