• 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
Some Lessons

Integrated Greenhouse ProjectPhase 2 (2007/8)
Green Greenhouse / Vertical Soil Heat Exchanger (VSHE)
The Problem
Unsustainable food (crop) production in energy-wasteful greenhouses, using non-renewable energy
Lack of integration of greenhouses with other buildings
Lack of investment in low-carbon design
Confusion 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 future
together • Blue sky thinking is needed
• Boldness or bust
• Beyond immediate CO2 reductions to potential for long term behaviour change (production methods, consumption patterns)
