building" . An example of the virtues of an integrated design process is the
collaboration between the mechanical engineer and the architect in designing the
If the architect is designing a super-insulated, high-performing building
envelope that significantly lowers the amount of heat the building requires, the
mechanical engineer should take this into account and design a much smaller heating
and cooling system. If there was no cooperation and strategic thinking between the
architect and the mechanical engineer, and each designed their particular piece of the
building entirely separately from the other, the outcome would be much more
inefficient and costly in both first costs and operations. While there is no officially
accepted definition of green building, Keeler and Burke's book  provides a helpful
framework for what elements any green building project strives to include in its
design and construction.
a. Tackle site-demolition issues and construction-and-packing-waste issues,
as well as waste generated by users of the building
b. Strive for efficiency in a broad area of resource use
c. Minimize the impact of mining and harvesting for materials production
and provide measures for replenishing natural resources.
d. Reduce soil, water, and energy use during materials manufacture, building
construction, and occupant use.
e. Plan for low embodied energy during shipment
f. Proceed logically, as the chain of materials production is traced.
g. Conserve and design for the efficiency of energy consumed by powering
mechanical systems for heating and cooling, lighting, and plug loads.
h. Provide a "healthy" indoor environment
