Abstract

Nowadays the demand for energy-efficient houses is increasing in order to reduce heating and cooling demand, to save energy used in houses. A mechanical induced ventilation system, also known as heat recovery ventilator (HRV) is required in all houses constructed after the year 2000. An HRV unit can contribute to increase energy efficiency and to reduce greenhouse gases emission by recovering heat from the inside of the house and delivering preheated fresh air to the house. Such a mechanical ventilator also leads to losses. This paper presents an energy consumption and logged heat loss data of a heat recovery ventilator unit in Newfoundland. MATLAB and Microsoft Excel are used to do all calculations and detailed analysis. The logged data shows that the cost of running an HRV in Newfoundland for a year in a house could be as high as $484 per year with an unknown air quality improvement.
