Selecting and Estimating Optimum Passive Designs of Energy Efficiency in Educational Buildings in Turkey

The consumption of energy in building sector consists about 40% of energy consumptions by words. In this investigation we analysis using the passive design in educational buildings by selecting the Technology faculty building in Selçuk university at Konya city as example of Tik-tip project .To estimate the optimum case of passive designs, firstly proposal two new educational building envelopment ( cubic building with 1:1 aspect ratio and cylindrical building) at same floor area of original existing envelopment at same façades design and more compact by less outdoor walls and then analysis to use eight passive designs (orientation , double façades, window wall ratios, court yards, green-lands and environment’s area, shading device, set temperature and building tightness) in each new envelopments by simulations each ones using Autodesk Revit 2020 and analysis optically same designs by Ecotect 2011 based on actually yearly weather data selecting it in NASA weather data web site .At the result of analysis the proposed the new envelopment’s we have more energy efficient at each one about %16.7 decreasing in cooling load and %20.76 saving of heating load in cubic building with % 19.9 saving in cylindrical envelopment and then have saving in total yearly air-conditioning load about % 19.3 and % 18.75 in cubic and cylindrical envelopment respectively. A last when used the other passive designs in optimum case we have total energy saving in air conditioning load about %33.36 in cubic envelopment and %30.9 in cylindrical envelopment when compared it with existing building envelopment of technology faculty in Selçuk University.
