HVAC Design/Construction Process

RSS

Quite often, design engineers choose decentralized HVAC systems because of first-cost benefit, packaged equipment, simplicity of design, and the repetitiveness of the installation, to mention just a few of the features.

Understand the thinking behind a system that blends condensing and non-condensing boilers, from the attack on oversizing to a controls strategy that shifts with the weather.

More than 17 billion feet of PEX, or crosslinked polyethylene, has been installed worldwide. That’s enough to stretch to the moon and back almost seven times.

When every project and system is unique, there may not be a “correct” time.

Commercial kitchen ventilation (CKV) has been a challenge to mechanical engineers for years. Part of the challenge comes from the fact that the mechanical engineer is normally not the “kitchen consultant.

This month’s B2B will focus on a new 12-story patient tower located at a health care campus.  This month’s test will address the design intent of an engineered zoned smoke control of return air, supply air, and exhaust air system serving the patient floor common corridors.

In the commissioning specification, the owner made the general contractor responsible for the cost of retesting required due to deficiencies discovered during initial functional performance testing.

Can I get a big, “THANK YOU?” I’d like to start the New Year on a positive note since I’m a person who always looks at the “glass half full.”

Commissioning is far from being “business as usual” in the design and construction world. I was reminded of this fact recently when a building owner expressed the expectation that the commissioning professional would be responsible for subcontractor coordination, workflow planning, and installation start-up scheduling.

This month’s B2B will focus on the renovation of the office space (not part of B2B test) and replacement of the building’s existing baseboard radiation to new overhead radiant heat panels to be installed in the ceiling around the perimeter of the single-story 40,000-sq-ft building.
