1.1.6 Correct use of external solar shading
Description
In cooling seasons users have to block direct solar radiation by closing solar shadings to avoid internal overheating. In others seasons solar shadings should be opened to take advantage of natural light and, in heating seasons also of solar radiation to increase internal thermal load.
Benefits
Shading windows can block up to 90% of heat generated by direct sun.
Reduce internal summer temperatures
Improve comfort
Reduce the use of cooling and heating systems
Limitations
Occupant acceptance
Design defect
Economic assessment
The initial investment is zero, although it is convenient to train and inform properly users on these issues. It reduces the costs associated to HVAC systems.
