Carbon reduction targets and solar PV

With the Future Homes Standard still three years away, the immediate focus for the housing sector is the imminent introduction of changes to Part L of the Building Regulations in June this year.

Specifiers will be looking for the simplest and most cost-effective way to meet the carbon reduction obligations that are fast approaching. And this is where the specification of renewable technology such as effective solar PV on roofscapes can play a central role in helping the sector meet the ambitious targets, set out by government.

The government changes call for a 31% reduction in carbon emissions and all new build homes will need to incorporate low carbon technology solutions – either solar PV, a heat pump or both – to achieve it.

The anticipated emission reduction impact of solar PV prompted trade association Solar Energy UK to predict that upcoming Part L changes will lead to a five-fold increase in the number of new homes built with solar PV.

In the short term, a solar PV system on the roofscape, combined with an efficient gas boiler, appears to be the quickest and easiest way for housebuilders to meet the impending Part L changes.

Seamless aesthetics

Whilst specifiers may have concerns about the appearance of bulky, on-roof solar panels, the latest integrated PV solutions offer a more visually appealing, cost effective, and easier to install option. Integrated solutions replace a section of roof tiles, providing a sleek aesthetic and acting as a seamless part of the overall roof which is installed at the same time as the roof tiles.

To aid the housing sector to make the most of the potential offered by solar PV, and to better understand the benefits of the technology and how best to utilise it, Marley has developed a RIBA-accredited Sustainability and Solar PV CPD, which outlines the different solar options and examines the benefits of integrated versus traditional options.

It also provides important advice on the key considerations when specifying a solar system, from aesthetics, planning and energy requirements, to design and installation. To sign up, just visit
