Sustainability Case Study

Affinity Engineering

Sustainability Case Study


The client, a retail furniture chain with locations across the United States, observed that its Glendale, NY location had high utility costs and decided to conduct a partial renovation of its 43,500 square foot retail store. Affinity Engineering acted on the client’s behalf to perform energy saving calculations and applied for and secured financial incentives offered by ConEdison, the power utility.

Project Summary

The client installed an energy management system (EMS) to control and
monitor its existing heating and cooling equipment. The client also
installed one supply fan variable frequency drive (VFD) on each of the
store’s nine rooftop units (RTUs), optimizing HVAC performance by
enabling output based on load requirements. Several control strategies
implemented include:

  1. Optimal start/stop
  2. Demand control/CO2 ventilation
  3. Zone by zone scheduling
  4. Unoccupied temperature setback
  5. Outdoor air temperature heating and cooling lockout


Installing supply fan VFDs and an EMS allowed the client to realize greater
automation and control of energy consumption with the ability to
remotely sched
