Green Building & Energy Efficiency

Capital E was hired by World Bank to help design major new green building investment program ($500 million in 2015). 



Capital E President, Greg Kats, served as the Principal Advisor to Enterprise Community Partners, a billion-dollar affordable housing developer, guiding the firm’s CEO and top management in creating Green Communities, a comprehensive, cost-effective standard for green and healthy design. Enterprise Green Communities has been used as the basis in the design of 60,000 units of affordable housing. It has become the national (and increasingly the international) design standard for green affordable housing.

IPMVP is the international industry standard for efficiency design and documentation and the basis for over $50 billion in energy efficiency investments. Greg Kats co-founded (with Art Rosenfeld) and served as Executive Chairman for 7 years, managing all aspects of industry-wide standard development, including (with the Association of Energy Engineers) the creation of the international M&V training and certification standard for industry professionals (CMVP). IPMVP allows off-balance-sheet efficiency financing, has been translated into 10 languages, is a required design basis for all US federal buildings, and serves as the technical efficiency design standard for LEED. For more see the IPMVP Wikipedia page.


CarbonStar is the first international industry standard for documenting, demonstrating, and specifying carbon intensity of concrete. Capital E President Greg Kats is one of three co-developers of the standard.

Co2 to EE: Leveraging Cap-and-Trade to Expand California’s Energy Efficiency Financing Market. 


CO2toEE would substantially increase funding for deep energy efficiency investments in buildings by providing a mechanism to allow buildings and building owners (including businesses, schools and cities) to document and claim value of CO2 reduction. In evaluation for adoption by state of California. More info

Decarbonizing LEED

LEED (Leadership in Energy and Environmental Design) has become relatively weak on climate, including setting a provisional target for being carbon-neutral by 2050. Capital E President Greg Kats has organized and led an industry effort, supported by 150 founders and early adopters of LEED in pushing USGBC to adopt minimum CO2 reduction requirements for each level of LEED. This effort influenced LEED 4.1 to become more aggressive on climate targets and continues to shape the debate about LEED and climate.
