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 [...]

What is Monitoring-Based Commissioning?

2022-09-30T12:14:14+00:00

Every few years the Leadership in Energy & Environmental Design (LEED) certification program goes through a review process and is updated to reflect the constantly changing technologies of today’s world and ways in which to leverage them to improve building performance. When the LEED program was updated to Version 4, a new option was [...]

The Benefits and Uses of Infrared (IR) Thermography

2022-09-30T12:11:28+00:00

Seeing the Invisible There are few instruments that can provide as much information in a short amount of time as the infrared camera. The IR camera offers a look at how heat energy is moving within a system by showing infrared radiation not visible to the human eye. Infrared thermography (conducted using an IR [...]

An Overview of ASHRAE Guideline 36

2022-09-30T12:10:04+00:00

Since the beginning of the modern HVAC industry, the design, installation and testing of a building automation system (BAS) has remained relatively untouched. The process is as follows: First, an engineer will develop control drawings and desired sequence of operations for the various pieces of HVAC equipment in their design documents. From there, an [...]
