Matteo D’Antoni, a senior researcher at the European Academy of Bozen/Bolzano in Italy, talked with youris.com about installing energy-saving technologies in existing buildings. He lists three important planning steps:
- Evaluate the building's existing energy consumption.
- Evaluate the integration of passive technologies, such as phase change material.
- Evaluate the integration of active technologies, such as solar energy.
"It is a complex approach," he explained. "One the one hand, we have to calculate how much primary energy can we save; on the other, how much it costs. Technologies have to be easy to install and maintain and [incur] a limited investment cost. If they are expensive, we have to understand whether it makes sense to install them. And this analysis has to take into account the energy concept of a specific building replaced in its own environmental context."
