GPR calculation

Apply a GPR building calculation to your project

GPR Gebouw is a practical method for making the sustainability of buildings measurable. It provides clear insight into energy use, material choices, health and future value. In both the public and private sector, GPR serves as a powerful tool for designing and building sustainably. The method is developed specifically for the Dutch market by W/E Advisors, who also manage the GPR Material tool.

GPR consists of six chapters:

Each chapter is rated on a scale from one to ten. In our projects, we aim for a minimum score of eight point five across all categories.

During construction and at delivery, GPR is also used to verify whether the building meets the defined sustainability requirements. After completion, GPR can continue to support monitoring and optimisation of energy use and other sustainability performance.

If you have drawings and can explain your plan to us, we are always happy to explore the possibilities at no cost.

With a strong score across all eight chapters, a tax benefit can be obtained from RVO through the MIA Vamil scheme. For the current conditions, always refer to the Milieulijst.

If you are more interested in BREEAM or WELL, we can support you with that as well.

Building Revolution applies GPR in many projects.

GPR Gebouw general explanation

GPR Gebouw is an innovative digital tool designed to measure and evaluate the sustainability of buildings in depth. This advanced assessment method is suitable for both residential and non residential projects and originates from the Municipal Practice Guideline developed in 1995 by the Municipality of Tilburg in collaboration with W E Consultants.

GPR explained in a nutshell

GPR, short for Municipal Practice Guideline, is an advanced method for measuring and evaluating the sustainability and performance of buildings. It includes GPR Gebouw, which assesses a building across themes such as energy, environment, health and user quality. This assessment is carried out by a certified GPR Expert or Assessor, who provides the calculation and certification. The GPR score ranges from one to ten and offers clear insight into the sustainability level of a building. A higher score, such as seven, eight or even nine, reflects stronger sustainability performance. Receiving a GPR certificate confirms the sustainability value and demonstrates compliance with GPR requirements. GPR focuses not only on sustainability but also on circularity and building installations, making it a valuable tool for assessing real estate performance.

GPR Energy

First, the source of energy can be evaluated. The use of sustainable and renewable energy sources, such as solar, wind or biomass, can significantly improve the energy performance of a building. Next, building insulation and heat recovery options can be considered. Minimising heat loss and making optimal use of waste heat can further enhance energy efficiency. Energy efficient equipment and lighting also contribute to a higher GPR energy score. Investing in energy efficient technologies can often be financially beneficial in the long term. For companies with a BENG requirement, the BENG calculation is carried out in accordance with NTA 8800. For companies with an industrial function, the assessment is completed without BENG, supported by dedicated questionnaires.

GPR Environment

The Environment chapter is closely linked to the MPG. Fortunately, Marco van Brink is our specialist in this field. He knows better than anyone how to improve the environmental performance and GPR score through the methods outlined below.

Material

A key approach is reducing material usage. This can be achieved through smarter design and construction, avoiding unnecessary elements. Examples include optimising structural layouts, limiting unnecessary partitions and reducing the use of concrete and steel. Using sustainable materials is equally important. Selecting products with a low environmental impact and a long lifespan helps lower the MPG. This includes recycled materials, renewable resources and products with low emissions of harmful substances. Reusing materials can also have a strong positive effect on the MPG. Reuse from demolition or renovation projects can lead to significant savings in energy and raw materials.

Water

Efficient plumbing fixtures, such as water saving taps, showerheads and toilets, can be installed to reduce water consumption without compromising comfort. Rainwater can be collected and reused for toilet flushing, garden irrigation and cleaning. This reduces the demand for potable water in non potable applications. Landscape design can also play an important role. By selecting plants suited to local conditions and using water efficient irrigation systems such as drip irrigation, water use can be reduced significantly.

Space and nature

Nature inclusive building integrates the needs of people, animals and plants into the design of buildings and their surroundings. The aim is to promote biodiversity, improve habitats for flora and fauna and create a pleasant and sustainable living environment for people.

This approach considers the specific characteristics of local ecosystems. Green roofs and facades can offer space for plants, insects and birds. Nesting boxes, insect hotels and bee friendly plantings can also be incorporated.

Sustainable materials and construction methods further support nature inclusive building. Avoiding harmful substances and minimising environmental impact contribute to a healthy environment for people and wildlife.

GPR Health

The Health chapter consists of four subchapters: acoustic comfort, air quality, thermal comfort, light and visual comfort

As a foundation, healthy indoor environmental requirements must be established and achieved. This includes ensuring proper ventilation and air exchange, avoiding harmful substances in materials and products and maintaining comfortable temperature and humidity levels. Attention should also be given to noise levels and reducing ambient sound.

Daylight and outdoor views are essential for a healthy living environment. The design and layout of the building should therefore provide sufficient daylight and pleasant views of the surroundings. This can be achieved with large windows, open floor plans and thoughtful positioning of rooms.

A healthy lifestyle can also be supported through a user friendly building layout and movement friendly ergonomic spaces. For example, stair use can be encouraged by creating inviting staircases and placing them in logical, visible locations.

Finally, a healthy living environment is strengthened by choosing materials and products that are sustainable and safe. This includes considering the environmental impact of production and transport, as well as opportunities for reuse.

GPR Use Quality

The Use Quality chapter consists of four subchapters: accessibility, functionality, technical quality and social value

Comfortable and flexible layout
It is important to ensure that the layout of the building suits the needs of its users. Provide sufficient space, a logical flow and flexible areas that can be adapted easily to changing requirements.

Durable materials and finishes
Choose long lasting materials and finishes that require minimal maintenance. Consider good insulation, high quality finishes and products with a low environmental impact. These elements improve both comfort and the overall quality of use.

Sufficient daylight and good ventilation
Ensure adequate daylighting and proper ventilation throughout the building. This supports the comfort and well being of the occupants. Consider energy efficient systems such as LED lighting and mechanical ventilation with heat recovery.

Accessibility for all
Ensure that the building is accessible to people of all ages and abilities. This includes wide doors and hallways, suitable elevator capacity and good wheelchair access. A building that is accessible for everyone contributes to a positive user experience.

Good acoustics and sound insulation
Good acoustics are essential for a comfortable and user friendly environment. Provide effective sound insulation between spaces to reduce noise pollution. Soundproofing materials and smart acoustic design can significantly improve the experience for users.

GPR Future Value

The Future Value chapter consists of four subchapters: present quality, building adaptivity, climate adaptivity, experience value.

Choose adaptive circular design
Circular design is essential for the long term value of a building. This involves using materials that are reusable, recyclable or biodegradable. Applying these principles increases future value while reducing environmental impact.

Choose energy efficient and sustainable installations
Energy efficient and sustainable installations help reduce energy consumption and contribute positively to future value. Examples include solar panels, heat pumps and energy efficient lighting.

Consider the lifespan of the building and build climate adaptive
The expected lifespan of the building should be taken into account from the outset. This means designing a strong and durable structure that can withstand wear over time. A design that anticipates future climate conditions and long term use strengthens the building’s future value.

Design flexibly while preserving amenity value
Flexible design supports future value by allowing the building to adapt to changing needs and trends. A flexible layout ensures the building remains usable and relevant for a longer period. At the same time, the design should respect the amenity value of the surrounding area and its neighbours.
