D-B and IPD My Way -- Part 2

A successfully coordinated team effort can drive repeat business.

June 5, 2017

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.

New Boiler System To Replace District Steam For Existing Dormitory

For Existing Dormitory Using Integrated Project Delivery

Amanda Parolise

June 1, 2017

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.

York DOAS – Johnson Controls

May 22, 2017

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.

QCC2 and QCC3 condensing units -- Quantech

May 22, 2017

Quantech™ has added QCC2 and QCC3 air-cooled, scroll-compressor condensing units for applications ranging from 15 to 160 tons to its portfolio of ready-to-ship products. The condensing units are designed for pairing with indoor air handlers using direct expansion (DX) evaporator coils. Quantech QDC condensers and QDCF fluid coolers are also available for air conditioning and refrigeration applications as high as 2,890 MBH.

State Of Diffusion: Have Typical Air Distribution Design Habits Gone Stale?

After decades of the old terminal velocity standby, it may be time to do away with “We’ve always done it that way.”

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

Better Living Through Chemistry

Can a new compound translate to HVAC?

Robert Beverly

May 7, 2017

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.

D-B and IPD My Way -- Part 1

Some project delivery takes a village — and that’s a good thing.

Howard McKew, P.E., C.P.E.

May 1, 2017

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).

Quality BIM/CAD Content For PEX Piping Systems

For years, architects have benefited from having readily available manufacturer content at their fingertips. Now it’s time for MEP engineers to start experiencing the same benefits, especially when it comes to designing with crosslinked polyethylene pipe.

Mike Rivers, CPD

April 2, 2017

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.

Terms Of Service: Motor Fundamentals

In the first of a pair of articles on motor fundamentals for HVACR, the author gets into everything from industry standards and service conditions to changing speeds, enclosures, and the often misunderstood service factor. You’ll want to save this one for your team’s reference library.
