- Four urban public spaces, representing various designs and microclimates, were investigated in Gothenburg, Sweden, in order to estimate how weather and microclimate affect people in urban outdoor environments. The research strategy was both multidisciplinary and interdisciplinary and included scientists from three disciplines: architecture, climatology and psychology. The project is based on common case studies carried out during four seasons, including measurements of meteorological variables, interviews and observations of human activity at each place. Multiple regression analysis of meteorological and behavioural data showed that air temperature, wind speed and clearness index (cloud cover) have a significant influence on people's assessments of the weather, place perceptions and place-related attendance. The results support the arguments in favour of employing climate sensitive planning in future urban design and planning projects, as the physical component of a place can be designed to influence the site-specific microclimate and consequently people's place-related attendance, perceptions and emotions.

- We report on the effect of the overall shape of a city on the flow within the street network. We start with a solid round block, aspect ratio, diameter/ height = 6. The block is subdivided into smaller blocks and step by step an increasing number of streets are introduced. In the wind tunnel visualization with helium filled soap bubbled was carried out for obtaining qualitative information about the flow pattern. The pressure distribution on the ground within the street network was recorded in 400 points. CFD predictions provided the overall flow balance; flow entering through the street portals, leaving through the exit street portals and the updraft.

Numerical and experimental studies of wind environment in an urban morphology

- The purpose of the paper is to examine the relation between urban morphology (three-dimensional structure) and windiness. We regard a city as a porous obstacle, which is open at the top. We consider the interaction between the atmospheric boundary layer and a city to be both a function of the overall shape (silhouette or skyline) and the internal resistance to the flow caused by the friction when the wind flows over the urban surfaces. We regard the street pattern as an interconnected flow network with the crossings as nodes. Flow, along the streets is generated by pressure differences. We here use a highly idealized city model consisting of a circular block divided into two or four equally large sectors. Two types of cases are studied, the first with only one street through the city model with different angles between the street and the oncoming wind. The second case also contains a perpendicularly crossing street (through the center). Both wind tunnel experiments and numerical flow computations (computational fluid dynamics, CFD) are used and compared. The general agreement between the two is good and the CFD method offers new possibilities for quantifying the urban wind environment.

Framework for Detailed Comparison of Building Environmental Assessment Tools
- 2013

- Understanding how Building Environmental Assessments Tools (BEATs) measure and define “environmental” building is of great interest to many stakeholders, but it is difficult to understand how BEATs relate to each other, as well as to make detailed and systematic tool comparisons. A framework for comparing BEATs is presented in the following which facilitates an understanding and comparison of similarities and differences in terms of structure, content, aggregation, and scope. The framework was tested by comparing three distinctly different assessment tools; LEED-NC v3, Code for Sustainable Homes (CSH), and EcoEffect. Illustrations of the hierarchical structure of the tools gave a clear overview of their structural differences. When using the framework, the analysis showed that all three tools treat issues related to the main assessment categories: Energy and Pollution, Indoor Environment, and Materials and Waste. However, the environmental issues addressed, and the parameters defining the object of study, differ and, subsequently, so do rating, results, categories, issues, input data, aggregation methodology, and weighting. This means that BEATs measure “environmental” building differently and push “environmental” design in different directions. Therefore, tool comparisons are important, and the framework can be used to make these comparisons in a more detailed and systematic way.

Les outils de mesure de la durabilité des bâtiments : comparaison transnationale

- Les outils d'évaluation environnementale des bâtiments se développent rapidement dans de nombreux pays. Tous prétendent mesurer la qualité environnementale ou la durabilité des bâtiments, et donnent un maximum de points à ce qui est durable d'une manière ou d'une autre. Mais pour l'instant il n'y a pas de consensus sur le sens des mots « vert » ou « durables » en termes de critères et d'indicateurs. Que cherchent à mesurer les indicateurs existant? Trois outils d'évaluation ont été retenus, l'américain LEED-NC, le britannique Code for Sustainable Homes (CSH) et le suédois EcoEffect. Ils ont trois champs d'évaluation principale en commun : l'énergie, l'environnement intérieur, les matériaux et les déchets. En revanche les contenus sont différents. Ces outils ont été comparés quant à leur but, leur contenu, et leur manière d'agréger les items. Ils ont été testés sur un immeuble neuf de plusieurs étages. Les résultats de leur application à cet immeuble divergent, ce qui pose la question de la définition d'outils d'évaluation réellement pertinents.
