Anoka-Hennepin Schools Building Automation System

SCHOOLS OUTFITTED WITH THE LATEST IN BUILDING TECHNOLOGY

PROJECT:

LOCATION:

Blaine and Ramsey, Minn.

BUILDING TYPE:

Education

EGAN EXPERTISE:

Building Automation / Controls

PROJECT TEAM:

ATS&R

PROJECT FACTS:

Design and installation of new building automation systems with new HVAC systems and latest generation automation hardware. // Egan took on this unique “parallel-project” and approached it with separate crews; while there were challenges with coordination efforts amongst varying contractors and personnel at each level, the delivery and outcome was twin installations (a success for the schools!).

SPECIALTIES FEATURED WITH THIS PROJECT:

Building Technology Integration, Building Automation Engineering and Software, Building Automation Electrical Installation

Anoka-Hennepin Schools completed the construction of two (2) new elementary schools within the district in 2019.
As a long-standing contractor partner with the district, Egan’s automation team worked on both elementary school projects, simultaneously, with the goal of building identical-as-possible installations.
Working closely with ATS&R, the design and engineering firm for the project, the design utilized interesting HVAC applications:
-Heating Plant
-Chiller System with primary, secondary cooling and tertiary terminal unit cooling water control
-Dedicated Outdoor Air Systems, Variable Air Volume Systems, Single Zone Systems for -various air delivery needs
-Chilled Beam Terminal Units with 6-way control valves mixing cooled and warm water -as required for space conditions
-Displacement Induction Units
-Lighting System Integration
-Variable Refrigerant Flow System installation and integration
-Utility metering
Utilizing the latest generation, fully programmable Cylon-Automatrix (ABB) Building Automation Systems controllers, new software strategies were developed on a new platform for this project’s unique systems.
The Chilled Beam is a terminal unit, located in the occupied space ceiling that takes warming air from the space, mixes it with fresh air from a traditional supply duct and passes that air over a cooling coil located in the ceiling. The result is: quiet, reduced fan energy, and efficient.
Chilled Beam System requires integrated control of:
-Central Plant
-Air Handling Delivery with accurate control of air temperature and humidity
