PASSIVE HOUSE KEY FEATURES

• INSULATION - very low U-values and almost no thermal bridging
• AIR-TIGHTNESS - very high level of air-tightness
• PASSIVE GAINS - high utilization of solar & internal gains
• MHRV - excellent air quality through efficient MHRV system

The passive house represents the most consistent concept of sustainable building today. During the construction stage the passive house concept requires quality workmanship derived from a good understanding of the passive principles by all participants. At MBC Timber Frame we pride ourselves in our attention to detail in order to achieve these standards and minimize any impact on the environment. All projects are evaluated by our team of experts to determine the most cost effective solution, and we apply the principles of value engineering to bring real savings to you the client. Our experience is your guarantee, as MBC has the knowledge and know how derived from a successful management team that have been involved in all aspects of timber frame construction for over 20 years.

The term Passive House is generally considered to be a house in which heat-losses are reduced to such a high standard that minimal heating is necessary. The key features of a passive house are high levels of insulation, air-tightness, and elimination of all cold-bridging combined with a heat-recovery ventilation system. The U-values of the exterior building components generally range between 0.1 and 0.15 W/m2K. This standard has been named "Passive House" because the passive heat inputs – delivered externally by solar irradiation through the windows and provided internally by the heat emissions of appliances and occupants – essentially suffice to keep the building at comfortable indoor temperatures throughout the heating period. It is a part of the passive house philosophy that efficient technologies are also used to minimize the other sources of energy consumption in the building, notably including electricity for household appliances. A passive house is a building in which a comfortable interior climate can be maintained with minimal active heating and cooling systems.
