Evaluation system for sustainable building for federal buildings
The aim of the Sustainable Building Assessment System for Federal Buildings of the Federal Ministry of Transport, Building and Urban Development is to describe and assess the quality of the sustainability of buildings and structures in their complexity. The last certification according to the Sustainable Building Assessment System for Federal Buildings (BNB) took place in 2015.
criteria
Requirements for the overall system
In addition to the building description, the system must enable the analysis of sustainability.
| Criteria group | Share in the overall rating |
|---|---|
| Ecological quality | 22.5% |
| Economic quality | 22.5% |
| Socio-cultural and functional quality | 22.5% |
| Technical quality | 22.5% |
| Process quality | 10.0% |
Ecological quality
Effects on the environment are researched, taking into account at least the use of resources such as water, energy and land consumption and using data from recognized environmental databases such as "Ökobau.dat". For this purpose, an ecological balance is drawn up and the energy requirement is broken down into renewable and non-renewable energy sources.
Economic quality
As a minimum, an analysis of the costs for the life of the building must be determined. It is the present value of the building costs under the boundary conditions according to Guide to assessing sustainable building . Further criteria are value stability, value development and financial risks.
Socio-cultural and functional quality
Here the aspects of health, user satisfaction, comfort, design quality and functionality and practicality are examined. The points of thermal, visual, acoustic conditions and the airspace quality are evaluated under comfort. Functionality includes accessibility , convertibility and space efficiency.
Technical quality
Ease of cleaning, which measures are to be expected for maintenance, possibilities for recycling and dismantling as well as noise protection are evaluated.
Process quality
The quality of sustainability must be assessed in all phases of construction and planning.
Other rating systems
Evaluation systems from other providers for buildings / structures can apply for recognition based on the same criteria at the Sustainable Building Office at the Federal Office for Building and Regional Planning (BBR) in Berlin.
In June 2015, the BMUB published the assessment system for sustainable small housing construction (BNK). The system was specially developed for one to five-family houses and was used in a pilot phase on 19 buildings. The market launch of the BNK system is intended in particular to further improve the holistic sustainability of small residential buildings in Germany and to increase transparency for builders and buyers of houses. With the BNK system, manufacturers can have the sustainable building quality of their homes independently checked and certified. The BNK system will be further developed by the system providers until April 2016 and then made available as a national quality standard for the sustainability of small residential buildings in Germany.
