The 10 most important things that we should know while building a house - part III

4. Utilities

The value of the plot, as well as the budget for a dream home, is significantly influenced by the availability of utilities. Therefore, before purchasing, it is worth to get a base map for design purposes (Master map) in the Department of Cartography and Surveying of the City or District Office. On this map we can find the distance between the plot and municipal networks. The closer they are, the lower the cost of connecting the plot will be. It is also a necessary attachment to the application on land development conditions.


5. Budget

Although it seems obvious, let us remember that while planning a budget, we should include not only building a house (as a shell unit), but also finishing, an interior design and land development, i.e. hard-surfaced road, plantings and planned utility connections or external installations. The building will generate fixed fees for utility consumption and minor renovation works such as painting.

Approximate distribution of costs:

Staging (although more often used in the case of large investments, e.g. 2-3 stage building of a housing development) is also possible in the case of single-family house. We can plan the subsequent construction of a separate functional zone or postpone finishing the attic, or even the whole storey of our house. However, we must take into account the difficulties- results of this situation, for example the construction crew interfering in our family life, the need to dismantle some of the existing elements, such as a part of the roof slope or walls for new entrances connecting parts of the building from different stages.


7. Economy

The current standards are more and more restrictive in terms of energy and they oblige us to use materials that provide more warmth (having higher thermal insulating power). It is worth investing in them, because the costs of energy-saving technologies will pay off in the form of smaller service charges, e.g. for heating. The building and operating costs will also be reduced by the compact, simple body of the building and optimal glazing size.

An exemplary amount of pellets (one of the fuel type) necessary per year to heat a house with an area of 200 m2, assuming boiler efficiency of 85%:

When planning a home, it is good to take into account the actual needs of the family. You should design a house that is „tailor-made”, not an „exaggerated” or for a multi-generational family. We should avoid the least economical solutions such as basement (due to the cost of building it) and unnecessary cubature, such as an attic, which is not used but has to be heated.


8. Ecology

While planning a house, some eco-friendly solutions should be taken into consideration - solar collectors or heat pumps. These solutions are becoming more and more affordable, and additionally some endowments for them are also possible. Proper location of the rooms having the cardinal points in mind and the location of the largest glazed areas from the south will allow you to acquire free energy, and thus the house will become more ecological.

Electric energy usage
The estimated consumption of electricity in a traditional building is 25449 kWh/year. The usage of a heat pump enabled the reduction of electricity costs related to heating by about 78%. The total energy yield from the photovoltaic system was 4787 kWh/year. Savings from a properly selected ventilation air recovery system, after taking into account the consumption of electrical energy by the recovery system equals 1586 kWh/year. The biggest savings resulting from lighting control system were obtained for outdoor lighting, which in the building with traditional installation was turned on for 5 hours a day, and thanks to the usage of motion detectors, the estimated time of the lighting was lowered, to about 1 hour a day. In order to calculate the final estimation with the electricity supplier, the total electricity demand of the building should be reduced by the amount obtained from photovoltaic panels. According to this, for a building equipped with an intelligent electrical installation, a heat pump, photovoltaic panels and a ventilation air recovery system, the estimated energy consumption will be 3136 kWh/year.
