Central Utility Plants
Central Plants | CUP | MEP Central Utility Room
CUPs are complex to design and need unique skills and knowledge from designers. At RWB, one of our specialties is design for central utility plants. That’s why owners across North Texas trust RWB Consulting Engineers to design their central plant.
CUP is an abbreviation for Central Utility Plant. A central utility plant is the epicenter of the mechanical, electrical and sometimes plumbing systems that serve the building or many buildings on a site.
The CUP is home to all major mechanical, electrical, and plumbing equipment. Most equipment that supports the operation of the campus will be at the CUP. Some examples include power, water, and air conditioning equipment. More specifically, the generators, chillers, boilers, main pumps, central receiving, or centralized air compressor or other utility systems.
Many people refer to the CUP as the heart of a building system, while others refer to it as the workhorse. Either way, the CUP is the center point for building systems. It does most, if not all, the work to supply connected buildings.
The purpose of a central utility plant is to create efficiency by grouping utilities and maintenance.
Optimizing the size of equipment is one of the main reasons a central plant makes sense. With a central plant, we can take advantage of shifting loads throughout building(s), and reduce the overall size of the equipment.
A simple way to think of this is three hungry neighbors ordering pizza for dinner. Each neighbor orders their pie, even though they all only want a few slices. Had they combined their orders, the neighbors could have saved money (and reduce leftovers) by ordering just fewer total pizzas. Hungry for lunch yet?
Other reasons to use a central plant include:
While designing a central plant, engineers have many challenges to consider. These may or may not be top-of-mind concern for building owners, depending on how much familiarity they have with MEP central plants. The three main challenges are:
Central plant reliability is a primary concern. Since a CUP serves multiple buildings, it’s critical to ensure that equipment stays up and running. Our team is well-versed in reliability best practices, going beyond simple redundancy. If your central plant is having problems with reliability, don’t hesitate to contact us for a consultation.
The size of the central plant needs to be carefully calculated by designers. From a physical size standpoint, the structure must be able to contain all the equipment plus room to grow. Additionally, the peak and block load from all the buildings must be considered to determine the CUP capacity.
As part of the design process, we determine not only when the peak demand might occur, but how the equipment will respond. Designers must ensure that building systems can handle heavy usage.
Master planning includes complete campus evaluation to determine needs. In many cases, a master plan or feasibility study is completed to determine the future design work required.
RWB has extensive experience in master planning central utility plants. We work with owners and facility managers to identify future growth needs, plan the building and system design for those needs and provide budget estimates.
Because many CUPs have a large amount of floor space, there is flexibility in retrofitting central plants.
There are several reasons that a CUP might require updating, such as the ones listed to the right.
RWB has several clients that we have worked with on CUP retrofits. We are extremely familiar with the design challenges in renovating central plants. We also have experience in evaluating central plants that aren’t working properly, and helping owners troubleshoot these issues. No matter the project, our commitment is the same: 100% customer satisfaction.
