Existing historic buildings are often still fully functional, but they require a relatively high amount of energy to operate. Without interventions, they contribute to the 40% share of total greenhouse gas emissions related to the built environment. This renovation project examined different interventions to the thermal envelope of the Sodafabriek in Schiedam, an 18th century industrial building, aimed at lowering energy demand. Building simulations showed that improving the thermal quality of the building envelope achieves only partial energy savings. We concluded that more holistic approaches which deal with all aspects of energy generation, supply and distribution are required in order to achieve highly energy-efficient buildings. Highly energy-efficient buildings are the prerequisite to bring the built environment to net zero carbon emissions.
