Organisation NMD

Stichting National Environmental Database (NMD) was founded as independent organisation to manage and maintain the Assessment Method and accompanying database for assessing the environmental performance of construction works

• This uniform assessment method has been designated by the government in building regulations as an instrument to calculate the Environmental Performance of Buildings (Environmental Performance of Buildings). This Assessment Method supports policies on climate, raw materials and waste, and circular construction. The Assessment Method and connected database are also designated within the framework of government policy on sustainable procurement and tendering.

  The Assessment Method is in line with European visions and is based on the total life cycle of construction products and building installations that are processed and used in buildings and civil engineering projects. The method also considers reuse, renewability and recycling.

  The Assessment Method is based on the total life cycle of construction products and building installations that are processed and used in buildings and civil engineering projects. The method also considers reuse, renewability and recycling.

  Data are assessed in an unambiguous, controllable way and can be used directly in the design and implementation process. This creates a level playing field.

  The Assessment Method is used in the public domain as well as by private organisations to categorise sustainable real estate, e.g. via BREEAM, GPR, etc. The method is explicitly used for assessment at building or project level, and not to compare products.

Netherlands Policy Committee on Environmental performance (BMNL)

Eighteen parties are represented in the BMNL, divided into three groups, clients (public and private), data suppliers (industry suppliers) and data users (architects, engineers, software tool/calculation tool owners, builders and installers).

The BMNL advises on the Assessment Method and content aspects of the NMD system and safeguards the NMD’s independent and unique role with respect to energy performance of buildings or civil engineering structures in the construction sector. BMNL represents the interests of various stakeholders, working together towards a cohesive and consistent system. BMNL has the right to consent on such things as rates, the annual plan, licences and the Assessment Method (following consultation with the Ministry of Economic Affairs). The Technical Committee (TIC) advises the BMNL and comprises experts acting in their personal capacity.

In order to carry out its tasks, it is important that the committee has a balanced composition and that its members are competent and knowledgeable. The TIC chairperson attends committee meetings in an advisory capacity to ensure a good links between BMNL and the TIC. The committee members should represent a support base and are appointed for a period of three years. Reappointment is possible. The committee members have to sign a confidentiality agreement if confidential product data are discussed in the committee. An independent chair has been appointed to safeguard meeting efficiency and prevent a conflict of interests. BMNL meets four times a year in the first instance. A decision will be taken later this year as to whether this is sufficient.

Technical Committee (TIC)

The TIC members are experts. The aim is for a maximum of 8-10 members, at least 60% of whom are experts in LCAs for buildings and civil engineering structures. The remaining 40% will be filled by representatives with Life Cycle Assessment (LCA) and/or Energy Performance of Buildings (EPB) knowledge from construction sector parties. The members and chairman will be nominated by the Environmental Policy Committee based on competencies. The TIC meets three to four times a year. TIC members contribute knowledge but also benefit from their direct involvement through knowledge exchange. The committee members are not paid to attend these regular meetings. However, a budget will be available to hire personnel for execution of specific regular tasks. Projects may also be formulated in a project plan and funded separately.

The current members of the TIC are:
