The database of Bureau CRG (acronym for verification and registration of declarations of equivalence, the original task) publishes the verified declarations of equivalence of products or systems applied in the building and services industry to conserve energy. On request of manufacturers/importers/suppliers a recognised quality declaration based on a Dutch Assessment Guideline or standard DOP’s (Declarations Of Performance according to Regulation 305/2011) can be incorporated in the database or referred to, but also other performance declarations according to test or calculation methods described in the Dutch energy performance standard(s). The database comprises a.o.mongst others, declarations or references to (high efficiency) boilers, solar heaters, window frames, glass, insulation materials and heat pumps
A board of independent experts verifies whether the claim as issued by the manufacturer/importer/distributor/energy service company , is justified. The claim can be stated as:
When accepted by the Bureau CRG as justified , this verified declaration of equivalence, DOP or a declaration of the efficiency of the district infrastructure (EMG) will be included in the database.
For other performance declarations the verification is executed as well if the claimed performance isn’t based on an harmonized standard or European Technical Assessment Authority (EOTA ) nor on a Dutch Assessment Guideline or a determination method described in the Dutch Energy Performance standard(s). If the claimed performance in the declarations cannot be used in the standard Dutch Energy Performance calculation this performance has to be transformed to a value that can be used in the applicable Dutch EP calculation method (domestic/non-domestic; new buildings/existing buildings). The Assessment Board verifies this transformation.
A Declaration of Equivalence is a written declaration, accompanied by a report in which is demonstrated that alternative construction systems and/or products which aren’t appreciated in the Dutch standard energy performance calculations (NEN 7120, ISSO 82.1 (NV 7120) of ISSO 75.1) offer at least the same safety, health protection, usability, energy performance and environmental protection as is strived for in requirements in the Building Decree and subsequent standards. Local authorities verify in case of a building application whether the building material or construction part or system with such a declaration of equivalence complies to the requirements of the Building Decree.
A recognised quality declaration (RQD) is a certificate, provided with a mark as appointed by the responsible national Authorities( in the Netherlands : the Ministry of the Interior and Kingdom Relations) Ministry . ,This RQD has to be issued by a notified body. A product with this RQD is supposed to comply with the requirements in the Netherlands Building Decree and should be accepted by the local authorities as sufficient proof of compliance.
In case a manufacturer wants to place a construction product on the European market, which product is subject to Regulation (EU) No. 305/2011 of the European Parliament and the Council of 9 March 2011 , this product will be subjected to an harmonised standard or an European Assessment Document (EAD). (hereafter indicated as the Regulation) The manufacturer has the obligation to produce a Declaration of Performance (DoP) for such a construction product. Local building authorities shall accept these declarations. . Only declarations that comply the Assessment and Verification of Constancy of Performance (AVCP’s 1 and 2 ) can be incorporated in the database without any check by the Assessment Board.
A declaration of performance is a product declaration referring to a determination method as described in a regulation which could also refer to an accepted standard or annex of such a standard, e.g. the energy performance standard. For energy performance calculations for existing or new buildings it is restricted to qualities or characteristics that can be used in the applicable calculation method. This category can contain DOP’s with AVCP system 3 and 4 according to Regulation 305/2011 as well if the underpinning of the performance is given, e.g. factory production control measurements.
Another declaration type describes the energy performance of the district energy infrastructure. It describes for instance the performance of a district heating system where waste heat of industry is used or heat is provided from renewable sources, e.g. biomass incineration. The primary energy efficiency of such a system can be better than that of other common heat sources.
Local authorities - and in the future (dependent on future legislation) the building quality assessor – use the declarations in the database (declarations of equivalence, recognised quality declarations, CE- and other DOP’s, district energy infrastructure declarations) to verify calculations of the Energy performance of a new building. Because the number of construction products and systems in the database, they can quickly find objective information on one site.
Independent energy performance of buildings certification experts (EPA-consultants) need the declarations for the calculation of the energy performance to produce a EP-certificate for existing buildings. Deviations of default values for construction or system performances only are allowed if verified declarations for these deviating performances are available in the database. These declarations can be used for consulting on energy conservation as well. In the near future also for building applications for new buildings accredited experts may only use verified performance declarations for construction parts and systems.
If property owners, investors and real estate managers seek to improve the energy performance of their buildings, they can use verified declarations to search for construction products or systems that contribute to energy efficiency. For housing corporations this can be relevant because the energy performance certificate can be decisive for the rent to be charged.
The Declarations Assessment Board verifies the validity of the claim of a manufacturer/importer/supplier in the field of energy performance of a construction product or system. The Board follows a well-documented procedure. The Declarations Assessment Board is composed of experts in the fields of building physics, building services, standardization and building application procedures for local authorities. They have no relations with manufacturers/importers/suppliers and shall judge impartial.
The Netherlands government has laid down in the Building Decree 2012 which energy performance requirements for new buildings. For the calculation of the energy performance the Building Decree refers to a national standard to determine the energy performance. This standard prescribes the calculation of the characteristic energy consumption and the derived indicator(s) that are bound to a maximum in the Building Decree. Products or systems that outperform the default values included in this national standard or innovative constructions or systems with comparable performances, can contribute to improve the energy performance indicator(s). The energy performance of these products and systems have to be determined and verified.
The governmental Energy Performance of Buildings Decree prescribes the issue of an energy performance certificate for buildings (or a building) which are constructed, sold or rented out to a new tenant. For housing corporations it can be of interest asses an extended Energy Indicator (Energy-Index) because this indicator is appreciated in the housing rating system, the system that determines the height of the rent of social housing. Independent energy performance certification experts (EPA-consultants) may deviate from default values for construction or system performances only if verified declarations for these deviating performances are available. They find these verified declarations in the database.
In the database verified declarations of performance and declarations of equivalence for products and systems for the construction and building services can be found of which the Declarations Assessment Board has accepted. A large number of products that contribute to the energy performance is included in the database. The database comprises of about 1.000 declarations of more than 200 manufacturers. Due to further development of products and systems and new innovations this number increases every month.
Searching the database is quite simple. The user can filter on several characteristics. The declarations once placed in de database will be kept also in the case the products/systems aren’t supplied any more. These old declarations are needed to determine energy performance of these products/systems still applied in existing buildings.
The database is improving its search functions by feedback from users. That invokes more users to use the database In 2016 the database was consulted 68.000 times by 17.000 unique users. In 2017 the database was frequented ….000 times and in 2018 ….., which indicates an increased use.
Users of the database – local building authorities, private building design assessors, independent energy performance certification experts or property owners/real estate managers – highly appreciate verified objective information on the energy performance of products and systems. With that information they calculate, assess or improve the Energy performance indicators for new (EPC/BENG) or existing (Energy-Index) buildings.. Manufacturers, importers and suppliers can use this verification in their marketing of construction products and systems.
By incorporation of their products and systems in the BCRG database manufacturers, importers and suppliers present the performances in an uniform way that enables good comparison. Users profit from this uniform presentation of information on e.g. (high efficiency) boilers, solar heaters, window frames, glass, insulation materials and heat pumps in one database. It enables simple assessment and consult. Property owners and real estate managers seeking to improve the energy performance of their buildings can find which products or systems best contribute to energy conservation.
The manufacturer/importer/supplier pays a yearly fee for maintenance and management of the database. Manufacturers/importers/suppliers which apply for declarations of more than five products will get a rebate.
The Declarations Assessment Board verifies the declaration of equivalence, the standard (CE) DOP or energy performance determined DOP or the performance declaration of a district infrastructure together with the supporting underpinning. This will be based on the boundary conditions of the existing standard NEN 7120 (new buildings), ISSO-publication 82.1 (existing dwellings) and/or ISSO-publication 75.1 (existing non-domestic buildings). The assessment can take less time if information is complete.
For quality declarations without third parties involved in the production phase, e.g. DOP’s according to Regulation (EU) No. 305/2011, AVCP systems 3 or 4.
A declaration of energy performance of district infrastructure (EMG) according to NEN 7125 has to comply specific requirements. Contact us for these specific requirements.
The Assessment Board follows prescribed procedures for the verification of declarations. The Assessment Board judges the safeguard of the claimed performance during lifetime of the construction/system.
The procedure is designed in consultation with the Central Board of Experts (CCvD) of Foundation for Quality Assurance in Building services in the Netherlands (installQ). Manufacturers, importers or suppliers that don’t agree the procedures followed by the Assessment Board can appeal to this Central Board of Experts. The verdict of this Board is binding.
