[1016] Architecture: Designing Wrightwood Crossing


Published on

At the Chicago Center for Green Technology for a presentation [1016] Architecture presented this discussion about the LEED-registered "Wrightwood Crossing" project currently under construction in Lincoln Park, Chicago.

This presentation touches on sustainable design ideas through the lens of this multi-family case-study, including: practical application of the LEED for Homes rating system, advantages of infill development, and specific systems used on the project to reach the Platinum design rating goal.

  11. 11. Where did we start? <ul><li>Identify inherent advantages </li></ul><ul><ul><li>Building site was infill development </li></ul></ul><ul><ul><li>Finish level was set to be high </li></ul></ul><ul><ul><li>Client was willing and informed of LEED process and benefits </li></ul></ul><ul><ul><li>Client was also acting as General Contractor </li></ul></ul><ul><ul><li>Design team was fully assembled early </li></ul></ul><ul><li>1 st Step: Figure Yes/No/Maybe points (Project scored high silver on first pass) </li></ul>

  17. 17. Lessons Learned <ul><li>Fancy, expensive systems not required to reach Platinum </li></ul><ul><ul><li>Geo-thermal was originally explored </li></ul></ul><ul><ul><li>Site-generated power was ruled out early </li></ul></ul>
  18. 18.
