Reducing environmental impact of services supported on flat roofs

Flat roofing can achieve sustainable built environment with maximum internal space with a roof that provides opportunities for the installation of green roof and the housing of building services including micro renewable such as solar voltaic panels. The roof system designed plays a significant role in managing energy use in the building through limiting heat loss.

* eliminate design details that create thermal bridging.
* thermal insulation on the roof is continuous.
* reduce waste and material used. (less concrete and steel)
* designed for future flexibility - future uses and maintenance issues.

Roof-Pro support systems are a modern method of off site fabrications construction that fit with Approved Document Part L2A. By supporting services on Roof-Pro Systems the demand for carbon intensive materials such as concrete and steel is reduced. Casting a slab of concrete for a chiller 2.m x 3m x 0.300m requires 1.8m3 (3,960kg at 2.2T/m3) of concrete. A chiller of that size could be supported on Roof-Pro Systems, where the steel used is small section 50x50 RHS + 76 x 38 RSC (approximate mass 70kg). The cost (environmental and financial) does not stop there. Part load of concrete, concrete pump, shuttering formwork, any steel, labour, co-ordination of new trades at roof-top you can keep adding to this list.

Reasonable provision shall be made for the conservation of fuel and power in buildings by limiting heat gains and losses:

a1. Through thermal elements and other parts of the building fabric. Roof-Pro systems no cold bridging.

4a. Where a person intends to renovate a thermal element, such work shall be carried out as is necessary to ensure that the building complies with the applicable requirements of Part L of schedule 1. Services supported on Roof-Pro systems facilitates re-roofing and enables upgrade of insulation.
