Energy Management System

BD Engineering has over 16 years of experience with Energy Management System (EMS) design and commissioning. We can specify and prepare designs for all of the major control manufacturers for every application including lighting, HVAC and refrigeration systems. We specialize in designing a system that is tailored to your needs and will safely minimize your energy consumption while ensuring functional and comfortable lighting, temperature and humidity levels in your facility.

BD Engineering has extensive experience in designing and commissioning refrigeration system controls. In a typical supermarket the refrigeration systems utilize roughly 50% of the electricity consumed and refrigeration systems are required to run around the clock, 365 days a year. If these systems are not properly controlled to run at maximum efficiency, the real cost to you can be significant. Let BD Engineering help you get the most of your energy dollars. Let us design and commission an EMS system for you that will work to reduce your energy costs by providing the following:

Lighting Controls

  • Control lighting levels based on time of day, and interior & exterior lighting level sensors
  • Occupancy sensors to control office lighting
  • Provide multiple levels of lighting to match operational needs

HVAC Controls

  • Provide programmable controls to accommodate operational hours, holidays, night & weekend schedules
  • Control temperature and humidity levels to optimize comfort and reduce loads on the refrigeration systems
  • Reduce demand during peak energy rate periods
  • Use variable air volume systems (VAV) to allow individual local control based on local load conditions

Refrigeration Controls

  • Float the suction pressure up and the head pressure down to reduce energy consumption
  • Cycle compressors to best match the current and predicted loads
  • Split the condensers and cycle the fans during periods of low loads and low ambient temperature
  • Utilize anti-sweat heater controls to cycle or turn off the anti-sweat heaters during periods of low humidity
  • Utilize variable speed drives
  • Reduce demand during peak energy rate periods
  • Monitor product temperature and generate alarms when temperatures reach a predetermined level or as a result of a component failure

Are your existing control systems up to par? Then let BD Engineering re-commission your EMS system to ensure that everything is functioning properly and is fine-tuned to optimize your energy usage. Frequently contractors will “jump out” portions of the control system in order to provide a quick fix for an unresolved problem. These fixes can operate undetected for years, wasting your valuable energy dollars. Let BD Engineering verify proper operation of your systems by inspecting and testing the EMS system including:

  • Interrogate your EMS systems and document all of the existing systems, controls and setpoints. Provide a written report for your records.
  • Verify proper operation of all sensors and transducers.
  • Sensors and transducers typically "drift" over time and need to be re-calibrated.
  • Physically verify proper operation of all contactors, stages of heat, stages of cooling and all other functions.
  • Provide a back-up of the final control set up for use in case of a failure at some future date.
  • BD Engineering is your best resource for getting the most out of your energy dollars.
