Urban Physics analyses

Our cities are getting fuller and fuller. Available building spaces become more scarce and still we need to fulfill the demand. We need to build! We assess and optimise urban plans in sustainable and efficient manners.

Sunlight and shadow

Many new construction or transformation projects have an impact on the sunlight hours and cause shadow falling on the immediate environment. Shadow and sunlight are different at every time of the day and year. That is why these topics must be carefully considered for each design in relation to the context and within the project itself.


Every spot in the urban environment is currently being filled with new apartment complexes and office buildings. Often ‘good’ locations are already taken and the leftover locations are close to train tracks, busy roads and around industry. Result: more chance of noise nuisance.


Wind nuisance is an increasingly common problem in the Netherlands as we build more and higher. However, wind nuisance studies are often expensive and lengthy. That is why wind calculations are not yet carried out on a large scale and for every project.

Radiation and heat-stress

Every summer we notice it more and every year it seems to get worse; the heat problems in the city. Cities store heat due to the amount of stone and the lack of greenery and shade, so-called heat islands. On warm days, this makes for a difference of 12 degrees Celsius compared to a village in the countryside. In order to make our residential areas future-proof, we must properly integrate the subject of reducing heat stress in every design we make.

View quality

It is an underexposed topic but one that has the most impact on the ultimate human experience; view quality. Aesthetical aspects are very difficult to quantify, but what you can or cannot see in a design can be quantified. By means of sightline analyzes that can be measured 360 degrees vertically and horizontally we can make clear how much view quality there is in the plan in every design.

Interested in a collaboration? Get in touch!

Calculate the urban physics in every design of your plan in advance and avoid failure costs or surprises afterwards. With Olysis you can quickly and easily improve your view quality early on in your design. Are you interested in a collaboration? Get in touch with us! We are happy to discuss your wishes.
