Probably a year before 9/11, I was asked my thoughts along the lines of, “What else should we commission beyond the standard building systems?” My client was the project engineer at the Department of Defense in the Pentagon. I suggested “commission project record drawings.” I guess you could say I made up the task of commissioning record drawings, but I got my point across.
Hospitals in the U.S., already facing daunting challenges from evolving health care reimbursement models, now have another item on their to-do list: prepare for increased health care demands and weather disasters caused by climate change.
A few months ago, this column covered the basics of developing effective control system sequences. You might recall that it discussed the process of how a designer needs to select and describe sequences that provided safe, reliable, and efficient control.
Integrated Project Delivery (IPD) is a collaborative process that has been applied more and more frequently to building design and construction projects. Although it is implemented in slightly different ways from project to project, it is always about involving all project team members in intense planning and coordination, starting very early in design and extending through construction and facility turnover.
This second look at the Museum Of The Bible project focuses on the integrated life safety design approach. The team arrived at a final design that not only provides functionality appropriately tailored to the space but also incorporates itself into architectural elements to preserve aesthetic value. The BAS plays a key role between the mechanical and electrical sides of smoke control as well.
The Museum of the Bible (MOTB) will be a non-sectarian museum focusing on the history and impact of the Bible with a core collection of more than 40,000 biblical antiquities and rare biblical texts and artifacts. The museum will contain a mix of uses, including exhibit space, library resources, meeting spaces and guest rooms for visiting scholars, space for certain affiliated museums and their exhibits, and sound ground floor accessory retail uses, such as a gift shop and café or food service establishment.
More specifically, has natural gas been overlooked? Let’s take a look at some previous habits and code language, current needs, and the advantages that a CHP system can provide for those exceedingly regulated of all environments: hospitals.
Emergency generators are required in many applications where facility operations are to continue to perform even upon a failure of the electric grid. The best resources for quantifying the emergency generation classifications, capacities, installation, maintenance, and operational testing requirements are the building codes and federal regulations.
It might seem like an odd objective, but the potential efficiency gains are real. And from heat recovery chillers to modified humidification targets so are the opportunities to replace steam production with hot water generation and to manage remaining steam needs more intelligently.
The production of thermal power is critically important in carrying out the mission of health care facilities where it is used for space heating, humidification, domestic water heating, and for processes in dietary, laundry, and sterilization departments. The age of the hospital, the programs offered, and the regional climate will all affect the demand for thermal power.
Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
