  • Relaxation of noise protection regulations in residential construction

    Relaxation of noise protection regulations in residential construction

    After lengthy discussions, the National Council and the Council of States have reached a compromise on noise protection regulations. In new flats, at least half of the noise-sensitive rooms – i.e. rooms in which people regularly spend time – must now have windows that comply with the noise limits.

    If controlled ventilation is available, it is sufficient if the limit values are complied with in one room per flat or if a cooling system is installed. Alternatively, a building permit can also be granted if a quiet outdoor space and a quiet window are available.

    Remediation of contaminated children’s playgrounds
    In addition to noise protection, the remediation of children’s playgrounds contaminated by fertilisers and air pollution was also discussed. Public playgrounds must be analysed and remediated in future. The federal government supports these measures through the so-called Vasa Fund and covers 60 per cent of the renovation costs.

    In the case of private playgrounds and home gardens, remediation remains voluntary. Here, the Vasa Fund covers 40 per cent of the costs if the owners decide in favour of remediation.

    With the revision of the Environmental Protection Act, Parliament has made important decisions concerning both noise protection in new residential areas and the renovation of contaminated playgrounds. These compromises promote a healthy living environment and at the same time contribute to the sustainable development of residential and play areas.

  • Building technology planner S2B starts in Baden in January

    Building technology planner S2B starts in Baden in January

    From the beginning of the year, the company for building planning from heating and ventilation to plumbing and electronics, S2B Plan AG , will start advising customers. This means that the city of Baden will be the first planning company to combine all building technology trades under one roof, according to the start-up's media release. This is a novelty for the city. Because so far there has been no planning office in Baden for the full range of building technology. This niche is now being filled. For building projects, S2B Plan AG draws up all plans for heating, ventilation, plumbing and electronics from a single source. An analysis of the building technology is also offered for existing buildings.

    The company was only founded on December 1st by the Baden residents Christoph Barth, Daniel Burger and Thomas Schmutz. According to the announcement, the planned start in September had to be postponed. The corona pandemic thwarted the bill. Because suddenly the economic and social situation changed. Nothing has changed in the founding project, it says there.

    The team will now be available for customer advice from January. With the move into the offices at Badstrasse 34 in Baden on December 1st, the S2B Plan AG website and the entry on LinkedIn were activated.
