The TeamBackgroundAnalysis 1Analysis 2Analysis 3 Owner: Geneva Community Unit School District #304Architect: Larson and Darby GroupConstruction Manager: Bovis Lend LeaseConsultants: Rempe-Sharpe and KJWW

The SystemsBackgroundAnalysis 1Analysis 2Analysis 3 MechanicalHVAC: (2) 300 ton air cooled chillers, 6 AHUs, dust control systemHeating: 2-pipe heated water system, (2) 250 BHP boilers, individual fan coil units throughoutAdditional Heating: 2,340 linear feet of radiant ceiling panels

The SystemsBackgroundAnalysis 1Analysis 2Analysis 3 ElectricalSupply: 2732 KVA 480/277 lineMain Distribution: 4,000 A, 480/277, 3 PhaseTransformers: (2) 500 KVA, (1) 225 KVAGenerator: 250 KVA, 480/277, cross-linked to existing middle schoolFire Protection4 zone, wet systemsmoke detectors and alarms

The SystemsBackgroundAnalysis 1Analysis 2Analysis 3 StructuralUnit A/C: Single story. 12 CMU load bearing masonry on concrete strip footings

Unit B: Two story. Structural steel with combination architectural precast and face brick. Flooring is 12 hollow core precase with 3 poured slab topping. Basement utilizes step footings to match CMU coursings.

Interior Wall System, Building B

IntentBackgroundAnalysis 1Analysis 2Analysis 3 Building B Interior Wall Type

Burnished face CMUdurable, attractive, high fire ratingexpensive, heavy, coordination issuesMetal stud walllightweight, inexpensive, fewer coordination issuesless durable, thermal bridging, sound transmission

MethodsBackgroundAnalysis 1Analysis 2Analysis 3 Wall takeoffCalculate unit weight of different wall typesCalculate total weight differenceRe-size structural steel membersCalculate cost savings for steel and new wall type

Obstacles to Building Green Schools

IntentBackgroundAnalysis 1Analysis 2Analysis 3 To better understand why more schools arent being built green and find the obstacles that are allowing this to happen

Benefits: Reduced Energy BillsSmaller Environmental ImpactBetter Student Performance

MethodsBackgroundAnalysis 1Analysis 2Analysis 3 Online researchPhone interviewsMore phone interviews

The Way Schools BuildBackgroundAnalysis 1Analysis 2Analysis 3

Funding from tax dollars or referendum

Community Involvementreferendum, forum, SC had no requirementprojects were at various states or preparation

Hired Outside ArchitectsGeneva had an in-house architect

FindingsBackgroundAnalysis 1Analysis 2Analysis 3 Schools and districts generally unaware of benefits of green design. Also unaware of government green incentive programs.Architects always suggested the green designhad to do some convincingNon-Green Schoolsvarious excusesinsisted green was still on their minds

ConclusionBackgroundAnalysis 1Analysis 2Analysis 3 No green buildings without green design

Owner and community education

Government incentives
