In this module, various ways buildings affect the environment and the characteristics of sustainable buildings are discussed.

Learning objectives

After reading this module, students should be able to

  • understand the various ways buildings affect the environment
  • describe the characteristics of sustainable buildings

Introduction

Buildings present a challenge and an opportunity for sustainable development. According to the most recent available Annual Energy Outlook from the U.S. Environmental Information Administration, buildings account for about 39% of the carbon dioxide emissions, 40% of primary energy use, and 72% of the electricity consumption in the U.S. Additional information from the U.S. Geological Survey indicates that 14% of the potable water consumption occurs in buildings.

Globally, buildings are the largest contributors to carbon dioxide emissions, above transportation and then industry. The construction of buildings requires many materials that are mined, grown, or produced and then transported to the building site. Buildings require infrastructure including roads, utility lines, water and sewer systems. People need to be able to get to and from buildings to work, live, or take advantage of the services provided within them. They need to provide a safe and comfortable environment for the people that inhabit them.

It is possible to design and construct fully functional buildings that have far fewer negative environmental impacts than current norms allow. Beyond benefitting the environment, green buildings provide economic benefits including reduced operating costs, expanded markets for green products and services, improved building occupant productivity, and optimized life-cycle performance. Green buildings also offer social benefits that range from protecting occupant comfort and health, to better aesthetic qualities, less strain on local infrastructure, and overall improvement in quality of life.

In 1994, a group of experts was brought together by the National Renewable Energy Laboratory (NREL) to develop a pathway and specific principles for sustainable development. According to these principles, building should be:

  • Ecologically Responsive : The design of human habitat shall recognize that all resources are limited, and will respond to the patterns of natural ecology. Land plans and building designs will include only those with the least disruptive impact upon the natural ecology of the earth. Density must be most intense near neighborhood centers where facilities are most accessible.
  • Healthy, Sensible Buildings: The design of human habitat must create a living environment that will be healthy for all its occupants. Buildings should be of appropriate human scale in a non-sterile, aesthetically pleasing environment. Building design must respond to toxicity of materials, care with EMF, lighting efficiency and quality, comfort requirements and resource efficiency. Buildings should be organic, integrate art, natural materials, sunlight, green plants, energy efficiency, low noise levels and water. They should not cost more than current conventional buildings.
  • Socially Just: Habitats shall be equally accessible across economic classes.
  • Culturally Creative: Habitats will allow ethnic groups to maintain individual cultural identities and neighborhoods while integrating into the larger community. All population groups shall have access to art, theater and music.
  • Beautiful: Beauty in a habitat environment is necessary for the soul development of human beings. It is yeast for the ferment of individual creativity. Intimacy with the beauty and numinous mystery of nature must be available to enliven our sense of the sacred.
  • Physically and Economically Accessible: All sites within the habitat shall be accessible and rich in resources to those living within walkable (or wheelchair-able) distance.
  • Evolutionary: Habitats' design shall include continuous re-evaluation of premises and values, shall be demographically responsive and flexible to change over time to support future user needs. Initial designs should reflect our society's heterogeneity and have a feedback system.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
