46 BUILDING FABRIC
AN INCREASING COMMITMENT TO SUSTAINABILITY
ur research has shown us that people in various roles think about sustainability in very different ways. n architect, for instance, is very process-driven and concerned about metrics, performance, and ultimately accreditation. Rs most recent ethics sustainability survey conducted in , showed how a commitment to sustainability and low-carbon design had become even more important to its members, and how more homeowners are also thinking about the eco-credentials of their homes and about how to reduce their energy costs.
ypically for interior insulation, we see mineral or wool rolls being used in between wooden battens. With interior wall insulation, the fi nished building will keep a more stable interior climate, there is no impact on the external appearance of the house, its less expensive and its possible to use a wide variety of insulation material. he downsides are a loss of internal space and many types of insulation material reuire a fi re- rated covering.
ome points to consider before making
the fi nal specifi cation are the thermal resistance of the insulation method, the overall insulation gain, how fi reproof and how safe the materials are, the expected lifespan and whether they can be easily recycled. dditionally, whether a property has a warm or cold roof, there are measures that need to be taken to ensure the long-term energy effi ciency of the building. he key for roofers is to ensure that the ventilation in the roof space is well planned and constructed.
Unique solar roof tile launched by Breedon Group collaboration
A
unique solar roof tile has been launched in a collaboration by UK construction materials group Breedon.
Breedon Generon is a premium whole roof
concept comprising a 3.2 mm monocrystalline tempered glass PV cell discreetly integrated with a Breedon Elite 330 mm x 420 mm base concrete roof tile which is laid in sequence with matching standard roof tiles. Interconnecting cables then link the Generon tiles to create an overall solar output based on the number of tiles fi tted. Typically, 260 tiles are required to generate a 4 kW PV system – the benchmark for family homes. Fitted by roofi ng contractors in an almost
identical way to traditional roof tiles, the Generon system then simply connects to
the remaining PV infrastructure to generate safe, reliable and renewable energy. This combination delivers a seamlessly integrated solar roof, without compromising aesthetics – a key attribute specifi cally designed to appeal to architects/specifi ers and homeowners who, when questioned during research, wanted their home to generate solar energy but disliked the appearance of traditional solar panels, or even the more recent integrated solar systems. To develop their innovative solar tile, Breedon
partnered with Terran, a leading European roof tile manufacturer. A third-generation family-owned business, Terran has been at the forefront of roofi ng product innovation since 1920, and over the past fi ve years has successfully developed and distributed the Generon roof tile across Europe. Unlike traditional solar panels, Generon solar
roof tiles off er a sleek and seamless design that blends in with the rest of the roof, whilst delivering high levels of performance. They also eliminate the need for separate contractors to install solar panels and their associated mounting materials as they can be easily installed by a roofi ng contractor using storm clips in sequence with the standard concrete roof tiles, thus reducing the time and overall cost of installation. Generon has been designed and tested to be highly durable and withstand harsh weather

conditions, including heavy rain, hail and high winds. Such solar roof tiles typically have longer lifespans than traditional solar panels and require less maintenance over time, owing to the securely integrated nature of their design. Sleek and smooth in situ, the Generon system
carries a 20-year performance guarantee, and has a dedicated home owner app to track real- time data about its energy production. Breedon Group commercial manager Mark
Morris said: “The Generon system off ers building owners the opportunity to capitalise on the growing renewables market and specifi ers the chance to help their customers to meet Part L of the Building Regulations.” “By investing in Generon, we have committed
to becoming a leader in this new market by delivering the fi rst roof top solar system which delivers cheap renewable energy, whilst maintaining the aesthetic integrity of the house.” Growth forecasts for Generon are therefore
very promising, with many industry analysts predicting double-digit annual growth for the adoption of solar systems for the next decade.

ow manufacturers have to address an increasing number of uestions about sustainability with housebuilders and developers. hey want to know where the materials have come from, if they have a high second use content, and how a facade will improve their carbon footprint. We believe that advancements in sustainable construction will continue at a rapid pace, transforming home design. nd manufacturers can help in the path to sustainability by improving circularity and environmental impact.
