How to Choose the Best HVAC Office Design

For too many years our AEC industry has relied on past experience to continue to design and install systems for offices that are grossly less efficient than current HVAC systems that are available at similar or less of the cost. In this blog, we will focus on HVAC office design for multi-story buildings and compare some common systems that are designed and installed. The most popularly used three we will focus on are Self-Contained Water-Cooled Unitary Devices (SWUDs) with Cooling Tower, Chilled Water Air Handling Units (AHUs) with Air-Cooled Chiller, and Water-Cooled VRF/VRV with Cooling Tower. I hope this blog will help you make the most efficient decisions for your office designs, your client’s money, and Mother Earth.

Fire Ratings: Do You Need One?

This blog will attempt to answer the age-old question “Does this electrical room need to be fire rated?”.  Well, we are here to clear the air with an emphatic….maybe. Electrical rooms in and of themselves do not require fire ratings because they are labeled “electrical room” but may need to have rated partitions depending on the type of equipment contained therein or the ratings of the adjacent spaces.

The Innerworkings of LEED Certifications as an MEP Engineer

What is LEED certification and why do we as engineers pursue it? As seen in Figure 1, LEED-certified buildings are constructed to be energy efficient, sustainable designs with lower operating costs and waste. The LEED system provides you with a framework to achieve an overall healthy design that benefits people and the environment.
