SolarWall^®: Transpired Solar Collector (TSC)

The SolarWall^® Transpired Solar Collector (TSC) is an innovative solar air heating system that utilises solar radiation to deliver naturally warmed fresh air into buildings. With no moving parts, minimal energy running costs and minimal CO₂ emissions, the SolarWall^® technology provides a truly renewable heat energy source with payback periods of as low as 3 years for new build and 7 years for refurbishment projects.

The principle of the SolarWall^® system is simple. Installed as an additional skin to a building’s southerly facing elevation, the system consists of a pre coated, profiled steel sheet with thousands of tiny perforations uniformly spaced across the full face of the collector.

As solar radiation strikes the surface of the SolarWall^® panel and is absorbed, solar heat conducts to the thermal boundary layer of air which lines the outer surface of the panel. This heated boundary layer of air is then drawn through the perforations into an air cavity which is created between the SolarWall^® panel and the original elevation behind.

From the air cavity, the fresh, solar heated air can then be introduced directly into the building as ventilation air (industrial applications), or ducted into a HVAC unit (commercial & residential applications), where it can be used as a pre-heater for the building’s main heating system.

As a result of supplying fresh, solar heated air into the building, the SolarWall^® system can help to effectively eliminate internal negative pressure situations and heat stratification problems that can be associated with modern air tight constructions. The system can also be designed to meet specific regulatory ventilation codes as well as providing significant reductions in annual energy consumption and resulting CO₂ emissions

How the SolarWall^® System Works:

Independently Proven Savings

The SolarWall^® TSC has been independently tested, monitored, recorded and proven by BSRIA to produce heating cost savings of 50% and an independently thermally modelled report by Battle McCarthy proved SolarWall^® TSC can provide up to 20% of a building’s total energy requirements. SolarWall^® is recognised globally as a renewable energy form in its current right.

SolarWall^® now incorporated into next release of iSBEM v4.0.a

Funders, designers and building owners can now adopt this technology into the initial building design and using the latest version of iSBEM the savings made by Transpired Solar Collectors become apparent, especially when incorporated with the Twin-Therm^®/River-Therm^® systems, the final delivery ensures that all involved in the project delivery enjoy the very high EPC rating as well as enhancing the financial opportunities such as asset value, yield, running costs, or and in some cases the lowering of carbon tax as the demands become stronger to reduce CO₂.

A Renewable, Renewable

The SolarWall^® TSC system is now available with the Corus Confidex Sustain^® Guarantee, ensuring all of the unavoidable carbon emissions created throughout the entire life of the SolarWall^® cladding system, cradle to cradle, is offset by investing in environmental projects worldwide. Confidex Sustain^® Guarantee is available when Colorcoat HPS200 Ultra^® and/or Colorcoat Prisma^® are specified as part of the SolarWall^® system. Together provide the very best sustainable building envelope solutions.

Corus Colorcoat Prisma^® and SolarWall^®- Designed for roof and wall cladding systems, Colorcoat Prisma^® pre-finished steel is the product of choice for the additional skin of the SolarWall^® system.

It facilitates a very streamlined construction process due to its flexibility, durability and ease of handling, and has guaranteed quality and sustainable credentials. Manufactured using the most advanced technology available, the quality of Colorcoat Prisma^® is backed by BBA certification for a life expectancy in excess of 40 years, exceeding all other manufacturers by 15 years.

Colorcoat Prisma^® meets the sustainable sourcing criteria for BREEAM with all manufacturing sites having environmental management systems certified to ISO14001. It is entirely born and bred in the UK keeping transport to a minimum, so giving a low carbon footprint, and as a steel based system is 100 per cent recyclable at its end of life.

*Colorcoat, Colorcoat HPS200 Ultra, Confidex and Prisma are registered trademarks of Corus.

The renewable aesthetics of Colorcoat Prisma^® become even more attractive via the broad range of colours that are available. The design of the SolarWall^® system has minimal impact on the appearance of the building, which in many cases has made acceptance by planning easier when compared to wind farms, etc... which in some areas are unacceptable.
