Environmental and health related criteria for buildings - ANEC

IBO - Environmental and Health related Criteria for Buildings
Energy-related indicators are the following:
Energy demand (primary energy non-renewable) within life-cycle 37
One sub-criterion of “Ecological Quality” is the primary energy demand for construction,
operation and disposal of the building assessing the use of non-renewable resources.
In addition to the construction materials for the building envelope and interior completion,
heating systems are balanced whereas heat distribution and dissipation systems as well as
further building services installed are excluded from the ecobalance. The operation phase
comprises maintenance and renovation as well as supply with energy carriers within a period
of 50 years 38 . For disposal, the following material groups are taken into account: metals,
mineral building materials, materials with heating value, heat generation systems, materials
disposable to construction waste landfills or household garbage dumps.
This life cycle assessment of the building is not only limited to resource indicators but is also
required for selected impact categories such as global warming, ozone depletion,
photochemical ozone creation, acidification, nutrification, and risks for the local environment.
Share of renewable resources 39
The system boundary is the same as mentioned above. Renewable resources are biomass
systems, solar hot water, photovoltaic, geothermal resources, hydro power, wind turbines,
secondary fuels (e.g. tyres, waste oil, waste plastics), waste incineration.
Within the main category Economic Quality the life cycle approach is extended to Life Cycle
Cost (LCC).
Traffic-related Energy Aspects
The site quality is not included in the final grade but is presented separately.
Emissions from individual traffic are not directly assessed. Access to public transport and
cycle paths is evaluated by following indicators: time to reach the next (main) railway station
via footpaths (assessment ranges from less than 3 minutes till 40 minutes as minimum
requirement), access to the next public transport (bus, local train, tramway) (urban: 1 till 5
minutes; rural: 2 till 10 minutes), site connection to cycle and footpaths (direct connection,
average access). The quality of public transport (timetables) is not yet included, but will be
integrated in future versions.
Infrastructure criteria relate to proximity (300 - 1000m) of restaurants, shops, parks,
educational and community services, medical care, leisure facilities.

38 In the DGNB criteria for residential buildings (draft version May 2010), the expected life-time has been derived
from office buildings, but may be even higher due to less changes in utilization and longevity of construction
materials. In ON EN 15804 “Sustainability of construction works – Environmental product declarations – Product
category rules”; the period of consideration is extended to 100 years.
