"Smart" yurt due to the project of ISTU students will appear on the shores of the lake Baikal

Multi-Comfort House in the form of a yurt, designed by students of the Institute of Architecture and Construction at ISTU and equipped with innovative designs of university scientists, can be installed in one of the tourist complex in Vydrino (Irkutsk region). According to the project manager, head of the subdepartment of Engineering services and life support systems at ISTU, Mikhail Tolstoy, currently there are negotiations with the leadership of the camp site.

To remind, the project of a residential district of young architects, every inch of space of which meets all the requirements of energy efficiency and comfort, was praised by the jury in March 2012 at the international student competition "Multi-Comfort House "Saint-Gobain" in Moscow. Participants were required to develop a sustainable management district for 12-15 families living with the presence of essential services to ensure an effective scheme of "work-life". The main condition of the contest is that all objects have to bear the status of energy-efficient and environmentally friendly ones. The location of the district was selected the pool grounds of the River Trent in Nottingham (UK).

"The main feature of the multicomfort house is its economy”, says Mikhail Tolstoy. “The heating costs are small in such home, because the heat loss through the building envelope is the lowest (it is annually spent up to 15 kW * h/m2 on heating). The use of ventilation systems with heat recovery saves on heating the incoming air. Alternative energy sources allow gaining the independence from fluctuations in energy prices. In addition, the advantage of multicomfort home is the lack of emissions into the environment. Originally the house was designed for the weather conditions of the UK, now the students are guided by a recreational area in Vydrino and offer to make the yurts of hotel-type for tourists. "

One of the authors, fifth-year student, Tat’yana Lenik, notices that the Siberian version of the house will be much different from the European counterpart. According to her, the structure of the walls was changed: a layer of insulation became bigger due to the harsh of climatic conditions. The roof, which had previously acted as a collection of precipitation over plum in the center of the tank, which is under the house, was also changed. It was impossible in the new environment, because accumulating snow will carry a heavy load on the roof. In this case, the designers plan to use rainwater, installing gutters on the edges of the roof.

"We abandoned the idea of a roof in the form of a crown. Vydrino is on the border with Buryatia, so it was decided to change the roof in accordance with the traditional Buryat architecture. The shape of the building in the form of a decagon is more effective because the exterior wall area is significantly less than the rectangular home. Accordingly, we will get less heat loss due to the building envelope”, says T. Lenik. “Despite the fact that this area is located near the lake Baikal, it has a poorly developed infrastructure. We want to make the coast attractive to locals and tourists. Russia has only recently started to build energy efficient homes, while in Europe it is no longer a novelty. This theme is very promising and interesting to explore. I believe that students should always pay attention to the latest technologies and trends. "

According to the authors, "smart" home will be equipped with a ventilation system with heat recovery, which allows to ensure clean air room with a comfortable temperature, thereby reducing the load on the heating system. "Fresh air is heated by the passing tair hrough the heat exchanger," says T. Lenik.
An important role in the project is a hybrid solar-wind installation, which consists of the wind turbine, generating energy, solar collectors and solar panels. M. Tolstoy emphasizes that the main feature of this facility is the use of own scientific development of Irkutsk Technical University. In particular, solar collectors of the university inventors have passed numerous tests and are proven to be effective. Unlike solar panels that directly produce electricity, solar panels heat the material (collant) for preparation of domestic hot water or, if required, central heating.

According to Mikhail Tolstoy, the soils tests spent in Vydrino have proved the possibility to use heat pumps, receiving energy through the flat collector laid in the ground to a depth of 2.5 m Such pumps are able to meet the demand for heat even in cold days.
A "smart home" is suitable for comfortable family living, consisting of 5-7 people. Thus excepting the low energy consumption, the house provides acoustic comfort, safety, and does not cost much to operate it.
