SI 5281 – Sustainable Construction (Green Construction)

 

In 2011, the Ministry of Environmental Protection and the Standards Institution of Israel decided to revise Israel Standard 5281 (which had existed since 2005), and to create a standard with precise standards for defining a green building. The Institution’s staff enlisted a British consulting firm that authored the British standard BREEAM, and also convened External Expert committees composed of academics, professionals, contractors, engineers, and government employees, who together worked to issue a new standard in the record time of only nine months. The new standard is actually composed of a series of standards, which will continue to be updated over and over again, in accordance with feedback that will be received on an ongoing basis from work in the field. The standard will be open to innovations and changes for the benefit of the promotion of green construction in Israel.

What’s new in the 2011 standard?

The 2005 green construction standard applied exclusively to residential and office buildings, while the 2011 revision includes a series of standards applicable to a large number of both new and existing (under renovation) buildings. In Israel Standard 5281, of July 2011, there are eight parts to the standard: general requirements, residential buildings, office buildings, tourism, trade, educational institutions, health institutions and public assembly institutions. In addition to these existing eight parts, two new parts will soon be added, dealing with requirements for industrial buildings and residential neighborhoods. Each part contains the field dealt with in the standard, and the following characteristics classified by chapter:  energy, land, water, materials, health and welfare, waste, transportation, construction site management, and innovation. The standard is divided into five quality levels, ranked from one star to five stars for the highest quality level.

Advantages of green construction

  • Savings of approximately 30% in energy consumption.
  • Savings in water consumption for about 75% of potable water.
  • Waste recycling during construction and during the life of the building.
  • Better quality of building interior through use of materials with a Green Mark, and a high quality work environment.

The Importance of green construction

The goal of green construction is to reduce the scale of the negative impact that buildings have on the environment, through use of knowledge and technology, in order to create a sustainable environment that meets the needs of the current generation, without endangering the capabilities of future generations. The assimilation of green knowledge and technologies is an ongoing learning process based on principles of architectural and climate design along with development of innovative systems. The keys to green design and green construction are: architecture that takes into consideration the needs of the users and is concerned about their welfare, and design that is mindful of environmental conditions and of intelligent consumption of resources.
Green construction is fundamentally interdisciplinary, and deals with various aspects of construction, design, and development.
A green construction project relates to a number of elements, including: conservation in energy consumption, water conservation, treatment of runoff, issues connected with choice of project site, building density, development of the non-built-up areas of the site, ecology, use of green materials for construction, construction site management, building quality for its residents – access to natural light, landscaping, ventilation of interior spaces, etc.
The importance of green construction is expressed through the environmental triangle of economy (financial savings in monthly expenses), society, and environment.
There is no doubt that awareness must be raised among developers of high-density residential construction and developers of public institutions, for construction of green buildings that provide a high quality of life to the users while safeguarding their health. Many studies show that a green home reduces the incidence of various chronic ailments.
