Overhead doors and BREEAM certifications
BREEAM measures sustainable value in a number of different categories - from energy to ecology. Each category focuses on the most influential factors, including low impact design and carbon emissions reduction, design durability and resilience, adaption to climate change, and ecological value and biodiversity protection. Overhead doors can contribute to obtaining several of these BREEAM credits, and we describe them below.
Management category
Man 8 – Safety
The right burglar-resistant overhead door can contribute to BREEAM credit Man 8. This credit requires compliance with the safety adviser’s report in terms of the requirements for the outer shell of a building. More information on burglar resistance can be found in the section on Security.
Energy category
Ene 6 – Minimisation of air infiltration for loading platforms and unloading platforms
An overhead door is often used in a dock environment, where loading and unloading platforms are located. According to BREEAM credit Ene 6, air infiltration around loading and unloading platforms must be minimized.
This applies both when the door is closed and during loading and unloading. Specifically, this means that the door must have a minimum U-value of 0.6 W/(m²·K) on the installed door. The closing speed must also be a maximum of five seconds, i.e. from fully open to fully closed. If the door’s closing speed exceeds five seconds, inflatable shelters may be a good solution. Because they inflate around the docked vehicle, these dock shelters provide significantly better sealing and insulation.
Ene 26 – Building shell thermal quality assurance
The BREEAM Ene 26 credit relates to the air permeability measurement carried out in accordance with NEN-EN 13829 and/or NEN-EN ISO 9972. To meet this credit requirement, overhead doors can be installed in front of the dock levelers in a dock environment. A dock leveler in such an environment is often the largest thermal bridge and the weakest point when it comes to heat flows.
By installing a fast-closing or additional insulated overhead door in front of the dock leveler, the thermal quality of the building shell can be increased.
Materials category
Mat 5 – The substantiated origin of materials
The BREEAM Mat 5 credit sets different requirements for the origin of the materials used. ASSA ABLOY Entrance Systems also feels it is important to know exactly where our products originate and how they are assembled. Our overhead doors are manufactured in a factory that meets the requirements of the ISO14001 certificate, a copy of which is available if required.
