Low Carbon Design: Utilising Flat Roofs to Combat Carbon

2. Green receptivity

A flat roof is significantly more receptive to the installation of green components such as solar panels, green/living roofs and urban agriculture. A flat roof remains flexible for these elements to change and adapt over time. We often see solar panels on new builds, but we can also add them to existing roofs without penetrating the membrane and causing damage. With Nuralite Fixing Plates you can fix solar panels onto any current flat roof.

3. Multi-functional space

A flat roof can be utilised by building occupants for many outdoor activities. From basic outdoor decking, to gardening, hot tubs and bars, rooftop activity is a growing niche that becomes a valuable and functional space for building users. Again, the flat roof is flexible for the life of the building and comes without the impact or cost of using additional planetary surface area.

In the last few years Nuralite have found roof renewals becoming increasingly popular. Overlaying a building's existing roof instead of rebuilding is a way to reduce the amount of carbon attributed to its footprint.

Upgrading the current stock of buildings so they are more fit–for–purpose, instead of demolishing them, is a better option and reduces unnecessary building waste. Nuratherm warm roofs can be retrofitted to existing membrane and metal roofs to extend life and improve building performance.

Carbon usage in building operations has a significant impact on our climate footprint. Upgrading 1,200 commercial buildings to zero-energy would save our entire wind generation capacity. Vital to designing zero energy buildings, warm roofs provide a continuous level of insulation without thermal breaks. These can be used on all properties and are ideal for passive houses.

Architects Declare seek to "Upgrade existing buildings for extended use as a more carbon efficient alternative to demolition and new build whenever there is a viable choice" — and Nuralite agrees.

Nuralite encourages designers to look at options such a Warm Roofs and existing overlays or look to add roof gardens or solar panels to their next project. As suppliers they found themselves in a position to make a difference not only in their own business actions, but in the zero energy building message they promote.

The Emissions Reduction Plan set out by MBIE has come at a crucial time for the building and construction industry and together we can create actionable change.
