Energy efficiency is a measure of energy used for delivering a given service. Improving energy efficiency means getting more from the energy that we use.
DECC - Energy Efficiency Strategy: 'The Energy Efficiency Opportunity in the UK'
I came across the October 2013 edition of 'In Greenhouses' magazine today, and it contains some interesting articles.
These pieces particularly caught my eye:
'Know your physics for better greenhouse control' — dehumidifying research, looking at reducing energy use in greenhouse climate control
'Many colours influence the shape and development of the plant' — looking at the use of different coloured LED lights in horticulture. Read More...
A selection of presentations given by Tim Pratt and Jon Swain from Farm Energy Centre at 'Preparing your glasshouse for winter' — a GrowSave training event for energy-intensive ornamental growers. The presentations cover energy efficiency, fans and air movement, and biomass and the RHI. Read More...
Because supplementary lights also produce heat, they can have a sudden impact on the temperature balance of a greenhouse when they are turned on.
Get your control strategy right and the ‘waste heat’ from the lights can make a useful contribution to the heating needs of the greenhouse. Read More...
Supplementary lighting can be controlled in a number of different ways, ranging from simple manual switching through to automatic control using a climate computer.
Whatever method is used, the key is to maximise the effect of the lighting installation whilst minimising energy costs; so what is the best way to achieve this? Read More...
Notes from a presentation on lighting given by the GrowSave team, covering:
The efficiency of different lighting systems
How to replace lamps economically
The importance of maintenance
