| Springdale Professional Building |
|  |
An independent analysis by Caneta Energy confirms that a Hybrid Heat Pump Geothermal System installed in the Springdale Professional Building will result in 23.8% energy savings over a conventional GSHP system.
"Caneta Energy has modeled heat pump systems in a significant number of buildings over the past number of years. We have seldom seen a concept as promising as the CGC Group hybrid system, particularly when used in a ground coupled system with water to water heat pumps between the building loop and ground heat exchanger. When the building is balanced thermally, the ground heat exchanger can be by-passed, to maximize heat recovery and minimize pumping. This provides the benefits of conventional water-loop and ground source concepts in one system."

As the flagship property of the Blue Mountain Intrawest, Village at Blue required a 5 star approach for construction. The integration of the heating and cooling systems had to flow seamlessly through the resort, reflecting a level of environmental as well as economic efficiency that would add to the concept of Village at Blue being a world class resort. The potential energy consumption of the Aquatic Center and large spaces such as the banquet areas presented an opportunity for CGC to show true innovation, as initial project estimates came in above budget. | |
| Yorkville Tower |
|  |
The new Yorkville Tower construction project consists of one 36 storey and one 12 storey residential condominium above one floor of retail space. The Make Up Air requirements for the entire structure are met by CGC Group Varipak units. The original concerns about exceeding the equipment budget were overcome by a step by step analysis of the building. The findings indicated that using traditional heat pumps would demand an increase in the fluid cooler, piping system, pumping stations and primary electrical service. A solution was required that met both the budgetary constraints as well as high environmental and efficiency standards. | | | Sunrise Assisted Living | |  | Emergency Back-up Power The project required a way to ensure heating under a loss of power condition. A back-up generator was required and size of the generator and power distribution were considerations. The advantage of the CGC Group Hybrid Heat Pump System is that the compressor does not operate in heating. The unit functions as a heat recovery air conditioner resulting in compressor operation in cooling only. Heat recovery requires only fan operation. A 24 volt signal is required to lock out the compressor. Reduced Project Electrical Cost The Hybrid Heat Pump System was selected to provide year round heating and air conditioning utilizing a 2-pipe heat recovery loop with an auxiliary boiler and cooling tower. The installation cost is similar to a water source heat pump system, but the energy cost will be reduced by 35 - 40% annually. This project featured hinged access doors with magnetic strips allowing easy filter service. Removal of the access panels reveal service LED's and a sight glass for troubleshooting, but the entire chassis is plug-connected for quick change out in 15 minutes. One spare chassis can serve the entire project. | |
| 360 On Pearl | |  | The Challenge
Modern buildings are often constructed with glass areas and spectacular views but come with comfort challenges. Heating the space near the full height windows becomes expensive and difficult. Often, the result is an almost uninhabitable cold space at the perimeter with cold drafts commonly referred to as "the cold wall effect".
The Solution
ComfortZone by the CGC Group utilizes the warm heat pump fluid loop for radiant in-floor heating as the first stage of heat.
Treating the problem at the source with radiant heat eliminates cold spots and downdrafts, and provides greater comfort. | |
| Le Vistal | |  | In Montréal, Québec, the Le Vistal condominium buildings are located on the tip of L'Ile-des-Sœurs. These 2-25 storey towers were built with the comfort of the residents and eco-friendly practices in mind, so an energy-efficient system was needed. As the buildings were being constructed, CGC supplied ecologically conscious systems and materials such as 330 Hybrid Heat Pumps, 14 Compax Water to Water Heat Pumps, and R-410A refrigerant. The use of these systems allowed Le Vistal to participate in the Green Loan program, whose loans are repaid with the money that energy-smart designs save. Since Le Vistal was designed to achieve LEED certification, these buildings continue to aim for the highest standards in environmental sustainability and efficient operation. | |
| Broad Street Bank | |  | The restoration of this century old skyscraper required an HVAC retrofit. Preserving the historic nature of the building required a system with a small footprint. Low electrical consumption was a priority due to the limitations of the available services, and the need for greater efficiency.
The CGC Hybrid Heat Pump System with its retrofit friendly design proved to be the perfect choice for this historic restoration. The low profile horizontals were concealed in the ceilings and console units were surface mounted with little intrusion on the aesthetic value of the interior. An efficient central heating plant, with the CGC's unique Heat Recovery system, services the entire building. This ultra quiet, super efficient system raised the comfort level of the Broad Street Bank Building, while meeting and exceeding their energy requirements. | |
| Bella Vista Apartments | | | One of the measures of the successful application of advanced HVAC technology is the level of comfort experienced from the system.
