Wooden premanufactured houses – construction and energy performance
More and more house builders decide in favour of a wooden premanufactured house. There are various reasons supporting such a decision, since modern premanufactured houses have several advantages compared with conventionally built houses. Their industrial prefabrication makes it easier to plan and carry out the building project: It can support consistent quality, contribute to a structured construction process and facilitate cost planning. Your dream house can be planned individually thanks to modern computer and construction technologies.
The construction method and the building material wood allow the construction and the building services to be coordinated with the applicable requirements for thermal insulation and building physics. The actual energy performance of a house depends on its construction, the components and systems used, the quality of execution, its location and the occupants’ individual behaviour. Due to long-term changes in oil and gas prices, the operating costs of houses are an important consideration. Under these circumstances, a well-planned thermal-insulation concept can be one aspect of the long-term planning of a building.
Wooden premanufactured houses and thermal insulation
The thermal-insulation properties of a wooden premanufactured house depend on its specific construction, the materials used and the quality of execution. Relevant factors include the construction design, the building execution and the physical properties of the materials used. Wooden houses have been built for a long time in Scandinavia and in many mountainous regions.
House and heating carefully coordinated
Within each heating system, it is important to coordinate all its components carefully. For example, the pipe system should be installed in a way that keeps pressure losses as low as required for the system. Building a premanufactured house can involve coordinating the house construction and the building services with one another. The choice of the appropriate energy source depends on the individual building, the applicable requirements, the location, the technical systems and the occupants’ behaviour.
In each case, the applicable requirements for primary energy demand must be observed. When assessing the overall building concept, technical, ecological and economic considerations, as well as the occupants’ individual behaviour, may play a role.
Suitable for different energy sources
Oil and gas are still used for heating. Modern boilers can achieve high efficiency levels, depending on the system, its design and its operation. House builders may also consider energy systems that use renewable energy sources, such as solar thermal systems or geothermal systems. Their suitability depends on the location, the building concept, the technical requirements and the individual energy demand.
Biomass systems, including wood-fired heating systems, are another possible option. Their environmental performance depends on the origin of the fuel, the efficiency of the system, the emissions during operation and the energy required for production and transport. A reliable assessment therefore requires consideration of the specific system and its overall balance.
