Less Steam, Please: Thermal Power Reduction In Health Care

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.
Carl C. Schultz, P.E.
July 1, 2016

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.

Adiabatic Cooling Of Data Centers

Carl C. Schultz, P.E.
August 1, 2012
Data center HVAC has come a long way since ’80s-era strategies and even since turn-of-the-century room parameters. Consider that evolution, and how options like economizers and evaporative cooling may be more appealing in light of wider environmental envelopes.

ENERGY CONSERVATION IN EXISTING BUILDINGS

Carl C. Schultz, P.E. Scott Gray, LEED AP, LC
October 31, 2011
The building design and construction industry has been guided and encouraged by Federal legislation and private programs to reduce energy consumption in new buildings and major renovations with initiatives such as EPACT 2005 and USGBC’s LEED®. But what about existing buildings not slated for significant capital improvements?

Closing The Cogeneration Gap

Carl C. Schultz, P.E.
June 1, 2010
Hospitals, hospitality, municipalities, and industrial applications may face their best chance in years to save money (and natural resources) with a combined heat and power (CHP) system. From steam turbines that rely on boilers to gas turbines, on to reciprocating engines and fuel cells, the variety of options is as wide as the range of settings where it might make sense. Reacquaint yourself with CHP, including the sidebar’s “small” example that can save over $100,000 per year.

Biomass Boiler Basics

Casey Oldham P.E. Carl C. Schultz, P.E.
December 1, 2009
From the virtues of various fuel types to options for designing your biomass boiler system, consider this the nuts and bolts - the chips and pellets? - of an increasingly popular strategy as it ranges from district steam to radiant floors.

Natural Ventilation Basics

Carl C. Schultz, P.E.
October 1, 2009
Natural ventilation may sound like an unconventional, sustainability-driven idea to some. However, it was the energy-friendly status quo up through the middle of the last century, back when “green buildings” referred to paint color. If you consider traditionally favorable conditions, several design considerations, and control options, you may recognize a future project where natural ventilation is an idea whose time has come again.

Next-Generation Cooling Is Looking Up

Carl C. Schultz, P.E.
May 2, 2007
After becoming an established comfort tool in Europe and Australia, chilled beams are finding their way into North American designs, and they can generate benefits all the way back to the central plant. Learn to discern the two types available, design tips for both, and the ways they coexist with controls, heating, and other building systems. By Carl C. Schultz, P.E.

Engineering For High Altitude

Carl C. Schultz, P.E.
December 1, 2006
The effect of altitude on the performance of HVAC systems and components all comes down to the variable of atmospheric pressure. Below 10,000 ft, this effect is negligible on certain properties of air such as specific heat, thermal conductivity, and viscosity. However, important properties of air, such as density, enthalpy, and dewpoint temperature, are all affected to an extent that influences the way we must engineer our HVAC systems.

Facility Risk Assessments

Carl C. Schultz, P.E.
September 28, 2006
In many projects, and in government facilities in particular, staff must dedicate more time and money to assessing possible threats and risks relating to IAQ and mechanical systems. Then it's a matter of deploying the proper mitigation measures. Look over internal release, external release, and shelter-in-place as response tactics, and review the latest in air cleaning technologies, from particle and sorbent filtration to UV light.

Biological Safety Cabinets

Carl C. Schultz, P.E.
May 31, 2005
The engineering community’s general knowledge of biological safety cabinets was already below that of fume hoods in general, and then the NSF changed the classification of cabinets, only increasing the air of mystery. Nevertheless, the past few years have seen a steady increase in funding for bioresearch – often involving university facilities. With more and more design opportunities involving BSCs, now is the chance to breathe easier by reviewing classification, operation guidelines, and tips for these important devices. By Carl C. Schultz, P.E.
