Roof glazing helps to bring natural light deeper into a building, and can help to achieve an even distribution of daylight. Getting the right balance between reducing reliance on artificial lighting (thereby saving energy), utilising solar gains and minimising heat loss due to excessive glazing is a critical part of daylight modelling and assessing building fabric performance.
What BREEAM credits can be claimed through using modular skylights?
There are some twelve different areas in which VELUX Modular Skylights can help obtain BREEAM credits within New Construction, Non-Domestic Buildings Standard.
The positive impact of daylight on building occupants is recognised in the health and wellbeing category HEA01, which includes a credit for visual comfort. It requires that 80% of the occupied space meets a minimum daylight factor of 2% - or, for Excellent level, 3%.
Glare control and views to the outside - factors which are covered by the EN 17037 daylighting standard - also contribute towards earning credits. VELUX Factory-fitted roller blinds or VELUX opal glazing can form part of a building management strategy.
What is the environmental impact of modular skylights?
BREEAM credits can be earned for the management of indoor air quality, including using finishes and fittings which emit low levels of Volatile Organic Compounds (VOCs). The long-term health effects resulting from exposure to VOCs is increasingly being recognised, so all VELUX Modular Skylights have been tested to VOC benchmarks and achieve the maximum A+ rating. Our VOC report is available on request.
VELUX Modular Skylights are available as venting modules, which can assist in managing air quality and ventilation and can be controlled automatically via VELUX INTEGRA ® or a building management solution.
The environmental impact and responsible sourcing of materials is assessed in BREEAM through the use of Environmental Product Declarations (EPDs), produced in accordance with EN 15804. We have published more information on environmental impact, including VELUX Environmental Product Assessments (VEPA), to assist with specification decisions. VELUX Modular Skylights EPD certificates are available for double and triple glazed products.
How do modular skylights contribute to a fabric first approach?
VELUX Modular Skylights are available as double or triple glazed units, with further specification options to help manage the U-value and g values of the system. Each module comes with built-in provision to tackle condensation in the unlikely scenario of moisture accumulation, while use of ventilating modules give control over natural ventilation to manage heat retention or cooling.
