Operations and maintenance optimization

It does not matter how sustainable a structure might have been constructed or designed, but it can only stay like that if is is properly maintained and operated responsinbly. Guaranteeing operations and maintenance - O&M – staff are a component of development and planning prosses of a project that will assist in retaining the green principles employed at the project’s onset. All green building aspects are incorporated into the O&M segment of the life of a building. Adding novel green technologies is also under the O&M personnel. As much as waste reduction goals might be employed in the design, demolition and construction stages of the life-cycle of a building, it is within the O&M stage that green approaches for instance air quality enrichment and recycling occurs.

                                                                                                                  

Waste reduction

Green architecture also aims to diminish waste of materials, water and energy during construction. During construction, one aim ought to be reducing the material quantity used in landfills. Buildings that are well designed also assist in diminishing waste quantities produced by the users as well; via provision of on-site answers for instance compost bins to trim down matter that would have gone to landfills.

When structures cease to be useful, they are normally demolished and disposed to landfills. Deconstruction is an approach to harvest what is generally regarded as waste and retrieving them as valuable materials for building. Prolonging a structure’s useful life also diminishes waste – construction materials for instance wood are easy to work besides being light and they make renovations simpler.

To diminish the effects of plants for water treatment and wells, there are a number of options that can be employed. Waste water and Greywater from washing maschines or dishwashing can be employed for irrigation of the sub-surface, or can be treated for non-potable utilities for example washing cars and flushing toilets. Rainwater collectors can be also employed for comparable purposes.

Wastewater treatment approaches that are centralized can use a lot of energy besides being costly. An option to this is conversion of wastewater and water into fertilizer, which averts such expenses and confirms other advantages. Human water can be collected at the origin and run into a biogas plant that is semi-centralized with other waste that is biological, and liquid fertilizer is generated. Such practices are a platform for organic-nutrient soils besides creating carbon sinks that get rid of carbon dioxide within the atmosphere, triggering emission of greenhouse gas. Artificial fertilizer production is also way costly in terms of energy than this procedure.

                                                                                                                            

Cost and payoff

One issue that has come under criticism concerning environment friendly structures is the cost. Modern technologies, new appliances and photo-voltaics have a tendency of being expensive. Majority of green buildings have a price tag premium of less than 2%, but acquiesce 10 times as much over the builkding’s entire life. The bone of contention is the life-cycle cost pitted against up-front cost knowledge. Money is saved via effective utility use which comes from diminished energy bills. Moreover, higher student or worker productivity is a factor concerning cost and savings deductions.

Studies have indicated that fro over a time span of two decades, a number of green buildings have yielded a range of $53 to $ 71 per square foot return in terms of investment. Further studies on commercial markets of real estate have also confirmed green structures rentability investments, indicating that LEED buildings realize considerably occupancy rates, sale prices and higher rents besides lower rates of capitalization potentially revealing lower risks of investment.

                                                                                                                               

Regulation and operation

As a consequence of amplified interest in green construction practices and concepts, several organizations have come up with developed standards, rating and codes systems that let consumers, building professionals and government regulators accept green construction with confidence. In several cases, written codes enable local governing bodies adopt them as bylaws toward diminishing local environmental effects of structures. For Instance, LEED give credits for elective features of buildings that aid green architecture in classes such as water conservation, building site maintenance and location, occupant health and comfort, building materials and energy. Credit numbers normally determine achievement levels.
