The building sector accounts for significant portion of total final energy use in most countries. One way to reduce significantly building energy consumption is to adopt energy efficiency technologies and strategies. Due to environmental concerns and high cost of energy in recent years there has been a renewed interest in building energy efficiency. Passive House (PH) standard provides a cost-efficient way of minimizing energy demand of buildings in accordance with global principle of sustainability. However, it is ongoing challenge to improve building energy efficiency without compromising indoor environmental quality. The objective of this paper is to review the interactions between energy performance and indoor environment quality in buildings with PH standard, considering parametric sensitivity study including effects of diverse parameters on PH building performance. Passive House technologies including heat and cooling recovery ventilation, pre heating/cooling fresh air, pre-ventilation and passive cooling are presented considering different weather conditions. Thermal comfort represented by recommended thermal range and comfort zone and indoor air quality indicated by CO2 concentration have been numerically and experimentally analysed. The simulation and measurement results illuminate that it is possible to realize energy efficiency and favourable indoor environment in PH buildings at the same time.

Owing to global energy crisis, various technical strategies are adopted for energy conservation in buildings through energy-efficient technologies. One of the significant ways for this purpose is by installation or usage of heat or energy recovery device which is known as one of main energy-efficient systems that will decrease the power demands of building heating, cooling, air conditioning and ventilation loads. In order to have an insight into existing knowledge leading to understanding of previous works and researches carried out concerning the area, this paper presents and discusses physical and performance parameters of heat recovery unit and the significances of these parameters on operation and efficiency of the system. In addition, areas that have not received much research attention and that warrant future analysis of this technology are also highlighted.
