16. Energy efficiency improvements to existing buildings (1) Changes in energy use from 1999 to 2003 -  Central Library: electricity  30% v Argus House: electricity  32% v Solid waste/Traffic admin: electricity  14% v Madison Comm. Ctr: gas  13% electric  17% v Lubber Run Comm. Ctr: gas  26% elec.  19% v Residential Program Ctr: gas  9% elec.  11%

17. Energy efficiency improvements to existing buildings (2)

18. Energy efficiency improvements to existing buildings (3)

19. Energy efficiency improvements to existing buildings (4)  Improved operation & maintenance v Lighting retrofits v Energy Star  equipment v Employee education (modest amt so far) v In-house staff and contractors so far v Large potential savings remain

20. Importance of paying attention to both new construction and existing stock  1999 - Arlington government had 50 occupied buildings totaling 1.49 million sf, using 25.4 million kWh per year v 2003 - those same 50 buildings used 9.6% less electricity (saving 2.4 million kWh) v During 1997 and 2003, Arlington built, bought, or leased 11 buildings totaling 265,000 sf, using over 6 million kWh/yr
