Expert says in-depth analysis is key to energy retrofits

Ben Welter - Wednesday, January 28, 2015

Matteo D'AntoniMatteo D’Antoni, a senior researcher at the European Academy of Bozen/Bolzano in Italy, talked with about installing energy-saving technologies in existing buildings. He lists three important planning steps:

  1. Evaluate the building's existing energy consumption.
  2. Evaluate the integration of passive technologies, such as phase change material.
  3. 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."
