Photovoltaics and Architecture

Photovoltaics and Architecture

Photovoltaic systems (PVs) produce electricity directly from solar radiation and are becoming more widespread as their advantages become apparent. This new guide provides an overview of how PVs work and how they are incorporated in the design of buildings, giving designers a good idea of the variety and flexibility of PVs and of their design and aesthetic potential. Seven contemporary case studies illustrate the use and application of photovoltaic systems.

Packed Tower Design and Applications

Packed Tower Design and Applications :
Random and Structured Packings
Second Edition  

During the last 25 years, significant changes have taken place in both the design of tower packings and the application of packed columns. Increasingly, concerns have turned from capacity to energy efficiency and the environmental impact of processing operations. 

This new edition has been retitled and updated throughout to reflect these changes and the expanded uses for structured packages. It provides basic information on the operation mechanism of packed columns, as well as practical methods for designing such columns, proven methods that have been used over the last decade to design columns as large as 46 feet in diameter and for separations requiring as many as 128 theoretical stages. 

The procedures presented are based on the author's practical experience acquired over 40 years, and have in many cases been developed as a result of real-life modifications. The numerous and varied major applications of packed columns are reviewed, so that their advantages as compared to other mass transfer devices can be determined. 

Particular characteristics of a system that need to be considered to ensure successful column operation are discussed.

Energy Conservation in Buildings

Energy Conservation in Buildings :
 A Guide to Part L of the Building Regulations

The conservation of fuel and power in buildings is an important part of the UK government's strategy to reduce national energy conservation. The revision to Part L of the Building Regulations, which came into force on 1 April 2002, lays down detailed and extensive requirements for conserving energy in almost all buildings and it covers most potential causes of building energy consumption.

This guide explains these detailed requirements and shows how they apply to particular cases, with the use of numerous worked examples. It includes a chapter on air tightness and leakage testing, a topic with which many building professionals are unfamiliar.

Solar Architecture: Strategies, Visions, Concepts (In Detail)

Solar Architecture: 
Strategies, Visions, Concepts (In Detail)

In the very near future energy-efficient building will be the rule rather than the exception. 

Insulating glazing, multi-functional facades and organic solar cells are examples of important new developments in the field of solar thermal technology, photo-voltaics, heating and ventilation technology which are suitable for a wide range of uses from large-scale urban-planning projects to individual single family houses, and can make significant contributions to the conservation of natural resources in sustainable building.

 Carefully selected articles provide information on planning methods and techniques which will enable the user to assess and apply appropriate measures. 

The essays are complemented by a selection of built examples which demonstrate innovative solutions and the importance of an integrated planning process in realized projects, complete with full plans and large scale details.

Building Acoustics

Building Acoustics

Building or architectural acoustics is taken in this book to cover all aspects of sound and vibration in buildings. The book covers room acoustics but the main emphasis is on sound insulation and sound absorption and the basic aspects of noise and vibration problems connected to service equipment and external sources. 

Measuring techniques connected to these fields are also brought in. It is designed for advanced level engineering studies and is also valuable as a guide for practitioners and acoustic consultants who need to fulfil the demands of building regulations.

It gives emphasis to the acoustical performance of buildings as derived from the performance of the elements comprising various structures. Consequently, the physical aspects of sound transmission and absorption need to be understood, and the main focus is on the design of elements and structures to provide high sound insulation and high absorbing power. 

Examples are taken from all types of buildings. The book aims at giving an understanding of the physical principles involved and three chapters are therefore devoted to vibration phenomena and sound waves in fluids and solid media. 

Subjective aspects connected to sound and sound perception is sufficiently covered by other books; however, the chapter on room acoustics includes descriptions of measures that quantify the "acoustic quality" of rooms for speech and music.

Architectural Acoustics: Blending Sound Sources, Sound Fields, and Listeners

Architectural Acoustics:
 Blending Sound Sources, Sound Fields, and Listeners
1998 | 224 pages | PDF | 19,3 MB

Proceeding from basic theory to design studies of concert and multiple purpose halls, the author introduces a remarkable seat selection system for the analysis of new and existing halls, and proposes a diagnostic system for testing the physical properties and calculating the psychological attributes at any seat after a hall is built. 

The book also presents a theory of subjective preferences, based on a model of the auditory cognitive system in the brain. 

Readers can thus follow the temporal and spatial values that may be associated with the left and right cerebral hemispheres in listening to music and speech, respectively, in a room. 

From the results of calculating subjective preference at each seat, for example, architects, musicians, and acoustical engineers concerned with the design and use of concert and multi-use halls may determine the best location to perform a certain type of music on the stage, as well as the best seats from which to listen.
