Design Program: The building owners were experiencing difficulties maintaining temperature control of the exterior office space. Byce & Associates, Inc, engineered the HVAC system and specified the temperature controls. The systems were installed and balanced and the office area was occupied. The occupants began to experience problems keeping their offices warm during winter conditions. Byce & Associates, Inc. was hired to lead the commissioning of the systems in conjunction with the temperature control contractor and mechanical contractor.
Challenges: After extensive verification of proper installation of all components of the HVAC system and control points, it was discovered the cause of the problem was in the building envelope. Infrared thermal scanning technologies were utilized to located the precise envelope deficiencies. Locating the infiltration points through the thermal scan, the sub-contractors were engaged to rectify the situation. Once the infiltration was eliminated, the HVAC system was functionally tested and documented. Findings and resolutions were presented to the owner and occupants and all were satisfied with the outcome.
Scope of Commissioning Services: The HVAC systems consisted of energy recovery units, air handling units, variable air volume terminal units, exhaust fans, return air fans, hot water and chilled water systems as well as the DDC Building Management System.
