Building renovation: Optimal use of ESG data

With Quantrefy, the collection effort for GRESB and ECORE had to be significantly reduced.

Frankfurt am Main. – How can buildings be modernized based on ESG data and how can digital tools support the process? While new buildings are increasingly being developed with sustainability in mind, this factor hardly plays a role in light of the huge stock of existing buildings, says provider Quantrefy. The key to achieving the climate goals and for a sustainable building mass lies in the renovation of the existing properties.

The basis for a future-proof renovation and thus climate-friendly optimization of existing properties is therefore sustainable portfolio management and development. Here, ESG data can be the key to a successful restructuring. But since data collection and use is a very time-consuming process that requires clear structures, digital solutions can be the decisive factor for success and bring more efficiency into the process. ESG implementation platform Quantrefy is intended to help put data collected from an existing property into a meaningful relationship and use it effectively.

The collection of property-level data and its use is currently the biggest challenge in ESG-compliant portfolio management. However, the collection of data is not the biggest obstacle. The main difficulty is that data can only be used purposefully if they can be compared with relevant target and reference values. Optimization successes could therefore only be measured if the actual status and target status were clearly recorded. It is therefore absolutely necessary to also centrally register current data that is available from a building. According to Quantrefy, it is also essential to define meaningful key performance indicators (KPIs) for the ESG performance of your own properties and to adapt the modernization roadmap accordingly. There is no need to reinvent the wheel for this: There are already different evaluation models, such as CRREM and GRESB, with different focus points that can be used as a basis for orientation – specially defined focus points also help to reach the goal.

But simply collecting data is not enough: although they form the basis for building renovation, they are not effective in themselves. What is important is what is done with the data, i.e. how it is interpreted. To do this, collection and analysis must be systematized sensibly – only in this way can they lead to clear impulses for action. These impulses form the basis for the actual implementation of modernization measures. For this, it is important that the various data are interconnected and positioned in relation to each other.

According to the company, too many isolated systems are currently used for this: if different types of building data are evaluated largely independently of each other, it is time-consuming and not particularly resource-efficient. It also prevents a holistic view of the respective building and thus a complete consideration of the optimization effects. In addition, there were many ways to find information or use ESG data in relation to the renovation of buildings. However, the use of many different digital tools also increases the risk of no longer having an overview of the process, which in turn affects time and costs, Quantrey is sure. There is therefore a need for a central interface solution where data from different sources flow together and are evaluated holistically.

The climate-neutral construction sector is finished – but an effective building renovation can only work if you take all ESG criteria into account from the start and bring structure to the process, says the provider. After all, successful, sustainable renovation of buildings means not only making real estate more environmentally friendly, but also using time, financial and human resources wisely.

This is where ESG implementation platforms like Quantrefy come in. They can initially support the evaluation of the current status and provide a real-time overview of whether the predefined key figures have been met. As an additional advantage, digital tools based on the data base can create orientation and prioritize the various modernization initiatives through concrete recommendations for action. The project manager is shown which initiative is best to start with and what effect this has. Structure is thus introduced into the process, and a well-founded restructuring plan can be drawn up.
