My Design 2013 Long Long time ago 2015 Can i do Better? My HVAC Design 2013, my concern Summer = Winter 2015 can I do better, can return to the basics Jun 2015 Transsolar Academy 1

Individual Project Agenda • Project Selection - done • Project Analysis of „design as is“ – done • Development of Saving Strategies – done • Compliance of Strategies with Code – done • Verification of Strategies by Simulation – done • Economical Calculation of Paybacktime – done • Verify, review and generate final report - Current Work Transsolar Academy 2

Passive Power This is the work flow of Hospital (PPH) Improve the project, I start with Daylight Geometry surface Status adjustment daylight status of the reflectivity project, and in parallel make the building physics analysis, to Hybrid compare with the DIN ASHRAE and DIN Transsolar Handled Passive standards, after that, i Green Box Design continue making a proposal to change the Mechanical HVAC geometry of the Options building, to achieve the ASHRAE goals of the, DIN Hybrid Handled design.
