1 Green Building Standards Harvard University Nvember 2009 Apprved Nvember 20, 2009 Frmatting Updates September 30, 2011

2 The Harvard Green Building Standards apply t all capital prjects. The Standards identify the minimum levels f requirements apprpriate t any prject. As always, it is up t every prject team t ensure the level f effrt is sufficient t meet the prject s needs. The Standards include six categries f requirements based n fur prject types: Integrated Design: In rder t assist prject teams in the vetting and setting f sustainability gals and bjectives Harvard has identified different levels f frmal integrated design requirements fr prjects depending n their scpe f wrk. Life Cycle Csting: In rder t assist prject teams assess the ttal cst f wnership impacts that decisins have thrughut the curse f design, Harvard has identified varius levels f Life Cycle Cst (LCC) analysis fr prjects depending n their scpe f wrk. Respnsible Life Cycle Csting includes an analysis f utility rebates, grants, stimulus funding, r ther alternative funding surces. It is best practice t include building peratins staff in all LCC and value engineering review. Energy Mdeling/GHG Calculatins: In rder t assist prject teams in creating energy efficient designs that yield reduced r zer greenhuse gas emissins Harvard has identified different levels f building energy simulatin apprpriate fr prjects depending n their scpe f wrk. Metering/Sub-Metering: In rder t facilitate efficient building peratins, assist with energy cnservatin measure verificatin, and t allw engagement f building ccupants, Harvard has identified varius levels Metering and Sub Metering fr prjects depending n their scpe f wrk. These requirements are based n the premise that ne can t reduce what they can t measure. LEED Certificatin and Harvard Specific Credits Harvard requires prjects t achieve prescriptive levels f envirnmental perfrmance accrding t prject size and scpe. New cnstructin and majr renvatin prjects are required t register and get certified using the US Green Building Cuncil s (USGBC) Leadership in Energy and Envirnmental Design (LEED ) green building certificatin rating systems. All prjects are encuraged t pursue aggressive levels f energy efficiency and sustainable design using recgnized perfrmance standards as design minimums. Clse-Out Dcumentatin/O&M Readiness: In rder t capture critical prject data and prepare prjects fr ptimal peratinal excellence, Harvard has identified varius levels f Clseut Dcumentatin / Operatins and Maintenance Readiness fr prjects.

3 Tier 1 - Whle Buildings: New Buildings and Building- Wide Gut Renvatins Integrated Design: At least three integrated design charettes, the first f which shuld happen at the time f prject kickff, which include identificatin and tracking f prject gals and analyzing the life cycle cst impacts f ptential design ptins. Charettes shuld include representatin f majr stakehlders including ccupants and peratins staff. Life Cycle Csting: Life Cycle Csting (LCC) will be perfrmed t quantify the 20 year impacts n GHG, energy csts, maintenance csts, etc. The scpe f LCC will vary depending n prject, but will typically include envelpe, HVAC, electrical, and many ther building systems. Requirements by design phase include: Planning/Cnceptual Design: Initial LCC templates with supprting narratives fr ptinal design elements with majr budget implicatins Schematic Design: LCC templates presenting ptins fr majr energy cnsuming systems Value Engineering (Any Phase): LCC templates presenting impacts beynd initial capital utlay Energy Mdeling: Utilize an hur-by-hur building simulatin sftware (equest r Energy Plus are preferred) t mdel prpsed building designs, assist with life cycle csting, estimate greenhuse gas (GHG) emissins, and facilitate future measurement and verificatin. At a minimum, the fllwing deliverables are required: Cnceptual Design: Energy mdeling isn t always apprpriate in this phase, but may be necessary t supprt majr design decisins. Energy mdeling during cnceptual design is especially imprtant fr new cnstructin prjects. Schematic Design: Initial mdel results with sensitivity analysis Design Develpment: Multiple parametric runs cmparing ptins Cnstructin Dcuments: Cmplete design and base case mdels Building Turnver: As-built energy mdel & electrnic files (Required as part f dcument turnver t PIRC. Metering and Sub-Metering: Fllw the applicable sectins f the Harvard Engineering and Utilities metering and service guidelines dcument Infrmatin & Requirements fr Utility Services. Separately meter all utilities cming int the building. When apprpriate t prject scpe, separately sub-meter significant use types within the building including. At a minimum, separately meter: Parking Garages Cmmercial Spaces Large Kitchens Data Centers r Large Data Clsets Harvard encurages separately metering utilities by end use, such as separating lighting lads frm plug lads. If this level sub-metering is nt part f the prject scpe, teams are encuraged t wire / pipe the building in such a way that sub-metering may be utilized at a later date t help identify utility demand and cnsumptin by end use. Meters and sub-meters must be tied int the building management system when ne exists. 3
