An important aspect of jobs in HVAC is to enhance energy efficiency by monitoring what escapes from buildings and into the atmosphere. Meanwhile, all buildings need a generous supply of fresh air to protect the wellbeing of the occupants. It is fair to say that those with jobs in HVAC are walking on a fine line as they try to balance between air tightness and ventilation.

In order to enhance energy efficiency, those with jobs in HVAC pay attention to three issues – thermal insulation, air-leakage control, and ventilation. In the case of ventilation, mechanical ventilation with heat recovery appears to be the most proficient. Heat exchangers in such ventilation systems preheat the incoming fresh air, using heat recovered from outgoing stale air. This helps those with jobs in HVAC to achieve the dual goals of saving energy and improving the air quality within buildings.

In terms of air-leakage control, cutting-edge construction techniques such as structural insulated panel technology enable those with jobs in HVAC to improve air tightness of buildings. The technology consists of two sheets of strand panels with a rigid urethane insulation core, which have unique structural properties. The panels are connected with a special jointing system, with the intermediate floors supported by timber I beams.

Structural insulated panels guarantee a high degree of air tightness. Combining this technology with mechanical ventilation with heat recovery, jobs in HVAC are made easy and efficient in terms of delivering significant reductions in energy consumption.
