Introduction

Since the Industrial Revolution the world has witnessed

incalculable technological achievements

population growth

corresponding increases in resource use

“Side effects” of all the activities and achievements include:

pollution, landfills at capacity, toxic waste, global warming, resource and ozone depletion, and deforestation.

All these efforts are straining the limits of the Earth’s “carrying capacity”— its ability to provide the resources required to sustain life while retaining the capacity to regenerate and remain viable.

Building Industry- Facts

Construction

Population Vegetation

Air Quality Climate

Transportation Watersheds

1/6 of the world’s freshwater withdrawals

1/4 of world’s wood harvest

2/5 of world’s material & energy flows

Building Industry in US Represents more than 50 percent of the nation’s wealth

New construction and renovation activity amounts to approximately $800 billion

Represents 13 percent of the GDP

Employs over ten million people

C&D debris comprise approximately 15 to 30 percent of all waste disposed of in landfills

The resources required to create, operate, and replenish this level of infrastructure and income are enormous, but diminishing

To remain competitive and continue to expand and produce profits in the future, the building industry has to address the Environmental

and Economic consequences of its actions

Sustainability

SUSTAINABLE DEVELOPMENT

Development that meets the needs of the present without compromising the ability of future

generations to meet their own needs

Green Materials

Materials, production, use and disposal must be safe for the planet. Most of the materials have specific range of conditions in which they best work

Sustainable building materials have the following features:

• Durable and easily maintained

• Less processing required

• Low odor

• Low emitting

• Cost-effective

• Aesthetic

Economics of Green Buildings

Reduction in lighting energy requirements by at least 50 percent

Cut heating and cooling energy consumption by 60 percent

Reduced water consumption by up to 30 percent or more

Lower building operating expenses through reduced utility and waste disposal costs

Lower on-going building maintenance costs, ranging from salaries to supplies

Increase worker productivity by six to 16 percent

Higher property values and potentially lower lenders’ credit risk

Higher building net income

New economic development opportunities

Benefits of Sustainable Construction

Sustainable construction makes wise use of all the natural resources and a 50% reduction in energy use

Improves occupant health, comfort, productivity, reduces pollution and landfill waste that are not easily quantified

A sustainable building may cost more up front, but saves through lower operating costs over the life of the building

Building is designed as one system rather than a collection of stand-alone systems with the help of the integrated system approach

Future of Sustainable Buildings

• Further research

• Successful examples of Sustainable buildings

• Newer, efficient and healthier technologies

• Availability of computer software programs to identify and evaluate options for a building project

• Governmental support

• An active participation from every sector of the society

Case Study- The Dalles Middle School

(Oregon) Problem: Poorly built middle school in a landslide areaIn 1955, to meet the sudden influx of students, temporary facilities were constructed with an expectant life of 20 years, but were used for 45 yearsBy 2000, the State Fire Marshall closed down the facility with the decision to build a new school

Building Design

Heating and cooling are a large part of the energy use of a school building

The high temperature ground water from the landslide area was used to provide both heating and cooling using geothermal principles

It is one of the first schools in the nation that is heated and cooled with the very ground water that caused the landslides

Lighting

Daylighting & Skylighting- Incorporated lots of natural light to reduce the need for electric lighting and the associated increase in the air conditioning load

Energy efficient fluorescent T5s installed in classrooms

Natural Ventilation

Operable windows pull fresh air into one side of the classroom, while ventilation stacks pull the air out on the opposite side of the classroom

At extreme temperatures, automatic backup mechanical ventilation systems used

Application of Concepts of Sustainability

Use of paints and sealers with low or no-volatile organic compounds (VOCs)

Reclaimed ground water to irrigate the ball fields.

Exterior lighting directed downward to reduce night light pollution

Mechanically zoned science classrooms to avoid exposure to hazardous chemicals

Stained the concrete walls to blend with the colors of the natural landscape

Use of ceiling tiles produced from 75 percent post-consumer recycled waste

Results

60 percent cost reduction in energy expected

Students performed better with the skylights and windows that bring natural, non-glare light inside the classroom

High performance school building emerged that will prevent pollution, save energy, natural resources and money

Improved Indoor Air Quality and occupant comfort due to no-VOC emissions from building materials.
