Decision making on the indoor environment and building envelope of Canada's Library of Parliament.

A year-long monitoring program was undertaken at Canada's Library of Parliament to answer the following:

Selective ventilation in large enclosures.

A new method for providing ventilation in large enclosures, which utilizes the principle of 'selective withdrawal' of contaminants while ensuring energy-efficiency and allowing a better use of space, is presented in this study. The concept is based on dividing the enclosed space ventilation-wise into separate zones using a combination of horizontal partitions by stratification and vertical partitions by temporary walls. This gives a high degree of flexibility in the use of available space.

Economical energy efficient large scale office buildings.


Large office buildings, what are the dominant parameters for energy consumption?

The thermal behaviour of an office building is presented and discussed, as well as the results of a sensitivity study, which analyses the impact of architectural decisions and the effect of occupancy in terms of energy consumption (cooling and heating loads). This study was carried out using one floor of an office building, with large glazed facades, recently built in S. Paulo in Brazil, which was monitored for a short period (11 days)]. This building has been used as reference, for the sensitivity studies carried out for two climates, S. Paulo in Brazil and Lisbon in Portugal.

Natural cooling in Hispano-Moslem religious architecture: the case study of the Mosque of Cordoba.

The Mosque of Cordoba is the best example of the Islamic religious buildings that survived in Spain. Its typology corresponds to a mosque of a large scale with the common plan of the early Muslim art. This model became an architectural reference for the mosques of Western Islam. The paper presents the results of measurements undertaken to assess the environmental performance of this building.

Measurement and evaluation of the indoor thermal environment in a large domed stadium.

This paper describes the measurements and evaluation of the indoor thermal environments in a large domed stadium. This stadium was built mainly for professional baseball games, but it has a lot of other purposes. It will be used not only for many sport games but also for various entertainment events. To satisfy such purposes, various intelligent mechanical systems were equipped to control and create a suitable space and environment without consuming excessive energy.

Problems with descriptive energy efficiency standards (NZS4243:1996).

This paper presents a synopsis of the content of the New Zealand Standard for Energy Efficiency in Large Buildings. This new standard is purported to be 'descriptive'. The paper outlines the three permissible methods for demonstrating compliance with the Standard's requirements. Disadvantages of this approach are stated and an alternative proposal is suggested.
