Beyond building envelope: about internal and external boundary conditions
Global climate change + urban climate
Indicator: Urban Heat Island Index
Mean hourly UHI distribution (rd‐s/7)
Beyond UHI‐Index:
The variance of the urban micro‐climate
A tale of two streets
The street without trees has:
Cooling load
How to predict the effectiveness of mitigation?
The potential and limits of urban scale models and the importance of model calibration
What variables influence urban climate variance?
Sky View Factor
What variables influence urban climate variance?
Aspect Ratio of the Urban Canyon
What variables influence urban climate variance?
Building Compactness
CTI correlation with the variables of the U2O - Vienna, reference summer day
CTI correlation with the variables of the U2O - Vienna, reference summer day
CTI correlation with the variables of the U2O - Vienna, reference summer day
Aspects of people's presence and behavior in buildings
Two common fallacies
Case study
Results
Window operation models
Window operation predictions - Validation calendar year
Implications for annual heating demand prediction
When use what model?
Predicted heating loads for 7 retrofit projects
Predicted heating loads for 7 retrofit projects
versus monitored values (2009/2010)
Predictions corrected for ventilation rates
(from about 0.2 h‐1 to about 0.9 h‐1)
Concluding remarks
