Following a LEED: a knowledge of LEED requirements is becoming necessary for recyclers and subcontractors.Recyclers and subcontractors are increasingly being asked to meet Leadership in Energy anti Environmental Design (LEED) requirements. The environmental scoring system Noun 1. scoring system - a system of classifying according to quality or merit or amount rating system classification system - a system for classifying things , though only a few years old, has quickly taken hold in an era of high energy costs and environmental concerns. Deciding to obtain LEED status generally happens upstream from the subcontractor One who takes a portion of a contract from the principal contractor or from another subcontractor. When an individual or a company is involved in a large-scale project, a contractor is often hired to see that the work is done. level, when an architect, general contractor A general contractor is an organization or individual that contracts with another organization or individual (the owner) for the construction of a building, road or any other execution of work or facility. and customer (developer, property owner or lead tenant) make the decision to strive for LEED points and designation. Slowly, though, subcontractors such as demolition Demolition is the opposite of construction: the tearing-down of buildings and other structures. It contrasts with deconstruction, which is the taking down of a building while carefully preserving valuable elements for re-use. contractors, waste and recycling recycling, the process of recovering and reusing waste products—from household use, manufacturing, agriculture, and business—and thereby reducing their burden on the environment. haulers and mixed C&D recyclers are coming into contact with the LEED requirements in relation to specific bids, jobs and operating procedures. The full roster of LEED scoring is a lengthy one. But within that overall system, categories and subcategories that are most likely to effect demolition and recycling companies can be identified.

Green Building Council (USGBC USGBC United States Green Building Council ), Washington, creators and managers of the LEED system, we are publishing some of those pertinent sections on this and the following pages. In the next issue, we'll talk to subcontractors and others involved in LEED and green building to offers some practical examples of what to keep in mind when approached to work on a project seeking LEED certification points. The following excerpts are taken from "LEED-NC Version 2.2," sub-titled the "Green Building Rating System for New Construction & Major Renovations."

Required or necessary as a prior condition: Competence is prerequisite to promotion. n. 1: Storage and Collection of Recyclables Required Intent Facilitate the reduction of waste generated by building-occupants that is hauled to and disposed of in landfills. Requirements Provide an easily accessible area that serves the entire building and is dedicated to the collection and storage of non-hazardous materials for recycling, including (at a minimum) paper, corrugated cardboard Noun 1. corrugated cardboard - cardboard with corrugations (can be glued to flat cardboard on one or both sides) corrugated board cardboard, composition board - a stiff moderately thick paper corrugated cardboard n , glass, plastics and metals. Potential Technologies & Strategies Coordinate the size and functionality of the recycling areas with the anticipated collection services for glass, plastic, office paper, newspaper, cardboard Cardboard is a generic non-specific term for a heavy duty paper based product. Paperboard
Paperboard is a paper based material. It is often used for folding cartons, set-up boxes, carded packaging, etc. and organic wastes to maximize the effectiveness of the dedicated areas. Consider employing cardboard balers, aluminum can crushers, recycling chutes and collection bins at individual workstations to further enhance the recycling program. MR.

Object-oriented programming offers reusability of code via its techniques of inheritance and genericity. : Maintain 75 Percent of Existing Walls, Floors and Roof (1 Point) Intent Extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and reduce environmental impacts of new buildings as they relate to materials manufacturing and transport. Requirements Maintain at least 75 percent (based on surface area) of existing building structure (including structural floor and roof decking) and envelope (exterior skin and framing, excluding window assemblies and nonstructural roofing material). Hazardous materials that are remediated as a part of the project scope shall be excluded from the calculation of the percentage maintained. If the project includes an addition to an existing building, this credit is not applicable if the square footage of the addition is more than two times the square footage of the existing building. Potential Technologies Consider reuse of existing, previously occupied buildings. including structure, envelope and elements. Remove elements that pose contamination risk to building occupants and upgrade components that would improve energy and water efficiency such as windows, mechanical systems and plumbing plumbing, piping systems inside buildings for water supply and sewage. The Romans had a highly developed plumbing system; water was brought to Rome by aqueducts and distributed to homes in lead pipes—hence the name plumbing from the Latin word plumbum fixtures.

Hazardous materials that are remediated as a part of the project scope shall be excluded from the calculation of the percentage maintained. If the project includes an addition to an existing building, this credit is not applicable if the square footage of the addition is more than two times the square footage of the existing building. Potential Technologies & Strategies Consider reuse of existing buildings, including structure, envelope and elements. Remove elements that pose contamination risk to building occupants and upgrade components that would improve energy and water efficiency such as windows, mechanical systems and plumbing fixtures. MR CREDIT 1.3: Building Reuse: Maintain 50 Percent of Interior NonStructural Elements (1 Point) Intent (Same as for MR Credit 1.1.) Requirements Use existing interior non-structural elements (interior walls, doors, floor coverings and ceiling systems) in at least 50 percent (by area) of the completed building (including additions).

Potential Technologies & Strategies Establish goals for diversion A turning aside or altering of the natural course or route of a thing. The term is chiefly applied to the unauthorized change or alteration of a water course to the prejudice of a lower riparian, or to the unauthorized use of funds. from disposal in landfills and incinerators and adopt a construction waste management plan to achieve these goals. Consider recycling cardboard, metal, brick, acoustical tile tile, one of the ceramic products used in building, to which group brick and terra-cotta also belong.

Redirect recyclable recovered resources back to the manufacturing process. Redirect reusable materials to appropriate sites. Requirements Recycle and/or salvage an additional 25 percent beyond MR Credit 2.1 (75 percent total) of non-hazardous construction and demolition debris.

Mechanical, electrical and plumbing components and specialty items such as elevators and equipment shall not be included in this calculation. Only include materials permanently installed in the project. Furniture may be included, providing it is included consistently in MR Credits 3-7. Potential Technologies & Strategies Establish a project goal for locally sourced materials, and identify materials and material suppliers that can achieve this goal. During construction, ensure that the specified local materials are installed and quantify the total percentage of local materials installed. Consider a range of environmental, economic and performance attributes when selecting products and materials. |
