Our modules

Location analysis


Ostate Module 1 - Location analysis

The Ostate location analysis module brings together public data from all addresses in the Netherlands in a single overview. As a result, Ostate prepares all needed information in a central way to start and design a project easily. This allows you to see clearly which preconditions and limitations there are at and around the location.

Plot the contours and boundary conditions of your project with Ostate

Based on this data, Ostate can then generate the correct contours of a plot. This allows you to determine at urban planning level what the maximum envelope looks like. You can also use it to set out an existing plan vision or image quality plan.

Ideal for a municipality or other party that wants to write a plan and discover in advance what impact the request will have. With this module they can quickly and easily see to what extent they can make the contours, building lines or maximum heights of a plan.

Urban Massing


Ostate Module 2 - Urban Mass Study

The Ostate mass study module generates all possible design variants at Gross Floor Area level and explores the shapes that could fit on the plot in relation to the context. This means that Ostate takes account of storey heights and the placement of certain functionality on a vertical and horizontal level, but does not yet determine the final floor plans within the building.

In this module, Ostate takes into account the urban development preconditions and the information from the first module and context data.

Ostate provides flexibility and efficiency in the design process

Within the set preconditions and urban development requirements of Module 1, Ostate generates every shape option of the plan. This can even amount to hundreds of variants. Ostate therefore uses a convenient online dashboard that can quickly display all these variants and in which you can easily select afterwards based on certain criteria. In no time you will receive feedback on all possible variants and you will see the measured and calculated information per variant.

You can always select the best variant yourself in our dashboard. Even if you change your mind or the preconditions change later in the process, you can fall back on this dashboard and select a new variant that does fit.

Combine the Mass study with urban planning Olysis analyzes

Ostate module 2 - Urban planning mass study uses the analyzes from Olysis at an urban planning level. This way, you can immediately see per variant what influence the design has on the environment.

Conceptual Floorplanning


Ostate Module 3 - Structure designs (program integration)

The Ostate conceptual floorplanning module fills in a building shape based on the desired program. Ostate takes into account design principles, structural typologies and the building code when doing so. Based on this plan, you can quickly make an initial estimate of the ratio between Usage Area and Gross Floor Area (GO / GFA ratio) and whether a project will be feasible.

Ostate generates conceptual designs based on your wishes

In order to make an optimal structural design, Ostate must be fed with the right knowledge and information. Firstly, this step always requires a mass that is divided into floor parts, this comes standard from Ostate Module 2 - Urban Planning Mass Study, but can also be supplied separately as a 3D file. You can also think of the following parameters:

Ostate provides flexibility and efficiency in the design process

Based on these parameters, Ostate can fill in a 3D model itself. Ostate takes into account a number of building requirements such as walking distances, minimum widths, access principles and more (request the current status of the standard integration). In addition, room reservations are also made in this module for items such as stairwells, elevator shafts, vertical pipe shafts, balconies and storage areas.

Based on the input and requirements, Ostate generates a wide range of variants of layouts and automatically draws them into the 3D model. This can even amount to hundreds of variants. Ostate therefore uses a handy online dashboard that can quickly display all these variants and in which you can easily select afterwards based on certain criteria. In no time at all you will receive feedback on all possible variants and you will see the measured and calculated information per variant.

You can always select the best variant yourself in our dashboard. Even if you change your mind or the preconditions change later in the process, you can fall back on this dashboard and select a new variant that does fit.

Test your structural design with architectural Olysis analyzes

Ostate module mass study uses the analyzes from Olysis at an urban planning level. This way, you can immediately see per variant what influence the design has on the environment. See what analyses Olysis can do on building level.



Ostate Module Parking

The Ostate Parking Module generates automatic parking maps. Ostate takes into account design principles, access typologies and the parking standards from NEN2443. No more endless signing in and checking whether you meet the parking standard, Ostate shows you the best variant in a few minutes.

Ostate generates parking layouts based on your wishes

In order to achieve the correct parking layout, Ostate must be fed with the correct knowledge and information. Based on the parameters and the ground plane, Ostate automatically creates a parking space with carriageways. All facets are connected and linked so that the lane widths always match the parking angle rotation.

Module parking can work integrated with the other modules

A parking space under a building often has a major impact on the design of both the building and the parking lot. It is a complex game in which the aim is to maximize efficiency. By combining Module 3 - Structure design and Module 4 - Parking you can make this game easier.

This module is built in such a way that the parking layout automatically takes into account the structural parts of the building above it. Columns, walls and risers are taken into account, each with its own set of rules.



Improve the acoustics with Olysis

Do you recognize that? You went to bed just in time and suddenly the neighbors start a rave late into the night, or your upstairs neighbor has downloaded an app that allows you to exercise at home ... Nothing is more annoying than hearing the neighbors or others in a building, noise is one of the primary causes of stress or unrest.

Reverberation times and contact noise

Olysis simulates internal sound to prevent this kind of nuisance and even to be able to optimize the sound to a very comfortable level. Olysis helps to shorten reverberation times and minimize contact noise according to the standards of NEN 5077, NEN-EN 12354-6 and NPR5071.

Olysis does this by looking integrally at the use of acoustic materials and their application and positioning.



Improve your productivity by improved comfort with Olysis

Nowadays we spend almost 90% of our lives in a building. This is why a good indoor climate in which you feel comfortable is highly important. Good comfort makes you literally feel more comfortable and can even raise your productivity. On the other hand, poor comfort can make you feel much worse and even have such an impact that it causes health damage. Yet not all buildings are comfortable and we still often assume the minimum delivery level specified in the building code.

More comfort for the same price with Olysis

With Olysis we calculate comfort based on temperature, ventilation draft and freedom of vision. This allows us to predict how a person will generally feel in a building. Yet every person is different and comfort is a very subjective concept. With our system we therefore look at the comfort per season, per location in the building and even per type of person. We base the scores on existing literature and research on this subject.

Because Olysis can approach comfort parametrically, this allows us to properly weigh comfort against, for example, the extra investment or sustainability of the design. In many cases this even means that no extra investment is even required to still gain comfort.

Olysis prepares you for the WELL, BREEAM and LEED

To give comfort a testing framework, various standards have been written within Europe or even worldwide. Olysis has integrated these frames as standard and can thus provide direct feedback on the quality of comfort.

Sustainability and CO2


Olysis reduces the footprint of any design

Sustainability is a broad concept that has many aspects and disciplines. Unfortunately, the term sustainability is often misused to give a project a better image. It is therefore necessary that sustainability is also made concrete within real estate in order to provide insight into the impact of this sustainability, we aim to do just that for each project.

With Olysis you make sustainability measurable

We use the standard method Environmental Performance of Buildings (MPG) to calculate the CO2 footprint of the materials used in a building. These materials have been assessed by experts through a Life Cycle Analysis (LCA) for the CO2 score for making, transporting and maintaining them.

But with only the footprint of the materials of the building you do not have a total overview. You can use very sustainable materials that, for example, do not efficiently handle the energy supply within the building. In that case, your building could emit a lot more CO2 in the long term than a building with non-sustainable materials, but with a higher energy efficiency.

This is why Olysis has, in addition to the MPG, also developed the Integrated Performance Buildings (IPG) on the basis of research from TNO and TU Delft. We calculate both factors and combine the total impact of a building over its lifespan.

By calculating quickly and flexibly, we always come a step further

Olysis can very quickly calculate all kinds of different scenarios, including for material use and energy consumption (see also page Olysis - energy). This allows us to investigate which materials score best on sustainability. In this way we make this item concrete in a clear way and we give guidance to the ambitions of our customers.



Buildings consume 40% of the world's energy

Almost 40% of the total CO2 emissions in the world come from buildings. Many buildings have been built a long time ago when other or even no requirements for energy consumption were set. Now almost 97% of the buildings in the Netherlands will have to be renovated up to 2050 to meet the climate agreement requirements.

The warmer landscape of requirements and rules for energy calculations

The subject of energy has been the victim of legislative changes, changing regulations or misconceptions about energy-efficient measures for several years. What started as a regulation from the EPBD (Energy Performance of Buildings Directive) was the EPC (energy performance coefficient), but it continued as the EPA (energy performance advice) and now the BENG 1, 2, and 3 (Nearly Zero Energy Buildings). It uses the NTA8800 standard as a guideline, just like the BREEAM.

So indeed all in all very confusing and logical that things might go wrong…

Olysis calculates the real energy balance, but also tests against the standards

Ultimately, an energy calculation is a balance of physics in which the energy entering the building is compared with what goes out. The standards are there to "normalize" these and to draw an equal denominator across the country. Olysis therefore first calculates the "real" value of the energy consumption and generation in a building based on physics, and then compares how this translates to the right norm and regulation. In this way, you can both prove that the design meets the requirements but we also allow you to estimate the future energy bill.

Light and Daylight


Optimize daylight with Olysis

Light is one of the most important elements in the built environment because it literally makes everything around us visible. With light you can evoke many different feelings or even make people more productive. Light calculations are therefore also an important chapter within Olysis.

With Olysis we do both daylight and artificial light calculations.

Calculate daylight according to the standard

For daylight, regulations require the correct amount of light entering a home through a window and the reduction of light glare. Olysis does both calculation methods automatically according to NEN-EN 17037.

But in addition to the official Dutch regulations, we can also steer on quality with Olysis, these methods are requested within the WELL or BREEAM standard.

Our parametric system allows you to easily test different compositions of number of windows with window sizes and placement, but also combined with different artificial lighting systems. By optimizing these two against each other, you can develop an effective lighting plan very quickly.



Photovoltaic Panels (PV panels) generate an optimal yield through good design by Olysis

In new construction projects, energy-yielding systems are often added as standard to the facades or on the roofs, but there are also many unused roofs in the Netherlands that may still be suitable for this purpose. With Olysis we calculate the possible quantity of PV panels and the optimal placement and angle to the sun for both existing and new buildings. We can take the environment into account and immediately provide insight into where the tipping point of efficiency and yield lies between the number of PV panels to be purchased and their energy generation.

Sunlight and Shadow


No shadow nuisance with Olysis

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.

There are only guidelines for sunlight and shade

There are no laws and regulations from the government for this, but most municipalities use the TNO standard ( We calculate our plans based on this standard, but can also easily adjust this unit of measurement to your own standard or preference. For example, we can use the "strict" or "light" TNO standard as a unit of measurement, but also local or own criteria. We include the environment in 3D as standard and can measure the effects on both our own project and the environment.



Prevent noise pollution with Olysis

The Netherlands is getting fuller and fuller. Living and working space is becoming more scarce and yet more of both is needed. So build! 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. In order to prevent noise nuisance for residents and workers, noise is inevitable. That's where Olysis comes in.

Take sound reducing measures in advance

Olysis provides advanced insight into how living and working space should be arranged to optimise sound in- and around buildings. By integrating this within Olysis, you can take soundproofing measures in advance. Advantage: you avoid unnecessary measures (and therefore failure costs) afterwards. That is how Olysis helps contractors, developers and architects.

“Wet Geluidhinder” - Noise regulation

With Olysis we calculate noise in the area according to the NEN5500 standard for sound insulation. This is in line with the “Wet Geluidhinder” (Wgh). This law specifies to what extent noise-sensitive buildings may be "bothered" by certain noise sources, such as:

  • Road traffic (not weighing 30 km per hour)

  • Railways

  • Industrial areas

If you calculate your design in advance with Olysis, you can be sure that it complies with the Noise regulations.



Wind calculations in a faster and easier way with Olysis

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.

We offer wind nuisance surveys that are super fast, less-expensive and accurate. Like all other calculations from Olysis, Wind analysis is part of a total package and is always included in every project.

How Olysis calculates wind

We use two calculation methods:

  1. the first is a super-fast check to determine the effects of wind with different design options and wind nuisance measures, this analysis takes only seconds per calculation and is approximately 85% accurate (see also this article).

  2. the second type of calculation we perform is a regular CFD calculation, as you know it. This takes a longer time and that is why we only do it on a fewer number of variants, when it is really needed and to zoom in on a more accurate level.

We always calculate wind in line with the standards for wind comfort and wind nuisance, this standard is NEN-8100. We present our results as a gradient on the measured surface and we do the calculation in both 2D and 3D. We can read the results both in figure and in number and we can indicate various limits and exceedances in the visualisations. This way you can easily see at a glance where the wind climate is good or critical. We use the input data for the wind climate as measured by the KNMI.

Radiation and Heat stress


To make cities future-proof, heat stress must be analyzed

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.

View quality


View quality gives the user experience

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.

Olysis measures view quality from and to certain points or the sky

You may have booked an old hotel room afterwards where you have a small window with a different facade pontifical on the other side. The first thing you do is look through the window and see how much of the sky you can see. This is also how you can measure view quality; how much of the sky can you see from any point in a room?

On the other hand, you can also measure view by focusing on objects whether you can see them or not, and in what capacity. This way you can put objects in the spotlight in every design or create privacy where necessary.
