Dear Grower, as you know energy can be a significant cost in greenhouse cropping. Currently NSW DPI is involved in an industry project developing some resources and energy saving technology demonstrations to help you improve energy efficency and save money.
There is also a PhD student undertaking research into energy efficiency in greenhouses. To assist in this study, you are invited to participate in a brief greenhouse energy survey. It will take less than 5 minutes to complete the questionnaire.
Your participation in this study is completely voluntary and your information will remain anonymous. You can withdraw from the survey at any point.
If you have questions at any time about the survey or the procedures, you may contact Jeremy Badgery-Parker by email at
[email protected]
Thank you very much for your time and support. Please start with the survey now by clicking on the
