Data
• Total building area approx . 11000 m2 of which 7,300 m2;
• Annual consumption not more than 84 kWh/m2 must
meet energy class A.
• The building is connected to district heating plants ,
power grids and also has its own production of electricity
in a solar system.
Solar System
• 203 m2 on the south and west facades, 27.2 kWp, 9
strings;
• The estimated annual production of approx. 18,000 kWh;
• Actual production in 2013 approx . 15,000 kWh. 15%
higher than simulated.

Methodology
Reconciling Adaptation, Mitigation and Sustainable Development for Cities
• Analysis conducted using ENVImet.
• Meteorological parameters, albedo of the surface and solid angle proportion.
• Outputs Predicted Mean Vote (PMV), Physiological Equivalent Temperature (PET) to evaluate the thermal stress affecting the body;
• Building geometry/orientation, vegetation elements, urban parks, and street canyons;
• Analysis of urban thermal comfort and impact assessment of climate change scenarios in urban areas.
