ASHRAE and the United Nations Environment Program will work together to publish a new Guide for Sustainable Refrigerated Facilities and Systems.

This $400,000 project is being jointly funded by the American Society of Heating, Refrigerating and Air-Conditioning Engineers and a fund that backs the Montreal Protocol, a 1987 treaty that established limits on substances that destroy the ozone layer.

The project is scheduled for completion in early 2014.

The guide will address the entire range of facility and equipment design and efficiency alternatives for refrigerated processing, storage and distribution in developed and developing countries.

The guide will also be important as parties to the Montreal Protocol face upcoming compliance deadlines. For developing countries, this means a freeze in hydrofluorocarbon consumption and production by Jan. 1, followed by a 10 percent reduction in 2015 and 97.5 percent reduction by 2030. Currently, HCFC-22 is the preferred refrigerant for many facilities and systems, but this ozone-depleting gas is being phased out. The guide’s goal is to support the selection of alternatives while maintaining or improving energy efficiency across the entire cold chain and reducing the environmental footprint.

“This is the largest collaborative project ASHRAE has undertaken with UNEP and truly represents our global leadership approach to solving society’s issues,” said Ron Jarnagin, ASHRAE president. “We, with our partner associations, look forward to working with UNEP on this extremely important refrigeration guide.”
