We make cities future-proof by decreasing 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.

Olysis calculates heat stress

There are not yet unambiguous regulations on heat stress and many studies are underway to make this subject more concrete. The most common methods for calculating this are solar radiation analyzes and the Universal Thermal Climate Index (UTCI) calculations. By means of these analyzes it is possible to continuously look at the amount of energy that the sun radiates on a surface and the expected conversion to heat in the environment. In order to make cities more future proof we always compute the heat stress and radiation on a project and how to reduce this.

Olysis calculates more than just heat stress

Olysis can calculate more than just heat stress. Think of urban light, shade, heat, sound, but also energy. In a short time, Olysis calculates a large number of design options within the components that fall within the package of urban analyses and building analyses for a fixed price per calculation session. Do you only want to calculate one component, such as heat stress? This is also possible as a single calculation.

Interested in a collaboration? Get in touch!

Calculate the heat stress around the design of your building in advance and avoid failure costs or surprises afterwards. With Olysis you make the city of the future a bit cooler and more resilient. Are you interested in a collaboration? Get in touch with us! We are happy to discuss your wishes.

Let’s see what
our clients say

We build digital solutions for real estate developers, designers, and engineers. Our solutions include smart algorithms that comprise of multiple building technology disciplines. We generate value for decision makers through providing speed, flexibility, and clarity.

OMRT goes further than only technique and innovations, they centralise the client in their approach and fully immerse themselves into it to solve it. – Bijn Worms

With OMRT it is possible to quickly and flexibly predict the feasibility of any design within the dense and complex urban areas. – Arno de Wijn
