Commercial HVAC
Using free solar heat significantly reduces power consumption and can eliminate water heating expense all together in some applications.
Heat is inexpensive to collect and easy to store in tanks. Water, salt brine, peanut oil, and many other substances may be used, such as Phase Change Materials. PCM holds great amounts of heat as solar energy changes its phase from a solid to a liquid. When heat is taken out of the system, PCM changes back to solid phase and releases the same amount of stored energy. With a properly balanced heat collection and storage system, the energy collected during the summer will keep your customers and employees warm all through the winter months with reduced conventional heat.
Efficient radiators circulate the air using low power pumps and fans, which can be powered with solar panels, making your HVAC system impervious to power interruptions and free to operate.
Radiant cooling removes heat from the work space, thereby cooling the area. Circulation fans keep the air moving and insure even temperature. Coolant transfers the heat to a sink like a pond, a rain garden, or underground cooling coils. A cold storage tank with PCM may also be utilized as a buffer, which could be chilled during the winter months.
Solar heat and heat recovery technology can be used with standard HVAC systems to increase efficiency and reduce the size HVAC system required.
Outside (fresh) air can be precooled or preheated with an exhaust air heat recovery system. A heat exchanger built into the air handler utilizes exhaust air to preheat/precool fresh air to minimize power consumption.
These are just a few examples of the many energy savings strategies available to businesses.
Be the change. Go green!
Evolution is Profit Driven--The Bottom Line
 |
Heat collection and storage systems are inexpensive. They average a more than 50% savings on water heating costs, can be used to heat spaces in the winter, and are easy to maintain. |
| Insulated storage tanks come in many shapes and sizes. Storage tanks are like batteries, storing heat energy during the day. Large tanks can store vast amounts of energy. Phase change material stores heat even more efficiently. |  |

Radiant heat is usually installed in flooring systems during construction. Retrofit heating includes baseboard heaters and freestanding radiators with low power fans. |
| Cooling radiators can be retrofitted to almost any work space, above drop ceilings, inside work station partitions, crown molding radiators, or free standing radiators. Even if geoCooling is unable to satisfy 100% of your needs, this system will significantly reduce loads on conventional HVAC systems. |  |
 |
HVAC radiators installed in floors and ceilings cut energy costs by half or more. A properly designed system should equal the effectiveness of traditional high powered air handlers in all but the heat of the summer months. |
| During the winter, radiant heat warms the space from the ground up, so that heat remains where the people are working, rather than forced air--all the heat goes to the ceiling. In summer, heat is removed from the ceilings--where it is concentrated most. |  |
 |
Heat gain is more important than heat loss, for most businesses. Reflective roofing materials, shades on windows, reflector plates, grills, attic ventilation, ducting insulation, low e insulated glass, and venting of appliances and computer equipment may help reduce your overall cooling costs. |
