GBT performs inspection and testing to identify conditions that lead to problems in indoor air quality or comfort and develop strategies to improve the customer's indoor environment. The strategies often require modification of the HVAC and control systems.

Project Design

GBT develops designs for energy saving and indoor environment improvement projects. We perform site inspections, calculations, computer modeling and ultimately produce construction documents such as the scope of work, project plans and project specifications.

Installation and Construction

We perform the installation and construction work. Some of the construction work may be performed by our forces and some may be performed by our subcontractors. Construction work is typically performed for a fixed price based upon the project plans and specifications or on a reimbursable cost plus fee arrangement. If the customer desires, the installation and construction can be bid-out by the customer and performed by others.

Building System Commissioning

After construction, we test, adjust and verify that all systems operate properly and develop and assist the customer with implementation of an operation and maintenance program.

Building System Re-Commissioning

In some cases, energy problems can be corrected through re-commissioning. Improper initial commissioning and/or alterations made to systems over a period of time can cause existing buildings to operate inefficiently and can cause indoor comfort or air quality problems. We correct these problems by first, reviewing original construction documents (if available). Next, we test and make an independent evaluation of all systems and equipment. Then we formulate and implement a re-commissioning plan to bring the equipment and building back into compliance with the equipment and building design specifications. Finally, we work with the building operations staff to establish an appropriate operation and maintenance program.
