Millies Engineering Group

Millies Engineering Group, working with JMA Architects, successfully completed a mechanical systems upgrade on 43,000 square foot Wolcott Jr. High School in Thornton, Illinois. The project consisted of removing and replacing standard efficiency gas fired water heating boilers and domestic water heaters with high efficiency systems. The existing boilers and water heaters were past the end of their expected operational life and the Owner had a desire to upgrade to energy efficient systems. Also, the existing domestic hot water heating system could not keep up with current demand.

To meet the Owner’s requirements, MEG implemented the following design concepts:

  1. Replacement of one existing standard efficiency (80%) hot water heating boiler with two high efficiency (93%) condensing boilers with variable speed drives on distribution pumps to improve energy efficiency. The hot water distribution system is designed to vary the supply water temperature based upon outside air temperature. This allows for the supply water to be as low as possible, while still maintaining space temperatures. By keeping the supply water temperature low, we are able to increase boiler efficiency (condensation of flue gasses) for longer periods of time.
  2. Replacement of two standard efficiency, natural draft domestic hot water heaters with three continuous flow gas fired domestic water heaters. The continuous flow water heaters do not “store” hot water in a tank, but provide hot water on demand. By removing the need to heat the “stored” water in the tank, the continuous flow water heaters save energy by reducing gas consumption. The Owner has received no complaints regarding domestic hot water in nearly two years of operation.


It is anticipated that these energy efficiency items will help the building perform between 20% and 25% better than the previous systems. This additional energy efficiency is achieved with only a minimal increase in construction costs.

On-Site Power Generation
Incorporating a photovoltaic system to produce energy is one of the growing sustainable design options that can also allow training and educational opportunities
...READ MORE

Millies Engineering Group

Millies Engineering Group was contracted to design the mechanical, electrical, plumbing and fire protection systems for the New INTAC Local 697 Center located in Merrillville, Indiana. As part of our services, we designed a new roof mounted photovoltaic system.

A photovoltaic system utilizes an array of cells that contain solar photovoltaic material that converts solar radiation into direct current electricity. The direct current electricity is then converted to alternating current electricity by an inverter. This allows the electricity to be fed into the building’s electrical grid and provide a portion of the electricity required for the building. The system at IBEW 697 is capable of producing 21.5 kilowatts (KW) of electricity which provides approximately 40% of the building lighting load.

This photovoltaic system consists of 96 mono-crystalline silicon solar cells each capable of producing 224 watts of electricity. The solar cells are manufactured by Sharp and are made in the USA. These solar cells are divided into two sets of 48 cell arrays, which are mounted on two different roof sections. Each 48 cell array supplies one of two Fronius #12.0-3 direct current to alternating current inverters. This inverter has a DC to AC conversion efficiency of 96%, making it one of the highest efficiency inverters in the industry.

The Fronius Datalogger is incorporated into this system, giving the capability of monitoring the system from anywhere in the world via the internet. The solar cell arrays are roof mounted on a steel mounting structure manufactured by Silverback. This mounting structure consists primarily of Allied Tube products, which are also made in America from regionally produced American steel. The installation and project have been a great success, and have been utilized for training with new apprentice electricians.

Our firm has been designing sustainable solutions for years, including those which have utilized renewable energy components within the design. For example, Centennial Park, located in Munster, Indiana was provided with methane turbines, which burned methane gas reclaimed from the decommissioned landfill the park was built on. Also, two new elementary schools located in Markham and Hazel Crest, IL, are currently under construction with roof mounted photovoltaic arrays to provide on-site renewable energy, as well as an educational opportunity for the students when completed in the Fall of 2014.
