Buildings must become more energy efficient and will need to be significantly more sustainable in the future. But what exactly does sustainability mean in the context of buildings? This general concept includes many different aspects, such as:
- Use of uncontaminated, renewable materials, including raw materials
- Energy efficiency, i.e. low energy consumption
- Recycling options – social/health issues (e.g., ergonomic work posture)
Therefore, tying a building’s sustainability to just one aspect is short-sighted. “Sustainable construction/sustainable buildings always require a holistic approach,” says Ann-Christin Rachuba, Vice President Business Unit Interconnection Building at WAGO. Therefore, sustainability needs to be considered in the planning phase already, and every phase of the life cycle requires forward-looking planning. “Thanks to digitalization, this already works very well,” says Rachuba. “Building Information Modeling (BIM) allows us to build a model from the outset, which can then be gradually supplemented and enriched across all building systems. This approach not only stores information; it also makes it easier to access. That in turn makes it easier to determine the input information on energy flows necessary for life cycle assessments.”
