the aesthetically acceptable approach
Solar power on buildings20th Oct 2010
Welcome!
Lots of solar conferences out there…
thanks for coming to BRE!
What’s this conference about?
• Bringing building designers into the solar equation
• Looking at:– PV market– Aesthetically attractive products– without losing sight of the financial aspects
• Looking outwards from our island
Building Research EstablishmentA world leading centre of expertise for the construction
industry, providing research, consultancy and information services to customers worldwide.

UK Predictions
• UK PV installations expected to increase ten-fold this year (up from 10 MW in 2009)
SolarBuzz UK PV Market Survey 2010
• “..up to 500 MW of yearly installations in 2014 under a Policy-Driven scenario.”

Is this sustainable?
A better way?
we think so…

…practical, aesthetically good solutions
Standard modules can also be integrated

Design & multi-functionality
• Weatherproof skin
• Noise barrier
• Sun shading
• Heating & cooling
• Electricity

It is starting to happen on a small scale, but…
Effect of Feed-in Tariffs (FITs)
• No differentiation for BIPV
• Review April 2013
• France and Italy have BIPV premium FIT rate; lower rates for the more common installations
• More on FITs later..

Summarising drivers for BIPV
• Retrofit reaction (planners & public)
• Desire for green flagship buildings is increasing (e.g. Strata SE1)
• Cost of key PV components falling – cells, thin film
• Cost of grid electricity predicted to rise quickly, and supply is uncertain (affects all PV)
• FITs – adjustment to favour BIPV in 2013?
BIPV challenges - Education
Overcoming misunderstanding of capability and application of BIPV by:
• Educating public, planners & government before any reaction to retrofit affects whole market
• Demonstration of cost-effectiveness
• Demonstration good design & integration into buildings
Other BIPV challenges
• Clear route to certification for BIPV products• More BIPV for retrofit as well as newbuild• New building components required• Construction industry / PV workshop (BRE 2009)
highlighted these concerns:– Perceived system cost– Product lifetime - Warrantees– Aesthetic choices
• Making PV fit into our World, not vice versa
