Abstract This study discusses the interplays between urban form and energy performance using a case study in Singapore. We investigate educational urban quarters in the tropical climate of Singapore using simulation-based parametric geometric modelling. Three input variables of urban form were examined: street network orientation, street canyon width, and building depth. In total, 280 scenarios were generated using a quasi-Monte Carlo Saltelli sampler and Grasshopper. For each scenario, the City Energy Analyst, an open-source urban building energy simulation program, calculated solar energy penetration. To assess the variables’ importance, we applied Sobol’ sensitivity analysis. Results suggest that the street width and building depth were the most influential parameters.

This paper looks at the City of Melbourne's new office development CH2 as a case study of world class energy performance. In particular, the integrated design of conventionally independent systems has led to the potential to deliver significant savings to the Council and to deliver better environmental conditions to building occupants that in turn may contribute to satisfaction, well-being and productivity. It is concluded that this project has the potential to be an iconic example of effective implementation of ESD (environmental sustainable design) principles and therefore act as a demonstration project to others. Energy efficiency of more than 50% of current benchmarks for Melbourne is effected. Energy harvesting is defined as arising from squander, waste and nature, which is a new concept introduced in this paper to better describe the design decision process.

A reliability analysis framework is used to evaluate the risk of limited sight distance for permitted left-turn movements due to the presence of opposing left-turn vehicles. Two signalized intersection approaches in the city of Surrey were used as case studies for the framework. Geometric and traffic video data was collected and analyzed using a computer vision tool to extract the input variables probability distributions. The data was used in the reliability analysis where first-order and Importance Sampling methods were performed. The analysis showed that the probability of non-compliance was considerable at one approach due to its large left-turn lane offset. The analysis also showed that the probability of non-compliance increased substantially when the obstacle vehicle was a bus rather than a passenger car. Moreover, the time gap had a higher impact on the probability of non-compliance compared to speed. Strategies were suggested to overcome the high probability of non-compliance.

The model of double monetary improvement contains the lowest wages (between difference foundations) responsible for the continuous dualism. We use 2 years of micro data from a large number of workers in Pakistan to test whether legally lowest wages have different effects on formal compensation, as opposed to the occasionally different segment. We find that the evidence from Pakistan rejects the assumptions of these models: raising the minimum wage not only extends the compensation in the city format part (big urban effort), which are enclosed through the least wages rule, nonetheless also increases the salaries of altogether other specialists, z Lowest legal allowance, which is generally considered to be an occasional split and is not regularly enforced (eg, small municipal companies, large provincial companies and small country companies). Our finding also suggest that the lowest statutory minimum wages increase wages for specialists in these “random” departments more than in the urban form, and therefore may lose the normal pay gap amid these segments and city additional part, which is considered non- binding nonetheless not governed b the Least Wage Act: the freelance (in together city and provincial regions). Least salaried may therefore lead to a symmetry amid official & casual workers, who referred to as self-employed and paid labors. In any case, we discovery no indication that self-earned income falls by the lowest pay.

The accelerated urban growth of the last decades in Europe has caused, especially in the Spanish Mediterranean coast, a paradigm shift in much cities, moving from a mostly compact urban form to a more diffuse one. The concept of city has changed so much that even in a lot of dispersed municipalities, it becomes difficult to define its limits. This change implies not only ecological and economic impacts, but also, social effects. Urban sprawl makes difficult social interaction and reduces the community feeling, and therefore, social cohesion and identity. This produces also changes in the relations of citizens between them and with the city council. The research propounds a discussion about the challenges that the urban sprawl causes for the application of participative models in the decision making, understanding them as basic criterion of good government. We analyze a case study to extract the complexity of articulating processes of citizen participation in territory with high dispersion based on a project carried out in the municipality of La Pobla de Vallbona (Valencia) on participatory budgets. It analyzes the results of the process carried out in relation to the urban model, the morphology of their urban pieces and spatial structure, and the demographic and social characteristics of the municipality. The question is identifying the problematic for the articulation of participative processes in territories with this idiosyncrasy. Finally, the article suggests a series of strategic lines as starting points to achieve participatory processes in the city characterized by urban sprawl.

Abstract This document is a case study of hemp-based materials integrated into the building envelope for African and North American’s applications. The objective is to evaluate the energy performance of hemp concrete for construction in Montreal, Canada, where heating predominates and in Dori, Burkina Faso, where air conditioning predominates. The effect of thermal and hygrothermal comfort of hemp concrete, glass wool, cement block and compressed earth brick walls were simulated to quantify the benefits on overheating during the hottest months for the city of Dori and the risk of mould growth in the walls of the building in winter for the city of Montreal.
