Connecticut Grower Installs Energy Efficient Double Thermal Screen

Tthermal screen under constructionaking steps to reduce their energy usage, Cromwell Growers has taken advantage of the NRCS Environmental Quality Incentives Program (EQIP) to install 166,000 sq. ft. of state-of-the-art double thermal screen in their greenhouse.

The Dutch-style gutter-connected greenhouse replaces 19 individual greenhouses destroyed by the heavy snow of 2010/2011.

Double layer thermal screenThe double layer thermal-screens reduce energy use, and emissions. Other energy efficient features installed as part of the greenhouse design (at owner expense) include computerized environment controls for ridge vents, ventilation fans, irrigation – including flooded floor irrigation, multiple natural gas boilers, insulated pipes and sidewalls, energy efficient lighting, and pumps.
