what is green Building

 

SI 5281: SUSTAINABLE BUILDING (GREEN BUILDING)


In 2011, the Ministry of Environmental Protection and the Standards Institution of Israel decided to make fundamental changes to SI 5281 (in existence since 2005), thereby creating a standard that accurately characterizes green building and the manner of its inspection. To this end, the SII recruited the British consulting firm that wrote the British Standard BREEAM. The firm convened external expert committees composed of people from academia and from the profession, contractors, engineers and Government employees, who worked together and issued a new standard in a record time of just nine months. The new standard, effectively comprising a series of standards that will be updated repeatedly based on current feedback from the field, will be amenable to innovation and changes for the benefit of green building in Israel.
 

What is new in the 2012 standard?


The green building standard of 2005 applies only to residential and office buildings. Following the changes introduced in 2011, a series of standards was written that applies to a large number of both new and existing buildings (building renovations). SI 5281 of July 2011 contains eight parts: general requirements, residential buildings, office buildings, tourist accommodation buildings, retail buildings, educational buildings, healthcare buildings and public buildings. To these eight, two new parts will be added, dealing with the requirements for industrial buildings and for residential neighborhoods. Each part includes the subject area of the Standard and the following characteristics categorized according to chapter: energy, land, water, materials, healthcare and welfare, waste, transportation, and building site management and innovation. The standard is divided into five levels of quality: each level is assigned a score ranging from one star (the lowest score) to five stars (the highest score).

 

The benefits of green building


• Savings of approximately 30% in energy consumption
• Savings of up to 75% in potable water consumption
• Recycling of waste during construction and throughout the building's lifetime
• Improvements in the building interior and achievement of environmental protection due to the use of materials and a work environment that complies with green regulations.

 

The importance of green building


Green building seeks to reduce the negative impact of buildings on the environment. This aim is achieved by using knowledge and technologies to create a sustainable environment that meets the needs of the present generation without compromising that of future generations. The integration of knowledge and green technologies is an ongoing learning process based on architectural and climactic planning principles together with the development of innovative systems. The basis for green planning and green building is architecture that takes account of users' needs and ensures their well-being, combined with planning that takes account of environmental conditions and informed consumption of resources.


Green building is essentially multidisciplinary, referencing different aspects of building, planning and development.
A green building project addresses multiple elements, including savings in energy consumption, water savings, runoff handling, project site selection issues, building density, development of the site's non-built areas, ecology, use of green materials in the building, management of the building site, and the quality of the building for tenants (access to natural light, landscape, airing of interior spaces, etc.).
The importance of green building is expressed in the environmental triangle of economics (monthly financial savings), society and the environment.
Without question, the awareness of developers of condominium complexes and public buildings must be raised about the need to construct green buildings of a high standard for users and for the sake of their health. Numerous studies have shown that green homes reduce the incidence of various chronic illnesses.
 

 The infrastructure at the Standards Institution of Israel


• A professional staff (four green building inspectors)
• Seven technical and general instructors for the Standard
• Submission forms that enable a simulation for an independent assessment based on the uses defined in the Standard.
• Courses for those overseeing green construction
• Service Level Agreement (with binding dates)
• Published price list for the authorities
• A personal contact resident at the SII for each authority engaged in the process and working with the Standards Institution of Israel.
• Building of an online system for the submission of professional material and for scoring simulations (June 2012).

 

Service Level Agreement


• Dispatching a proposal within eight days of receipt of the customer request.
• Sending an invoice and payment instructions within two workdays of receiving the customers approval for the proposal.
• Providing a response within 21 days of the date that professional materials for inspection were submitted.
• Providing immediate marketing approval all along the project milestones (temporary approval).
• A decision of the Professional Committee on Green Building within 21 days of the date that Form 4 is submitted (or equivalent form attesting to compliance with the Planning and Building Law)
• Convening of the Permits Committee to provide final approval for the building within 14 days of the date that the Professional Committee on Green Building was convened on.
• Providing a response within two work days to professional questions concerning clarification of the provisions of the Standard and concerning green building.

 

 

Green building simulator


• The Standards Institution of Israel has launched an innovative simulator intended for the use of those overseeing green construction, developers and contractors. It simulates the process for submission of forms for a project that requires green building approval in accordance with SI 5281.
• The submitter of a proposal for a green building will, with the aid of a personal password and completion of the relevant forms, be able to assess the readiness of the building for green building certification.
