  • 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.

  • All solutions to engineering problems start with a calculation or estimation of the duty which must be met (i.e., quantifying the problem). The purpose of heating and cooling load calculations, then, is to quantify the heating and/or cooling loads in the space(s) to be conditioned. Rough estimates of load may be made during the concept design phase.

  • Installation of new system. When no existing system is present, the designer must select the system that is most appropriate for the end user. High temperature hot water and steam/condensate systems are the most common types of distribution systems currently used on military installations. However, a new system should only use the temperatures and pressures necessary to meet the requirements…

  • 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. ...

  • AbstractHumidity is one of the main causes of decay in buildings, particularly rising damp, caused by the migration of moisture from the ground through the materials of the walls and floors via capillary action. This water comes from groundwater and surface water. The height that moisture will reach through cap illary action depends upon factors such as the quantity of water in contact with the particular part of the building, surface evaporation conditions, wall thickness, building orientation and the presence of salts.

  • By definition, air conditioning involves control of the air temperature, humidity, cleanliness, and distribution. It follows that an air-handling unit (AHU) of some kind is an essential part of an air conditioning system, though not necessarily of a heating-only system. The function of the AHU is to provide air at a quantity, temperature, and humidity to offset the sensible and latent heat gains to the space (in the cooling mode) and the heat losses (in the heating mode), while maintaining the required temperature and humidity in the space....

  • Cooling means the removal of heat. In HVAC, a cooling process is usually identified as one which lowers the temperature or humidity (or both) of the ambient air. The effective temperature includes not only the temperature and humidity of the ambient air but also radiant effects and air movement. Some adiabatic cooling processes, i.e., evaporative cooling, do not actually remove any heat, but create a sensation of cooling by lowering the sensible temperature of the air.
