Environmental Focus

A great building balances energy conservation, sustainability and provides safe air quality.We implement this approach by constantly analyzing new technologies and equipment as they become available which allows us to choose the best applications for each individual building we design. A few of the technologies we have implemented include: geothermal heat pump, high efficiency boilers, wood fired boilers, variable air volume systems, ventilation air heat recovery, decoupled ventilation with terminal heating/cooling, displacement ventilation, heat recovery chillers, variable speed pumping and innovative control strategies. All are viable HVAC solutions with their own advantages.

The quantification of "green building design" under the LEED certification process is a welcome development in our view. Most, if not all of the buildings we have designed for many years would have met or exceeded the intent for LEED certified HVAC systems. Our buildings consistently exceed national energy efficiency standards.
The environment strives to maintain a balance. A balanced building respects the needs of the owners and the people who will occupy the building with energy conservation and the initial cost of construction. That's just smart design.

What is LEED?


LEED is the acronym for Leadership in Energy and Environmental Design and is the Green Building Ratings System developed by the U.S. Green Building Council. The system was developed to encourage environmental awareness from architects, engineers, government agencies, developers and builders.

What is LEED certification?

A project can be LEED certified if it can document that it was designed and built using environmentally friendly building practices during construction or remodeling. There are four different levels of LEED certification: Certified, Silver, Gold and Platinum.
