Description Mechanical Engineer

Developing a detailed test, balance plan

The demand from building owners for contractors to maintain a construction schedule is growing every year. Building owners require a substantial construction completion date to be established and expect the construction team to meet this date to occupy the building on time.

Before a building can be occupied, there are many required processes throughout the course of construction that ensure the building is properly functioning and operating at the design intent. One of the most important is the process of total system balancing by means of testing and balancing the heating, ventilating, and air conditioning systems (HVAC). HVAC systems that lack a total system balance can result in inadequate indoor air quality, building/space pressurization issues, excessive energy consumption, and comfort issues for building occupants.

The testing and balancing process primarily consists of testing the HVAC equipment to ensure proper installation and design operation, adjusting/balancing the HVAC equipment to obtain the design intent and the most optimal level of system performance, and providing a report detailing the final HVAC system operation as compared to the system design. The testing and balancing report is typically reviewed by the mechanical design engineer and the building owner to verify that the HVAC systems are installed properly and operating as designed. The report will also document any deficiencies preventing a HVAC system from operating as designed if the design intent could not be achieved with the installed HVAC equipment. The HVAC system performance data documented within the report can be used to determine possible changes to the system design to achieve the design intent of the building. More and more often the report is also being reviewed by the city or state inspector to verify that proper indoor air quantity requirements are being met prior to occupancy.

Most construction schedules incorporate the testing and balancing process at the end of the project, usually to receive a certificate of occupancy. However, often there is not enough time for the testing and balancing contractor to complete the total system balancing prior to the completion date of the construction schedule. Failure to complete the balancing within the scheduled time can result in the general contractor, and, more importantly, the building owner being displeased with testing and balancing company regardless of the outcome of the final balanced systems.
