Retrofit of a 1970s apartment building into energy plus, results of a prototype apartment

Abstract

Project ‘Inside Out’ aims to turn apartment buildings from the 1960s and 1970s into energy plus (InsideOut, 2021). In order to achieve this goal, a retrofit design is made, and tested by means of a pilot apartment. Results of this pilot showed that, with minor adjustments, the energy demand of the building would be smaller than modelled, while adequate levels of comfort are maintained. The projected energy output of the PV system is sufficient to exceed the energy demand of the building
