Numerical Analysis – Model Validation

• Validated building model of Design Builder used for parametric thermal analysis of alternative operation scenarios

• 3D CFD flow solver of Design Builder was employed (FVM). Equation set comprises of the 3 velocity component momentum equations, the Navier-Stokes equations, the energy equation using the k-ε turbulence model

Numerical Analysis – Night Ventilation - PPD

• With the exploitation of natural ventilation an average PPD index of 16% is achieved while significantly higher percentage of dissatisfaction was retrieved with continuous operation of the HVAC system during night hours (i.e. 35%). This is quite interesting, underlining the significance of natural ventilation.

Numerical Analysis – Night Ventilation – Air Velocity

• Air Velocity ranging between 0.06 – 0.12 m/s (within comfort levels)

Energy consumption

• Total energy consumption from 23.12.2014 until 24.11.2015 was 3443 kwh

• Primary energy 63 kwh/m2/a

• Cooling and heating energy consumption was 380 kwh

• 7 kwh/m2/a primary energy for cooling and heating ( calculated 15kwh/m2/a )

• 3 KW PV Panel in Cyprus can produce around 5000 kwh/a

Conclusion

- Net positive energy buildings in Cyprus are possible

- Needs special attentions for shading

- Small cooling load – difficult to design the cooling system
