Passivhaus Design Analysis

1254 Words6 Pages
Passivhaus is a particular type of building construction that provides optimum comfort both in summer and in winter. It also provides air tightness, good thermal performance and mechanical ventilation. It reduces the amount for heating demand. A Passivhaus design includes: - Excellent levels of insulation with very little amount of thermal bridges - Good levels of air tightness - A mechanical ventilation to allow a high quality of indoor air - Internal heat sources and passive solar gains The Code for Sustainable Homes, which was introduced in 2007, is a national standard for sustainable design and the construction of new domestic buildings. This Code accounts the whole home as a complete package, evaluating its sustainability against nine categories as follows: - Energy/Carbon Dioxide - Water - Materials - Surface water run-off - Waste - Pollution - Health and well-being - Management - Ecology A 1 to 6 star rating system is used (one which is the lowest, six the highest) to place a minimum level for water and energy. Therefore, it can be seen that both of these have different aims- The Passivhaus deals mostly with energy requirement for space heating whereas the Code sets out a wider scale of environmental standards.
