A strategic approach and holistic planning are important elements of sustainable building development. They can be supported by current technology, which, for example, can visualise and benchmark a building’s actual environmental performance. However, management of environmental building performance (EBP) through IT systems has experienced difficulties in gaining a solid base, partly due to a lack of core data on buildings, but also to erroneous consumption data and a lack of overview of consumption patterns.
This presentation shows how certain IT systems in Real Estate Management (REM) can promote sustainability by reducing REM’s negative environmental impacts. This is primarily achieved through the successful implementation of IT systems that can process large amounts of different data on buildings and their performance. However, to succeed with the implementation, IT systems must support the business processes that an organisation requires regarding REM.
Nowadays, IT systems such as Integrated Workplace Management System (IWMS) and Energy Management System (EMS) can collect, combine, analyse and present core data and dynamic consumption data. This opens up new possibilities to base EBP on actual operating data and provides opportunities for deeper performance analysis and faster failure detections.
The research focus has been on four different organisations that use various IT systems to monitor and benchmark EBP. The empirical results from the main case study show that IWMS implementations are complex and require many resources, though they can add value, particularly to large-scale REM organisations. In addition, the three remaining case studies show that the EMS is particularly beneficial for collecting and processing dynamic data on electricity, heating and water consumption. Moreover, the research shows that EMS can be further supported by BMS (Building Management System), which focuses on the management of technical installations, and that IT systems as Microsoft Excel also can be used to report and benchmark EBP.
Cross-case analysis shows that the focus in organisations is mainly on energy and water consumption and emissions, while environmental categories regarding space management, building materials and recycling are either not supported in IT systems or are not demanded by the organisations studied. Further analysis of energy data shows that EBP not only depends on energy consumption but also on the time of consumption and the location of the building (region).
Finally, based on empirical observations from the case studies, a stepwise model for improving EPB through IT systems in REM is presented.
