Lighting the way with rooflights

Rooflights play a vital role in the modern building but are often overlooked. They are the common link to many aspects of building design and can help the designer, the building owner and the occupier to achieve a truly sustainable, energy efficient and enjoyable place to work and to live in. Correct rooflight design at the outset of the building concept can have dramatic efforts on all aspects of the building from the owner’s potential asset value to the well-being and productivity of the occupants.

Buildings which provide high levels of natural light generally have more positive working environments than those which are dependent upon artificial light. It is known that people respond better to working in natural light conditions, as the eye and brain functions work better, resulting in improved concentration and overall performance. Plus, of course less dependency on artificial light significantly reduces energy consumption and running costs as well as impacting positively on the buildings overall carbon footprint.

Thermally efficient insulated rooflights can further reduce heat loss and energy costs. These benefits, and the effectiveness of rooflights as a contributor, are acknowledged in the Building Regulations Approved Document Part L. It recommends that industrial and commercial building structures should have a rooflight area of 10% to 20%.

This graph demonstrates the reduction in CO2 emissions of a typical notional building as the rooflight area is increased to the optimum 16% to 18% and used in conjunction with a fully automated lighting control system.

There are other aspects to be considered within sustainable building design, featured in the diagram above. To find out more about these considerations and their importance when specifying rooflights, please visit our technical guide section in the left menu.

Whatever the principle daylighting design consideration there is a Zenon solution to match.
