Renewable energy options including solar shading devices
for windows and doors and photovoltaic (PV) devices must be considered.
Therefore, shading devices
were designed to prevent excessive solar radiation and to distribute daylight evenly into the interior spaces.
Terracotta baguettes and a solar canopy are utilized as exterior shading devices
on 80 percent of the glazing.
The contract also includes all glass panels, windows, doors and structural components of the facade and the roof, including exterior shading devices
and fittings work on facades and roofs.
Windows and shading devices
present many complexities and, for good results, must be represented in precise ways.
Reflective glass and shading devices
were used to minimize direct heat.
If there were no exterior shading devices
, the glazing would have to do more work by being darker or more reflective, or the glazing area would need to be reduced.
However, inappropriate use of shading devices
can result in problems such as increased overall energy use, excessive glare and thermal discomfort, as well as limited view to the outside.
Exterior shading devices
at southern windows and the second floor cantilever provide shade on wall and glass surfaces, which reduces interior heat gain from the sun's daily movement.
For example, an OR at University Hospital Dusseldorf's Centre for Surgical Medicine II (Dusseldorf, Germany) combines exterior and interior shading devices
to control and redirect daylight, while horizontal louvers are integrated into a double-skin facade to block sunlight.
Massing strategies provide large perimeter openings with external shading devices
, a central clerestory and light well through the center of the building, and glazed corridors to the teaching spaces.
He said: "We have orientated the buildings to create natural shade onto external spaces, but where this has not been possible, we have provided external shading devices
and careful placement of landscaping elements to allow the students to circulate through the campus under cover.
