BE2 are the social media advocates behind the Be2camp movement. Since 2008, Be2camp has been championing the use of social media Web 2.0 in the Built Environment (hence Be2).

Since the first Be2camp unconference in London in October 2008, Be2camp people have organised more than 30 events focused on promoting collaboration and co-operation within a better, more sustainable built environment. Key topics have included education, building information modelling, property and real estate, facilities management, the Green Deal, marketing, and river basin management (among other things).

Founded by four practitioners (two in the UK, one in Australia and one in the US), the Be2camp online community is now nearly 700 strong with members around the world.
