Sustainable Design • 2005 World Summit’s three pillars of sustainability declaration: • Environment • Society • Economy
Sustainable Design • Sustainable Design Decision Model: • Environmental • Economic • Social • Time / Program • Quality “The old decision model is based on a balance between cost [economic], schedule [program] and quality. However, designers also need to become equally familiar with the effect their decisions have on the environment and human health, safety and comfort [social].” Mendler, S. Odell, W. Lazarus, M A. (2006) The HOK Guide Book to Sustainable Designs. 2nd Edition. New Jersey: John Wiley & Sons, Inc.
Water In Construction 1/6 of this water is used in construction.

Changing Characteristics of Wastewater Higher Strength Wastewater Longer retention times in domestic drainage systems. Increased risk of odour issues. Increased risk of Hydrogen Sulphide generation. Trade Waste Limits COD BOD
The other costs of Water • Generation of Electricity from Thermoelectric Power Stations costs 95 L/kW.h to 142 L/kW.h. • It costs 3.5 kW.h to 4.0 kW.h to produce 1 kL of desalinated water. • For each 1 kL of water delivered by a municipal water supply it costs 0.7 kW.h to 1.2 kW.h (based on traditional surface water systems). • Including supply chains, energy and wastes, it take up to 100 L of water to deliver 1 L of water by a municipal water supply. • Rainwater Tank pumps may cost 1.5 kW.h to 3.0 kW.h to deliver 1 kL of water.
Allied Systems • Fugitive Green House Gas Emissions • Nitrogen Cycle • Phosphorous Cycle
The Future of Plumbing and Construction • The sustainable use of water is going to have an increasing influence in the plumbing and construction industries. • Sustainable Design is more than Environmental Sustainable Design. • Prima-facie Environmental Sustainable Solutions need to be challenged to ensure that the environment is not compromised by incidental threats to the environment. • Projects need to consider the Sustainable Design options that are unique to the location of the project.
