Sustainable Housing Platform

The Dutch Sustainable Housing Platform (Platform Duurzame Huisvesting) originates from 2011, when eleven members of the platform signed the letter of intent. The members support the strategic goals of the platform, which are to stimulate sustainability in the housing chain by cooperation within the housing sector. The platform members have signed to integrate sustainability within their own organisation, and to activate their network by developing tools such as the Menu Performance Contracts and the Greenlease Menu. These tools support and activate sustainability in the housing chain. To achieve this goal, cooperation within the chain is crucial and is therefore one of the aims of the Platform. The vision of the platform is that improvements the cooperation within the housing chain results in increased sustainable housing.
The following tools of the The Dutch Sustainable Housing Platform are available in English:

EU Policy News

Voluntary Common EU Certification Scheme for the Energy Performance of Non-Residential Buildings

As announced by Paul Hodson also at the latest REHVA Supporters Seminar in October 2014, the European Commission works on the setting-up of a voluntary common EU certification scheme for non-residential buildings. The Commission published a Market study for a voluntary common European Union certification scheme for the energy performance of non residential buildings prepared by a consortium led by Tripple E Consulting (NL). The study gives an overview of existing voluntary schemes and aimed at analysing the demand for a European wide voluntary scheme. The findings were the following:

  • The key factors for scheme selection among a variety of stakeholders were reliability, cost and international acceptance.
  • The main added value of this voluntary EU scheme would be to allow a consistent comparison between non-residential buildings across the EU.
  • It could also contribute to raising the ambition for building certification in some Member States.
  • The study also shows that the voluntary EU scheme should build on CEN standards, start with a pilot phase (e.g. with offices), take a modular approach for energy performance only, and be applied both for public & private buildings, as well as new & existing buildings.
  • Finally, it is recommended that the voluntary EU scheme should use a comparative label design, and that a third party should be responsible for the technical development of it.
New Horizon 2020 calls on energy efficiency

The European Commission opened new calls for proposals on 10 December on energy efficiency (EE). The call covers research, innovation and market uptake actions in 14 different fields – from driving energy innovation through large buyer groups to the development and market roll-out of innovative financial schemes. A total of € 81M funding is dedicated to these topics. The deadline for submission of projects is 4 June 2015. The calls are available here.

The European Agency for Small and Medium-sized Enterprises (EASME) organised an Information Day on the calls for energy efficiency on 12 December 2014 in Brussels. The presentations of the Information Day sessions can be found here, together with the web streams of some of the sessions.

REHVA commenting on CEN EPB Standards

REHVA invites Member Associations and Supporter Companies to send comments on the draft European standards

The Energy Performance of Buildings Directive (EPBD) refers to European standards to be taken into account in the calculation of the energy performance of buildings and systems. The EU puts strong efforts on the development of European standards, which can enable the harmonisation of diverse methodologies and measures for increasing buildings energy efficiency in the EU member states.

REHVA website intranet section was created to share latest drafts of the EPBD technical standards (EN) and technical reports (TR) currently under revision of the above three mentioned committees with REHVA Members and Supporters.

To get access to the REHVA intranet section for EPBD standards – revision 2013-2015, please send your request to Anita Derjanecz at ad(at)

Public enquiry for the majority of the standards has started or will be launched in early 2015. Currently nearly 20 draft standards and their related technical reports are on CEN enquiry, in the field of Heating systems for buildings (CEN/TC 228) or Ventilation for buildings (CEN/TC 156).

The following standards, and the related Technical Reports, from CEN/TC 156 have been selected as pilots by REHVA:

  • Indoor climate input data (revision of EN15251) (prEN 16981-1 and prCEN/TR 16981-2)
  • Ventilation and air conditioning for non-residential buildings (revision of EN 13779) (prEN16798-3 and prCEN/TR 16798-4)
  • AC and ventilation inspections (revision of EN 15240 and EN 15239) (prEN16798-17 and prCEN/TR 16798-18)

Comments on the draft Standards (prEN’s) shall be made by using the official commenting form of CEN. Comments on TR’s are also welcome. Separate sheets for each of the documents shall be used for commenting... The deadline for sending comments on these pilot documents is 31 March 2015. Please send your comments to REHVA office (ad(at) by using the CEN commenting form.

To help you in the commenting, REHVA CEN liaisons have prepared short summaries that highlight relevant questions and point out important issues, which could be addressed by comments.

For all other EPBD standards the commenting procedure is the same.

REHVA members and supporters can also give comments on national level, by attending relevant national committees or using public national commentary on internet. More information is available from National Standardization Bodies.

If you have further questions feel free to contact Anita Derjanecz, Policy and Project Officer, at REHVA Office (ad(at) or Jorma Railio, TRC Chair (jorma.railio(at)

Tool-Kit on Integrated Energy Design


Integrated (Energy) Design: Tool-kit and lessons learned from practice

The IEE-project MaTrID – market transformation towards nearly zero energy buildings through widespread use of integrated energy design – started in June 2012 and ended in December 2014.

Integrated design is a proven method of achieving high-performance buildings that meet the set goals without sacrificing architectural quality or causing excessive costs. Stakeholders start to collaborate within the very early phases of the project.

Therefore, an easily applicable IED tool-kit has been developed. The tool-kit consists of an ID Process Guide, a Tenant Brief, a Client Brief, a Supplement on Remuneration Models and a Supplement on Case Studies and Lessons learned.

The core of the project was the application of the ID process in the building design phase. This was demonstrated in 21 pilot projects among Europe. Demonstration projects have been accompanied from the first idea of the project until the detailed planning phase.

Qualification and accreditation requirements of building energy certifiers in EU28 - BPIE Fact sheet

A well-functioning and reliable EPC system could be the key driver for a market transformation towards more energy efficient buildings. This detailed country-by-country overview of qualification and accreditation requirements of building energy certifiers demonstrates the diversity of approaches across Europe. The quality and accuracy of the certificate and the reliability of the entire EPC scheme depends to a large extent on the certifier's skills. It is of critical importance to include in all Member States' legislation minimum standards for training and experience as well as the need for independent accreditation procedures. A future recast of the Energy Performance of Buildings Directive should include guidance on how to set up an effective and reliable certification process as well as require a more consistent approach from Member States when setting up those requirements.

Setting the 3% target for the renovation of public buildings - status of implementation (2014) - - BPIE Fact sheet

From January 2014, Member States have to renovate each year 3% of the total floor area of heated and/or cooled buildings owned and occupied by their central government. Six months after the deadline to submit a formal notification of article 5 of the Energy Efficiency Directive (EED, 2012/27/EU), BPIE’s latest research synthesizes in a factsheet the current status of implementation. This factsheet is the first in a series that will focus on policy implementation and other aspects of Europe’s building stock. Download the fact sheet. Source: BPIE
