What is energy efficient, provides home comfort, improves air quality, easy to install, and requires minimal space? The answer is Enerboss, a new technology developed by Nu-Air Ventilation Systems of Nova Scotia. The Enerboss Unit is an integrated heating, hot water, ventilation, and air conditioning system all rolled into a single small unit.

Home heating and air conditioning systems usually consist of three separate pieces of equipment: a furnace/electrical heat and an air conditioning unit, including the related ductwork, baseboard heaters, ventilation fans and electrical cables. All of this can be replaced with the advanced Enerboss system. Connected to the source of hot water, the Enerboss combines a home's heat source, heat recovery ventilation system, and air conditioning into one package.

The Enerboss technology was one of the first progressive mechanical integrated systems developed in the country. It is an advanced air handler with an integrated heat recovery capability. When coupled with a water heater or central boiler, or electrical supply, the Enerboss provides space heating and ventilation, as well as air conditioning. The compact design and simplified duct, water and electrical connections reduce installation costs. The main advantage of the system is its high energy conversion efficiency and small size. The Enerboss uses less space than a conventional oil fired furnace and its motor is more energy efficient than a conventional furnace motor.

The innovative Enerboss system can be used in single dwellings or apartment buildings and condominiums. A popular feature is its functionality for modern day living. By using the Enerboss technology, a developer building a 30-story high-rise would be able to save space equivalent to an extra story of space in a given building.

Nu-Air Ventilation Systems spokesperson Matthew Kimball says partnering with the National Research Council Industrial Research Assistance Program (NRC-IRAP) helped advance their Enerboss technology. NRC-IRAP works with small- and medium-sized Canadian businesses to help them realize their full potential in areas of innovation and technology. With its extensive network of 260 technical advisors from a range of fields in over 100 communities, NRC-IRAP works one-on-one with businesses to help build their technological capabilities.

NRC-IRAP provided technical and financial support to Nu-Air Ventilation Systems for the Enerboss technology. The company was guided by NRC-IRAP advisor Donald MacAulay. Mr. Kimball said: "Don MacAulay was fully engaged from the get-go and immediately devoted his expertise to help advance our Enerboss technology. Don's background in engineering was of great benefit; he was able to immediately grasp the nuts and bolts of the project and offer valuable insight about different approaches. For example, we worked with NRC-IRAP on improving manufacturing efficiency of a part of the Enerboss, called the "core." The challenge is that the part is manufactured by hand, therefore is very time consuming and costly to produce. Don advised on the manufacturing automation possibilities of this part, offering ideas and names of experts in this field. We are currently exploring those possibilities, and foresee automation in the next 24 months. Everyone we worked with at NRC-IRAP provided the necessary expertise to help us achieve our innovation goals."

Nu-Air Ventilation Systems' Enerboss technology was used in the Drake Landing Solar Community project in Okotoks, Alberta in 2005. The Government of Canada green project saw homes in the community built without standard natural gas furnaces and heated solely by warm water circulating through insulated underground pipes of a distinct heating system. Several companies were approached by the federal government to design a green heating/ventilation system for the Okotoks project and the Enerboss technology was selected.

Mr. Kimball said that without NRC-IRAP support in helping the company achieve its technological capability, Nu-Air Ventilations Systems would not have been chosen as an industry partner in the Drake Landing and Solar Community Project, and business may not be growing like it is today. He added: "An entire product line of ventilation systems and accessories evolved from the Okotoks experience; it pushed the needle for us in terms of new technology to employ in our products."

The Enerboss technology is being marketed in Canada and the United States.
