Fisette4 ABSTRACT This study examines the differences between two environmental assessment methods for the K-12 education sector: the United States Green Building Council’s (USGBC) LEED Schools Version 3.0 and the British Research Estab- lishment’s (BRE) BREEAM Education issue 2.0. Credit requirements are compared side-by-side and against recom- mendations from researchers in areas such as acoustics, lighting and indoor environment quality. Strengths in the two schemes and areas for improvement are highlighted, with acknowledgement that each scheme offers components and techniques from which the other could benefit.

  • Design Checks for Electrical Services
    A BSRIA Guide www.bsria.co.uk Design Checks for Electrical Services A quality control framework for electrical engineers By Kevin Pennycook Supported by BG 3/2006 Design considerations Design issues Calculations Systems and equipment PREFACE Donald Leeper OBE The publication of Design Checks for Electrical Services is a welcome addition to the well received and highly acclaimed Design Checks for HVAC, published in 2002. The design guidance sheets provide information on design inputs, outputs and practical watch points for key building services design topics. The guidance given complements that in CIBSE Guide K, Electricity in Buildings, and is presented in a format that can be easily incorporated into a firm’s quality assurance procedures. From personal experience I have seen the benefit of such quality procedures. Once embedded within a process information management system, the guidance in this book will ensure consistent and high quality design information. When used for validation and verification, the design checks and procedures can also make a key contribution to a risk management strategy. The easy-to-follow layout and the breadth of content makes Design Checks for Electrical Services a key document for all building services engineers.

  • Using K-Factors with the PH721 Application Note AF-137
    Ventilation Test Instruments Using K-Factors with the PH721 Application Note AF-137 Capture Hoods and Correction Factors (K-Factors) In an ideal world, all capture hoods would provide accurate readings in all flow conditions. This would be true regardless of diffuser size, shape, throw pattern or delivery duct parameters such as shape, size, construction material and proximity of dampers or elbows. In the real world, however, all of these variables can affect the performance of a capture hood. To obtain the most reliable measurements with a capture hood, therefore, it is necessary to use correction factors, or K-Factors, to account for these varying flow effects. The need for K-Factors has been recognized by the most respected organizations in the Heating Ventilating and Air-Conditioning profession, who recommend1-5 the use of correction factors when using any capture hood. ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc.) recommends1 that, “All flow measuring instruments should be field verified by running pitot-tube traverses to establish correction and/or density factors.” ASHRAE also recommends2 & 3 comparing duct traverses to capture hood readings for performance checks in the field. Similarly, AABC (Associated Air Balance Council) recommends5, “take a traverse of the duct and determine correction factors as necessary.” The Importance of K-Factors If measurement accuracy is important, then the use of K-Factors is imperative. As stated earlier, it is well known that many factors affect readings taken with capture hoods. The uncertainties introduced by the wide variety of possible flow conditions make K-Factors vital in achieving accurate capture hood measurements.

  • TSI Getting the Data You Need with Particle Measurements Application
    GETTING DATA YOU NEED WITH PARTICLE MEASUREMENTS APPLICATION NOTE ITI-075 (A4) By Patricia B. Keady TSI Incorporated Shoreview, Minnesota Reprinted from Indoor Environment Connections November 2000, Volume 2, Issue 1 Particles, large and small, are an important factor in maintaining good indoor air quality. Control measures, such as improved housekeeping, upgraded filters, or proper exhaust design, are usually straightforward actions. However, choosing the proper control depends on having the correct data for decision-making. Many instruments, employing various technologies, are currently available to provide this real time information. The question is ―Which technology is right for my application?‖ Photometers, optical particle counters (OPCs) and condensation particle counters (CPCs) all measure airborne particles in real time. Each technology has a unique sensitivity to specific particle characteristics such as size, mass and refractive index. Table 1 summarizes the basic performance differences. Note in particular the size range for each and the upper limit of the number concentrations between OPCs and CPCs. Table 2 summarizes typical applications for each measurement technology. ________________________________ TSI and TSI logo are registered trademarks of TSI Incorporated. Photometers Often used for industrial workplace studies and emissions monitoring, photometers are well-suited for assessing human exposure to specific size fraction aerosols in real time. They use conventional light- scattering technology to closely estimate particulate mass concentrations. The operation of a typical photometer is shown in Figure 1. A sample is drawn into the instrument by a continuously running pump. The size fraction of interest is aerodynamically ―cut‖ from the air stream at the sample inlet using either an impactor or a cyclone.

  • THE VALUE of BREEAM I
    BREEAM Cover Blue_Guide Cover 22/08/2012 15:52 Page 1 FOREWORD ‘As we look to improve the performance of our buildings, both new and existing, it is important to understand the effect of rating tools like BREEAM and how they are perceived and applied by a range of stakeholders. I therefore welcome this independent research by BSRIA, which not only gives a very positive reflection on the progress that BREEAM has made in the market, but also sets an important agenda for BRE as it starts its next update and plans for a “next generation” BREEAM. This will take account of wider social and economic dimensions of more sustainable buildings, as well as a need to complement the rapidly growing use of techniques such as Building Information Modelling (BIM). In a rapidly changing world, sustainability factors are increasingly becoming essential elements of ‘good quality’ buildings that maximise benefits for people while minimising negative impacts on the environment. Nothing stands still for long! This report shows the value – in many forms – that can be derived from a consistent approach to measuring and benchmarking the design and performance of buildings, and unless we do that much more widely, we will fail to make the gains that could benefit so many people. The report also provides important feedback for BRE as the owners and operators of BREEAM, and as the industry’s needs and demands change ever more rapidly, it is essential to take on board customers’ feedback to inform the further evolution of the tool. I look forward to working with BRE to engage the industry to ensure we all respond to these challenges.

Wolpert Faculty of Architecture, Universidad Nacional Autónoma de México ABSTRACT: Architecture, before casting its sublime plastic and aesthetic shed adding to cultural fabric, provides shelter as a response to an aggressive surrounding, as interpreted by human beings. There is then a practical utility in its origin. It follows that a building should operate efficiently to fulfill this primary goal. Architecture is a public art that has its origin in the need for shelter; then it is only caustic for it to consider the environment and energy ratios in its interpretation and to promote a friendly dialogue there too.
