Improving common constructive solutions and substituting HVAC systems for more efficient ventilation systems leads to significant opportunities to decrease energy demand for heating and cooling and for improving occupant’s comfort. Passive House (PH) conce ...
Warm climates pose challenges to building energy consumption and pedestrian comfort. Knowledge of the wind flow around buildings can help address these issues through improving natural ventilation, energy use, and outdoor thermal comfort. Computational flu ...
In a time when governments are pursuing increasingly ambitious energy efficiency goals, building energy simulation at the urban scale, combined with the high availability of physical data, can help in performing this task. The purpose of this study is to d ...
Different climates may need different design strategies for optimal thermal performance of buildings: the relationship between different texture of the cities (their form and morphology), the energy demand of buildings and the outdoor microclimate are esse ...
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 city is a very complex system in which many parameters converge. The large number of these parameters greatly hinders not only an accurate analysis of all of them, but also the assessment of the phenomena that occur in the city and its impact on the en ...
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 Switzerland, according to Swiss Federal Office of Energy around 50% of primary energy consumption is attributable to buildings: 30% for heating, air-conditioning and hot water, 14% for electricity and around 6% for construction and maintenance. However, ...
The aim of this article is to study by numerical simulation with the TRNSYS-COMIS software, the thermo-aeraulic behavior of a traditional house with a horizontal opening in the central space of the house, and in the city of Kenadsa (southwestern Algeria, h ...
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 ...
