  • Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.

  • Welcome to the discipline of building services engineering. You will find that it extends beyond the confines of this text, which concentrates on some of the ‘wet services’ within the building envelope. Part of Chapter 1, however, looks at the building and the way it behaves when it is intermittently heated, as it is important for you to select the plant and design the system that will best suit the building and its use. It is assumed that you have some knowledge of building services.

  • The objective of this study is to assist public authorities to identify and address the future challenges of urban water supply, sanitation, and flood management in cities. In order to do that, this report uses the conceptual framework of Integrated Urban Water Management (IUWM) as a holistic set of planning and management tools incorporating all components of the urban water cycle to help develop efficient and flexible urban water systems in the future. The future of water in African cities: why waste water? argues that a new approach to urban water management is needed in Africa.

  • Water utilities have a long history of planning in preparation for emergencies, particularly natural disasters. But contingency and emergency planning has taken on a new dimension with current concern about potential threats to water system security. The range of crises that have become plausible has expanded, and utilities now are considering more robust security procedures and emergency plans than they have historically had in place. When it comes to ensuring a water system’s security, few utilities, regardless of size or geographic location, can function independently.

  • The inspiration for Building Systems for Interior Designers came when I tried to teach interior design students about all the ways buildings support our activities and physical needs—without an adequate textbook. I needed an approach that supported the special concerns of the interior designer, while connecting those issues to the work of the rest of the building design team.

  • The detection of pharmaceutical residues remained elusive until instruments such as liquid chromatography and mass spectrometry became commonplace in environmental laboratories. The documentation of the occurrence of pharmaceutical residues and endocrine disrupting chemicals in water resources has raused questions about their long-term effects in the ecosystem and their potential effects on human health.

  • The use of aeration in the wastewater treatment field has been in existence for over a century. Each of the authors has been involved with the theory and application of aeration systems for a little less than half a century. It was a daunting task to put together what we considered the important principles underlying the mechanisms involved in aeration and show how they are applied in practical applications.

  • All air-handling units (AHUs) and many terminal units, if they are not self-contained, require a source of heating and/or cooling energy. This source is called a central plant, and the means by which thermal energy is transferred between the central plant and the AHU is usually a fluid conveyed through a piping system. The fluids used in HVAC practice are steam, hot or cold water, brine, refrigerant, or a combination of these. The equipment used to generate the thermal energy is described in Chap. 7. In this chapter we discuss the transport systems. ...

  • In most HVAC systems, the final energy transport medium is moist air—a mixture of dry air and water vapor. This is conveyed through filters, heat exchange equipment, ducts, and various terminal devices to the space to be air-conditioned. The power to move the air is supplied by fans. This chapter discusses fans and duct systems, together with related subjects such as grilles, registers, diffusers, dampers, filters, and noise control.
