Commissioning <br />1 What is commissioning? <br />^ Systematic process of ensuring performance of all building <br />systems <br />o Fundamental Commissioning is a LEED prerequisite <br />o For new construction, median commissioning costs were <br />$1.00/kz (0.6% of total construction costs) yielding a <br />median payback time of 4.8 years <br />°We find that commissioning is one of the most cost-effective <br />means of Improving energy efficiency in commercial <br />buildings.° <br />so~,roe~. ~e~, zooa <br />Costs of Green Building <br />^ "No significant difference in average costs for <br />green buildings as compared to non-green <br />buildings." <br />o "Many project teams are building green buildings <br />with little or no added cost, and with budgets well <br />within the cost range of non-green buildings with <br />similar programs." <br />Sowce: Coat of Green Reviaked, Davis Langdon, 2°07 <br />Capitol Area East End, Block 225 <br />Costs of Green Building <br />^ "Cost of green buildings tend to <br />decline with experience in design and <br />development..." <br />^ "An upfront investment of less than <br />two percent of construction costs <br />yields life cycle savings of over ten <br />times the initial investment." <br />sue, <br />Ther°oafa snd Flrwnclal Berrorlla of Green Bulldlme Grey Katz, alai. <br />w.vv. cMn~b, ce.pov/graenbulldirg/DesigNCosllssues, hUrJICOCt&Baneflt <br />Lessons Learned <br />^ Teams experienced with LEED have lower <br />additional soft costs; some teams can do <br />LEED documentation with very little <br />additional cost <br />^ Prequalifying contractors for LEED helps <br />keep costs down significantly <br />^ Smaller projects (e.g. <10,000 sq. ft., <br /><$3million) burden higher costs <br />proportionally <br />Pleasanton Fire Station <br />3 <br />^ LEED Gold <br />^ 8,500 sf <br />^ 75% C&D diversion <br />^ Bay-Friendly landscape <br />^ PV system <br />^ LEED ~ 2.0 Gold <br />^ 1.4 million sf Offices & Parking <br />^ Executive Order now requires LEED Silver <br />
