Information Does a Building Passport Contain

A building passport is a digital document and data-set hosting all information relating to a real estate asset from its design through to its demolition stage. It is not a new concept, in fact, it builds on existing tools and practices (like BIM and a growing number of BREEAM and other accreditations), but is framed as a tool for the circular economy, bringing together all stakeholders and processes to support better decision-making and risk mitigation.

It is a kind of ‘nutritional label’ for a real estate asset, providing a clear picture of the building’s ‘ingredients’: what materials are used, where they came from, who supplied them, how they were installed, their condition at demolition or end-of-life, and their market price at the moment. The goal is to create a transparent understanding of the building and its assets in order to make them more valuable.

Ideally, a building passport is created during construction and kept up-to-date through a variety of methods (plan analysis, digital 3D scanning etc.). This will enable building and component information to be seamlessly shared throughout a building’s life-cycle, supporting both improved maintenance, and more efficient and sustainable material sourcing.

A key challenge is to ensure that the building information remains accurate. To achieve this, it is essential that the passport is a secure and trustworthy database. This will require a high level of data quality, as well as clear sharing and privacy guidelines for the information stored within it. It will also require the fourth owners of buildings to keep the passport up to date, even in case they do not own it for the full length of its lifespan.

The other big challenge is to encourage the use of healthy, sustainable and circular materials in the first place. This is why building passports provide strong incentives for both suppliers to produce and developers / managers / renovators to choose the best building products and materials. They also form part of a larger movement to develop circular business models for the whole building sector.

Incorporating building passports into the construction process is a good starting point, but it is important to focus on more far-reaching change. For example, legislation should be put in place to promote more sustainable building and to enable a move towards the provision of services instead of ownership of real estate assets. The creation of a more circular economy requires a fundamental shift in the way we think about building and real estate.

A wide range of stakeholders will need to be engaged in the implementation of a building passport, including regulators, insurers, banks, contractors, designers and manufacturers, certification bodies and intergovernmental institutions. This will be possible only if the different parties share a common vision and work together to achieve it. The DGNB has therefore set up a multi-stakeholder working group to help build this momentum. This will support the creation of practical recommendations and real-life examples for a more holistic approach to whole life data capture and management in construction and property.
