A passive house today fits tomorrow's requirements for energy efficiency

The longtime partner of "Di Trade" - "IZOCAM" once again proved that not only it is the undisputed leader in the production of insulating materials of rock and glass wool, but a completely new look at building construction, namely passive houses. The name "passive" is due to the fact that the building is no need for active heating and cooling systems. These buildings do not differ in any of the other and each already built house can be transformed into passive.

 

On the seminar organized by company the "Di - Trade" in Sofia, Dr. Kemal Gani Bayraktar - technical marketing manager "IZOCAM" familiarize attendees partners and friends of the company that it is possible to build or renovate a building with a high degree of living comfort at extremely low power consumption. Through its program: Saint-Gobain Multi- Comfort (http://www.izocam.com.tr/p191-multi-comfort-houses.html) Izocam aims to minimize environmental impact, and focuses on komforta and welfare of residents (thermal and acoustic comfort, quality of indoor air, safety ...). Presented were executed projects of this type houses - both renovated buildings and newly built residential and public buildings. The concept of multi - comfortable house allows greater flexibility in designing the interior and exterior, reduces heat consumption, reduced and emisiite of CO2.

The construction of passive houses in Bulgaria is gaining momentum. Perceived energy crisis is an incentive for more users to realize for the operating costs of buildings and the need for radical measures to energy efficiency.

The building of a passive house is more expensive than standard construction, but in the long term with a similar building is paid initial investment because it saves energy for its heating and cooling.

It is believed that a passive house consumes 4 times less energy than a conventional house.

To be a home or building passive in their construction observe many rules and requirements for izolaziya. In practice, all building elements are isolated, and the links between them. The windows are necessarily three-compartment and the middle glass is with low emission. The walls, floors and the ceilings are isolated. Most commonly, after installation of the insulation, the wall thickness reaches and exceeds 30 cm in order to fulfill the standard of heat transfer - less than 0,15 W/m2. The doors are also well insulated and sealed on all sides.

In passive houses the annual cost of heating, cooling and ventilation systems should not exceed the total value of 15 kWh / m2 living (habitable) area.

On the other hand, the amount of energy consumption for heating, hot water and electrical work must not exceed 120 kWh / m2 per year.
