Using data trend logs to supplement in-field functional performance testing (FPT) has always been an option in the commissioning process, particularly for HVAC systems controlled by DDC systems. As DDC system trending capabilities and computer hardware storage capacities have improved substantially over the past few years, I propose that trend logs be given a more prominent place in the commissioning toolbox.
With the help of advances in intelligent controls and a shift in design mindset, these systems can steer buildings toward smaller equipment sizes and associated savings. Review three projects and consider the benefits of keeping an upcoming project in the loop.
As I read the press release, something about the DOE’s planned user test bed facility at Lawrence Berkeley National Lab reminded me of the old Wendy’s commercial from the ’80s that most of you are, uh, mature enough to recall.
In this overview of building information modeling, the authors review how BIM helped in three different projects, often with particular usage- and efficiency-based HVAC demands. While BIM’s space management skills can reduce costly changeorders and building design “clashes” ahead of time, in at least one instance, using BIM actually influenced the HVAC strategy for the better, too. See how HGA Architects and Engineers has used this to become a “model” firm.
Here, our long-time forward-thinking columnist uses a common hospital scenario to walk you through the shift from Design-Bid-Build to an Integrated Project Delivery approach. See how the job can get done with similar personnel on a considerably shorter schedule, resulting in a greater team investment in the project’s success and yet more time to get on to other work.
Some thermal storage media are familiar to most
of us, but what about gravel? Or lake water? See how those can work in the
right environments, and tuck this away as a general refresher on thermal
storage concepts and options for use in hospitals, data centers, and elsewhere.
