4 GREEN BUILDING TRENDS 4U

By Jodi Summers

Green building concepts are being embraced with as much wild abandon as kids grasping for the coolest new video game. It started pretty basic – green construction, then evolved into green renovation, and now it’s branching out in all directions. Here are 4 green building trends to watch and invest….

1 - Modular Green Homes – One of the most successful investors in history, Warren Buffett, recently expanded one of his business subsidiaries, Clayton Homes, to produces a line of green modular homes. These 750-square-foot eco homes, dubbed “i-houses,” can be purchased online for less than $75,000. It’s a good bet that if Buffet is invested in it, the area will grow. Our hero is second richest man in the United States with a net worth of $40 billion.

The i-houses are constructed as modules in a factory and then assembled in the field. I-houses are marketed as “affordable luxury in a green, energy-efficient package.”

Beyond Buffett, there are others, such as Zeta Communities and Blu Homes in the green prefabricated market. Modular home construction will be a wise choice for builders going forward because it may allow developers reduce risk, allowing the development of large sites to take place as sales come in rather than building a planned community in larger phases before the units are sold out.

2 – Energy Retrofits – California state measure AB 1103, which requires the tracking of the energy use of all nonresidential buildings for disclosure to prospective buyers and tenants, is a fine example of how critical energy retrofits will be in the future. Much of the country’s real estate is old and wastes energy…eventually these properties will need to be upgraded or replaced. Not to mention, this is a cornerstone of President Obama’s post recession job creation movement.

Energy Star, the government, and local utilities have been offering rebates for property owners on measures like energy audits, insulation and duct sealing. SBI Energy predicts that the U.S. home energy retrofit market will grow about 15 percent per year to $35 billion by 2013, up from $20.7 billion in 2007.

David Leathers, senior vice president of energy services for mechanical contractor Limbach, confides that U.S. commercial building in the U.S. five years or older can likely benefit from a retrofit with payback for most measures taken in less than five years.

3 - Smart Building Materials - Energy-efficient building materials are the frame of green building. Serious Materials recently raised a $60 million third round of venture for the manufacture of energy-saving windows and environmentally friendly substitutes for sheetrock. More good investments - high-efficiency insulation system companies, such as walls with micro-encapsulated phase change materials to stabilize the indoor temperatures in buildings. More…Electrochromic technologies can darken or lighten the tint of a window when in contact with an electrical current, thus managing the amount of sunlight that passes through…Ventilated double-skin facades (already being used in Europe), use inner and outer glass walls with a thin cavity to provide insulation in between for the exterior shell of a building.

4 - More Energy Efficient Energy Codes - The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE ) and the International Energy Conservation Code (IECC) are both developing the latest round of “model codes”— ASHRAE 90.1 and IECC — will likely require a 30 percent increase in energy efficiency.

Congress may soon mandate that all states raise their standards to the newest codes. The American Clean Energy and Security Act passed by the House this year includes a provision that would effectively create a baseline national building energy code by mandating the adoption of a standard set by the Department of Energy, who may very well call on the standards set forth by ASHRAE or IECC.
