Focus groups have pointed out that Las Vegas commercial developers and home builders are behind the curve on green building. Developers are accused of being focused on selling prices rather than cost savings for future years.

According to many design experts, many developers think that it is more expensive to build green. Analysts say that there are more important factors to consider. Like analyzing both the initial cost and operating cost for the next three decades.

Analysts also say that while there would be an increase of 3-5 percent on construction cost, that money could be made up in three years or less.

The hike in cost would be seen once construction costs for a building is processed through the Leadership in Energy and Environmental Design certification.

According to architectural consultant Lynn Simon of California based Simon & Associates there are many features that would benefit new green homes.

Some featured systems are designed to reclaim "blackwater," wastewater from kitchen sinks and toilets. There are also improvements such as photovoltaic panels which convert sunlight to electricity.
