Building a traditional home is in itself a multi-stage and complicated event. It requires many investor skills, including planning and investing. How do you decide on a house design? It is worth using the help of engineers and architects specializing in low-energy, passive and RES building.
Who we are?
The design studio for Clean Energy Houses was created for investors who plan to build a low energy facility, ie one whose energy demand index does not exceed 40 kWh / m2. To achieve this, it is necessary to apply optimal design solutions under many criteria. Achieving this effect requires the cooperation of the design team, which in our case is made up of architects from leading design studios, designers, research and development staff from universities, practitioners and plant implementers, energy specialists, experts on small systems generating energy based on RES, as well as representatives of construction companies with great practice on very demanding facilities.
The task team, which participated in over a dozen foreign study visits (Austria, Germany, Great Britain, Denmark), develops new market solutions - innovative projects of energy-saving buildings with integrated energy systems, using the latest solutions in the field of energy-efficient construction and the use of RES.
How do we design?
When working on a low-energy house project, several factors have to be taken into account. It is important that it is adapted to the conditions of the plot, that is, it would use its potential. So factors such as the climate prevailing in a given region, the terrain on which the plot is located, its insolation and shading, the directions of the most intensely blowing winds are important.
Another important issue is the inclusion of the world's sides conditioning the correct positioning of the low-energy building on the plot - on the southern side, glazings with a larger area are planned than in the rest of the building to easily extract heat from solar energy.
From the location of the building plot, the location of the entry, neighboring buildings and vegetation - especially tall trees - the functional program of the house (ie the type, size and layout of the rooms) is strictly dependent. It belongs to the basic criteria for the selection of each project (regardless of the energy standard), but in the case of a low-energy building it plays a special role, because it must also be adapted to the conditions of the land on which the building plot lies.
Buildings designed as low energy are characterized by simple architecture and a compact body, construction materials from which they are to be made, are distinguished by high quality, and insulation materials with a low thermal conduction coefficient.
The risk of thermal bridges is reduced due to the appropriate design and construction of partitions of building partitions. In addition, in order to prevent cold air from entering and thus avoid additional heat losses, low-energy buildings have increased air-tightness of all external partitions (roof, walls, floors, windows and external doors), especially in installation punctures.
Buildings of this type are ventilated using mechanical ventilation with heat recovery, which ensures high air quality due to constant and efficient replacement in all rooms, while minimizing energy losses.
In the case of low-energy buildings, it is also important to integrate many solutions used in buildings, high-efficiency heating devices, such as condensing boilers, or devices that draw energy needed for space heating or domestic hot water production from renewable energy sources (heat pumps, for example , solar panels). Their mutual adaptation also allows easy control and management.
