13) Sustainable Planning Pathway
(Date of Publication = 11th January, 2014)
Sustainable building design, construction and operation require innovations in both engineering and architecture management areas at all stages of a building’s design and life. The lifespan of buildings is composed of a series of interlocking processes, starting from initial architectural and structural design, through to actual construction, and then to maintenance and control as well as to eventual demolition or renovation of buildings. Inside this lifespan, essential requirements are generated from considerations of social, environmental, and economic issues for high efficient energy-saving building systems in compliance with building codes and regulations. In this regard, building assessment is becoming popular in order to have a standard method to evaluate and deign new and existing building d. For example, the U.S. Green Building Council developed the Leadership in Energy and Environmental Design (LEED) Green Building Rating System as a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. Next paragraph will present concept pathway towards Sustainability.
1) Thermal envelope is exceptionally energy efficient, including the insulation system, window and door selections, and extensive measures to control air leakage. Selection of appropriate foundation thermal protection is also vital which leads to minimizing energy waste.
2) Sustainable site considerations taken into account including orientation, local vegetation, proximity to adjacent structures, distances to water bodies and roadways.
3) Architectural design must be responsive to the local climate to maximize the benefits of passive solar heating, natural gains-avoidance, cooling strategies and the most important is urban context.
4) Exterior means colors of building surfaces need to be tuned to the climate, reducing solar driven loads.
5) Electric demand reduced to micro-load levels by incorporating super-efficient and right sized appliances, mechanical systems, plug-loads.
6) Water consumption reduced to the absolute minimum while maintaining high levels of consumer satisfaction; particularly the hot water service system.
The Diagram is generated to show how the system should work in terms of processes for giving picture of pathway to architects, civil engineers, building engineer and architectural engineers
