The Problem
Unsustainable food/crop production in energy-wasteful
greenhouses, using non-renewable energy
Lack of integration of greenhouses with associated buildings for
improved energy management
Lack of investment in low-carbon footprint greenhouses
Confusion about what is best practice for producers and consumers
Greening the Greenhouse:
“so much for the theory”

integration part I
continuity of supply
how big is your bunker?
Infinity and beyond, integration part II
No questions please, wait for the workshop

Greening the Greenhouse:
“so much for the theory”
• integration part I
– If demand < capacityBiomB = happiness
– If demand > capacityOilB = happiness
– If demand > capB < capO = disquiet!
• put both devices ‘behind’ the buffer?
• discuss…remember the workshop

In conclusion…
We’re proud of our biomass boiler
We’re going to make it work
Bring on the GSHP!
If we knew then what we knew now …
Workshop anyone?
Thank you!
