Towards Net-Zero Neighborhoods in Greece
Abstract
By applying energy efficient standards in multi-apartment buildings, the installation of PV and solar thermal collectors in the available roof space is investigated aiming to map a guide for net-zero neighborhoods. A real building is considered varying the number of stories in various Greek climates. Very good standards such as EnerPHit are applied to investigate the potential of covering the electricity loads with PV. The results show that in a neighborhood with 9 buildings from 3 to 5 story buildings, the PV yield could cover 80% of the total required electricity of the year.
