Creating a sustainability experience, connecting global and local issues & promoting sustainable ways of living to safeguard future communities and ecosystems
Integrated Greenhouse Project Phase 0 (2003/4)SEEDA 2003Seed funding - £40k GreenSys 2004Established partnerships with Professor Gerard Bot and team at Wageningen University, and the renewable energy team at TV Energy
EC Life Environment Unit 2.3m € funding Integrated Greenhouse Project
Integrated Greenhouse ProjectPhase 1 (2005/6)Human Impact Building Purpose: To demonstrate sustainable low-carbon design, operation and use
Our Heating Journey… from oil to local wood chip CO2 emissions per unit of energy supplied 450 400 350 Woodfuelled heat 300 Wind power Grams of CO2 per kWh 250 Solar PV m-si Solar PV p-Si 200 Natural gas heating 150 Light fuel oil heating 100 50 0 ... the first public indoor rainforest garden to convert to wood chip heating
Some Lessons • Integration, part 1: biomass & oil • continuity of supply? • put all heating devices ‘behind the heat storage bunker’? • Integration, part 2: ground source heat storage & biomass
Integrated Greenhouse ProjectPhase 2 (2007/8)Green Greenhouse / Vertical Soil Heat Exchanger (VSHE) The ProblemUnsustainable food (crop) production in energy-wasteful greenhouses, using non-renewable energyLack of integration of greenhouses with other buildingsLack of investment in low-carbon designConfusion about what is ‘best practice’ among growers and government

Direct energy expended by various sectors of agriculture in the UK by use in 2005 (from: Warwick HRI 2007).
Horticulture 101 • Fruit & vegetables account for 2.5-3% of UK greenhouse gas emissions (Garnett, 2006) • UK horticulture accounts for about 28% of all energy used in UK agriculture • UK protected crops covering 749 ha used 3,318 GWh / year (Warwick HRI, 2007)

Let’s build a sustainable futuretogether • Blue sky thinking is needed • Boldness or bust • Beyond immediate CO2 reductions to potential for long term behaviour change (production methods, consumption patterns)
