Everyone has dreams about a beautiful and warm house to which they return after a hard day’s work to rest and to find peace and quiet. They say – „where there’s a will, there’s a way”, so reach for your dreams, your vision of a perfect home full of warmth and comfort. You can find such warmth – literally and figuratively – in a passive or energy-efficient house. However, if you decide to choose that kind of house, you must rethink everything from the beginning. As everyone knows, there are always countless details to be taken into account, and this article focuses on just the most important ones which have the biggest effect on the final outcome.
Exposure to sunshine
The most important factor which you must consider while selecting a plot for a passive and energy-efficient house is the exposure of the land to sunshine. This is associated with the house location which will be determined later. The main principle of the passive and energy-efficient house is that it sources energy from sunbeams to use it later on to heat up the house. Therefore, the more sunshine reaches the plot, the more energy is supplied to the house and so its heating cost is minimised.
Location and shape
The most desirable site will be a flat plot or a plot slightly descending southwards. The plot slope makes it possible to reduce the area of the northern wall which the coldest one and to increase the area of the southern wall. It is most exposed to sunshine during the daytime in every season of the year. Also, beware of plots situated at the foot of mountains because the peaks are likely to cast a shadow which will block the entire solar energy.
The shape of the plot should approximately be rectangular or square because it will give you a lot of space to rotate the building so as to find its best possible position against the cardinal directions.
The passive and energy-efficient house is expected to minimise the energy consumption. Therefore, during the house construction, the technical aspects should have priority over the visual appearance. Simplicity and functionality are most important. The M3 System technology offers two lines of products: Classic and Modern. Our classic houses strictly comply with the requirements set for the energy-saving and passive building construction. They are characterised by a simple body shape with gable roofs and small amount of glazing. The Modern Line includes houses with a hip roof and large glazed areas. The larger area of the roof and windows exposes the building to greater thermal losses; however, buildings made with the M3 System technology guarantee that your bills will still be low.
You cannot disregard the aspect of your plot neighbourhood. The most important thing is to know whether anyone plans to build high buildings next to your house in the future which might shade the building and reduce its access to the solar energy. You can get such information from the Local Spatial Development Plan, available in the office of the borough where the plot is situated.
Objects on the plot
Imagine yourself standing on the plot and looking around. If there are trees on it, they better be fruit trees since you can cut them out without a problem if they are in your way. They are not desirable if they grow e.g. in the middle of the plot where the building is planned to be built. In the later stage of the plot development, the deciduous trees should be planted on the southern side where they will give shade and cool down in summer and in winter, when leaves fall down, they will not prevent access to sunbeams. On the northern side, coniferous trees should be planted. They remain green all year long and provide good protection against the cold northern wind which cools down the building.
Take a look now under the soil in your land. The soil type and the level of groundwater determines the foundation design and the costs of performing additional works, e.g. to dewater the plant. It is recommended to carry out geotechnical research tests to check the soil load-bearing capacity and the groundwater level. The best foundation soils are those composed of sand and gravel and showing good permeability, allowing water to flow down freely instead of being held in a single spot and forming „lakes” of standing water. Such phenomena may cause you a lot of trouble. In case of loamy, clayey and silty soils, it is necessary to provide foundations with a good anti-moisture insulation.
Avoid plots with high groundwater table level because you will have to carry out additional works to insulate the building. Avoid organic soils such as peats which feature very low load-bearing capacity, landslides and flood and post-mining areas since there is a risk that your project will incur high costs related to making a proper foundation for the building. Also in this case, the solution comes from the sensational M3 System technology which, thanks to a small weight of the building and to founding it on the foundation slab, allows you to build a house on the above mentioned soils without additional costs. Use the defects of the soils to negotiate and reach a very good price for the plot.
It will be an advantage of the plot if you find the electrical, network water and sewage system connection near it because you will not have to bear any additional costs to connect utilities to your building. A remote field provides a lot of sunshine but is not necessarily a good choice if you have to invest into several electrical posts or kilometres of water supply pipelines. It is very important that the plot also is connected to an access road.
You should also check the ownership right to the plot. If you know the Land and Mortgage Register number, you can do this on-line at: https://ksiegi-wieczyste-online.pl/
