Co-generation systems allow buildings to obtain all their heating and power needs from a single, integrated infrastructure. JEC designs customised co-generation plants that meet customers' most stringent economic and environmental requirements. JEC has experience combining heating and cooling by using cutting edge gas turbine generators and waste exhaust to generate electricity and run chillers.

JEC works in partnership with leading photovoltaic manufacturers to deliver BIPV systems that are uniquely tailored to the specific needs of different buildings. In addition to solar JEC has expertise in the sourcing and installation of wind turbines.

We recognise the growing importance of biodiesel as an alternative, cleaner fuel resource. We keep abreast of the newest developments and partner with leading technology suppliers.

JEC can provide district cooling systems that distribute a cooling medium from a centralised source, reducing the need for multiple heat rejection facilities. This solution can help improve urban ambient conditions as well as reduce overall operational costs.
