This dissertation was written as a part of the MSc in Energy Systems and supervised
by Dr. Dimitrios Anastaselos. The main objective of the thesis is to investigate the impact
of different ventilation strategies that can be implemented in new and existing
buildings in hot climates and specifically under climatic conditions prevailing in the
In the context of the study, a reference building model has been developed and its
energy performance has been evaluated. The model incorporates features proposed by
design frameworks for net zero energy buildings. Α base case ventilation scenario has
been defined as well.
Different variants of the base case ventilation scenario have been simulated and the
impact of each one on the cooling energy demand, overall energy consumption and indoor
temperature was evaluated. The interaction of ventilation with buildings’ construction
parameters (thermal mass, heat transfer coefficients) has been also assessed.
The requirements for energy generation from RES induced by each scenario have
been identified and the feasibility of the net zero energy balance was tested.
