Axiom Engineers: Commissioning New Construction

This LEED 2.2 New Construction expanded the historical library with a major addition attached to the existing building. The ventilation system utilized wall diffusers and crawlspace duct to maximize the interior design open space. Commissioning services verified numerous control strategies employed in this building to achieve the LEED 2.2 Silver rating. Control strategies commissioned included demand control ventilation, crawlspace air management, and dual duct variable air volume systems.

Adequate and efficient air delivery was verified as part of the air balance audit which resulted in several system adjustments. In addition, Axiom Engineers℠ discovered numerous faulty control issues during the commissioning process. The controls were reset to proper working order, thus assuring occupant comfort and safety.

Project Summary

• 11,700 square feet.
• 15 dual duct variable air volume boxes installed.
• Utilized crawlspace exhaust fan and control dampers to control cold deck inlet air temperature.
• Verified numerous control strategies, including demand control ventilation, terminal box discharge temperature, crawlspace air flow management, and duct static pressure.
• Analyzed advanced trending and energy efficiency monitoring control system

Project Accomplishments

• Corrected economizer control for efficient mechanical cooling system use.
• Corrected cold deck air handler fan speed to provide adequate building air flows.
• Simplified dual duct variable air volume box heating sequence of operation.
• Discovered incorrect heating air handler filter arrangement.
• Verified correct duct static pressure control response through remote access.
