Colt experts are able to work with the architect, providing calculations and modelling to ensure the proposed solution offers the best performance while making a strong architectural statement.
Sun shading, directing daylight and energy saving - the function of fixed and controllable solar shading systems
Buildings with large areas of glazing make the best use of natural daylight and passive solar heat. But there can be too much of a good thing: too much daylight in the wrong places can lead to glare, and too much sun can lead to overheating.
Colt's sun shading systems eliminate excessive glare and reduce solar heat gains in the summer. During the hotter months of the year, the building is protected against overheating by Colt's adjustable heat reflecting sun louvers, which are oriented according to the position of the sun. Radiation from the sun is partially absorbed and reflected by the solar shading louvers, which reduces heat gains within the building.
Modern glazed buildings frequently use more energy for cooling in summer than for heating in winter. The use of external solar shading systems can enable the cooling loads to be greatly reduced or eliminated.
In the winter months, the situation is reversed, as buildings lose heat through their glazing. Colt's sun shading louvers can be positioned so as to reduce heat loss as well as to help capture any heat coming from the winter sun.
The quality of daylight changes continuously within a building, depending on the time of day, the weather and the season. Colt's sun protection louvers can be oriented to enhance the levels of natural light while minimising glare, providing ideal natural light quality in the building throughout the daylight hours all year round, and reducing as much as possible the need for artificial lighting. This can be achieved by the use of transparent or translucent shading louvers, which provide good light quality even when closed.
