Sustainable engineering

But, the net effect can be a greater reduction of pollutant emissions and effluents than treating each stack or pipe as an independent entity.

This is a foundation for most sustainable design approaches, i.e. conducting a life-cycle analysis, prioritizing the most important problems, and matching the technologies and operations to address them.

Green engineering recognizes that these processes are often inefficient economically and environmentally, calling for a comprehensive, systematic life cycle approach.

It is easy in retrospect to criticize these decisions, but many were made for noble reasons, such as fire prevention and durability of materials.

However, it does illustrate that seemingly small impacts when viewed through the prism of time can be amplified exponentially in their effects.

A life cycle analysis is a holistic approach to consider the entirety of a product, process or activity, encompassing raw materials, manufacturing, transportation, distribution, use, maintenance, recycling, and final disposal.

Once the quantities of various components of such a flow are known, the important functions and impacts of each step in the production, manufacture, use, and recovery/disposal are estimated.

[6] Residential sector itself uses 18%[7] of the total energy generated and therefore, incorporating sustainable construction practices there can be significant reduction in this number.

Sustainable urban design and innovation: Photovoltaic ombrière SUDI is an autonomous and mobile station that replenishes energy for electric vehicles using solar energy .
Worlds first solar clock built in 1983, located in Hibiya Park, Japan. Tile clock in a field of grass with Solar panels located perpendicular of each other, going towards 12 o'clock, 6 o'clock, 3 o'clock and 9 o'clock. The clock hands move every minute with energy provided from the sun. This was built to help with sustainable engineering and the environment.
Green and White Propel gas pump with the labels biodiesel and FlexFuel on it. White pickup truck in background filling up gas tank. Gas pump has biodiesel fuel rather than regular gasoline. Biodiesel fuel is made from plants or animals and reduces pollution and helps with sustainable engineering.
