In Six Degrees: Our Future on a Hotter Planet, Mark Lynas describes possible world scenarios as global temperatures rise. The central region of Brazil, where Brasília is located, will suffer major changes in its microclimate.Brasília's built environment has already provided a comfortable indoor and outdoor condition through planned urban design and vegetation.

The study is placed within the context of local building regulations in India. Building regulations, for fenestration in general and window openings in particular, are, to a large extent, ambiguous in nature. In the context of India, observations show that the regulations specify window size for the sole purpose of ventilation whereas windows are major roleplayers in the thermal and daylighting performance of buildings.

This paper presents a model-based supervisory control strategy for online control of building central cooling water systems to enhance their energy efficiency. Simplified chiller and cooling tower models are developed and used to predict the system energy performance, environment quality as well as the system response to the changes of control settings. A novel and simple optimization technique, named as PMES method, is developed and used to seek the optimal control settings under the given working conditions.

This paper presents a new methodology for largescale commercial buildings energy consumption data analysis. This methodology relies on a unified energy consumption classification structure and on a set of index models and estimating models. All these elements have been combined into a data model that is presented in this article. This new methodology has been applied successfully to 4 office buildings, two of them being Chinese and two of them being French.

This paper aims to analyze an office building energy performance at Rio de Janeiro. Electrical power consumption profile of a building, resulting from a simulation using building energy-use simulation software, is obtained during a typical year and is shown on an hourly basis and pursuant to final uses. Thus, power consumption figures are obtained through the following final uses: lighting, office equipments, air conditioning and others.

There is an increasing demand for energy efficient and environment-friendly buildings with a high thermal comfort. On the other hand, the Kyoto protocol binds the developed countries to reduce the emission of greenhouse gases at least by 5% by 2008-2012.

The paper discusses the concept of an adaptive thermal comfort design methodology and its impact on the selection, design and performance of climate control systems for large public spaces with transient occupancy in hot and humid climates. It outlines the design methodology which is based on providing localised comfort conditions to zones within a building based on its occupancy patterns, activity of occupants and acceptable thermal comfort criteria. The methodology focuses on quantifying the collective impact of space operating parameters on the thermal comfort of its occupants.
