Evaluation of existing assessment schemes and outline of a transnational communication and evaluation framework for residential construction towards sustainability


The global objective of the project Longlife - Sustainable, energy efficient and resource saving, residential buildings with consideration of unified procedures and new and adapted technologies - is the development of transnational shared standards for planning, licensing and tendering procedures and their application to pilot projects to enhance the cross-national and economic cooperation for energy efficient and sustainable housing construction. The overall management of the project has the lead partner Prof. Dr.-Ing. Klaus Rückert, Head of Department Design and Structure, Institute of Architecture,
Technische Universität Berlin.

A major challenge on this way is, that the definition, perception and assessment of sustainability properties of a building due to the complexity of the "product" is very difficult even for experts. It is nearly impossible for involved laypersons like clients, buyers, tenants, financiers etc. Serious efforts for innovative sustainability performance of buildings therefore do not necessarily result in better market competitiveness: A phenomenon called "adverse selection" due to a lack of information and transparency.

With this in mind, one important issue to support high quality construction towards sustainability is to enhance the perceptibility of better practice and at the same time the credibility through certification of claimed / displayed quality characteristics. This is exactly, what several national and international certification and labeling schemes for green or sustainable construction aim for.

It is thus the first step of the expertise to undertake a documentation, analysis and discussion of national and international certification schemes for sustainable housing construction. Beside and examination of internationally perceived schemes like BREEAM and LEED or European initiatives like the "Lense" and "openhouse" projects, a special focus will be put on the situation in the Longlife partner countries Denmark, Germany, Lithuania, Poland and Russia. The analysis will cover both, used sets of criteria (content) as well as conceptual and organizational characteristics of the schemes.

In a second step, based on the results of the analysis, a conceptual framework will be drafted and suggestions derived for the implementation of a communication, evaluation and certification scheme for sustainable construction within the longlife project and a possible future "Baltic Sea Housing Development Association" (BASHDA).
