Recirculation ventilation increases energy efficiency and solves the problem of energy savings in the case when 70%-80% of the exhaust air enters the ventilation system again.

These systems operate by capturing waste heat from outgoing air and transferring it to the incoming supply, thereby mitigating energy losses associated with ventilation.

Energy-recovery ventilators, also known as air heat exchangers, are mechanical ventilation systems that remove stale, polluted air from homes and replace it with fresh outdoor air.

In all, seven separate VRF systems were installed along with three air handling ventilation systems with heat recovery capability. This configuration of separate systems accommodated the phased ...

As the mercury rises, there is nothing better than retreating into a cool, air-conditioned room -- but between toxic coolant gases and energy use, what does a cooling system cost the environment ...

The ERV, Energy Recovery Ventilation system, does things a little differently. It captures both heat and moisture, your indoor humidity.

The “Ask a Builder” series is dedicated to answering some of the many questions Fairbanks residents have about building, energy and the many other parts of home life.

This did waste energy, but made the indoor air fresher. The most energy-efficient method to solve your indoor air-quality problems is to install a fresh-air heat recovery ventilator system.

Heat recovery ventilation (HRV) simply moves heat between incoming and outgoing air. In the winter, the exhaust air is heated, so the heat exchanger uses that energy to warm the incoming air.

Heat recovery and ventilation systems are integral to contemporary approaches in reducing building energy consumption and enhancing indoor air quality. These systems operate by capturing waste ...
