New online tool: Decision tree for making schools more sustainable Nine integrated packages of measures with cost indication

A healthier indoor climate for the school? Economical lighting? Insulating the roof or rather HR++ glass? Or just solar panels? Many school boards want to make their schools more sustainable, but do not know what measures they can best take. The Decision Tree for Making Schools Sustainable is a tool for choosing an approach for making their (existing) school building(s) more sustainable. With well thought-out, calculated, integrated packages of measures.

Nine packages of measures

The Decision Tree provides a package of measures with solutions for energy and indoor climate improvement for school buildings in primary and secondary education from three different construction year classes. There are nine integrated packages of measures, with measures that are mutually coordinated. These are calculated for an intended operating period of 5, 15 or 25 years. With eight of the nine Packages of Measures, it is possible to comply with the Environmental Management Act and with Energy Label C or B and Fresh Schools Class C or B.

Invest smart

In this way, school boards can smartly become more sustainable. The Decision Tree then provides an indication of the required construction and investment costs, options for financing and useful information about tendering procedures.

On 7 February Boot Advocaten, IVVD, design and engineering organization Arcadis and the Netherlands Enterprise Agency (  will organize an afternoon workshop on the Decision Tree. /5666/workshop_manual_sustainability_school buildings/

The Decision Tree developed by

Boot Advocaten and Arcadis commissioned by in the context of the Green Deal Scholen, De

measures and costs are based on expert information and practical experience. Not

only for school boards, but also for market parties and, for example, Bouwagenda and Delta Plan

the Decision Tree offers a practical approach.


To work?

Before a plan for making educational real estate more sustainable is started, it is important that the municipality and school board have jointly established a vision, strategy and development perspective at policy level in an Integrated Housing Plan IHP. The Decision Tree is then useful as an aid. The Decision Tree provides global solutions and global cost indications. It is always important to choose a tailor-made approach for each building and to call in an expert adviser for this. And also important: don't just think about the investment costs, but also about the quality in the longer term and the operating costs. So arrange management and maintenance properly to guarantee energy efficiency and a healthy indoor environment for several years.


Bundling phasing, measures, maintenance and budgets of multiple buildings offers many advantages. It makes an integrated approach, mutual coordination of measures, outsourcing to market parties, smart investments and financing through a bank easier. A large school board can bundle at portfolio level, cooperation can be lucrative for one-person students.


Higher ambitions?

There are also leaders among the municipalities and school boards who are already pursuing more ambitious goals, for example Energy Label A+, Fresh Schools Class A, Energy Neutral or Zero-on-the-Meter. These front runners are at the forefront of an energy transition that is also necessary for the field of schools and will become noticeable. However, insufficient practical data is yet known about this, which is why no Packages of Measures have yet been calculated for this. For the time being, additional investment budget is also required. However, a better match between supply and demand will eventually lead to higher quality and a lower price.
