Building physics & Acoustics

COMPLEX REQUIREMENTS

Today, construction and renovation are marked by the requirements for energy conservation, environmental protection, comfort, and long-term value stability.

When it comes to planning and renovating buildings, building physics focus intensively on the issues of heat, moisture, noise, and acoustics.

CONSULTING, PLANNING, CALCULATION, AND MEASUREMENT

We provide comprehensive advice on building physics issues and cover a wide range of services.

It ranges from general and specific questions, to thermal building simulations, flow analyses, noise protection in buildings, noise reports, and light simulations, as well as profitability calculations. We also prepare reports and calculations for official submissions.

FOCUS ON ROOM ACOUSTICS

Acoustics are an invisible quality feature of any room. We have in-depth expertise in this area.

We have numerous reference projects for the acoustic design of rooms, buildings, workplaces, and event spaces.
