Navy Hospital Completes New Chiller Plant Project

By | Central Plant Design, Chiller Construction

Although Greenland was not involved in the new chiller plant project at the Naval Hospital in Bremerton, WA, an article in Defense Visual Information Distribution Service highlights the benefits of upgrading aging infrastructure. According to the article, the recently completed project reduces costs via new controls, and features a smaller chiller for lighter loads, which nets a 40 percent reduction in cooling demand.

Upgrading Central Plants to Include Uninterrupted Power and Microgrids

By | Central Plant Construction, Central Plant Design

Like a phone’s dial tone, uninterrupted power is often taken for granted until the power goes out and you need it. While power outages are a disruption for many businesses and organizations, for medical centers and clinics power loss can be life-threatening. As facilities age, the industry as a whole is seeing more demands for uninterrupted power in central plant specs. Read More

2018 Hospital Construction Survey Addresses Hurricane Hardening

Designing and building central plants for hospitals is no longer limited to efficient systems with redundancy for critical components.  The lessons learned in Texas and Florida after major hurricanes are leading to changes in design and construction approaches for medical systems and similar environments.

According to the 2018 Hospital Construction Survey, conducted by The American Society for Healthcare Engineering, 89 percent of facilities professionals consider “resiliency” when designing and building new spaces.  Resiliency in construction means structures and components that resist both natural and human caused disasters, and allow for fast recovery after events.

The Importance of Experience and Expertise

A recent article in the UK publication Modern Building Services magazine provides a clear illustration of why experience and expertise is important in utility plant design and construction.  The article describes a project that replaced eight chillers on the roof of a BBC building, which would not be particularly noteworthy – except for the fact that the chillers failed prematurely due to being installed in an area that restricted critical airflow.

Risk Management for Central Plant Systems During Construction

Central utility plant construction involves the installation or modification of mission-critical systems that must continue to perform during buildout.  Boilers, chillers, cooling towers and similar infrastructure can occasionally go off-line for planned maintenance, but certainly not for the extended time periods required in new construction.  Unfortunately, in many cases a new plant must occupy the existing footprint, adding to the planning required and increasing the potential for service interruptions or complications.

Packaged Utility Plants:  Are They Really Plug-And-Play?

By | Central Plant Construction, Central Plant Design, Design-Build Construction, Packaged Utility Plants

Over the past few years, the central utility plant construction industry has experienced increased use of pre-manufactured, or “packaged”, central utility plant strategies.  This factory-built approach to delivering central cooling, heating and power has the potential to positively impact project schedules, costs and quality.

However, there are some misconceptions.  For example, owners and contractors may be tempted to think these packaged solutions are “plug-and-play” – where all the coordination happens before shipment, driven completely by the packaged plant manufacturer.  In that case, on-site field work for assembly, start-up and commissioning is more of an afterthought.

The importance of Design in Central Utility Plant Construction

Commercial construction is a complex endeavor, made even more so when you consider the mechanical systems needed to effectively control large commercial and industrial spaces.  Consider a hospital, or large university dormitory — each has very specific needs for heating, cooling, electricity, water, wastewater and fire suppression systems.  However, the nature of the building’s use significantly changes the construction approach needed.
