Green Building Industry

• Market Study and Trends
• A study published by McGraw-Hill Construction and
  the National Association of Home Builders (NAHB)
  is reporting that interest in the Green Building
  Materials Industry grew by 20 in 2006 and will
  see another 30 in 2007. The report is also
  projecting the industry will grow to be a 38
  Billion Dollar industry by the year 2010.
• Many municipalities across the nation are
  requiring Leadership in Energy and Environmental
  Design (LEED) certification to make their
  communities more sustainable. Cities like
  Scottsdale, Arizona and Santa Fe, New Mexico are
  passing codes and incentives to Build Green.

Sustainable Design

• Sustainable design (also referred to as "green
  design", "eco-design", or "design for
  environment") is the art of designing physical
  objects and the built environment to comply with
  the principles of economic, social, and
  ecological sustainability. It ranges from the
  microcosm of designing small objects for everyday
  use, through to the macrocosm of designing
  buildings, cities, and the earth's physical
  surface. It is a growing trend within the fields
  of architecture, landscape architecture,
  engineering, graphic design, industrial design,
  interior design and fashion design.
• The essential aim of sustainable design is to
  produce places, products and services in a way
  that reduces use of non-renewable resources,
  minimizes environmental impact, and relates
  people with the natural environment. Sustainable
  design is often viewed as a necessary tool for
  achieving sustainability.
• Green design is considered a means of reducing or
  eliminating environmental impacts while
  maintaining quality of life by using careful
  assessment and clever design to substitute less
  harmful products and processes for conventional
  ones.

Native American Cultural Philosophy

• The Navajo Culture promotes a philosophy
  Hozhoogo Nashaa Dooleel. The meaning
  translates to May I walk in beauty, harmony and
  balance with my surroundings, and is a
  philosophy aligned with the core principles of
  Sustainable Design.
• The cultural philosophies of many Native Peoples
  and the core principles of Sustainability
  reemphasize a foundation that has been there all
  along. This just needs to be underscored by our
  planning and development.

Green Building Tips

• Being Green
• First, a little self-assessment is in order. Ask
  yourself, how green am I? There are many shades
  of green, each with their own motivations and
  levels of commitment. Are you interested in
• Building homes that make the best use of energy
  resources?
• Durability?
• Producing less material waste?
• The broader environmentally based philosophies
  that green building relates to?
• Take a look at the technologies that you
  regularly feature in your building projects. Do
  any of them align with any of the principles of
  green building described above? If so, consider
  highlighting the green aspects of your current
  practices in your marketing and advertising
  efforts. If customers appreciate these benefits,
  then you can start using additional products that
  provide similar benefits.

76
Green Building Trends

• Low or No-VOC Paints While many paints contain
  high-levels of volatile organic compounds (VOCs)
  that diminish air quality and may be detrimental
  to the health of those who breath them,
  alternatives are now available that release
  little or no VOC pollutants. These latex-based
  paints are durable, cost the same as paints that
  contain VOCs, are high quality, and do not
  contaminate a home's air supply.
• Cement substitutes According to Environmental
  Building News, the annual US production of cement
  creates as much greenhouse gases as the operation
  of 22 million compact cars. But by-products of
  other energy processes exist that can be
  efficiently used to create environmentally
  friendly alternatives to cement. Fly ash, slag,
  silica fume, and rice hull ash are gaining
  popularity among builders due to their strength,
  durability and low-toxicity.
• Plumbing Manifolds Manifold plumbing systems are
  control centers for hot and cold water that feed
  flexible supply lines to individual plumbing
  fixtures. Easy to install, they also reduce heat
  loss and provide steady water pressure and faster
  hot water delivery.
• Bamboo Flooring A plentiful natural resource,
  bamboo is gaining popularity among many builders
  due to its durability and attractiveness. Because
  bamboo grows very quickly, it is a more easily
  renewable resource than hardwood. Although all
  bamboo flooring used in the US is imported from
  the Pacific Rim, it can be readily delivered to
  US job sites within a few days.
• Rainwater harvesting Water is a valuable
  commodity. Collecting and reusing rainwater for
  landscape irrigation saves money and reduces the
  demand on the water supply
