LECTURE 3 4

Section Objectives

Describe the intent of this category

Define basic concepts and terms

Case studies: examples of best practices

Section Intents:

LECTURE 3 5

LEEDs Objectives

Green building addresses two kinds of problems

related to materials and resources:

Waste management

Life-cycle impacts

LEED recognizes and encourages strategies that

consider materials and resources from a long-

term, life-cycle perspective.

Section Concept:

Life cycle

Life cycle assessment

Life cycle example Cradle to Cradle as opposed to Cradle toGrave;

Cradle to Cradle (C2C) is focusing on:

environmentally sensitive product design and

controlling the generation of waste.

The goal is to reuse rather than retire and dispose and it affects

facilities and equipment alike.

Assessment and Measurements


The Sustainable Forestry Initiative (SFI) label is a sign you are buying

wood and paper products from a responsible source, backed by a rigorous,

third-party certification audit.

LECTURE 3 12

Best Pract ices = RRR :

Reduce construction waste generation

Reuse existing structures

Recycle construction waste

Select non-toxic, recycled content or rapid

renewable materials


Most building materials utilize finite raw resources or resources with long

regeneration cycles.

Utilizing rapidly renewable materials that have less than ten year harvest

periods diminishes the ecological footprint of a building project.

Real life examples:Joe Serna Jr. California EPA Headquarters:

Construction materials salvaged and refurbished

Purchased recycled materials

Used certified-wood base materials FSC wood


Forest Stewardship Council (FSC) provides international leadership

system for building wood products in terms of their environmental source

and social responsible management of the world forests.

Recycled content can be:

post-consumer such as waste generated by households

pre-consumer such as material diverted from waste stream

during the manufacturing process

Section Objectives:



Case study examples of best practices

Section Intents:

Provide systems to ensure a quality indoor

environment

Eliminate, reduce and manage contaminants

Indoor Environmental Quality

LECTURE 3 18

According to trusted source people in US spend90% of their time indoors, where concentrationof pollutants may be significantly higher thanoutdoor levels. Consequently, indoorenvironmental quality is a major concern inbuildings.

Innovation in design

LEED has recognized the following exemplary

performance strategies above and beyond existing

requirements:

Doubling density requirements for Sustainable Sites

credits.

Significantly reducing indoor water use beyond the 40%

requirement.

Significantly diverting construction waste beyond the

requirement of 75%. Providing more day-lighting than the 75% requirement.
