LED Lighting Incentives can help with On-Farm Trials

Thanks to the IESO for contributing to this post.

SOE logoAre you aware that the Save on Energy program can help you to complete energy efficient upgrades in your greenhouse?  You may have participated in this program in the past, but the current iteration can help you to retrofit items like ventilation fans and upgrade to LED lighting in the warehouse and the greenhouse.

The IESO has developed tools that can help you identify areas where an upgrade might be able to help you save energy.  These include a checklist that walks you through the greenhouse, and some videos and other information on their web page.

Upcoming Webinar: GO-CALC – Modelling Energy Use and Savings in the Greenhouse

Now that the mums are gone, and the poinsettias are getting ready to colour up, it’s becoming clear that winter is just around the corner.  With the colder temperatures outside, comes the ramping up of you heating system. Remember those energy bills from winter’s gone by? Have they got you thinking about doing some energy-efficient upgrades in your greenhouse?

The engineers at OMAFRA have been especially busy this year building GO-CALC – a tool to help estimate your energy use in the greenhouse AND how retrofits can help to make your greenhouse more energy-efficient!  The tool shows how those energy-efficient upgrades like energy curtains, new greenhouse coverings and boiler upgrades that you may already be planning for your greenhouse can help you save energy.
