【 摘 要 】

Public spaces play an important role in the social life and they are considered as the mirror and the reflection of the society. The uncomfortable microclimatic condition such as the air temperature, wind speed, solar radiation, etc. may encourage the pedestrian to avoid using these areas which effect directly the integration of residences and promote their segregation. In particular, the wind is considered as the parameter that influences the pedestrian comfort the most. However, it is heavily present in the design stage of urban and architectural projects at some places around the world, due to the complexity of the interaction with the urban fabric that create aerodynamic phenomena in the immediate environment of building and public space. Our subject of research focus on the Sun Valley living area inside the Laser Valley Land of Lights, which is one of the biggest projects in Romania that aim to attract high tech industry around the world's most powerful laser, Extreme Light Infrastructure Nuclear Physics ELI NP Project. Sun Valley was the result of an architecture international competition with the objective to provide an open research ecosystem based on sustainable development. Through this paper, we aim to investigate the wind environment in the design stage of the project. Mainly, we focus on the wind effects that are taking place in the large open space inside the campus on pedestrian comfort and safety, in order to provide comfortable area that promote the social life between residences. In this context, we describe the set-up of our research on the pedestrian comfort in the public space from the wind perspective, where Wind Tunnel measurement study on the pedestrian level (1.5 m to 2 m height from the ground) was carried out for 8 different wind directions in the TASL1-M Boundary Layer Wind Tunnel at the Aerodynamics and Wind Engineering Laboratory "Constantin Iamandi" (LAIV) in the Technical University of Civil Engineering Bucharest (UTCB). Furthermore, the preliminary result of the experiment performed in the TASL1-M Boundary Layer Wind Tunnel are described.
