Overview n n Problem Background Problem Statement n n n n n Green Buildings Site Architectural Structural Foundations HVAC/Electrical/Plumbing Budget Schedule Proposed Design Alternatives

Problem Background n Drexel has increased enrollment and student housing n Demand for: Places to eat n Additional recreational activities n Convenience stores n Study facilities n

Problem Background n Campus lacks commercial space n n n Pharmacy Restaurants Movie Theater Variety is limited Campus lacks green space Princeton Review 2007 n #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 n Certification Levels: n n n LEED Certified LEED Silver LEED Gold LEED Platinum Benefits over conventional building construction Green Roof will enhance Drexel’s green space and scenery

Site n Located at existing Myers Hall Dormitory n n n Corner of Powelton and 33 rd Streets Originally intended to be a temporary housing facility Proposed to be demolished as part of Drexel’s expansion plan

Site n 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 n Sustain load capacities of structure as if separate entities. n n Bowling alley design live load ~ 75 psf. Movie theater design live load ~ 100 psf. n IBC 2006 Section 1607

Structural n n Proposed green roof will have a design dead load varying from 40 – 100 psf. Dead load from proposed green roof depends on: Vegetation type n Soil depth n Drainage n Insulation n Waterproofing design n

Structural n Earthquake, Wind, and Snow n Philadelphia region: Seismic design exposure category “B” n Design wind speed of 90 mph n Design anticipated snow load 30 psf n n IBC 2006, Section 1613, 1608, 1609

Foundation n 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 n more cost effective susceptible to settlement IBC 2006 Section 1805 requires: n n minimum depth of 12 in. below grade minimum width of 12 in

Mechanical n Identification of Problems n n 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
