    Energy



    Saving Energy From the Top Down

    HVAC systems are typically a building’s largest energy user. HVAC first-costs account for just 43% of the life-cycle expense. Maintenance and repair add another 7%, leaving a full 50% of life cycle costs to energy usage.

    Wiegmann engineers understand how to design an HVAC system that saves money now, and saves more over the life of your building.

    Whether we design your HVAC system or value engineer an existing design, our focus is on simplicity and proven reliability.

    “We were awarded the $35 million contract for a state correctional facility in Pennsylvania despite not coming in the lowest bidder because energy analysis demonstrated that our design would save more than $1 million over the difference in the bids over the 20 year life span of the system,” said Gerry Wiegmann.  “It is good business to be in the energy business.”

    Energy Projects

    A Multi-Tiered Approach

    Right-sizing systems not only saves money up front but also generates long- term energy savings and improved environmental conditions. We streamline ductwork and piping systems and select equipment that is sized for the actual load. We build safety factors into our designs where it counts and does not impact system performance. This often results in the need for less equipment, which means reduced electrical and structural work and a lower overall construction budget.

    We are also experts in Building Automation Systems, which provide a detailed view of how HVAC systems really operate and insight into how to properly apply systems on future projects.

    Saving energy is our promise, and we deliver. In addition to saving upfront costs, our energy saving techniques generate annual savings that many times lead to a simple pay back of the initial project costs in three to five years. These savings continue for the life of the building.
