Goals

• Projects with >$10M construction value (non-clinical)– LEED v2009 Silver certification– ASHRAE 90.1 2007 plus 30%

• Clinical projects with >$10M construction value – waiting on LEED v2009 standard

• Projects with <$10M construction value – UM Green Design Guidelines

SID-D Energy and Water Conservation

• All Projects must– Comply with ASHRAE 90.1 2007– Mandatory ECMs listed– Evaluate potential ECMs listed– Water conservation measures listed

• $2M-$10M– DOE COMcheck software to demonstrate compliance– Document impact of ECMs incorporated

• >$10M– 30% beyond ASHRAE 90.1 2007– DOE COMcheck software to demonstrate compliance– ASHRAE 90.1 computer energy simulation for baseline consumption– Document impact of ECMs incorporated– Provide an Energy Impact Statement

• Payback periods– SL 15yrs use 6 yr– SL over 20 yrs use 8 yr– Fenestration and glazing use 10 yr– Membrane roof insulation use 12 yr– All other insulation use 30 yr

SID-K Sustainable Design and LEED

• Prior to SD clarify sustainable design objectives

• Projects in existing LEED buildings cannot jeopardize LEED certification

• Non-clinical over $10M achieve LEED Silver certification unless waived by Executive Sustainability Council

• Baseline LEED checklist created
