Project Overview Ottawa Library of Parliament, Ottawa, Ontario This project is a retrofit of a national historic building. The security requirements and maintaining control of the environment during the delivery phase is particularly challenging. The VCI CONTROLS ENVISION system is utilized to monitor and control over 930 points including roof moisture detection and is networked with the existing Parliament Hill VCI CONTROLS system.

Project Overview Completed in March-2013 the Calgary Airport geoexchange system is the largest installation in Canada. The project objectives included the supply and installation of a vertical ground loop system, four thermal conductivity tests and technical design review and support. The ground loop installation includes over 530,000 feet (164km) of vertical ground loop piping, over 200,000 feet (60km) of horizontal tie-in piping and over 265,000 feet (82km) of vertical drilling. The project was broken down into two phases, the International terminal and piers. Each phase consists of multiple mechanical rooms which have mechanical headers collecting the supply/return lines from the vertical ground loop heat exchanger. Two thermal conductivity tests were also completed per phase and an engineering analysis report was completed for each test and provided to the client. Solution The main challenges were following the excavation team and staying ahead of the forming team. It was critical that the vertical wells were drilled on schedule which allowed access for our horizontal tie-in team to follow in behind. By incorporating a central pre-built header system for each circuit it allowed the installation time for the field headers to be virtually cut in half. Spray Foam insulation technology was also utilized to provide a much better quality product and ensure all piping was fully enclosed and protected with an increased “R” value. By using Spray Foam it also enabled us to backfill at a much earlier stage thus speeding up the schedule.

Project Overview Quebec Montreal Châpiteau des arts du cirque, Montréal, Québec The main system includes an underground tunnel for heating or cooling the fresh air, reclaim coils, hot and cold water coil and an ice bank to meet the cooling needs in the performance hall. The implementation of the BAS system was especially challenging as it had to meet low energy consumption requirements. This included dealing with both demanding sun loads of large glass areas combined with large groups of people who are constantly are on the move. In addition excessive noise was a concern and low velocity volume control ensured comfort while maintaining minimal background interference.

Project Overview WestJet new Calgary Campus in Alberta, built in 2008 was envisioned to be a LEED Gold Standard Building. “Our geoexchange system was a key technology in qualifying our Calgary Campus for LEED®gold. Geoexchange has also allowed WestJet to reduce its greenhouse gas footprint by 1,250 tonnes per year.” - Sean Durfy, Past President & CEO Solution CleanEnergy consulted the mechanical design team on hybrid geoexchange systems of 545 tons. The system was designed to back-up the entire heating and cooling load of the building as failures were unacceptable. CleanEnergy incorporated an innovative design solution by putting portion of the geoexchange piping in the building piles. This not only resulted in savings in the earth drilling but also reduced further the risk of any leaks to the ground. WestJet benefited from geoexchange –both on its bottom line and its carbon footprint a 35% energy consumption reduction.

Project Overview Haldimand Motors in the largest used car dealership in North America. It’s new facility in Cayuga, Ontario, built in 2009 has 64 bay shop and incorporated geoexchange system. “I am very very pleased. The cost of running the building is very reasonable and CleanEnergy’s geoexchange system is going to really benefit us. -John Edelman, Owner, Haldimand Motors Solution CleanEnergyTM provided a turnkey geoexchange system for providing Haldimand motors with heating in the winter and air conditioning in the summer. CleanEnergy’s scope of work included design of the 42 ton horizontal ground loop in the field behind the building. CleanEnergy build the system by installing the ground loops, flushing and filling them in an anti-freeze and headers leading to the mechanical room. Heat-pumps used in the project were also supplied by CleanEnergy.

Project Overview In 2005 the Banff Upper Hot Springs needed additional natural heating for its pool as well as domestic hot water and space heating for the structure. The unique thermal system was awarded Building of the Year Award for a Special Purpose Facility under 100,000 sq ft by Building Owners and Managers Association (BOMA) Solutions The natural geothermal hot springs fluctuate in flow volume and temperature throughout the year, causing high operating costs and sometimes pool closures. This project combined the benefits of the existing natural geothermal energy with heat pump technologies. This was a creative way to maximize the use of the natural spring water, all while decreasing the operating costs of the pool. It also served to reduce onsite greenhouse gas emissions from the facility. The system was also designed to recover the heat energy that had previously been dissipated during the pool spring water turnover. The energy is returned to the pool, thereby reducing the amount of additional heat required. In addition to providing heat for the pool, it can also provide the space heating and cooling for the building, as well as its domestic hot water needs.

Project Overview InVue Condominium is a cruise ship inspired 14-storey structure is located in Kelowna, BC. The promoters of the project wanted an environmentally friendly solution to their heating cooling and domestic hot water to keep its residents comfortable all year round. Solutions CleanEnergyTM designed and engineered an open loop geoexhcnage system including the interior mechanical system that included construction ready drawings and specification for pool and hot tub, engineering heat loss and gain calculations, geothermal sizing and tenant fit-up drawings. In an open loop system (also called a groundwater heat pump), the secondary loop pumps natural water from a well or body of water into a heat exchanger inside the heat pump. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate injection well completely safe and free of any chemicals. Care was taken to place the supply and return lines far enough apart to ensure thermal recharge of the source. Each unit in the condominium is supplied with fan-coils to provide for its own heating and cooling. Domestic hot water is preheated using heat-pumps.
