Drexel University Student Center Group #15 Advisor: Professor Aspasia Zerva Members: Nathan Zipay Matthew Neary Brett Molash Steven Natale Courtney Dantone Overview Problem Background Problem Statement Green Buildings Site Architectural Structural Foundations HVAC/Electrical/Plumbing Budget Schedule Proposed Design Alternatives Problem Background Drexel has increased enrollment and student housing Demand for: Places to eat Additional recreational activities Convenience stores Study facilities Problem Background Campus lacks commercial space Pharmacy Restaurants Movie Theater Variety is limited Campus lacks green space Princeton Review 2007 #2 for “Campus is unsightly, tiny, or both” Green Building Buildings that are energy efficient and environmentally friendly Leadership in Energy and Environmental Design (LEED) point scale system Six categories of certification criteria Water Efficiency Energy and Atmosphere Materials and Resources Sustainable Sites Indoor Air Quality Innovation in Design Green Building Certification Levels: LEED Certified LEED Silver LEED Gold LEED Platinum Benefits over conventional building construction Green Roof will enhance Drexel’s green space and scenery Site Located at existing Myers Hall Dormitory Corner of Powelton and 33rd Streets Originally intended to be a temporary housing facility Proposed to be demolished as part of Drexel’s expansion plan Site Investigation of Myers Hall completed to see what materials could be recycled/reused Design Goals Demolish Myers Hall Construct a multi-functional student building Qualify for LEED Certification Site Expand “green” spaces on campus Green Roof beautiful area for students a view of center city more efficient building Student survey was distributed Student Poll Results Top 3 choices for fast food: Wendy’s Q’doba Panera Bread Top 3 choices for sit-down restaurant: TGI Friday’s Applebee’s Ruby Tuesday Top 3 choices for activities: Movie Theatre Bowling Alley Outdoor Basketball Architectural Must blend with adjacent building facings Material options for facade Light brick Copper facing Building must meld with community No more than 3 stories tall Views Shadows Foundations Architectural Program Type of space Occupancy expectations Volume of occupancy Proximity to other spaces Structural Sustain load capacities of structure as if separate entities. Bowling alley design live load ~ 75 psf. Movie theater design live load ~ 100 psf. IBC 2006 Section 1607 Structural Proposed green roof will have a design dead load varying from 40 – 100 psf. Dead load from proposed green roof depends on: Vegetation type Soil depth Drainage Insulation Waterproofing design Structural Earthquake, Wind, and Snow Philadelphia region: Seismic design exposure category “B” Design wind speed of 90 mph Design anticipated snow load 30 psf IBC 2006, Section 1613, 1608, 1609 Foundation Foundation will need to support the above structure and transmit loads to underlying soil Deep pile foundations not common for low rise buildings in Philadelphia area depending on a soil investigation. Anticipate a shallow foundation more cost effective susceptible to settlement IBC 2006 Section 1805 requires: minimum depth of 12 in. below grade minimum width of 12 in Mechanical Identification of Problems Need for efficiency in energy and cost Multi-use building is unique Comfort Levels of individuals LEED standards Winter Interior DB 75 Degrees F Heating Degree Days 4486 DD Winter Interior RH <60% Percent Winter Exterior DB 10 Degrees F Summer Interior DB 75 Degrees F Summer Interior RH <60% Percent Summer Exterior DB 93 Degrees F Summer Exterior WB 78 Degrees F Summer DR from DB 19 Degrees F CFM per Occupant 20 CFM Mechanical Mechanical (Electrical) Proper design can reduce energy consumption by 50%!
