Sustainable Cooling

When we think of summertime, images of picnics and outdoor activities come to mind. However, this time of year can also bring extreme heat and humidity throughout many parts of the U.S. and Canada. With temperatures rising beyond 90° F/30° C, building occupants can quickly become uncomfortable—and unproductive--without the proper measures in place.

However, cooling a building can be expensive. In addition to cost, it places extra strain on the power grid—and our natural resources. In the U.S., buildings account for 36 percent of total energy use and 65 percent of electricity consumption, according to the Environmental Protection Agency (EPA).

To offer relief from the heat, Jaga has introduced sustainable cooling systems to its existing line of sustainable heating solutions . These units work off of hydronic systems and offer a smaller, quieter and more energy-efficient solution in comparison to the forced air systems prevalent in many buildings. In addition, Jaga’s hydronic cooling systems work in conjunction with renewable energy sources, such as geothermal or solar technology, making them an ideal solution for projects focused on energy efficiency.

Different Regions, Different Options

To accommodate the wide variety of climates located throughout North America, Jaga offers two types of cooling systems – sensible cooling and air conditioning. Sensible cooling systems lower temperatures through natural convection principles. The Low-H20 system dispenses cold air through its aluminum Low-H20 heat exchanger.  When chilled water is piped through Jaga’s Low-H2O exchangers, cold air is pushed into the room using Jaga’s Dynamic Boost Effect (DBE) Pro fans. The DBE fan unit clips directly onto the cooling element, completely safe and hidden from view – increasing the efficiency of the system and helping to quietly circulate air around the room. Whilst the DBE unit maintains rapid, effective and accurate room comfort conditions, it can also supply a quick boost cold air if required. This is an ideal solution for areas such as Alberta or New Mexico, where climates are dry and humidity is not an issue.

With sensible cooling the water temperature has to stay above dew point as there are no condensing handling capabilities within the units. Sensible cooling refreshes the room, but doesn’t provide any dehumidification; therefore, it is an ideal cooling solution for dryer climates.

To air condition indoor spaces in more humid climates, Jaga offers the Clima Canal and Briza hybrid solutions. These units substantially reduce the amount of energy used by the system – by as much as 90 percent compared to forced air systems.  Once again, chilled water is piped to the units and an ultra efficient tangential  fan with an EC Motor pushes the cooler air into the space.

Both the Clima Canal and the Briza dehumidify as they can handle condensate. Much higher powered cooling is available in a very small package at a significantly lower energy cost. No noisy compressor, no high utility bills, no unsightly box against a wall, just comfortable cooling!

With Oxygen from Jaga, users can ventilate during periods where the outside air temperature is lower than the inside temperature of the building (night time), using only minimal amounts of energy to run the EC motors.

Additional features of Jaga’s cooling technology include:

1. Extra Space. Forced air systems require extensive ductwork throughout the building, which means extra space. With Jagas system, as ductwork is eliminated, extra ceiling space is gained--up to one additional foot per floor. This gives architects and engineers the opportunity to add additional floors or penthouse suites in high-rise constructions compared to buildings using conventional force air systems. By choosing a hydronic heating and cooling solution, it is possible to  generate additional and unanticipated revenue from extra suites within the same vertical footprint.
2. Noise reduction. Many of today’s heating and cooling systems generate a loud buzzing noise, which can be distracting to workers and building occupants. American National Standards Institute (ANSI) standards (S12.60-2002) require fan coil equipment to maintain hourly averages below 35dBa. Jaga product greatly exceeds this standard, running  below 29dBa (comparable to the sound of a desktop computer fan), helping reduce noise levels and maintain productivity.
3. Improved comfort. Jaga’s systems can be equipped with individual climate control units, where building occupants can set the unit to their preferred temperature rather than having a single thermostat control the temperature for every unit on a floor. This allows for more personalized control of temperature within a building occupant’s space.  In addition, Jaga’s Dynamic Boost Effect (DBE) technology allows temperature to adjust quickly and efficiently.
4. Better indoor air quality. Building ductwork can be a magnet for bacteria and dust if not regularly cleaned and maintained. Jaga’s systems help promote healthy, clean indoor air by eliminating opportunities for these materials to collect in a building’s ventilation system.
5. Lower total cost of ownership. Largely constructed from renewable resources such as aluminum, Jaga’s low-H20 systems reduce the overall heating and cooling costs over the lifespan of the building.

For too long, the argument against hydronic systems was that they didn’t offer true cooling capabilities. Jaga now has the solution, providing multiple options for any North American climate, while staying true to its core values of respecting nature and dreaming a future. By substantially reducing energy use, employing sustainable materials and working in conjunction with renewable energy sources, Jaga’s systems provide a premium solution that keeps occupants healthy and comfortable while substantially reducing the carbon footprint of our buildings.
