Mechanical Engineering

Pairing innovation with purposeful design to create comfortable spaces

Mechanical and HVAC systems commonly use more energy resources than any other system in a building. However, a good mechanical design is more than just energy efficient. Project budget limitations, occupant comfort, and system maintainability are other elements that must be considered as well. At HTW, we are careful to analyze all of these factors to deliver a design that is best suited to the project requirements.
