During the fifty-odd years since its founding Peutz has executed more than 10.000 commissions, from comparatively small up to very large projects, like Schiphol Airport (Amsterdam). During this period the company and its employees have specialized in a number of related fields.

A major philosophy of Peutz is the integration of experimental and state of the art computational facilities in the consulting practice. Hence the company has had its own laboratories since its founding.

The main fields of expertise are:

Architectural acoustics The acoustical aspects of building design, construction and installation	Room acoustics The acoustical aspects of building design, construction and installation
Electro acoustics Amplified sound transmission transfer and control of the subsequent side effects	Building physics Issues relating to the indoor climate such as sound, vibrations, light, temperature, humidity and air velocities
Physics of the Urban Design The effects of wind, sun/shading and traffic	Noise control Improve the working environment and conditions, through preventing or counteracting problems associated with excess noise and environmental noise
Vibrations control Prevent hindrance, disturbance of equipment, damage to buildings caused by vibrations	Environmental technology The quality of air, soil and water, on micro scale, site scale or entire neighbourhood scale
Sustainability Environmental control, energy consumption, safety and constructional quality of a building	Fire safety Preventing or improving unsafe situations in buildings, optimizing evacuation procedures
Working conditions Optimizing the functional and ergonomical aspects of buildings and industrial activities, specifically as they relate to employees
