The challenge

Building efficiency retrofit.

When property managers Cushman & Wakefield decided to upgrade their office building at 160 Gould Street in Needham, Massachusetts, they knew they needed partners with expertise in advanced energy solutions for commercial properties. The three-story, 139,000 square foot building was built in 1986 and its operational efficiency and overall tenant experience were not meeting expectations.

Cushman & Wakefield selected EnergySource and FMC for their experience with cost-effective, energy-efficient building system retrofits. Together, they crafted a strategy to reduce electrical energy usage without compromising tenant comfort.

The solution

HVAC system optimization.

FMC shared its knowledge in advanced HVAC systems to strengthen the overall EMS implementation. FMC evaluated 160 Gould Street for retrofit opportunities that aligned with Cushman & Wakefield's objectives, budget, and ROI guidelines. Based on their evaluation, FMC added 162 variable air volume (VAV) terminal boxes located throughout the building which interfaced with the rooftop units (RTUs). Each VAV terminal box was then placed under direct digital control through the EMS. The EMS provided remote and centralized HVAC system control with custom programming capabilities.

  • Sequence 01

    Static pressure reset

    Optimized fan speed and pressure settings to reduce unnecessary air movement while maintaining comfort levels throughout the building.

  • Sequence 02

    Night temperature setback

    Automated temperature adjustments for VAV terminal units during off-hours, eliminating energy waste when the building is unoccupied.

  • Sequence 03

    Night cycling RTUs

    Intelligent rooftop unit cycling with strategic gas heat deployment during winter months to balance comfort and efficiency.

  • Sequence 04

    Economizer optimization

    Advanced control sequences that maximize natural ventilation and outdoor air cooling, reducing mechanical cooling and heating loads.

The results

Significant energy savings achieved.

Through the collaborative EMS implementation, 160 Gould Street showed significant results immediately. The local utility company's assessment determined that the reduction in electrical energy usage will add up to over $33,000 in cost savings each year. The advanced energy sequencing led to reduced fan power energy use and electric heating and cooling loads.

Direct digital control over the RTUs and VAV terminal boxes enabled better control and monitoring of the temperatures. Cushman & Wakefield were able to achieve the ROI they needed, and improve the occupant comfort their tenants value.
