“The awards communicate innovative systems design to other ASHRAE members and highlight technological achievements of ASHRAE to others around the world,” said the association.

Gheorghe Mihalache, engineering director of Atis Technologies receives first place in the existing industrial facilities or processes category. The cheese factory, along with the five other winning projects, will receive their award next week at the ASHRAE 2014 Winter Conference in New York, N.Y.

Founded in 1994, the factory produces an annual milk transformation of about 3 million litres and its energy sources are oil #2 and electricity.

In 2010, a mechanical project was developed to:

• Minimize all necessary energy for the production;
• Change the heating and refrigeration of the site;
• Construct a digester to produce biogas from the plant rejections (whey and white waters) and use the biogas in the production and buildings heating;
• Add ventilation (100% fresh air) in the cheese production area to ensure a positive pressure and correspond to Canadian Food Inspection Agency regulations; and
• Change the High Temperature Short Time to be able to preheat the milk in the pasteurization using the refrigeration heat reject.

An existing warehouse was transformed in a mechanical room for the heating, refrigeration and digester infrastructure, and a new building was constructed for the effluent post treatment.
