Discusses the measurement and control of air moving inside buildings and between the inside and outside in 17 papers and discussions from a symposium in Dallas/Fort Worth in October 1993. After an overview of the subject, covers air movement, ventilation, and indoor air quality; window air leakage;
Ensuring optimum ventilation performance is a vital part of building design. Prepared by recognized experts from Europe and the US, and published in association with the International Energy Agency's Air Infiltration and Ventilation Centre (AIVC), this authoritative work provides organized, classified and evaluated information on advances in the key areas of building ventilation, relevant to all building types. Complexities in airflow behaviour, climatic influences, occupancy patterns and pollutant emission characteristics make selecting the most appropriate ventilation strategy especially difficult. Recognizing such complexities, the editors bring together expertise on each key issue. From components to computer tools, this book offers detailed coverage on design, analysis and performance, and is an important and comprehensive publication in this field. Building Ventilation will be an invaluable reference for professionals in the building services industry, architects, researchers (including postgraduate students) studying building service engineering and HVAC, and anyone with a role in energy-efficient building design.
Although there have been numerous innovative developments for building systems and technologies in response to the current declining environmental conditions, there is still a gap within practice and research between conducting and evaluating data from building performance studies and design priorities. Currently, there are no standardized methods/systems to incorporate such quantitative data into the architectural design process. The main thesis enquiry is to investigate a methodology through which a parametric analysis of energy performance and occupant thermal and visual comfort, can become a driver for design decisions of high-performance building envelopes for office buildings. This study is approached as an interface analyzing specific variables according to thermal, lighting, and airflow performance. This interface also includes a comparative analysis component that attempts to create an evaluation criteria and a graphic language to interpret performance data to architects and designers. This study of the building envelope begins to frame a methodology in which specific aspects of performance data can be calculated, understood, and utilized to directly inform design decisions. It also suggests ways in which performance data can be compared and evaluated against various standards for occupant comfort, as an integral part of the design process. Ultimately, this research seeks to explore and visualize architecture not as static objects, but as dynamic exchanges of energy flow that respond to its climatic context and occupant needs.
'Several high quality scientific journals are published in the area of building energy and indoor/outdoor environment; however, one has been missing. Advances in Building Energy Research fills the gap. I recommend ABER to all technical libraries, research institutes and universities. It should also be used by construction companies and those manufacturing building materials and building products.' Professor Olli Seppi? nen, President of REHVA (Federation of Heating and Air-conditioning Associations) 'Advances in Building Energy Research is a unique index. It will be an inexhaustible resource for energy related sciences and a continuous inspiration for architects around the world.' N. Fintikakis, Architect and Director of UIA-ARES WP (Architecture and Renewable Energy Sources) Advances in Building Energy Research (ABER) offers state-of-the-art information on the environmental science and performance of buildings, linking new technologies and methodologies with the latest research on systems, simulations and standards.As stringently reviewed as a journal but with the breadth of a book, this annual volume brings together invited contributions from the foremost international experts on energy efficiency and environmental quality of buildings. Spanning a broad range of technical subjects, this is a 'must have' reference on global developments in the field, suitable for architects and building engineers, environmental engineers, industry professionals, students, teachers and researchers in building science, technical libraries and laboratories.
Annotation All of the presentations and the papers in this publication address ways to improve the performance of exterior building walls, or ways to identify, understand, and avoid the factors leading to failures in the future.
Office building envelopes are generally successful in meeting a range of structural, aesthetic and thermal requirements. However, poor thermal envelope performance will occur when there are discontinuities in the envelope insulation and air barrier systems, such as thermal bridges and air leakage sites. These discontinuities result from designs that do not adequately account for heat, air and moisture transmission, with many thermal defects being associated with inappropriate or inadequate detailing of the connections of envelope components. Despite the existence of these thermal envelope performance problems, information is available to design and construct envelopes that do perform well. In order to close the gap between available knowledge and current practice, the Public Buildings Service of the General Services Administration has entered into an interagency agreement with the Center for Building Technology of the National Institute of Standards and Technology to develop thermal envelope design guidelines for federal office buildings. The goal of this project is to transfer the knowledge on thermal envelope design and performance from the building research, design and construction communities into a form that will be used by building design professionals. This report describes the NIST/GSA envelope design guidelines development at the end of the first year of effort on the project. The effort to this point has consisted of a literature review of research results and technical information on thermal envelope performance and design, an assessment of existing design guidelines as they relate to the thermal envelope, and the development of a format and outline for the design guidelines.
