Encotech Wins 2014 ACEC Engineering Excellence Award

April 04, 2014

Encotech Engineering Consultants' work on the Zach Topfer Theater has been awarded the Gold Medal - Small Firm in the 2014 Engineering Excellence Awards from the American Council of Engineering Companies of Texas.

Encotech faced the challenge of creating a HVAC system that could cool a 26,195 square foot, 420 seat space in the middle of a Texas summer, while doing so silently and energy efficiently.  The Displacement Air Distribution system met and exceeded the challenge. 

The space underneath the seating in the theatre acts as an air tunnel and slowly releases air into the theatre from vents located below the seats.  The cool supply air (55°F) from two packaged roof top units partially mixes with filtered return air and is tempered to 65°-68°F while in the plenum.  The air naturally rises up heat sources (such as seated patrons) and all the way to return grilles mounted high at the back of the auditorium.  A displacement system from the floor provides these benefits:

only cools the space around occupants
eliminates drafts/ provides even temperatures throughout seating area
removes contaminants to the upper return, providing healthier indoor air conditions 

Displacement ventilation is a new method of conditioning spaces developed by Price Industries.   This application of floor registers in the risers of a concrete auditorium structure is unique.  

We are very proud of our Chief MEP Engineer, David Mitchell, P.E., who was responsible for this innovative design. Ali Khataw, P.E. – CEO, and Kristine Bryant – Marketing Manager, attended the award banquet in Dallas on March 28th, 2014 to accept the award
