Roland Hill• Established 1951• Domestic and Commercial Sector• Sustainable Solutions• All in House Trades• 50%of staff have over 10 years service• Accreditations• Experience
Introduction• Case study on a construction project• Overview of integration of renewable technologies• What does the future hold?
Case Study – How Cottage• Renovation Brief – To take 150yr old traditional lake district cottage. – Bring up to current building regulations. – Reducing heat loss allowing renewable energy to be a viable option.
Case Study How Cottage• Renovation – External Insulation – Internal Vacupor Insulation – New highly insulated roof – Heating system upgrade – Removal of the existing oil boiler – Heated by an Air Source Heat Pump
Case Study How CottageNew Extension•Provide a modular extension 180m2•Installed and water tight in one day.
Case Study How Cottage• New Modular Extension – 10 Modules due to access – Factory Built in 12 weeks – Wall/Roof = 0.12 W/m2k – Under Floor Heating Installed – 8kW Air source heat pump – 2.0 kW PV panels – Mechanical Ventilation and heat recovery
Case Study How Cottage• Conclusion – Seamlessly blended traditional and MMC – Highly innovative off site construction – Fabric first approach – Fully integrated renewables – Gives a comfortable efficient home for years to come…….
Integration of renewable energy• Get the right renewable for the building, one does not suit all. – Solar PV – Solar Thermal – Heat Pumps – Biomass• Take into consideration – Heat loss – Electricity supply – Local resources – Orientation of building
What does the future hold• EPC’s Green Deal• Improved building regulations• Renewable Objective• Reduction of carbon emissions• More efficient buildings less reliant on fossil fuel
