The Diffusion of Energy Efficiency in Building / Nils Kok, Marquise  McGraw, and John M. Quigley.  UC Energy Institute, Berkeley, Jan. 2011,  34 p. (E3 WP-003)http://www.uce3.berkeley.edu/WP_003.pdfWe  analyze the diffusion  of buildings  certified for energy efficiency  across US property  markets. Using a  panel of 48 metropolitan areas  (MSAs) observed over the  last 15 years,  we model the geographic  patterns and dynamics of  building  certification, relating industry  composition, changes in  economic  conditions, characteristics of the  local commercial property  market,  and the presence of human capital,  to the cross-sectional  variation in  energy-efficient building  technologies and the diffusion of  those  technologies over time.  Understanding the determinants and the  rate at  which energy-efficient  building practices diffuse is important  for  designing policies to  affect resource consumption in the built   environment.
