The 100 yard range requires a constant 70,000 cfm moving through the range to maintain the required air velocity to keep the dirty air moving away from the shooters. Additionally, half of the total airflow is constantly removed by an exhaust fan that operates in parallel with the air handler. Once we completed the system balance and verification testing, we set off a smoke grenade to get visual documentation of the air flow moving down range.

Best Group performed a complete system evaluation of this four-story, interdisciplinary lab research building. Throughout the evaluation, Best Group measured all supply and exhaust air flows as well as associated hydronic equipment. As an added step, Best Group also performed a comprehensive pressure map of the entire building. Many deficiencies were identified across the spaces and equipment. Challenges included a lack original TAB information, incomplete building controls (BAS), and aging equipment. Best Group's efforts will provide valuable, baseline performance information for future renovations and improvements.

Georgia State University Petit Science Center Building is a 10 story mixed use building containing research and teaching labs, classrooms, and offices. Best Group provided the services for recent projects that included a complete upgrade of the building automation system. Our measurements were used to calibrate the upgraded BAS and to provide the verification that the spaces are operating with the correct room pressurization relationships, required air changes per hour, and climate control.

A Sandy Springs office complex consists of three high rise office buildings comprising a total of 1.5 million square feet. Cousins Properties strives to maintain the optimum indoor climate for the numerous occupants of these buildings. Best Group provides Testing, Adjusting, and Balancing (TAB) services for various tenant and owner projects. The services include pre-construction testing, post construction TAB, and system evaluations.
