materials
Requirements• Use materials with recycled content such that the sum of post-consumer
recycled content plus one-half of the pre-consumer content constitutes at least 10% f MR 4 1 20% f MR 4 210% for MRc4.1 or 20% for MRc4.2

Minimum Performance Requirements
• Must comply with environmental laws
• Must be a complete permanent building or space• Must be a complete, permanent building or space
• Must use a reasonable site boundary
• Must comply with minimum floor area requirements (NC, CS, School, EB:OM 1000sf/)(CI 250sf)
• Must comply with minimum occupancy rates (if less than 1 fte no IEQ points are awarded but the prereq must still be adhered to)
• Must commit to sharing whole building energy and water usage data
• Must Comply with a minimum building area to site area ratio (building no less than 2% of gross land area) ( g g )
LEED Process
• Register the project - $1200g p j
• Project Administrator invites project team to join LEED OnlineOnline
• Project Team are assigned points/ credits that they are responsible forresponsible for
Design Stage Submittal
Design Stage Submittal
• Design Team complete all design point templates being g p g p p gpursued
• Client/ Owner/ Developer – completes MinimumClient/ Owner/ Developer completes Minimum Performance Requirement details
Design Stage Submittal issued to USGBC/ GBCI• Design Stage Submittal issued to USGBC/ GBCI
• USGBC / GBCI review takes about 8 weeks, points are defined as “anticipated” or “rejected”
• Credit clarification for “rejected” pointsj p
• Option to do combined design and construction submittal
Construction Stage Submittal
• Construction Team invited to join LEED Online toolj
• Contractor completes all relevant templates
Construction Stage Submittal
• Design Team provides confirmation that the project has not g p p jaltered since the design stage and that design templates are still correct – credit clarifications
• Construction Stage Submittal issued to USGBC/ GBCI
USGBC / GBCI review takes about 8 weeks points are• USGBC / GBCI review takes about 8 weeks, points are defined as “approved” or “rejected”
• Credit clarification for “rejected” points – team allowed 1 month
• Resubmission to USGBC for final review – Credit appeal process if necessary
