Shared Vision



    To functionalise the
  whole building envelope.
   New build and existing

   To create buildings that
    are power stations to
   help deliver the low to
      zero carbon built
        environment

                 Sustainable Building Envelope Centre

Transforming the role of building envelope / fabric from passive fuel and energy
conservation to active generation of renewable energy, storage, distribution and
management. Done in partnership with enabling Building Services and associated
technologies to deliver environmentally sustainable and low to zero carbon buildings.
Research and Development
Technology For Generation

•   Transpired Solar Collectors (TSC)
•   PV
•   Combination of TSC and PV




Parallel / Boost Generation Systems working in tandem with
Renewable Generation (TSC / PV)

•   Conventional gas boilers and blowers
•   Heat Pumps (air source and ground source) for space heating and water
•   Immersion Heaters (Hot water)

                                                                  Roof
    Transpired Solar (air) Collectors (TSC)
    Solar collection with up to 50% conversion efficiency
•    A third skin with specially designed
     perforations to trap solar energy and
     convert it into heat

•    Usually integrated into south facing walls
     (roofs are also possible) and in most
     cases undistinguishable from the
     surrounding building envelope

•    Available in a range of attractive colours;
     suitable for retrofit or new build projects

     1000m2 of wall can produce 0.5MW;
                                                                                             Reduction in Gas Usage Due To SolarWall

Research and Development
Opportunities
Technology for Storage

•   Phase Change Material (PCM)
•   Roof / Wall / Floor as thermal mass
•   Foundation and ground (Thermal storage)
•   Water (Thermal storage)
•   Accumulators (Electric Storage)


Delivery mechanism

•   Existing High temperature wet systems (Typically Gas fired radiators)
•   Existing Low temperature wet systems (Typically Heat pump sourced)
•   Existing warm air systems
•   Biomass Boilers
•   Mechanical Heating Ventilation and Recovery systems.
•   New Low temperature wet systems using high emission steel surfaces
    (Comfort Vite) as ceilings, walls. Variation on Chill Beams.

    commercial and residential sectors.
         Applied research to compliment
           New Product Development
•   Fundamental understanding of TSC behaviour and performance leading to
    optimisation (New Coating, Perforations, profiles, air gap, substrate).

•   Enhance conversion of low grade heated air to electricity

•   Efficiencies of various methods of heat storage
    (PCMs, floors, ground, water, accumulators)

•   Convert the heated air generated by TSC to cooling.

•   Behaviour of heat pumps (impact on their efficiency) when working in tandem with TSC.

•   Energy models to predict generation by TSC and associated PV and subsequently to
    model the interactive performance working in conjunction with the rest of the
    booster, storage and delivery systems.

•   integrated into existing recognised (deemed to satisfy
    for regulatory purposes) software such as SBEM, SAP or similar DSM to facilitate
    approvals and uptake of products by the industry
