Building Energy Benchmarking and Disclosure in US Cities

Building Sector Greenhouse Gas Emissions Percentage of Total Carbon Emissions from Building Sector 75 75 74 70 65 62 51 38 US Chicago Dallas Minneapolis New York City Philadelphia Salt Lake City Washington, DC The building sector is the dominant user of energy and generator of CO2 emissions in the U.S. This is more true in cities due to density.

- 9. International Policy Timeline 1997: Denmark requires energy certification for homes and buildings 2004: Norway, part of the European Economic Area, formally agrees to implement the EPBD and building certification requirements 2007: Brazil adopts voluntary building rating regulations that become mandatory in 2012 2010: EPBD Recast The EPBD is recast to strengthen the energy performance requirements for all EU Member States 1999: Australian Capital Territory requires energy certification for homes 1996 1997 1998 1999 2000 2001 2002 2002: The European Parliament adopts the Energy Performance of Buildings Directive (EPBD), requiring all EU Member States to establish mandatory energy certification schemes for homes and buildings 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2008: China adopts a mandatory energy rating program for government buildings. 2008: Turkey adopts a mandatory certification scheme 2010: Australia enacts mandatory energy rating for commercial structures.

- 12. NUMBER OF PROPERTIES COVERED ANNUALLY Each year, existing policies will impact more than 51,000 properties Boston 1,600 Chicago 3,500 New York City 15,300 Philadelphia 1,400 Seattle 3,600 Washington State 4,600 Austin 2,800 San Francisco 2,700 Minneapolis 625 Washington, DC 2,000 California 13,600 Source: IMT
- 13. BUILDING AREA (IN SQUARE FEET) COVERED ANNUALLY Totaling approximately 5.8 billion SF of floor space in major real estate markets Chicago 900 million SF Boston 250 million SF Philadelphia 244.5 million SF Seattle 295 million SF Washington State 247 million SF Austin 113 million SF California 347 million SF Minneapolis 110 million SF Washington, DC 357 million SF New York City 2.8 billion SF San Francisco 205 million SF Source: IMT
- 14. Early Energy Intensity Findings in New York City The poorest performing buildings use 4 to 8 times the energy of the highest performing buildings. By improving the poor performers citywide energy reductions of 18% to 31% could be achieved.
- 15. Takeaways Boldest action is in cities - Federal outlook remains uncertain; state and local action to continue Leading cities are looking beyond disclosure - Integrated policy frameworks emerging with focus on poor performers Support from business sector is critical

Notas do Editor
- Early Studies have been helpful, more research needed
- In large cities with significant public transportation, buildings typically account for 70% or more of CO2 emissions and energy usage.There are two types of policies that regulate energy consumption in buildings: building codes, and energy performance policy.
- This view is a little simplified, but in general, building codes touch the building at initial construction and then again during renovation. Energy Performance Policy complements traditional building codes by focusing on the operational phase of the building lifecycle.
- NewYork City: Properties over 50,000 SF account for ~2% of building stock by number, but 50% of floor area.
