ofElectrical Smart Grid Technology Solutions Retrofitting the Soldier Eield Parking Structure Overall Project Summary IPRO 338 revolves around the technoVeconomic analysis of a preexisting structure (in this case a parking garage) and proposing ideas that could be used in order to make said structure more energy efficient and sustainable This IPRO is also taking part in this year’s NECA Green Energy challenge lts goals are similar to the IPRO program, but teams from across the nation from several top schools compete in order to come up with the most innovative and energy efficient solutions for their respected sites The site for our teams audit is the parking structure for the chicago Bears home field, Solider Field In addition to the Bears games, this field hosts events almost daily, ranging from weddings, soccer games, mega concerts and more This parking lot is also the heart of chicagos historical Museum Campus, which is home to the Shedd Aquarium and Field Museum The structure is built underground and hosts4 levels With space for 2,500 cars The roofoftheparkinglotisthesecondlargestgreen roof in chicago The site provides a unique challenge because Solider Field, including the parking lot, is the first LEED certified football stadium in the NFL The site selection for our audit provided a unique challenge to provide neW efificient technologies in a high trafific and already highly efificient structure The proposed retrofits have the potential to provide a huge impact on energy usage for a site that services a large amount ofthe chicago population This iconic campus will benefit highly from our detailed research and proposal (which will be summarized here) Lighting Retrofit During our investigation of the existing lighting system, We unfortunatelywere notable to trackdown themodelnumbers This prevented us from being able to look up the manufacturers specifications that could tell us the inputwattages for each existing fixture We knowthattheinputwattages forlighting fixtures are almost alwayshigher or loWer than thesum ofthe bulb wattages However, for the purpose of our analysis we made the assumption that the existing fixture wattages are equal to the sum of their bulb wattages Thus, after examining the existing lighting system for the garage we concluded that the total saving in energy cost would be around 55% of the original amount if LED light fixtures are implemented (see Lighting Retrofit Graph) Solar Retrofit We proposed that an elevated solar panel structure be placed on the two ventilation exhaust areas located on the east and west sides ofthe garage The system will connect directly to the grid for Soldier Field and the garage, so no batteries will be needed We found the system to be economically viable ifstate and federal rebates and grants can be taken advantage ofto the fullest extent The system will have the added benefits ofimproving the garages public image and giving thesite more LEED points, possibly leading to an increased LEED rating EV charging Station Retrofit The management team ofthe North Garage at the museum campus in chicago has made great efforts in creating and maintaining an ecologically friendly and energy efificient structure To this end, three electrical vehicles charging stations have been installed in the north garage only for visitors attending events at Soldier Eield andsurrounding museums Our project plan was to analyze the existingconditionsofthe chargingstations and propose improvements as necessary in order to increase the garages energy efificiency In turn, this has led us to the conclusion that a new EV charging station will raise the overall uptime of the charging system (see EV graph for a comparison against gas powered vehicles) Thermal Retrofit The thermal team was dedicated to improving the efificiency of the HVAC system in the Soldier Field North Parking Garage The parking garage is a multirtiered underground structure composed of precast concrete sections Due to the nature ofthis construction and placement, the opportunity for natural ventilation Was nonrexistent, necessitating the use of a forced air system The HVAC system does not provide any space conditioning, as its only duty is to provide fresh air to the parking garage, and remove the air contaminated with vehicle exhaust Our team concluded that the best courseofaction wouldbeto install variable frequency drives, which would control the flow of the system more efificiently (rather than an always on or always off system, see Thermal Retrofit graph) IPRO Day 0 u r presentation and exhibit at this years IPRO day Won us top honors within our respected track (TrackZ Energy and Sustainability) and it is our hope to place within the top three

MATTISCANNELL ae@technewsll com Flash Game Review: ‘Alice is Dead’ Kristal Copeland con EDITOR Alice is Dead is a series of three points andrclicki escapertherroom, horror/mystery flash games available to play on sites like Newgrounds The inspiration and follow through gives you this darker take on Alice In Wonderland “You’ve arrived in Wonderland, thats good Alice is dead, thats bad You don’t know who you are, thats the worst” When the game starts, your first scene is Alice lying dead under the rabbit hole You have to find clues to figure out exactly what happenedwherethe [silent] maincharacterhas amnesia This game is not particularly difificult to figure out but there are many walkthroughs available online This game has a wonderful ambiance and a sinister tone that continues through the game even past the plot twist at the end Ilovea goodtwistl My favorite thing about this gamewat least the first~ is that almost every single thing matters There are plenty of areas that seem like emptyspaces, but you’ll soon find that even the walls talk Graphics 9/10 the graphics are extremely well done, I could imagine playing this as a computer game offa DVD There is a constant grainy look that adds to the mysterious feel of the game, and the arrows that take you left and right are shaped like hearts or spades, and the characters are drawn in away that brings out the more sinister tone of this series I believe this game has the best art ofany flash game I have played so far, even ifit isn’t in my favoritestyle Game Play 7/10 Well, I gave it a 7 because its only clicking, butyouwill probably disagree ifyou like these games,so definitely go ahead if youemoythem lntermsofgameplayelements, there are the standard item combinations and different, not necessarily obvious uses for things I have played many point and click games, sol probably saw a few more things coming than I should have Either way, its well done enough Flash Game Review: ‘Relive Your Life' Kristal Copeland to earn 7 even ifthere aren’t any timed or skill testingsections Story 8/10 This is a mixed bag A lot of people were unsatisfied with the ultimate conclusion ofthis game, including me They left a lot of information up to the players imagination, and there is a question everyone asked from the very first game that was not ever answered The ending was also very abrupt, which many did not emoy I agreed with the creater in this respect, the world of the game is prone to abrupt endings, to end another way might actually have felt odd Lastly, the author saysheis goingtoWriteasortofminirWiki about the questions that were unanswered, so there is that, ifyou thinkit is worth it Sound 8/10 There are no huge musical scores in this game Thereseems to be one or two insanely creepy tracks per game that followyou around In the first, there is a slightlyrtothappy “Hush hush hush, here comes the boogyman” song that gets louder as you approach a certain area The sound add dramatically to the atmosphere ofthe game, so even though I didn’t thinkthe musicitselfwas great, I gave thisan a Heyl That rhymes Trophies and everything else Trophies are available in some ofthe games and may or may not be extremely difficult to figure out or achieve (one is purely luck based), getting all ofthem ensures thatyou have had experienced everything the game has to offer, which I think is a great way to do trophies There are a few Easter eggs in this game, for the most part, ifyou thinkitsoddthatsomethingisin theroomWith you, you should try doing things to it, however, nearer to the end ,some thingsarenotexplored I think this series is worth playing ifyou emoy Alice in Wonderland with a twist, dark themes, escape the room games or point and click games lfyou don’t like endings that don’t wrapeverything into a nice package, you might Want to steer clear, or better yet, only play the first game Have fun guysl l E El!
