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”.
The Energy Conscience Consumers
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.
Sustainable Design….Sustainable Development….Design with Nature Environmentally Sensitive Design….Holistic Resource Management ….Green Architecture….what ever it is you term it, it is the same concept.
Traditional Sustainable Model
Traditional Pillars of Sustainable DesignTriple Bottom-Line Economics
Are the Local economies built in. Local opportunity, access, longevity. How can Critical Mass be achieved. (people)
Environment Preservation of natural environment Limited impact resources Connectivity with open space/outdoors.
Social Social network for sense of community. Limited strain on social programs and resources. Inclusive of all users.
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.
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
