Twin-Therm® Roof And Wall Cladding & Solarwall® Transpired Solar Collector
CA Building Products have contributed in making Armstrong Point the first zero-energy cost business park in the UK. Nine high specification units were clad in CA Building Products’ TwinTherm® roof and wall systems, which contributed to the units achieving air-tightness figures of less than the challenging 3m3/hr/ m2@50Pa which the developer had set for the main contractor, Tolent Construction. The Client will benefit from a full Twin-Therm® 25 year system guarantee, covering the manufacture and design of the roof and wall cladding systems including all of the components supplied and manufactured by CA Building Products such as, profiled sheets, flashings, gutters, fasteners,
sealants, insulation, spacers, etc. This project incorporated the full Confidex Guarantee. Armstrong Developments have confirmed that the units will achieve A+ Zero rated Energy Performance Certification along with a BREEAM ‘Outstanding’ rating for the complete site, the highest accolade available, shared only with a handful of buildings across the UK. This has been achieved by incorporating a number of renewable energy technologies, including a wind turbine, photovoltaic panels, solar water heating and air source heat pumps, together with CA Building Products’ SolarWall® Transpired Solar Collector. The SolarWall® Transpired Solar Collector is an open-loop, active,
ambient air-heating solar collector, which harnesses the sun’s energy to heat fresh, outdoor air for buildings. With no moving parts, the SolarWall® collector provides a truly renewable heat source with solar collection efficiencies as high as 80%. The system offers one of the fastest returns on investments of any solar technology currently available, delivering proven payback periods as low as 3 years. Installed as an additional skin to the buildings southerly facing elevations, the SolarWall® collectors are used to pre-heat the delivery air to the main Nordair Niche air handling units which incorporate an intelligent Building Management System (BMS) specifically designed to optimise the energy savings provided by the technology. The SolarWall® system is expected to save 15.5 tonnes of CO2 per annum, whilst also providing extremely high levels of occupancy

Armstrong Point Business Park, Wigan comfort due to a constant supply of fresh ventilation air. During warmer periods, the SolarWall® technology also helps to keep the building cool by absorbing the summer sun and taking the heat striking the outer cladding away from the building. The renewable technologies will be continually monitored by the Carbon Consultancy Company and tenants will be able to see exactly what energy is being generated and consumed in their business unit at any one time via a dedicated display. This energy use will be broken down into heating, lighting and operational use with many sensors around the business unit measuring ‘real time’ information. Advanced monitoring software will

help to prove the savings and help tenants with continual improvement “We are delighted to be involved with Armstrong Point. All our knowledge and expertise in low and zero carbon and sustainable development has enabled the landlord to make the right choices from inception of the project through to construction.
Our role is also to help present the energy saving technologies to tenants at the site, to ensure Armstrong Point provides zero energy cost business space. Constantly we are reviewing emerging technologies to improve the final project” Con Ward, Head of Energy Services, Carbon Consultancy Company.
SolarWall® Originally developed by Canadian company Conserval Engineering Inc. during the late 1980’s, the Transpired Solar Collector (Branded SolarWall®) is a proven renewable energy technology that has been validated through extensive independent testing and third party monitoring on a global scale. ”Utilised in over 35 countries across 6 continents, SolarWall® is an engineered to order system with the highest known efficiency of any active solar technology in the world” – Dr. Chuck Keutcher U.S. National Renewable Energy Laboratory (NREL). During its development, the SolarWall® technology was vigorously tested at the world’s largest solar test facility – Bodycote’s
National Solar Test Facility in Toronto – and has since been rated in the top 2% of energy inventions by the U.S. Department of Energy.
SolarWall® collector absorbs the sun’s energy, heating the fine layer of boundary air that lines it’s external surface
The fresh, solar heated air is drawn into the building via a fan / heating unit and delivered via an air distribution system
The air space inside the SolarWall® is under negative pressure, drawing the warm air upwards
The SolarWall® technology is exclusively available in the UK from CA Building SolarWall® panels Products and as such has also been independently tested and verified within the UK climate
by the following respected bodies, BSRIA, DSA Engineering and Battle McCarthy.
