You can assess the building performance on the 3 dimensions of sustainability. But how does this relate to all other assessments of sustainability: to the sustainability of the infra structure, the transport and energy system, etc? And where to position a sustainability assessment of management and decision processes? How does this relate to the building assessment as defined in the scope the CEN TC 350 standards?

Sustainability is assessed by measuring the aspects and impacts of the
building/works and the building/works processes:

• Without meeting the technical needs there is no sustainability

Basic Requirement for
Construction Work #2:
Safety in case of fire
OK: safety for building users.
But fire does not allow
the most sustainable products
to pay off their sustainability

I am Chris Hamans and have my company ESC, European Sustainability Consulting.This presentation reports on the status, background and development of the European CEN TC350 standards: a suit of standards for assessessing the sustainability of construction products and buildings.
The CEN TC350 standards form of a suite of the European Standards, written by CEN/TC 350, that provide a system for the sustainability assessment of buildings using a life cycle approach.
The sustainability assessment quantifies impacts and aspects to assess the environmental, social and economic performance of buildings using quantitative and qualitative indicators, both of which are measured without value judgements.The purpose of the suite of standards is to enable comparability of the results of assessments.
But first this:If a building does not meet the needs for use, then the building and all products and materials in the building envelope and inside cannot be sustainable. Sustainability also starts with fullfilling the Basic Works Requirements. The European Construction Products Regulation (305/2011) defines 7 Basic Works Requirements. If for example the 1st Basic Work requirements - Mechanical resistance and stability – is not fulfilled, the building collapse or deformations hinder the functioning of the activities in the building, then all products used in the building construction and in the building interior, are no longer sustainable. If the building or part of the building for example catches fires because Basic Work requirement nr 2 – Safety in case of fire – is not fulfilled, all sustainability efforts for building and products become worthless.So: sustainability starts with the Basic Works Requirements; with a good functional and technical design and construction!

But once the functional and technical design is made , and realised, this has an impact on the environment, on the society and the economics.Sustainability is based on the solutions for meeting the functional and technical needs and measured in 3 dimensions: environmental performance, social performance and economical performance.The CEN TC350 standards allow measuring on these 3 dimensions of sustainability. The standards do not define what is sustainable and what not. They do not clasify or give ratings, they only quantify.
