Chapter 6 Plumbing Systems  In Chapter 5 we learned to  Design efficient bathrooms and kitchens by stacking and grouping plumbing on common walls. Prepare plans with adequate clearances for plumbing,  Understand the basic components of water supply and waste disposal in a building, and Understand sustainability concerns as related to plumbing systems.  Overview of How Plumbing Works Plumbing systems consist of two primary parts: supply and waste. Supply water enters a building under pressure. This pressure allows the water to reach the upper levels of a building for use. At the entry to the building there is a main water shut-off valve with additional locational shut-offs at each fixture for minor repairs and maintenance.  The Drain-Waste-Vent (DWV) part of the system relies on gravity and water's ability to seek its own level. Wastewater is divided into either black water (potentially containing human waste) or gray water (from sinks, laundry, a...

Chapter 5 Mechanical Systems   In Chapter 5 we learned about, Designing  an effective and sustainable lighting solution, Comparing lamp types and their appropriate uses in an interior, Identifying sustainable lamps and fixture types, Identify lamps and fixture types, Using CRI and CCT to assist in lamp-selection criteria, and Drawing a reflected ceiling plan. Power companies provide electricity for most buildings. This electricity can be generated by several sources, as mentioned in Chapter 4 in the discussion of fuel sources. The single biggest source of energy use in a building is for electric lighting. Thus, this chapter presents the basic principles of electricity and electric lighting. Electricity Electrical current can be either in the form of alternating current (AC) or direct current (DC). In the late nineteenth century, Thomas Edison advanced the electric lamp using direct current. Edison believed that DC power was superior to AC and promoted it as such. Nic...

Chapter 4 Mechanical Systems   In Chapter 4 we learned to, Identify renewable fuel sources, Compare heating systems and cooling systems and methods of heating and cooling, Specify the importance of commissioning of systems with which they are involved, Identify issues of human comfort with regard to HVAC, Show how to apply LEED energy-efficiency credits to a project. Both mechanical and electrical systems require a fuel source in order to operate. The fuels used to generate power come from several sources, some of which are sustainable, and many of which ultimately are not. The US Department of Energy (DOE) acknowledges the following energy sources: bioenergy, coal, electric power, fossil fuels, fusion, geothermal, hydrogen, hydropower, natural gas, nuclear, oil, renewables, solar, and wind. These sources can be subdivided into those that fall under the Renewable Energy/Biomass program and those that do not. Sources of Fuel Bioenergy is produced from organ...
