The Office for Mathematics, Science, and Technology Education in the College of Education hosted Morgan Johnston as a guest speaker on February 27.  One part of the overall Climate Action Plan is to increase the use of renewable energy generation for our campus power requirements. This presentation reviewed the progress toward increased use of renewables for our campus, and discussed current efforts underway, including the forthcoming Solar Farm.

The second idea we wanted to pursue was putting on the TS 101 courses.  The normal cost that Cynthia charges is $65 per person.  We thought we could contract with CCB $400 or $500 to do a full day lunch provided TS101 training for 10-15 people.  It would be offered to students and staff who wanted to learn more about safety and promised to be a safety advocate.  This would save money over the total cost of training and allow a larger group of folks receive serious safety training. - James Roedl
 

The existing structure was assessed based on the original 1966 drawings prepared by Lev Zetlin and Associates (see Appendix A). The current roof structure consists of a 6 in. reinforced concrete slab supported by steel trusses that span 84 ft across the Great Hall. The trusses are made up of teeshaped chord members and double-angle web members. Secondary wide flange beams spaced at approximately 21 ft span between the trusses and create two-way action in the slab. Analyses conducted during Phase 1 of this Feasibility Study showed that the secondary components (roof slab and beams) do not have sufficient capacity to support the added load of the photovoltaic array. Consequently, support systems were conceptualized that would deliver the new loads directly to the trusses. Analyses conducted during Phase 2 therefore focused on the roof trusses.

Loads and stresses on the trusses were determined using the American Society of Civil Engineers (ASCE) 7-10 design loads and typical material weights. Taking into consideration the dead loads (truss members, roofing materials, concrete slab, catwalks, and ceilings) and snow loads, the total load on the roof structure is estimated to be 130 lbs per sq. ft (see table below). With a distance of 21 ft-4 in. between trusses, this equates to approximately 2,800 lbs per lineal foot applied to the truss.

• Existing Load Summary - Load (lb/ft2)
• Truss (Self)                                     10
• Slab                                                   75
• Catwalks and Ceilings                   13
• EPDM Roof                                       5
• Insulation                                          3
• Live Loads (Snow)                         25
• Total                                                131 lb/ft2

Using structural analysis software and hand calculations, it was determined that the members of the existing roof trusses labeled T-3 in the original drawings do not meet the current structural steel code for compression capacity under these load conditions. At the time of original construction, the members met requirements called for by the applicable code, the American Institute of Steel Construction (AISC) 6th Edition Steel Construction Manual. The AISC Steel Construction Manual has since been updated to account for torsional and flexural-torsional buckling and strength limitations of slender elements within members.

The trusses were also analyzed for the addition of the PV cells and accompanying concrete knee walls. The weights of these materials and associated snow drifting loads would apply an additional 30 lbs per sq. ft (see table below), or approximately 665 lbs per lin. ft to the T-3 trusses at the locations of the new walls.

• Additional Load Summary - Load (lb/ft2)
• Concrete Wall                                    18.75
• Photovoltaic Cells                               5
• Snow Drift                                            7        
• Total                                                    31 lb/ft2

These loads would introduce an additional sixty thousand pounds (approximate) into each of the steel chord members, causing four additional chord members to be stressed beyond code-prescribed limitations

F&S Garage and Car Pool had provided IBI with a truck that could be used for moving waste vegetable oil as well as biodiesel.

Unfortunately the truck that was used has been transferred to another department. At this time I am not aware of any other suitable truck becoming available. The University's fiscal situation is such that it is highly unlikely that another truck will be available in the near term.

Collection and transportation of the biodiesel requires tanks and pumps. The size can vary depending on scale, but the equipment is needed regardless for efficiency. 

Morgan Johnston spoke with Mike Brunk with the City of Urbana about the Arbor Day Celebrations held by the City of Urbana in previous years. 

• The tree planted on the west side of Follenger Hall was for the tenth anniversary of Urbana’s Tree City designation in 1986.
• Urbana does a proclamation that the Mayor reads, usually signed by the Mayor of Urbana and the Mayor of Champaign. Urbana facilitates it,and they could add UI.
• They work with the park district, and build trees in the parks, invite a particular school with one or two grades.  They pre-plant the trees and have mulch piles, so the kids get to mulch the tree. Talk about the eco benefits of trees with a barrel of water and a five gallon bucket and a milk jug. 
• It is actually bird and tree day.  Entertain the kids, proclamation from mayors, newspaper, and event for kids.  Tree planting of some sort and an acknowledgement.

Evan De Lucia and Allan Stratman agreed to fund Nishant Makhijani for the Spring [2015] semester and allocate $750k to the RLF Program.
