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'
  • At the end of February 2014, twenty growers and horticultural industry professionals from the UK visited Ontario and British Columbia on a greenhouse horticulture study tour, organised by the GrowSave team. The group visited 14 organisations which comprised of nurseries, R&D facilities and industry suppliers.
  • There is increasing evidence that using diffuse light within a greenhouse can give production advantages, such as an increase in yields and reduced time to market, as well as quality improvement.
  • Here is presentation given by Dutch consultants on the 29th January. Growers who attended this event heard how the drive to save energy, and to grow more sustain-ably, was seeing fundamental changes to glasshouse cropping practices in the Netherlands.
  • It is now well proven that retractable thermal screens can save energy without having a detrimental effect on plant growth or quality; and you might even argue that a screen is now also an essential tool for both energy saving and
  • The use of thermal screens has become common place on many edible crop nurseries. They've been shown to save large amount of energy, paying back their cost quickly. In 2005, HDC project PC 198 showed that a thermal screen could save 100 kWh/m2 p.
  • This article explains some set points you can use with your climate control computer to control when your greenhouse screens open and close in relation to time of day and light level..
  • Because supplementary lights also produce heat, they can have a sudden impact on the temperature balance of a greenhouse when they are turned on.
  • In our article 'Where should you position your measuring box?', we showed how relying on a measuring box placed in the traditional position at the top of a tomato crop can give non-optimised control of the greenhouse environment and lead to wasted energy.
