Relating LEED AP Growth to Green Building in the US LEED AP Data through Feb 10, 2010 March 31, 2010 Analysis Joint work with USGBC
Who is under represented relative to the size of the real estate industry? • Appraisers – only 16 LEED APs in the country. • Lenders – only 41 • Thus the problem of appraising and financing LEED property.
Density of Total LEED APs By State Wash DC not viewable here.
LEED APs Per Capita Wash DC Correlation of LEED AP’s Per Capita with # Leed Buildings LQ = .942
LEED Buildings Location Quotient=((state pop/US pop)/(# state cert/total US cert)) #1 Wash DC #2 OR #3 VT #4, 5, 6 & 7 are WA, CO, MA, ME
Relative to All CRE Buildings Which States are the Least Green?

Explaining the Location of LEED BuildingsLEED LQ is the Dependent Variable • R Square = 0.957 • Adjusted R Square = 0.887
Using LEED AP’s Per Capita Explains LEED Building Efforts (or vice versa) • R Square 0.934 • Adjusted R Square 0.931
Relative (Higher) Rents Alone Explain More Than Rent Differentials in Terms of Where Developers Build Green • R Square 0.306 • Adjusted R Square 0.267
Summary on Regression Analysis • It is impossible to know (on this work to date) if we have LEED AP’s in areas with demand for LEED Buildings or if there are areas spawning LEED AP’s that in turn drive more LEED development. • Yet we see a very strong correlation between LEED AP’s and Buildings and little correlation with GDP growth, population growth or even rent differentials (LEED rents above non-LEED rents) • We do see more LEED buildings in those markets with relatively higher rents in absolute dollars. • We still need to investigate regulatory effects and other possible drivers of green real estate. • We need to drill down on some cities as well.
Summary • Incentives and regulation matter • Many states, i.e. CA, and cities with higher penetration of LEED buildings have mandated green buildings, i.e. San Francisco, Houston, Washington DC. (See Eugene Choi, 2011) • Higher rents also matter. Cities where rents are relative high compared to the US average tend to observe higher penetration rates. • It is not clear whether LEED AP’s drive more LEED building or if LEED building drives the presence of LEED AP’s but there exists an extremely high correlation between the presence of LEED buildings and LEED AP’s.
