and application of RT Environmental Declarations
In the Environmental Declaration environmental impacts are itemised under
purchase of raw materials and production. Those impacts include, e.g.,
use of energy, emissions into the air and water and use of natural resources.
The reference in comparisons of alternative building components should
be the functional unit of the end product or building. However, the assessment
of the whole building is not obligatory unless essential with respect
to the choices.
Alternative building components separated from the context of the building
can be compared against each other only for the purpose of the development
needs of companies and industrial sectors. These types of building component
comparisons should be made on the basis of the same required performance
regarding the most important requirements. The impact assessment based
on the eco-profiles of building products and components must be performed
as part of the impact assessment of the whole building. The standard measures
are not mentioned in the declarations but shall be selected for each project.
The declarations neither take a direct stand on the service life of the
product nor categorise products.
Environmental declarations are compiled according to the publication
”Methodology for Compiling Environmental Declarations for Building
Products and Assessing Environmental Impacts of Buildings”.
The information of the declarations is available for several calculation
Skanska Oy: Ekometri
Insinööritoimisto Olof Granlund Oy: BSLCA
Other calculation programs:
Pre Consulting: SimaPro
Keskuslaboratorio KCL: KCL- ECO
The PromisE system was developed in Finland for the environmental assessment
and classification of existing buildings. In the future the system will
be adapted also to new building projects. The system is designed to meet
the different demands arising from three building types: apartment buildings,
office buildings and retail premises. The information of the new environmental
declarations can be used in PromisE. Further details about the program
can be found on the Web site: (www.rakli.fi /a), (www.promiseweb.net)
The information reported in the declarations
ECO PROFILE OF THE PRODUCT
Use of resources
Use of resources includes energy and raw materials. Energy in transportation
and in processes is reported as a total. It is voluntary to report those
figures separately. In processing the information the energy content of
the raw materials is taken into account separately if the material used
as raw material is used also as fuel. The heating values of raw materials
are reported separately. The figures are not included in the energy consumption
of fuels used in the processes. The consumption of raw materials is calculated
without water. The consumption of water is reported in the background
information, but it is not marked in the public declaration.
The emissions are divided into emissions into the air and the water and
into process waste. The figures are reported as accurately as possible
so that the information can be used in different comparisons. N2O-emissions
and other particles are reported if there is a measurable amount of emissions.
Heavy metals are listed and reported as a total if there is a measurable
amount of substances. COD,BOD,Ptot and Ntot are likewise reported if there
is a measurable amount.
OTHER ENVIRONMENTAL ASPECTS
The other environmental aspects focus on construction, risks, service
life, service and maintenance and final disposal. The information can
be given in detail. It is also possible to refer to the LifePlan files.
Construction is divided into transportation, loss on site and emissions
into indoor air. These figures are reported voluntarily. Information about
the emission classification of building materials can be found on the
Web site of the Building Information Foundation RTS, www.rts.fi. The risks
are reported if the product has a safety data sheet.
