Continuing on from last month’s discussion encouraging design engineers to create their own automatic temperature control (ATC) system flow diagram and write their own sequence of operation, let me start with the importance of this responsibility.
When I first started in the HVAC industry working in a design consulting engineering firm, I came to accept that the HVAC sequence of operation and its associated contract specification, Automatic Temperature Controls (ATC), were provided by an ATC sales engineer.
Last month, I opened a discussion on how I have enjoyed integrated project delivery (IPD) and design-build (D-B) projects over the years and how I have been fortunate to learn from other team members as I shaped my “full team participation” (FTP) process.
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).
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.
How often does an existing closed loop hot water heating or chilled water cooling system get reused as part of a building renovation project, and/or used to expand the area served by the system coverage to provide additional heating or air conditioning?
