HVAC Design/Construction Process

This month’s Facility File will focus on the B2B June test for a heating application on a college campus, with a building program removing a dormitory heating system from the campus high-pressure steam system and replacing it with a high-efficiency condensing hot water boiler within the dormitory.

A new line of dedicated outside air systems (DOAS) from the YORK® brand of Johnson Controls includes a range of 100% outside air units and mixed air units. With heat pump operation and water source operation, as well as a hot water heat option, the new line of air systems delivers more combinations of heating and cooling. The systems also feature an internal energy recovery wheel that pre-conditions outside air and reduces heating and cooling loads by transferring energy between the exhaust airstreams.

Air distribution in a space and diffuser selection is simple, right?

Waste heat recovery innovation doesn’t make the news that often, so when it does, I have to wonder whether you, clever reader, can steer that innovation toward some creative advancements for the HVAC industry.

Over the years of designing and building HVAC infrastructure, I’ve been fortunate to be able to complete the projects via integrated project delivery (IPD) and design-build (D-B), in addition to design-bid-build (DBB) and construction management (CM).

For those who design in BIM/CAD, manufacturer-provided content is widely viewed as being superior to generic, out-of-the box content when planning and designing a project.

Our objective in specifying motors for HVACR equipment is to start and run the driven equipment under all operating conditions reliably and with reasonable life expectancy.

This month’s Facility File will focus on the B2B March test for an existing three-story private office building energy retrofit.

Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.
