Housing and communal services prices are biting harder and more persistently,the ecology in the city is not improving either. What to do? Build an energy-efficient house! This is exactly the kind of project we will talk about today. This unique project was prepared for a competition by the famous manufacturer of insulation Rockwool. The house combines modern forms and traditional materials (ordinary clay bricks), the latest achievements of science and technology (solar collectors and photovoltaic panels) and an almost complete absence of complex automation (the so-called smart house), comfortable warmth in winter and soft coolness in summer. This project is an environmental standard of the future - a house with 100% solar heating. These almost fantastic possibilities will be realized thanks to a huge solar accumulator - literally and figuratively the "heart of the house", receiving energy from solar collectors; impeccable polyurethane foam insulation (made by spraying); as well as ultra-energy-saving glazing. The absence of complex automation, various electronic systems and other elements inherent in a smart home can be called the main advantage of this completely easy to maintain (the most complex element here is the four-way valve), very comfortable and extremely reliable solar house. Olga Makarova, architect, interior designer Likes to work with projects in which elements of eco-style can be used. With pleasure she uses simple, natural, environmentally friendly materials. Olga sees her main goal as an architect in creating a harmonious living environment for her clients. ecodesign-online.ru
Architecture
The shape of the building allows the sun to reach as much as possibleto enter the interior. The windows are positioned so that the sun's rays literally penetrate the house. The rounded shapes of the building help to reduce the area of the facade and, as a result, reduce heat loss. Minimization of the northern glazing and huge southern stained-glass windows are fully consistent with the concept of a solar house. At the same time, in the energy system of the house, the influx of heat through the southern glazing in winter is not fundamental. Therefore, the glazing is made with a negative angle. This guarantees coolness in the summer and comfortable lighting all year round. Panoramic, huge windows allow you to "let" the surrounding landscape into the house. Thus creating the most comfortable of all possible options for merging man with nature.
Wall material and foundation
Structurally, the house is built in a traditional manner:in clay brick and concrete. This increases thermal inertia and reduces peak loads on the heating system, and also provides a comfortable microclimate in the house. The foundation was a heat-insulated reinforced concrete slab on a sand cushion. The use of such materials allows construction on almost any soil.
Ventilation with heating
The ventilation system complies with German standardsstandards, but takes into account more severe climatic conditions - the system includes an additional unit that uses geothermal heat, thus compensating for harsher conditions in winter and fully providing the necessary cooling in summer.
Heating and air conditioning system
The heating system is designed in the form of "warm"floors" and "warm walls", which allows to significantly reduce the required temperature of the coolant to 23-25 degrees and to make maximum use of the energy collected in the accumulator. This system also allows to provide passive cooling with the help of an additional unit.
Solar storage
Solar accumulator, the same as we alreadyThey said that the heart of the entire energy system of the house is a powerful (25 m3) heat accumulator. It accumulates energy generated in the summer by a flat solar installation. The heat loading and unloading system is three-level, which allows for a more complete loading of the heat accumulator with energy and its most economical use. Inside the accumulator (which is a huge insulated metal cylinder) there is also a three-level hot water accumulator, which provides the house with a large supply of it and economical energy consumption for heating.
Fireplace stove
Architectural and engineering design of the houseallows you to harmoniously fit in a fireplace with a water circuit (Edil Kamin), which will become a center of relaxation for those who like to sit by the fire on festive evenings with a cup of coffee or a glass of cognac. A powerful solar accumulator is ready to accept any amount of energy, at any time convenient for the owner, without losing a drop of heat.
