A GREEN CONSTRUCTION

Green construction, Green Buildings is a practice of building and maintenance of the buildings which goal is a decrease in an energy and material resources consumption level throughout all life cycle of a building strarting from a site choice for designing, construction, maintenance, repair until destruction.

Other goal of green construction is a preservation or improvement of quality of buildings and their internal environment comfort. This practice expands and supplements classical structural designing with concepts of economy, utility, durability and comfort.

The Green Standards are standards, designing and construction certification rating systems which structure a green building comprehensively. The green standards have a vocation to regulate a sustainable method in construction and estimate a degree of conformity of buildings to the initial principles.

The green building standards preparation and introduction stimulate a development of business, innovative technologies and the national economy, improve a quality of a society’s life and the environmental conditions. It is the tool of a smart economy – it saves money at all stages and promotes the ntegration into the global community, it is a key to foreign investments and a worldwide recognition.

A Necessity of introducing the "green" standards:

A sharp decrease in environmental pollution.
Decrease in consumption of thermal and electric energy no less than 50%.
A centralised supply of all kinds of energy need absence.
Decrease in public utilities tariffs no less than by 15%.
Reduction of a water consumption by 40%.
Comfortable environmental conditions.
Up to date landscape and architectural concepts.
Investments Payback Period from 3 to 5 years.

Systems of the international green certification

Devised by the UK BREGlobal organization in 1990 the BREEAM (BRE EnvironmentalAssessmentMethod) buildings environmental efficiency estimation method has become the first international green certification system.
The BREEAM System is one of the most well-known and widespread methods of a buildings environmental efficiency estimation. The BREEAM defines standards of sustainable designing and construction and makes it possible to compare various buildings as to a level of their environmental impact. Currently:

30 250

BREEAM Accredited Professionals

116 000

Certificated Construction Units

714 000

The Registerred Construction Units

LEED (The Leadershipin Energy and Environment Design)

The Rating System of Voluntary Environmental Certification for so-called Green Buildings.
The system has been devised in 1993 by the U.S. Green Building Council as the green building standard of measurement of energy efficiency and ecological compatibility of projects and buildings. The LEED does not replace the regulations requirements adopted in various states of the world (the National Standard Specifications, the Construction Rules and Regulations) by itself, the system supplements it only by a more perfect, up to date the quality assessment criteria. At present:

30 000 individual members.
18 000 member companies.
160 470 LEED accredited professionals.
525 years (man-hours) spent on projects standard preparation in 117 countries as of 2010.
7 100 000 000 sq. metres of a certificated commercial real estate area.

5 462 certificated commercial buildings.
5 988 certificated private buildings.
27 696 registered commercial buildings.
24 939 registered private buildings.
