Every day the word "Green" enters our lives. We read about Green in the news, we see it on TV and we hear about it on the radio, but what is it and how does it affect us? When it comes to mechanicals, (HVAC/R, Plumbing and Electrical) "Green" means maximizing the energy efficiency of existing equipment, specifying the most efficient systems available for the application and the available budget, using renewable and sustainable fuel sources, and conserving water. Both commercial and residential owners want to be Green and reduce energy consumption. In fact, everyone wants to reduce their energy costs. Consumers want contractors and technicians to be aware of the various methods employed in reducing energy consumption and conserving water. They want contractors and technicians who are knowledgeable about energy conserving methods and new technologies. Green Awareness is designed to provide a basic understanding of Green concepts, terminologies, systems, and the latest in Green mechanical technology. The manual contains four main sections: Section 1 Core knowledge of Energy Management and Analysis Section 2 Green Heating - Ventilation - Air Conditioning - Refrigeration Section 3 Electrical Generation and Consumption Section 4 Green Plumbing
Refrigeration, Air Conditioning and Heat Pumps, Fifth Edition, provides a comprehensive introduction to the principles and practice of refrigeration. Clear and comprehensive, it is suitable for both trainee and professional HVAC engineers, with a straightforward approach that also helps inexperienced readers gain a comprehensive introduction to the fundamentals of the technology. With its concise style and broad scope, the book covers most of the equipment and applications professionals will encounter. The simplicity of the descriptions helps users understand, specify, commission, use, and maintain these systems. It is a must-have text for anyone who needs thorough, foundational information on refrigeration and air conditioning, but without textbook pedagogy. It includes detailed technicalities or product-specific information. New material to this edition includes the latest developments in refrigerants and lubricants, together with updated information on compressors, heat exchangers, liquid chillers, electronic expansion valves, controls, and cold storage. In addition, efficiency, environmental impact, split systems, retail refrigeration (supermarket systems and cold rooms), industrial systems, fans, air infiltration, and noise are also included. - Full theoretical and practical treatment of current issues and trends in refrigeration and air conditioning technology - Meets the needs of industry practitioners and system designers who need a rigorous, but accessible reference to the latest developments in refrigeration and AC that is supported by coverage at a level not found in typical course textbooks - New edition features updated content on refrigerants, microchannel technology, noise, condensers, data centers, and electronic control

Are rooms of your house uncomfortable or unusable at different times of the year? Is your home drafty in winter? Do you get hit with a wave of heat walking upstairs in summer? Are mold or pests frequent problems in your home? Do you get big icicles in winter? Do you suspect your home is making you sick? Do you sleep better out of your house? Do you have a damp, dank basement? How about air quality problems like dust or odors? Are you ready to solve those problems? Then this book is for you.Before you can solve a problem, you need to understand what is causing the problem. This book explains how your home actually works so you can address root causes, not symptoms. We've seen far too many folks waste thousands of dollars addressing the wrong problem. Armed with this book, you can find the right pros to solve problems, understand if the work was done right, and even DIY many things yourself.This is the book I wish I had when I entered the Home Performance eld. It connects theory to action and shows real world examples of work being done and the results achieved. It assumes you're a building science novice as well as smart and willing to learn.You'll learn about how your home works, what to look for in a new heating and cooling (HVAC) system, what kinds of insulation work best and why, how to choose and install the right bath fan, and more. Everything in this book is backed up by field experience, data, and an overwhelming passion to do things right the first time.
The design and construction of the appropriate building envelope is one of the most effective ways for improving a building's thermal performance. Thermal Inertia in Energy Efficient Building Envelopes provides the optimal solutions, tools and methods for designing the energy efficient envelopes that will reduce energy consumption and achieve thermal comfort and low environmental impact. Thermal Inertia in Energy Efficient Building Envelopes provides experimental data, technical solutions and methods for quantifying energy consumption and comfort levels, also considering dynamic strategies such as thermal inertia and natural ventilation. Several type of envelopes and their optimal solutions are covered, including retrofit of existing envelopes, new solutions, passive systems such as ventilated facades and solar walls. The discussion also considers various climates (mild or extreme) and seasons, building typology, mode of use of the internal environment, heating profiles and cross-ventilation - Experimental investigations on real case studies, to explore in detail the behaviour of different envelopes - Laboratory tests on existing insulation to quantify the actual performances - Analytical simulations in dynamic conditions to extend the boundary conditions to other climates and usage profiles and to consider alternative insulation strategies - Evaluation of solutions sustainability through the quantification of environmental and economic impacts with LCA analysis; including global cost comparison between the different scenarios - Integrated evaluations between various aspects such as comfort, energy saving, and sustainability
The art and the science of building systems design evolve continuously as designers, practitioners, and researchers all endeavor to improve the performance of buildings and the comfort and productivity of their occupants. Retaining coverage from the original second edition while updating the information in electronic form, Heating and Cooling of Buildings: Design for Efficiency, Revised Second Edition presents the technical basis for designing the lighting and mechanical systems of buildings. Along with numerous homework problems, the revised second edition offers a full chapter on economic analysis and optimization, new heating and cooling load procedures and databases, and simplified procedures for ground coupled heat transfer calculations. The accompanying CD-ROM contains an updated version of the Heating and Cooling of Buildings (HCB) software program as well as electronic appendices that include over 1,000 tables in HTML format that can be searched by major categories, a table list, or an index of topics. Ancillary information is available on the book’s website www.hcbcentral.com From materials to computers, this edition explores the latest technologies exerting a profound effect on the design and operation of buildings. Emphasizing design optimization and critical thinking, the book continues to be the ultimate resource for understanding energy use in buildings.
Readers of this book will be shown how, with the adoption of ubiquituous sensing, extensive data-gathering and forecasting, and building-embedded advanced actuation, intelligent building systems with the ability to respond to occupant preferences in a safe and energy-efficient manner are becoming a reality. The articles collected present a holistic perspective on the state of the art and current research directions in building automation, advanced sensing and control, including: model-based and model-free control design for temperature control; smart lighting systems; smart sensors and actuators (such as smart thermostats, lighting fixtures and HVAC equipment with embedded intelligence); and energy management, including consideration of grid connectivity and distributed intelligence. These articles are both educational for practitioners and graduate students interested in design and implementation, and foundational for researchers interested in understanding the state of the art and the challenges that must be overcome in realizing the potential benefits of smart building systems. This edited volume also includes case studies from implementation of these algorithms/sensing strategies in to-scale building systems. These demonstrate the benefits and pitfalls of using smart sensing and control for enhanced occupant comfort and energy efficiency.
