Noise Control and Speech Privacy Guidelines for Office Building Design

Noise control is required to provide an indoor environment free from the stress of unwanted noise and to provide a measure of speech privacy. There is a need for the development of guidelines to be used by building designers to ensure that user comfort is taken into consideration. The focus of this paper is on the development of guidelines as advice to designers to facilitate systems replacement in new buildings and the introduction of new systems in the future. Some aspects of noise control and speech privacy in various locations in office buildings have been addressed. Responses from 92 design professionals (architects and engineers) in nine countries to a questionnaire on noise control and speech privacy in office buildings have been summarized in the form of guidelines for use by building designers.

Vibration Serviceability of a Building Floor Structure. II: Vibration Evaluation and Assessment

People are generally very sensitive to unexpected vibrations. Very small levels of building floor movements due to activities such as walking can become annoying to occupants. Accurate prediction, evaluation, and assessment of vibrations can greatly assist engineers and architects to design cost-effective building structures without such problems. In an attempt to clarify some of the issues related to this common serviceability problem, this paper presents a study of the various parameters used for the evaluation and assessment of building vibrations. Provisions of several current standards and design guides commonly used in North America and U.K. to evaluate and assess building vibrations as related to human perception and comfort are reviewed. These provisions are then applied using the vibrations measured during a number of walking tests conducted on a large cantilevered office building floor. Based on the results of this study, it is concluded that the vibration dose value (VDV) recommended by some standards and design guides provides a consistent and reasonable method of evaluation of building floor vibrations. In addition, new relationships between VDV, peak frequency-weighted acceleration, and crest factor are established to estimate the VDV.     

The use of chemotherapy resistance in cancer treatment

It is not inconceivable that everything except the basic structure of an office building could be prefabricated in the near future. Quality and schedule are nearly always improved with prefabrication due to the simple change from an uncontrolled work environment to a controlled one. One Ludgate Place, is a 23,600 m2, ￡30,000,000 speculative commercial development in central London. This high quality office building has an exposed structural steel frame, within which are fitted prefabricated cladding panels. This paper combines the results from two research programs. The first in the area of prefabrication and the second in the management of high quality cladding construction. The writers describe the Ludgate Place project, incorporating the cladding design, testing, assembly, and installation. Factors that influenced the decision to use prefabrication are presented and evaluated, namely, cost; time; quality; past experience; design; weather joints; performance tests; site logistics; and safety. Construction interfaces and tolerances, particularly between cladding and structure, are discussed, and the future of prefabricated cladding is considered.

Expert System for Environmental Quality Evaluation

This paper presents the development of an expert system to evaluate the effects on environmental quality of proposed modifications to an office building following a postoccupancy evaluation. The model presented in this paper has been designated Expert System for Environmental Quality Evaluation (ESEQE). The ESEQE model consists of 200 rules covering 65 performance criteria of environmental quality. These performance criteria cover lighting comfort, acoustic comfort, thermal comfort, and indoor air quality. The performance criteria and the method of evaluation were extracted from a series of interviews with experts in the field of environmental quality in the built environment. The structure and development cycles of the ESEQE model are described. A demonstration of using ESEQE to evaluate the environmental quality in office buildings is presented. The potential benefits of using ESEQE during the design stages are also discussed.

Benchmark Problem for Response Control of Wind-Excited Tall Buildings

This paper presents an overview and problem definition of a benchmark problem for the response control of wind-excited tall buildings. The building considered is a 76-story 306 m concrete office tower proposed for the city of Melbourne, Australia. The building is slender with a height to width ratio of 7.3; hence, it is wind sensitive. Wind tunnel tests for such a 76-story building model have been conducted at the University of Sydney and the results of across-wind data are used in the present benchmark problem. Either active, semiactive, or passive control systems can be installed in the building to reduce the wind response, although only an active control sample problem has been worked out to illustrate the control design. In the case of active control systems, either an active tuned mass damper or an active mass driver can be installed on the top floor. In the case of passive or semiactive systems, such as viscous dampers, viscoelastic dampers, electrorheological, or magnetorheological dampers, etc., control devices can be installed in selected story units. Control constraints and evaluation criteria are presented for the design problem. A simulation program based on the linear quadratic Gaussian technique has been developed and made available for the comparison of the performance of various control strategies.
