Presentation from John Forster, Chairman of Angus-based Forster Group, on roof integrated solar in Scotland at the Solar Trade Association (STA) Commercial Rooftop Event: Delivering Growth on Wednesday 1 April 2015 in London.

1. Roof integrated solar in Scotland
integrated products - integrated service

2. Who we are
 Scotland's largest roofing and solar contractor
 Proven track record built upon 25 years leading best practice in roofing
 Cover one in five of Scotland’s new homes
 20% of Scottish commercial rooftop PV
 Combining products and services to provide a fully integrated ‘Solar Roof’

3. What we do
Commercial roof-top and free
standing solar PV services
Combined roofing and solar PV
service on new build homes, social
housing, public and commercial
buildings

4. Integrating products
 Better aesthetics
 Building integrity and weather-tightness
 Fixing security
 Supports planning on sensitive sites/listed buildings

5. Solar PV tiles and slates
 Discreetly blends in with roof design
 Suitable in new build context or as part of a roof renewal
 Typically 50Wp-90Wp

6. In-roof PV systems
 Integrates with slated or tiled roofs
 Suitable in new build context, as part of roof renewal or as a retrospective
installation

7. Integrating services
 Combining with roofing works
 Reducing management of trades
 Avoiding duplication of infrastructure
 Consideration for integrity (weather tightness) of the building
 Safeguards new home warranties

8. Scottish context
 Scottish Government - 2020 renewable energy target - to generate the equivalent
of 100% of Scotland’s electricity demand from renewable sources by 2020
 Economic strategy to work towards further social equality and the reduction in
fuel poverty
 Climate Change (Scotland) Act 2009 - legally binding carbon reduction targets
 STA Scotland launched last month

9. Scottish new build context
 Sullivan Report -“A Low Carbon Building Standards Strategy For Scotland”
(2007)
 October 2010 Scottish Building Standards
 Reduce CO2 emissions from new buildings by 30% beyond 2007 standards
 Recommended 2013 Scottish Building Standards
 Reduce CO2 emissions from new homes by 60% beyond 2007 standards
 Reduce CO2 emissions from new non domestic buildings by 75% beyond 2007 standards
 Actual (2013) October 2015 Scottish Building Standards
 Reduce CO2 emissions from new homes by 45% beyond 2007 standards
 Reduce CO2 emissions from new non domestic buildings by 60% beyond 2007 standards

10. The solution
 The simple, reliable and cost effective measure in helping meet new build 2015
carbon reduction targets
 Attractive income and energy savings
 Integrated products, services and savings
 Seamless fit with site programme
 No impact on footprint

11. Athletes Village’
 Integrated roofing and solar PV
 703 homes (300 private, 400 social)
 1, 1.25, 1.5 and 2.25kWp systems
 Flat roof and In-roof PV systems
 Micro inverters

12. Barratt Homes
 Integrated roofing and solar PV
 Solar Century C21e PV tiles on variety of house types
 Power for homes or communal areas inc. corridor, stairway lighting

13. Social housing context
 SHQS - 1st April 2015
 Energy Efficiency Standard for Social Housing (EESSH)
 Target 31st December 2020
 Minimum Energy Efficiency (EE) rating - rating varies dependant upon the
dwelling type and heating fuel
 EESSH will mean that in the main no social property will be lower than a C or
D Energy Efficiency rating
 EESSH projected to provide benefits to social tenants of around £127million/year

14. Angus Council
 Sheltered housing complex
 Roof renewal and PV install
 Two 10kWp in-roof PV arrays
 Micro inverters to optimise performance
 Reduce energy costs

15. Commercial context
 Scotland has 25,000 hectares of south facing commercial roof space
 Potential investment value approx. £40billion
 Generate approx. £7billion savings for Scottish industry every year
 Reduce carbon emissions by approx. 15million tonnes every year

16. National Trust for Scotland
 Preferred PV partner
 Sensitively integrate solar PV into slated roofs
 Reduce the Trust’s electricity costs and cut fossil fuel use and carbon emissions
