We’re all familiar with the term “sick building”. Sick buildings generally result from one of several factors, which have their root primarily in less than standard outdoor air ventilation (and therefore inadequate air changes in the building spaces). This in turn can lead to high carbon dioxide content in the air being breathed by building occupants, recirculation of air bourn contaminants, and growths of molds and spores in the building ductwork. Interestingly, much of the time these problems weren’t inherent in the original building design, but became problems due to either an improperly operating control system, disconnecting and closing outdoor air damper controls due to concerns over high energy costs, or nuisance low temperature safety trips. As is often the case, treating the symptom and not the disease can ultimately have a high long-term cost!
Tri-M can provide proven solutions to this problem, which include monitoring and control of outdoor make-up air, and monitoring of building carbon dioxide levels to provide precise control of outdoor air makeup volume. This balances the need for proper ventilation with the need to keep energy costs at a minimum.

T.A.C. Energy Management

“Energy Management Systems” is generally considered an obsolete term from the early 1980’s, when DDC/BAS was evolving out of the need for energy savings (which had been spurred in the 1970’s by the energy crisis). However, today’s Building Automation Systems have a tremendous potential as an energy savings vehicle, due to the fact that the BAS connects to many of a facility’s primary energy consuming loads (rooftop units, chillers, boilers, lighting, etc.).
Tri-M has a track record dating back to the 1980’s of providing detailed energy analyses in order to make recommendations for lowering energy costs, and then implementing controls solutions to meet those cost reduction goals. Andover ’s hardware and software flexibility allow us to implement literally any type of energy savings strategy required. We have a number of successes over the years, with proven strategies for saving energy. Call us for a free, no obligation consultation to determine how we can help you lower your energy costs.

T.A.C. Lighting Controls

Facility lighting control has grown to new heights of sophistication in recent years. New developments include automated breakers and dimming systems, indoor light level monitoring, automation of outdoor lighting via photocells, and more. This lighting control can now be integrated with building schedules and/or card access via the Andover Controls system to provide precise lighting control in terms of both usage and intensity, resulting in the lowest possible energy usage for lighting. For example, an employee enters the building by swiping his/her proximity card at the front door. The Andover Control system recognizes the employee’s card, and immediately turns on his/her office light and air conditioning for his office (and perhaps even the coffee pot). This is a simple example of the power inherent in today’s Andover technology.
