Far hectare Eco-house and off-line Bashny.Net

One of the main factors impeding the implementation of solar, including passive solar technologies in individual housing construction in the Primorsky Territory, is the lack of experimental data, confirming the effectiveness of the passive solar heating system in the conditions of the region.

At the same time the need for their practical application is great - just remember to 13,000 plots allocated for development in Khanka district of Primorye in the framework of the program "Far hectare." After all, the bulk of areas not provided with engineering networks ...




Therefore, the purpose of carrying out this winter 2015-2016, the joint research workshop of the Department of resource-saving architecture AIG ISH FEFU and laboratories 07 IPMT FEB RAS, has been monitoring the performance of passive solar systems of individual residential homes in the south of Primorye. The main condition for the selection of the observed object - straw eco Solar-Sb - was the absence in the house other than the direct solar radiation, heat

The house this winter was uninhabited, and not heated. House cools loft, which insulation has not been fully completed. Also, due to work in progress on the interior decoration of heated volume of passive solar space system has been exceeded by more than a third. System Type - direct heating, thermal mass - light gray concrete floor in the atrium - winter garden house (on the completion of a dark matte granite)



Overall, during the period of observations from December 14 to March 14, indoor air temperature of the house (1st and 2nd floor) was kept near 0 ° C mark. Daytime air temperatures below 0 ° C were observed in the residential part of the house, the second floor, only 6 days. Maximum daytime temperatures inside the house on a sunny frosty weather were within + 2 7ºS. In this house, with all the imperfections, very well kept the sun's heat. For example, on February 8 overcast snowy morning in the house was about 0, at -19 on the street. The day before was a sunny day.

The maximum difference between outdoor and indoor air temperature during the coldest weather with minimal cloud cover reaches 12 - 20 ° C. At the same time outside air temperature at the construction site during the day and below -10 ° C was observed 26 days below -15 ° C at night - 34 days

. In general, given that the project passive solar system of direct heating is not planned as a primary heating system of a residential house Solar-Sb, the findings confirm its high potential for a possible contribution to the overall building heating system at the end of finishing work. In the summer overheating in the house as comfortable conditions persisted. More complete data is now being prepared for publication ...



Small residential ekomodul Solar-5S in construction. According to estimates, the share of passive solar heating in ekomodule was to be 57% for the cold season.
