It is intended primarily for new buildings, although it can be applied to refurbishment projects, but this can be expensive.

−	Passivhaus suggest that, 'A Passivhaus is a building, for which thermal comfort can be achieved solely by post-heating or post-cooling of the fresh air mass, which is required to achieve sufficient indoor air quality conditions – without the need for additional recirculation of air.’ This means that a traditional heating or cooling system is no longer essential.	+	Passivhaus suggest that, 'A Passivhaus is a building, for which thermal comfort can be achieved solely by post-heating or post-cooling of the fresh air mass, which is required to achieve sufficient indoor air quality conditions - without the need for additional recirculation of air.'

	The Passivhaus standard can be achieved by measures including:		The Passivhaus standard can be achieved by measures including:

−	Whilst Passivhaus adopts the principles of passive design, it differs in its imposition of an overall limit on primary energy consumption. This limit includes; domestic hot water, lighting, projected appliance consumption, space heating, fans and pumps.	+	Whilst Passivhaus adopts the principles of passive design, it differs in its imposition of an overall limit on primary energy consumption. This limit includes domestic hot water, lighting, projected appliance consumption, space heating, fans and pumps.

	The primary energy demand target must be met in all cases, and either the specific heating demand target or the specific heating load target must be also met. In addition, there are limiting values for the performance of the building fabric, doors and glazing, ventilation systems, air tightness levels and thermal bridging. See Passivhaus [http://www.passivhaus.org.uk/standard.jsp?id=18 Outline specification] for details.
