ECM Tip #8: Hot Water Supply Temperature Reset

2022-09-30T12:29:46+00:00

When designing a building’s heating hot water system, determining the peak heating hot water supply temperature is a critical decision. These systems provide heat to air handling systems, perimeter radiation, radiant panels, fan coil units, reheat VAV boxes and other hydronic heating elements. The hot water supply temperature (HWST) must be high enough to [...]

ECM Tip #7: Demand Control Ventilation

2022-09-30T12:29:09+00:00

Implementing and Effective Demand Control Ventilation Strategy When an air handling system is designed, ventilation air requirements are one of the most important aspects. The amount of outside airflow (ventilation) required for a system is dependent on how the space is used. Does the air handling unit serve a gymnasium or an office building? [...]

ECM Tip #6: Optimizing Economizer Parameters

2022-09-30T12:28:27+00:00

Imagine being in your home on a breezy, cool day. You’re cooking in the kitchen, kids are running around the house, and next thing you know, everyone is feeling a bit warm. What do you? Most people would open windows to cool down the house before turning on their home air conditioning system. This, [...]

ECM Tip #5: Single Zone VAV Control

2022-09-30T12:27:40+00:00

Converting a Single Zone Air Handling System to Variable Air Volume Control In the 1880s, Nikola Tesla invented and was granted a patent for his three-phase, alternating current induction motor, a device that was leaps and bounds more dependable than the direct current motors of the time.  However, it was not until nearly the [...]

ECM Tip #4: Installing VFDs on Pumps

2022-09-30T12:27:04+00:00

Remove the Brakes on Your Pumps by Installing VFDs It is quite commonplace to find variable frequency drives (VFDs) installed on pumps in any new construction or retrofit project and of course, they are necessary for any type of variable volume pumping system.  However, VFDs can also be utilized on constant flow pumping systems.  [...]

ECM Tip #3: Trim & Response

2022-09-30T12:24:20+00:00

HVAC System Trim & Response Resets When a building is newly constructed, one of the last steps performed on the HVAC system is the testing, adjusting, and balancing (TAB). The purpose of TAB is to verify the design air and water flows are properly supplied throughout the building. One of the most critical components [...]

ECM Tip #2: Optimal Start and Stop

2022-09-30T12:25:07+00:00

Before the days of advanced control systems, buildings would be preheated or precooled prior to occupancy using a standard warm up or cool down mode of operation. These primitive sequences would start the air handling units at a set time interval before the building entered into occupied mode. The air handling unit would then [...]

ECM Tip #1: BAS Schedule Adjustments

2022-09-30T12:25:39+00:00

Discussing building energy management can be overwhelming. Everyone wants to save energy and money, but utility contract negotiations, retrofitting HVAC systems, renewable energy, and battery storage can add a lot of complexity to the conversation. With numerous retro-commissioning projects under our belt, we want to share our knowledge with building owners and facility managers [...]
