Acoustic assessment of PV systems on motorways

Acoustic assessment of PV systems on motorways

In the Energy Strategy 2050, solar energy plays a primary role in Switzerland's future energy supply. In addition to locations such as building facades and roofs, the potential of photovoltaic (PV) arrays along transport infrastructure (retaining walls, noise barriers, etc.) has also come into focus. The installation of solar panels there can influence sound propagation and can either reduce noise (as an obstacle) or increase it (as a reflective surface). As part of a pilot project on behalf of the Federal Roads Office (FEDRO), G+P accompanied the acoustic assessment of a planned PV system along a section of motorway, focusing in particular on reflections, which can lead to undesirable increases in noise for local residents.

Grolimund + Partner creates added value in all areas of its offering.

We are leaders in our specialist areas of outdoor noise, road surface acoustics, building physics, software and research & development. We provide high-quality services and develop solutions that benefit people and the environment.

One year of communicating values

One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

40 years of G+P: Celebrating creativity

To mark our 40th anniversary, we launched a creative challenge for our customers - the folding puzzle! It was about more than just skill: originality and creative staging took centre stage. The entries overwhelmed us and we are proud to honour the three most original contributions. But for us, every participant is a winner!

Our 40th anniversary

A weekend full of memories in Châteaux-d'Oex. Last weekend, we celebrated a special event: 40 years of company history. Our anniversary trip to Châteaux-d'Oex was a complete success, bringing us together with 60 employees from various branches. Thanks to bright sunshine, a great atmosphere and a varied programme, this weekend will remain unforgettable.

«What I appreciate most about G+P is the wide range of building physics topics that we are able to deal with on a daily basis as part of an outstanding team. It is a personal concern of mine to support and accompany our customers every day on their way to greater energy efficiency and sustainability. In this way, I can make a personal contribution to a ‘greener’ world of tomorrow, both for the general public and for my two small children, for whom I have plenty of time thanks to my ‘daddy day’ and 80% workload.»

«The highly specialized expertise within G+P enabled me to train in-house as an acoustician. Today, I am happy to pass on this knowledge to new employees. I experience a great openness and willingness to help each other within the team and between the specialist teams. In this way, everyone contributes to maintaining and further developing G+P's high level of professional competence.»

«With the CPX measurement system, we are on the road all over Switzerland measuring the acoustic effect of road surfaces. During these measurements, I discovered many beautiful places throughout Switzerland and was inspired by the different landscapes: sunsets in the canton of Fribourg, summer days on Lake Maggiore or winding drives up unknown mountain passes. The perfect balance to the daily office routine.»
