A Greenhouse Energy Conservation Checklist has been developed to help you review a greenhouse operation and identify areas where energy consumption can be reduced. There are many aspects of a greenhouse operation that should be considered in order to optimize the efficiency of a greenhouse. Resources from eXtension Farm Energy include:
- Combat Higher Fuel Prices with Efficient Heating Systems
- Greenhouse Ventilation
- High Tunnels – Low Cost Seasonal Growing Space
- Natural Ventilation in High Tunnels
- Horizontal Air Flow is Best for Greenhouse Air Circulation
- Insulation Know-How
- Selecting and Maintaining Greenhouse Thermostats
- Step Controllers Optimize Greenhouse Energy Use
- Fuels and Alternate Heat Sources for Commercial Greenhouses
Strategies and Checklists
- Greenhouse Energy Conservation Checklist by John Bartok, Univ. of Connecticut agricultural engineer emeritus. A brief but comprehensive summary of steps growers can take to reduce greenhouse energy use.
- Top 10 Things a Greenhouse Grower Can Do To Improve Energy Efficiency Penn State University fact sheet. (2010)
- Greenhouse Energy Cost Reduction Strategies. PDF files compiled on Michigan State University Website from various sources.
Construction and Comprehensive Greenhouse Guides
- Virtual Grower, from USDA, is a decision support tool for greenhouse growers. Using this downloaded software, you can “virtually” build a greenhouse with a variety of materials for roofs and sidewalls, design the greenhouse style, schedule temperature set points throughout the year, and predict heating costs for over 230 sites within the US. Different heating and scheduling scenarios can be predicted with few inputs.
- Greenhouse Engineering. Available from NRAES: Natural Resource, Agricultural and Engineering Service for $30. This 212 page printed manual, NRAES-33, contains current information needed to plan, construct, and control the commercial greenhouse. Describes various structures, methods of materials handling, the greenhouse environment, and energy conservation. Includes conversion tables, worksheets for performing calculations, and sources of greenhouse construction materials and contractors. (1994)
