Family House

Szendehely, Hungary
Completion: Under construction, Architect: Balázs Tőkés, Engineer: István Mucsina, Developer: László Rusznák
With the construction of the invention hereby I would like to demonstrate how it is possible to build a house with 0 CO2 emission from a maximum amount of 100.000 EURO.

Energy: 

We construct a passive house completed with solar cells (photovolatics, PV for short) so we ensure the annual surplus energy.

Indoor Climate: 

The building has a southern-facing aspect with a lot of window surfaces to ensure the environmental atmosphere and the solar yield in winter. The properly constructed building structures ensure the shading during the summer. The ventilation system, completed with ground colletor provides the fresh air.

Environment: 

As the building will be my home, during planning period we have been taking my family's needs into consideration. We also ignored all aspects, which are essential when building a passive- house.

Most of the people are aware of the importance of environmental protection and that building energy-saving houses (in large numbers) has a primarily importance with respect to our planet. Unfortunately, building such houses nowadays means significant financial investment surplus costs in the hope of subsequently energy (financial) savings. This extra cost is the only obstacle of spreading passive and active houses in large numbers.

 

Hereby I would like to give thanks to the following companies for supporting my project:

Saint-Gobain Construction Products HungaryKft.

BASF Poliuretán Hungária Kft

Hegler Plastik GmbH

 

Kind regards,

Rusznák László

Active house building technology:
Using the technology buildings’ construction is possible with almost 0 energy consumption with more favourable budget in comparison with present technologies. The house, being under construction, is announced on webside: http://www.activehouse.info/cases/family-house and can be viewed on the spot.
Data of the construction: Blowerdoor test: 0,06/hour
Energy consumption: 4 KW/m²/year.
By enlarging the building the energy consumption/m² keeps decreasing.
The building - equipped with solar panels – produces more energy than it uses.
The present wall’s thermal conductivity factor is 0,079w/m²/K at wall thickness 30 cm.
The weight of the wall is 50 kg/m² and the wall is flexible, thus it can be well used in areas exposed to earthquake an in Arab countries.
The production speed of the wall can achieve 180 m²/hour. In this case cavities for windows, doors and installation have already been constructed.
Changes, of course, can be executed afterwards.
Construction time on the spot:
Substructure: 1 day/6 persons.
Bearing walls + roof + ceiling: 2 days/6 persons.
The price is maximum 1.000 EUR/m².
