Mechanical Engineering Capabilities – HVAC

Air-side Equipment and Distribution Systems

WFT delivers advanced hydronic supported and direct expansion air distribution systems tailored to the unique needs of each facility.

  • Large field erected air handling units.
  • Custom factory and knock-down central station air handling units.
  • Packaged energy recovery and DOAS units.
  • Package (economical) indoor and rooftop air handling units.
  • Single packaged rooftop heating/cooling units.
  • Unitary equipment for point of use applications.
  • Dilution exhaust equipment for laboratory exhaust applications.
  • Variable Air Volume (VAV) systems provide efficient, zone-specific air control.
  • Variable Refrigerant Flow (VRF/VRV) technology enables simultaneous heating and cooling across multiple zones while maximizing energy efficiency.
  • Chilled beam technology offers quiet, energy-efficient cooling ideal for offices,
    laboratories, and educational environments.

Hydronic Equipment and Distribution Systems

WFT delivers efficient hydronic systems to support air distribution systems tailored to the unique needs of each facility.

  • Air-cooled and water-cooled chillers using environmentally friendly refrigerants.
  • Cooling towers suitable for the specific environmental conditions with energy and water use reductions in mind.
  • Pumps and flow control devices to match the hydronic distribution quantities to the instantaneous varying loads.

Building Utility Systems 

CUPS • SCUBS • District Steam • High-Temperature Hot Water • Chilled Water Distribution

We focus on engineering reliable, high-efficiency utility systems that support building operations at scale. There is no one-size-fits-all reality to building systems.

  • A mechanical point of view – Central Utility Plants (CUPs) supply primary heating and cooling from a centralized location.
  • Satellite Central Utility Buildings (SCUBs) expand or supplement CUP capacity for large campuses or multi-building districts by setting up “regional” districts to reduce the individual length of distribution piping networks as well as reduction of overall distribution system piping pressure drops.
  • Steam systems provide essential distribution for heating, sterilization, humidification, and industrial processes.
  • High-Temperature Hot Water (HTHW) systems deliver robust heating for large buildings, district loops, and campus-wide networks permitting distribution of greater amount of thermal energy with smaller pipes.
  • Central chilled water systems permit the clustering of equipment within a central location to permit optimum operation and maintenance of the equipment, better control, greater redundancy and more flexibility of operations under changing load demands.

Specialized Systems 

Smoke Control & Evacuation

Our mechanical engineers design specialized systems that support heightened performance, sustainability, and safety.

  • Smoke control and evacuation systems are engineered to stringent life-safety standards, protecting occupants during emergency events.
    • Passive Systems – simplest form of smoke management.
    • Active Systems – can be a complicated to a very complicated form of smoke
      management.
  • Active Smoke Management integrates the fire alarm system with various dedicated airside systems and the actual thermal comfort HVAC systems in special ways to cause specific restriction of smoke movement throughout a facility with the emphasis on personnel safety.

Geothermal Systems

Our mechanical engineers collaborate with thermal well driving experts to develop the feasibility and design parameters leading to the successful design and application of this technology.

  • Geothermal systems leverage stable underground temperatures to reduce energy use and carbon impact.
  • Geothermal systems utilize the ground as a direct heat sink, one that is more consistent than air with many thermal advantages that far exceed those of the atmosphere.

Building Management Systems

WFT provides advanced tools and analysis to help building owners and operators drive
efficiency and long-term performance.

  • Building Management System (BMS) design and integration centralizes HVAC and utility control for real-time monitoring and data-driven optimization.
  • Direct Owner involvement in the BMS development process.
  • Development of all four control elements for successful BMS installation & operation:
    • BMS System Architecture.
    • Control Diagrams.
    • Point Lists.
    • Sequences of Operations.
  • Our solutions empower owners to make informed decisions and maintain consistent environmental quality while ensuring that each control system design provides the desired operation, monitoring and alarm functions needed without over-design complexity and costs.

Frequently Asked Questions

Our regional expertise, responsive engineering team, and integrated mechanical, electrical, and plumbing design approach together result in coordinated systems that deliver long-term performance, cost control, and energy efficiency.

  • Depth of experience in facility assessment, master planning and support of programming activities.
  • Depth of design experience utilizing Revit design tools to provide documentation of an integrated, coordinated and 3D spatially correct relationships for MEP systems with other building features.
  • Extensive construction phase support mechanisms to assist the Owner / contractor relationship to ensure that the appropriate construction equipment and materials are provided and commissioned to meet the expectations for each project.

A Central Utility Plant (CUP) provides primary heating, cooling, and power for a building or campus. A Satellite Central Utility Building (SCUB) adds capacity or serves a dedicated area of a large campus or facility.

We design a full range of HVAC solutions, including VAV systems for zoned air control and VRF/VRV systems for flexible, high-efficiency heating and cooling across multiple zones.

Chilled beam systems are ideal for buildings seeking quiet, energy-efficient cooling with reduced ductwork and improved occupant comfort, particularly offices, labs, and educational spaces.

Geothermal systems work best when a site has adequate land or borefield capacity and when owners prioritize long-term cost savings, energy efficiency, or sustainability goals.

A BMS centrally monitors and manages HVAC, utilities, and mechanical equipment, optimizing energy use, enhancing comfort, and streamlining maintenance.

Absolutely. We provide design services for upgrades, retrofits, and system evaluations for both new construction and existing facilities.

CUP-based systems are commonly used in large or multi-building settings such as hospitals, universities, laboratories, government facilities, and commercial campuses.
