Designing a new high school to be 40% more efficient than ASHRAE 90.1 – 2001 energy requirements is a feat in itself. To achieve this degree of efficiency on a very limited capital budget while designing a state-of-the-art, energy-demanding technical high school is an even greater feat.
Energy efficiency and historic preservation are rarely synonymous. More often than not, one must be compromised for the sake of the other. Fortunately, the University of Arkansas found a way around such compromises when it came to the restoration and mechanical renovation of the school’s beloved Peabody Hall.
Effective building envelope and air handling designs took comfort most of the way from theory to reality in ISU’s Hach Hall. An existing in-house deionized water supply and a new fogging system finished the task and saved an estimated 22% in humidification costs.
This past March, I asked the question, “Do you have a corporate sustainability plan?” and recently I was discussing this topic with a director of a physical plant for a major college on the East Coast. He commented, “Energy conservation and environmental management should be a team effort.”
“Not enough airflow.”
These were just a few of the countless complaints that facilities managers of the Basic Medical Science Building at the University of New Mexico were receiving on a regular basis.
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.
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.
Whether your client has a school or office building, desiccant dehumidification can successfully control the project’s humidity, save energy, and remove pollutants. This primer empowers you to teach your clients how desiccants work, while other tips and applications can help your future projects more than make the grade.
Here’s a task: bridge the new mechanical room to the utility connection in the old space - located in an adjacent building in Chicago’s South Loop. Room for equipment is frequently tight, but in the case of this steam pipe, the room for error was less than one inch. The kind of planning that navigated that challenge accounted for (almost) everything in this tricky retrofit.
The first university cogen plant in the U.S. to
Platinum certification, the OSU Energy Center succeeded via consistently
efficiency-minded design and an exceptional level of analysis and teamwork in
the commissioning process. Fuel flexibility, staff training, and a projected
$650,000 annual savings didn’t hurt, either.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
