Building Envelope Testing (BET) determines the air and water leakage rates at standard pressures, and is often a regulatory requirement. Test areas can range from single rooms to a complete, multi-story building. BET is usually combined with Infrared Imaging Testing to identify breaches in the envelope.

Commissioning (Cx) is a systematic process for ensuring building systems (mechanical, electrical, plumbing, envelope, etc.) function and perform as intended. It includes design review, verification of equipment installation and observation of modes of operation. This process can be applied to new buildings and major renovations (Cx) or existing buildings (Retro-Cx). Software data analytics can also be set up to continuously monitor operations and flag potential issues (Monitor-Based or Ongoing Cx).

By partnering with trusted electrical design experts, we manage the full MEP design scope under one contract, ensuring flexibility, streamlined coordination, and seamless solutions for project teams and owners.

Fire Smoke Dampers (FSD) are located at HVAC duct penetrations through fire rated walls, ceilings, and floors. The function of these devices is to prevent fire and smoke from propagating through HVAC ductwork—giving occupants time to exit the facility and help minimize building damage in the case of a fire. Testing and maintaining Fire Smoke Dampers verifies and documents that critical FLS building systems operate as required. For more information on FSD, please click here.

Cleanroom Performance Testing (CPT) encompasses a number of different tests, depending on customer requirements, including Particle Counts, Ventilation Rates, Room Pressurization, Velocity Uniformity, Temperature and Humidity Measurements, and Filtration Verification. For more information on CPT, please click here.

Testing, Adjusting, and Balancing (TAB) involves measuring and adjusting air and water flows to meet design criteria. TAB is a vital step for complex air and hydronic systems within buildings and throughout campuses to ensure HVAC systems are optimized for occupant comfort, energy efficiency, indoor air quality, and manufacturing processes.
