Buildings account for almost 40% of energy consumption in European countries and hence are responsible for a significant part of greenhouse gas emissions. Recent regulations and standards (Minergie, Minergie P, etc.) are strongly encouraging more sustainab ...
This paper describes the City Energy Analyst (CEA), a computational framework for the analysis and optimization of energy systems in neighborhoods and city districts. The framework allows analyzing the energy, carbon and financial benefits of multiple urba ...
The energy demand increases worldwide and due to the fact that fossil fuel is still dominating the energy mix, the corresponding CO2 emission becomes a more serious problem that threatens the global environment. The building sector is the largest energy co ...
The first step in order to comply with the European Union goals of Near to Zero Energy Buildings is to reduce the energy consumption in buildings. Most of the building consumption is related to the use of active systems to maintain the interior comfort. Pa ...
Evaluating the energy consumption of different design solutions during the design process is essential to reach energy targets. Conventionally, building energy performance is evaluated with energy simulations using a single input weather file (design or ty ...
Currently, energy efficiency in buildings is a primary objective of energy policy at regional, national and international levels. On a local scale, this trend has been detected also in Switzerland, where almost 40% of energy consumption has been assumed to ...
In the past decades the portion of the population living in urban areas has continuously increased. Due to the high building density, the microclimate in urban areas changed significantly compared to rural areas. The temperatures measured in urban areas ar ...

Veluxlab is the first Italian Nearly Zero Energy Building. It is placed in Bovisa Campus of Politecnico di Milano and it represents a study case of high energy efficiency building, integrating in the future scenario required by the European Directive 2010/ ...
Conventionally, building energy performance is evaluated through energy simulations using a single input weather file referring to present weather conditions. However, the analysis shown in this study demonstrates the high sensitivity of calculated energy ...
This study consisted in the development of a canopy model (CIM), which could be use as an interface between meso-scale models used to simulate urban climate and micro-scale models used to evaluate building energy use. The development is based on previously ...
