The District/Central Solar Water Heating Systems Design Guide provides recommendations on optimal and reliable configurations of solar water heating systems in different climates, with design specifications, planning principles, and guidelines for these systems. The guidelines are complemented by numerous case studies of successfully implemented solar supported thermal networks along with results of exemplary simulations of different system options based on real world scenarios. This book also discusses the benefits and disadvantages of large-scale centralized versus decentralized solar thermal systems. The guide was developed by government, institutional, and private-sector parties funded by the U.S. Army Installations Management Command (IMCOM), U.S. Army Corps of Engineers (USACE), and the U.S. Department of Energy Federal Energy Management Program (DOE FEMP), and reviewed and approved by ASHRAE Technical Committee (TC) 6.7, Solar Energy Utilization.
Passive solar heating and passive cooling—approaches known as natural conditioning—provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved. Now Dan Chiras, author of the popular book The Natural House, brings those principles up to date for a new generation of solar enthusiasts. The techniques required to heat and cool a building passively have been used for thousands of years. Early societies such as the Native American Anasazis and the ancient Greeks perfected designs that effectively exploited these natural processes. The Greeks considered anyone who didn't use passive solar to heat a home to be a barbarian! In the United States, passive solar architecture experienced a major resurgence of interest in the 1970s in response to crippling oil embargoes. With grand enthusiasm but with scant knowledge (and sometimes little common sense), architects and builders created a wide variety of solar homes. Some worked pretty well, but looked more like laboratories than houses. Others performed poorly, overheating in the summer because of excessive or misplaced windows and skylights, and growing chilly in the colder months because of insufficient thermal mass and insulation and poor siting. In The Solar House, Dan Chiras sets the record straight on the vast potential for passive heating and cooling. Acknowledging the good intentions of misguided solar designers in the past, he highlights certain egregious—and entirely avoidable—errors. More importantly, Chiras explains in methodical detail how today's home builders can succeed with solar designs. Now that energy efficiency measures including higher levels of insulation and multi-layered glazing have become standard, it is easier than ever before to create a comfortable and affordable passive solar house that will provide year-round comfort in any climate. Moreover, since modern building materials and airtight construction methods sometimes result in air-quality and even toxicity problems, Chiras explains state-of-the-art ventilation and filtering techniques that complement the ancient solar strategies of thermal mass and daylighting. Chiras also explains the new diagnostic aids available in printed worksheet or software formats, allowing readers to generate their own design schemes.

Solar Energy, Photovoltaics, and Domestic Hot Water provides a fundamental understanding of heat and energy conversions and of both solar domestic hot water system types with associated components and photovoltaic/inverter system combinations. It provides the information needed to determine and understand the proper siting requirements, the amount of energy needed (based upon usage), the amount of solar energy available, the methods of comparing collectors for both hot water and photovoltaic situations, and the number of collectors necessary for either hot water or electricity. Solar Energy, Photovoltaics, and Domestic Hot Water also details the investment and cost savings advantages of using solar energy through a unique compilation of information and explanations not available in other publications or on the internet. This includes comprehensive financial explanations with examples using basic engineering management analysis methods. These examples include present and future worth relative to break-even costs and cash flow analysis and actual quoted systems and worksheets for typical electrical solar PV and DHW demand scenarios allowing you to calculate your own cost estimates and to evaluate your own projects relative to investment payback. Solar Energy, Photovoltaics, and Domestic Hot Water will enable readers make informed decisions about the economic practicality of solar generation sources for residential or commercial use based upon location, energy demands, associated conventional fuel costs, solar energy system costs, and tax incentives. Provides a fundamental understanding of solar DHW and photovoltaic systems Uses clear guidelines to evaluate solar DHW and photovoltaic systems’ value as a long-term investment vs traditional power and heat generation methods Discusses cost and operating expenses relative to investment and return on capital which will be beneficial to project planners, installers, energy managers, builders and property owners
