5 Simple Ways to Improve Building Performance

2024-07-04T08:12:30+00:00

As a facility manager, you're likely always looking for ways to improve your building's performance and reduce energy consumption. One of the ways you can accomplish this is to implement a retro-commissioning program within your facility. Retro-commissioning, or RCx, involves identifying and fixing problems in an existing building's systems to optimize performance and reduce [...]

What is Retro-Commissioning?

2024-07-04T08:13:33+00:00

Retro-Commissioning (RCx), sometimes referred to as Existing Building Commissioning (EBCx), is an important process for optimizing the performance of existing buildings. It involves the comprehensive evaluation of a building’s systems, their components, and how they interact with each other. The goal of RCx is to identify areas of improvement in the building’s operation maintenance, [...]

Why You Should Select a Third-Party Commissioning Provider

2024-07-04T08:14:52+00:00

As the field of commissioning has grown and evolved over the past 25+ years, it has become a valued component of building projects in the Architecture/Engineering/Construction (A/E/C) industry. There are hundreds of highly respected and qualified commissioning providers throughout the country. Many of them are part of a team within larger engineering firms. When [...]

ECM Tip #10: Optimizing Variable Air Volume Lab Airflows

2024-07-04T08:15:03+00:00

Laboratories, whether in a college/university, medical building, or research facility, are one of the highest energy-consuming functions in any building. Lab spaces require large amounts of outside air, have high air change rates, and in many cases strict space temperature and humidity requirements. The HVAC systems that serve these spaces typically operate 24/7, 365 [...]

ECM Tip #9: Supply Air Temperature Reset

2024-07-04T08:15:14+00:00

When a multi-zone variable air volume (VAV) air handling system is designed, you might notice that the scheduled leaving air temperature of this unit is about 55°F. Why is that? The 55°F setpoint is based on the typical cooling space temperature and relative humidity (RH) setpoints commonly needed in buildings, which typically ranges from [...]

ECM Tip #8: Hot Water Supply Temperature Reset

2024-07-04T08:15:26+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

2024-07-04T08:15:39+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

2024-07-04T08:15:51+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

2024-07-04T08:16:02+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 [...]
