Al Gore delivered the keynote address to green building professionals at the Greenbuild conference. He praised the leadership of the USGBC for bringing real change to the marketplace. He also urged the crowd to take responsibility for expanding green building globally and to call out greenwashing.

This is a round-up of on-the-spot interviews with job seekers who attended the job fair at the Greenbuild Conference that is taking place this week. Attendees were asked what strategies were they using to land a green building job.

The market for green buildings is exploding and the lion’s share of the opportunity exists in retrofits, not new buildings. McGraw-Hill Construction’s latest SmartMarket Report, Green Building Retrofit & Renovation: Rapidly Expanding Market Opportunities Through Existing Buildings, was released at the Green Retrofit Conference in New York recently. The report finds that new buildings represent only 2.5% of the US building market, while retrofitting provides an enormous market opportunity for green builders, owners and building product manufacturers.Currently, green building comprises 5-9% of the retrofit and renovation market activity by value. This equates to a $2-4 billion marketplace for major projects. By 2014, that share is projected to increase by 20-30%, creating a $10-15 billion market for major retrofit projects in only five years.
