We call our house DRESSED HOUSE.
People dress their bodies with clotting. Why we could dress our hoses with textile waste?
Our aim is to use waste from human activity - textiles,car tires, wood and plastic waste. These materials we used in building walls, roof and floors in our house to make better isolation.
We chose the direction south to the street and orient the house with its widest part to this direction. The building has two levels. The entrance is located half to two basic level on the south facade. On the upper level are the living room, the dining room, the kitchen and a toilet. On the lower level have two bedrooms, bathroom and wardrobe to each of them and one technical room, where it is located the heating and air conditioning system. One of the bedrooms have enough space to allow part of it be used for work area.
The lower level of the house is under the ground and only the south facade has natural lighting. The upper level of the house is fully glazed south facade. The glazing is divided into two parts - internal and external. The space between two windows is a garden. The front part of windows are movable and in summer can be opened to provide natural conditions for plants. Winter, when the external windows are closed, the space will be used as a winter garden.
The angle used for the roof is 25 degrees, which is suitable to place photovoltaics. They will meet the needs of the house for electricity.
The main construction is timber beams and columns. The external walls of the house are made of (from exterior to interior): panels from plastic waste, isolation from textile waste, gab for exhaust air circulation and wooden panels. The same detail we use for roof. The internal walls are flexible and it’s take possibility to adapt house for individual needs of occupants.
For terrain countraforts at the lower level we used car tires and the spaces between them are filled with construction waste. In the space left in the facades, roof and foundation circulating exhaust air from the heating and ventilation system.
For air heating and cooling we use pressure-exhaust ventilation system with heat recovery unit.
This system consists of the following components:
• Sampling of fresh air through pipes up to 2 m above ground, outside the building in the yard;
• Purifying filter mounted on the vertical part of the duct;
• Ground collector pipes;
• Galvanized steel pipes inside the building;
• Discharge and suction grilles;
• Heat recovery unit with 77% efficiency;
• Electric heater for the feed pipe;
• Fixed grill discharge of exhaust air to the façade.
The required amount of air is based cover the heat loss in residential areas. In all rooms is obtained from 0.8 to 1.0-fold air exchange.
Fresh air is taken from the yard. Earth passes through the collector, which in winter is heated by an external computing winter temperature -10 C to  -0,4 C and the summer is cooled by an external computing summer temperature +31 C to + 17,6 C .
After the earthly air collector shall enter into a heat recovery unit with 77% efficiency, the heat and the cold exhaust air is fed into the upper zone in residential areas.
This pressure-suction system meets the requirements of a passive building:
• Meet the needs of passive house fresh air;
• Covers winter heat losses and is not needed other heating system;
• During the summer season brought air temperature, which does not require additional cooling of the air conditioning machine;
• It has high-efficiency use of the parameters of the exhaust air heat exchanger in the air - air.
The exhaust air from house cooling or heating will take to facades and floors (in gaps between construction layers) for second use and will increase the efficiency of the process.
To cover the needs for thermal energy to heat water for hot water in summer is to vacuum-tube solar installation on the roof.
There is a playground in the plot below which will be located tank for collecting rainwater. Through a system of filters that rainwater will be used for domestic purposes.
The capacity of installations in house can calculate according to individual needs.
The yard has rich vegetation that is planned to keep the house from overheating in summer. Plants in inner garden will provide fresh air in the winter and create comfort.
Systems produce electricity from solar energy, use of rainwater for domestic needs and heating and ventilation system, which uses the heat of the earth, makes the house a self-sufficient system. Using recycled materials, which can be local, will minimize its ecological footprint.
We would like to create and take care of our house and therefore able to isolate well dressed to be able to consume minimal power. Most of all passive house will minimased it’s ecological footprint when the occupants live more sustainable way of life. It is mean to save energy, reduce water consumption, compost the waste, use recycled furniture, etc.
