![](../images/clearsp.gif) | After having constructed the first in CIS straw bales building, BD IAE decided to develop the design of fully autonomic available for a middle class ecohouses with natural materials and to construct the demo EcoHouse in Minsk in 1998.
![](../images/clearsp.gif) The design has been developed with participance of Minskgrazhdanproekt and includes:
wooden
2-level frame filled with straw bales, hothouse -- winter garden,
artificial lake for conserving rain water and increasing solar insolation during
spring -- autumn time,
South looking roof -- heat collector and ground heat accumulator under
the house,
forced ventilation system with heat recuperation and channel in the ground, as well as closed permacultural household-domestic sewage and wastes utilisation system at the adjoining the house plot for increasing its crop capacity.
![](../images/clearsp.gif) The cost of 1 m2 of living space is about $150, that is 3-4 times lower than of traditional dwelling, and energy costs for heating are close to zero (the existing dwelling even the new one has a consumption of 200-400 KWh/m2 per year). Equipping the EcoHouse with photo-electric panels makes it fully independent upon outside communications. | ![](../images/clearsp.gif) | ![](../images/clearsp.gif) |
