In a first for UK roofing, Edgemere 2.0 combines Marley’s familiar concrete roof tile specification with carbon-capture cement technology and Carbon Bank evidence supplied for every order.

The carbon reduction story behind Edgemere 2.0* begins with the cement. CO₂ from cement production is captured at source, before it enters the atmosphere, and permanently stored beneath the seabed. The carbon reduction is then recorded in the publicly available Carbon Bank, which allocates captured and stored CO₂ reductions to specific Edgemere 2.0 orders, with full end-to-end traceability through an Environmental Attribute Certificate (EAC).

The launch responds to a market in which embodied-carbon evidence is moving from optional to expected. For the public sector and increasingly housing providers, product-level carbon evidence is becoming part of the specification process.

Sustainability leads, along with quantity surveyors and architects, are frequently asked to produce verifiable, product-level carbon evidence and do so without redrawing details or rewriting specifications.

Edgemere 2.0 expands the Edgemere range by offering a low carbon option with a Global Warming Potential (GWP Fossil) of just 1.86kg CO2e per m² from cradle to gate, whilst retaining the familiar thin leading edge, technical performance and dimensions of Edgemere together with a Green Guide A+ rating and BES 6001 Excellent certification.

The change is behind the tile: in the and the addition of verified, order-specific documentation. The Carbon Bank allocates reductions from actual captured and stored CO₂, to specific Edgemere 2.0 orders, with ownership of the EAC transferring to the final customer.

“Edgemere 2.0 is a significant step forward for Marley and for the roofing industry,” said Stuart Nicholson, Managing Director at Marley. “By introducing the UK’s first concrete roof tile to use carbon-capture cement technology, we’re supporting the industry’s transition to lower-carbon construction, with a documented carbon-evidence trail supplied for every Edgemere 2.0 order.”

Edgemere 2.0 is available in Smooth Grey. For more information, or to discuss your next project with one of our specification experts, visit www.marley.co.uk/Edgemere2

About the carbon evidence and end-to-end traceability

*Edgemere 2.0 is supported by Heidelberg Materials’ evoZero® carbon captured near-zero cement, enabled through the first carbon capture facility at its cement works in Brevik, Norway. To avoid the transport emissions that would be incurred by shipping from Brevik, Edgemere 2.0 CO₂ reduction can be transferred and attributed to locally sourced Heidelberg Materials cement.

A Carbon Bank withdrawal is made to reduce the corresponding Global Warming Potential (GWP Fossil) of the locally produced UK cement to zero.  The carbon reduction is recorded in Heidelberg Materials’ publicly available Carbon Bank, which allocates captured and stored CO₂ reductions to each specific Edgemere 2.0 order, with full end-to-end traceability through an Environmental Attribute Certificate (EAC).

CS LOUVRES ARE A CLASS APART AT NEW UNIVERSITY CAMPUS

The University of Northampton’s stunning new £330 million Waterside Campus is set to be a template for sustainability having been built to low carbon, BREEAM Excellent-rated construction standards. Central to the natural ventilation strategy, Construction Specialties’ (CS) architectural louvres will provide excellent airflow and long-lasting protection from wind-driven rain.

EnergyCentre-1-lrEnergy Centre

EnergyCentre-8-lrAs part of the Energy Centre’s natural ventilation strategy, CS’ RSH-5700 rain defence louvres fitted with bird screens were installed at the ground floor level of the South and East elevations forming an air intake area and at the upper mezzanine level of the West elevation which serves as an air exhaust area. The LA-600C acoustic louvres were specified to be fitted behind RSH-5700 louvres in both locations to help achieve noise emission limits stipulated in BREEAM and local planning authority requirements.

Fabricated and delivered to site as modules for efficient installation, RSH-5700 louves were powder coated in RAL 7016 Anthracite Grey, in keeping with the colour of surrounding cladding.

LearningHub-1-lrLearning Hub

LearningHub-4CS louvres were also specified for the campus’s Learning Hub. Fitted to two opposite sides of the building’s 5th floor rooftop plant room, they provide air intake and exhaust functions. On this building, the preference was for a louvre model with vertical blade orientation that blended with the overall building design. RSV-5700 rain defence louvres powdercoated in RAL 9018 Papyrus White, complete with bird guards or blanked off with single skin blanking panels in non-active areas, were installed flush with the polycarbonate walling system.

Solution

Featuring a complex, extruded aluminium blade profile with multiple draining channels, RSH-5700 and its vertical blade version RSV-5700 are high-performance louvre systems designed to provide maximum defence against water penetration whilst maintaining good airflow characteristics. Both systems have been third party tested to EN 13030 standard and achieved Class A rain defence up to 3.0m/s and Class A up to 3.5m/s respectively.

With a class 3 ‘good’ airflow rating, the two louvre models allow the passage of air, whilst providing the area beyond the boiler and plant equipment on both the Energy Centre and Learning Hub with highly efficient protection from rain penetration.
