The Strategy

Air Source Heat Pumps provide effective air conditioning capabilities by transferring heat between bodies of air utilizing temperature differences between inside and out (not energy).

In cooler climates, the Air Source Heat Pumps can be supplemented and coordinated with Electric Resistant Heating Coils which providing the most efficient heat sourceconverting 100% of its delivered energy into heat. When these mechanical systems are powered by solar energywitha battery backup, they operate independently of any electrical grid, or additional fuel source, while meeting its required heating and cooling loads. When the Air Source Heat Pumpis combined with an Energy Recovery Ventilator (ERV), or Heating Recovery Ventilator (HRV) dependent upon climate,the housecan retain between 60%-85% of the latent heat.
  • In mild or hot environments, the system can optimize the use of an ERV transferringlatent heat while extracting moisture to control humidity levelsas it exchanges stale interior air with fresh air
  • In cooler environments, the system can optimize the use of an HRV to retain latent heat in the air as it exchanges stale interior air with fresh exterior air.
Residential clients located in mild to hot climates can optimeize the combined system benefits of a balanced ASHP with cooling and heating loads with an ERV system which transfers heat along with extract moisture to control humidity levele while it exchanges fresh air. Clients located in cooler climates can benefit from an ASHP with a stronger heat load capacity and an HRV system to capturing the heat in the air as it exchanges stale air with fresh air.

Benefits
Our combined systems powered bysolar energy can deliver ahome's heating and cooling load independent of the local electrical grid. Different climates will vary the demand loads, but by adjusting for these changes andusing the correct equipment sizes, homeowners can take advantage of energy efficient homes with healthy indoor environments.
The only cost to the home owner is the front end cost of installation which is quickly recuperated due to the elimination of future energy bills.
Synergies
High performance homes operate with little (or even zero) energy consumption due to well insulated, air tight enclosures. These well-constructed building envelopes allow for smaller, highly efficientair conditioning systems such as an Air Source Heat Pump. These air tight homes requiremechanical equipment such as Energy Recovery Ventilators (ERV) to address the health and safety of its occupants providing fresh air exchange while retaining latent heat in the air When powered by renewable energy such as solar, energy savings are enhanced through self reinforcing principles of minimized energy loads requiring smaller PV systems and quicker payback periods .
