Issues such as sustainability, healthy living and naturalness are increasingly conquering the world of house building. Architects and builders are placing increasing value on a construction method in which ecology and economy are brought into harmony with one another. Best example? The organic house!
But what actually distinguishes an organic house from other ecologically built houses such as the passive house or the energy-efficient house? What are the advantages for the builder and what additional costs should he expect? Does the investment in an organic house pay off financially and energetically??
Building an organic house – The basic idea: Ecology and economy in harmony
Sustainability is in the construction industry has been a topic for a long time. The original idea behind the development of organic houses is that ecological and economic aspects should be combined under one roof. The typical organic house therefore consists of natural and renewable raw materials such as wood or clay, which at the same time reduce energy consumption in the house and ensure a healthy indoor climate.
Building ecologically – in the case of the Biohaus, means that predominantly sustainable and pollutant-free resources are used both for the construction of the building envelope and for the interior design. Special attention is often paid to the CO2 balance as well as the energetic and moisture-regulating properties of the materials used. The latter is important to create a healthy indoor climate in which allergy sufferers feel comfortable and mold has no chance.
Building economically – this is the second main focus of the Biohaus. Similar to the passive or plus energy house, the goal is to build as efficiently as possible, so that only little energy is used and thus additional resources are conserved. For house residents, lower energy consumption also means that the monthly household budget is also relieved in the long term.
Build an organic house – Only natural and low-pollutant materials
The Biohaus stands for resource-saving and healthy construction. For this reason, ideally it should consist exclusively of low-pollutant, renewable and natural materials, from the shell to the building envelope to the wall cladding and the interior fittings.
Typical materials that are used at the Biohaus are:
– Wood and clay for the facade
– Insulation materials such as flax, hemp, cellulose or straw
– Cork, wood or sustainable carpets for the floor
– Low-pollutant wallpapers and paints for interior design
Wood as a building material usually forms the basis for building an organic house, as it combines many ecologically valuable properties. Wood is a renewable raw material that binds more CO2 as it grows than is later released during processing into a building material. It is completely biodegradable and, thanks to its moisture-regulating properties, ensures a pleasant room climate.
Nevertheless, an organic house does not have to be a purely wooden house. Earth building materials and earth plaster systems have similarly excellent properties and are often used in organic house construction.
Organic houses offer these advantages
Not only builders are increasingly interested in ecological construction, but also more and more property developers who like you on building portals HouseXXL find clearly listed, offer the construction of organic houses. On the one hand, this is due to the fact that the idea of an all-round healthy and sustainable life is manifesting itself in more and more areas, from nutrition to one’s own way of life to the living environment. On the other hand, the organic house offers advantages that cannot be dismissed out of hand.
Thanks to their construction and the good material properties, organic houses usually have a lower energy consumption than conventionally planned single-family houses. A lower consumption of energy also means that the ancillary costs for the residents are sustainably reduced. For maximum cost savings, however, the bio house should be planned as a passive or efficiency house.
One aspect that is still neglected when building a house is the living environment. In particular, those who are allergic to house dust, mold or other substances should make sure that healthy living is possible when choosing their house. In the Biohaus, the natural building materials regulate the humidity in such a way that the formation of mold or dust is hardly possible. In addition, only low-emission building materials are used.
Ultimately, the main argument in favor of an organic house is that it is built in a way that conserves resources and does not harm the environment. The building materials used usually grow back, can be recycled and come almost entirely from nature. In addition, it is extremely robust. Wood, for example, is considered to be an extremely resistant and durable building material.
A positive energy balance – save energy with the bio house
In an organic house, in addition to the sustainable choice of materials, particular attention is paid to keeping the subsequent energy consumption as low as possible. As a result, the subsequent costs are permanently reduced, which means that the investment in an organic house pays off not only ecologically, but also economically.
Organic houses can be easily converted into a passive house with simple means such as choosing the right thermal insulation and radiant heat heating integrated into the walls. For this, a few basic requirements should be taken into account when planning. Large windows and the south-facing orientation of the house, for example, ensure optimal use of the sun’s heat.
Other types of house such as the energy-plus house or an energy-efficient house can also be combined with the construction of the bio-house in order to achieve the most positive energy balance possible. In this way you are helping the environment in two ways. On the one hand, resources are already conserved when building a house. On the other hand, low energy consumption continues to protect the environment.
Building an organic house – what are the investment costs?
How high the additional costs for the construction of an organic house are compared to other house types cannot be answered across the board, as the prices always depend on the desired standard of equipment. A simple wood and clay house with can certainly be realized with a small budget, while some natural materials such as cork floors or insulation made of cellulose flakes can cause high costs.
It is therefore important to have your own finances in view when planning – be it in cooperation with an architect or a property developer. So you can plan an organic house tailored to your budget. It is also worth comparing the offers of different construction companies with each other in order to really filter out the cheapest.
If you design your organic house directly as an efficiency house, you also have the opportunity to take advantage of various subsidies from the Förderbank und Kreditanstalt für Wiederaufbau (KfW) or the Federal Office of Economics and Export Control (BAFA). Many municipalities also promote sustainable building at community level. Simply ask the responsible building authority about funding opportunities and information materials.
In the meantime, the organic dream houses are not only available from a few specialized solid construction providers, but more and more prefabricated house builders are jumping on the eco wave. Using finished modules and freely selectable kits, you can design a complete organic house, which often brings savings compared to houses planned from scratch.
