Our glasshouses enable us to grow a range of tender plants that would otherwise not survive in Cambridge. These collections help fulfil our mission of providing collections for research and teaching.
Although glasshouses require energy to heat them, we look at ways of reducing this input. We are experimenting with maintaining lower temperatures, particularly in winter. We are monitoring the effect this has on our collections under glass. Perhaps we will be able to turn down the thermostat yet further.
Recently, investment in modern glasshouses has allowed the use of modern energy saving technology. Not only are the heating pipes and boilers efficient we have also installed thermal screens. These internal screens can be drawn over at night to reduce heat lost from the roof and sides – just like curtains at home.
