In today's business climate innovative and creative problem solving is more important than ever. Environmental concerns, as well as questions about cost, serviceability and general performance factor prominently in the decisions architects, engineers and building owners make when considering an HVAC system.

Here are just a few of the results-oriented solutions Trumbull Campbell Associates has developed for our customers.

Case Study:
South High Community School, Worcester, Massachusetts and AAON

In today's charged economic and political climate there are times when what's good for students, the environment and the bottom line are at odds. But sometimes, they are one-in-the-same.

The Worcester School District was facing a problem playing out in conference and committee rooms all over the Commonwealth, and all over the country: How to maintain the long-term viability of a capital asset while not breaking the budget.

The South High Community School, built in the 1970s was in desperate need of an HVAC upgrade. The existing system, dating back to the school's construction, was an outdated multi-zone rooftop unit that left classrooms too cool in the winter and too warm in the spring and fall.

Not only was this inefficient system making the classrooms uncomfortable, but it was also leading to higher utility bills. To complicate matters, any new system would need to utilize the school's existing roof curbs and duct work.

After meeting with the Worcester School District, Trumbull Campbell Associates reviewed their needs and the specific nature of the application. To meet these needs the team at Trumbull Campbell Associates recommended packaged DX/gas Aaon energy recovery units with variable frequency drives and modulating gas heat. The Aaon units allowed them to recover heat and cooling from the energy recovery wheels, reducing the cooling tonnage and gas consumption required to heat and cool the space-and cutting utility bills.

The Airxchange energy recovery wheels were calculated to save approximately $1.2 million in today's dollars over the average life of the new rooftop units. For roughly the same price as a larger more energy intensive rooftop unit, Trumbull Campbell Associates and Aaon can provide the same amount of work with a smaller, wheel based unit that performs with over 40% increase in efficiency. This translates to significant energy savings over the life of the equipment.

The AAON system recommended by Trumbull Campbell Associates-an environmental as well as technological upgrade over the legacy system it replaced-allowed the School District to cut costs while providing a safe, healthy and comfortable environment for teachers and students.

Case Study:
Lockheed Martin and ClimateCraft

Aircraft development and engineering is a precision industry. The smallest flaw can have a disastrous effect, especially when working on experimental avionics and other sensitive systems. In this fast-paced and often-stressful work environment, the last thing anyone on a development team wants to worry about is the environment in which they work.

HVAC systems are important parts of any modern manufacturing plant, but when that plant is fabricating components for the Department of Defense or the National Aeronautics and Space Administration it can be even more mission-critical. When dealing with explosives, chemicals and other extremely hazardous compounds, environmental control cannot be left to sub-par or cut-rate systems.

That's why when Lockheed Martin, one of the world's largest defense, aerospace, global security and advanced technology companies was looking for an HVAC system for one of their facilities, they opted to work with Trumbull Campbell Associates to choose their solution.

For the organization that developed and built the innovative F-22 Raptor and F-35 Lightning II fighters Trumbull Campbell Associates selected ClimateCraft, an HVAC system provider with a history of developing high-tech and cutting edge products through an advanced manufacturing processes. By leveraging our experience and ClimateCraft's unique approach, we found a dynamic solution for one of the United States' truly dynamic companies.

Case Study:
Jordan Hall, New England Conservatory of Music

In the controlled environment of a concert hall sound quality and environmental control are of the utmost importance.

The New England Conservatory of Music had a set of very specific requirements that needed to be met when installing a new HVAC system. Temperature and humidity can affect musical instruments, throwing them out of tune more easily, even potentially causing damage through swelling and cracking. Also, the comfort of the musicians, performers and audience needed to be taken into account as did the ambient noise level in a large open space used for broadcast-quality recordings.

Additionally, the structure itself-built in 1903 and modeled after an Italian renaissance palace by architect Edmund Wheelwright-presented other challenges. Known for its unique horseshoe shape and steeply graduated floor that contribute to its outstanding acoustic properties, Jordan Hall is regarded to be one of the world's top concert halls for classical music.

When the New England Conservatory of music needed an HVAC solution, they chose Trumbull Campbell Associates-and Trumbull Campbell Associates chose Smardt. Thanks to the superior performance and uniquely quiet operating volume of the Smardt Chiller recommended by Trumbull Campbell Associates, the only thing heard in Jordan Hall is the music.
