“JH Kelly’s depth of knowledge and expertise in building mechanical systems makes them a very valuable partner in constructing high performance buildings and obtaining LEED certifications per the owners’ design criteria.”

- STACEY LIN, PE, Principal / Interface Engineering


With over 4 million sq ft of LEED-certified buildings, we have learned that, while earning certification is important, measured efficiency and functionality enhance value for the owner and building users.

JH Kelly works in tandem with the design team to develop and implement pragmatic approaches to maximize energy efficiency, minimize waste, and increase overall environmental quality and occupant comfort within project cost parameters.

We have installed green systems ranging from eco roofs to bio-reactor processing of sanitary waste; from heat recovery systems to open/close loop geothermal; and from low flow fixtures to high efficiency equipment.
