CONSCIENTIOUS LIFE What is a Passive House? A passive house is one built within a particular set of design principles. These principles attain a quantifiable level of energy efficiency and specific levels of comfort. According to the Passive House Institute US (PHIUS) the following are the five principles that guide the development and construction of a Passive House: 1. Continuous insulation through the entire envelope (exterior) of the house without any thermal bridging (heat transfer) 2. Building envelope is extremely airtight preventing air transfer 3. Employs high-performance windows and doors 4. Utilizes some form of balanced heat and moisture recovery ventilation (allows the home to ‘breathe’) with minimal heating and cooling systems 5. Solar gain (heat from the sun) is managed to exploit the sun’s energy for heating purposes and minimizes the sun’s impact during the cooling seasons The concepts that make Passive House systems unique are not new. Developed in the 1970’s as a response to the OPEC oil embargo, passive house building standards seek to cut carbon emissions and greatly reduce energy consumption. It has taken over 30 years for this building system to make its way to Indiana despite the fact that some of the research into superinsulation happened just over the Illinois border at the University of Illinois at Urbana-Champaign. Indiana’s First Passive House In the summer of 2015 Indiana’s first certified Passive House was completed. Builder Dan Porzel of Cedar Street Builders created Project 580 in Zionsville, Indiana. It is one of only 125 homes to meet the Pa ]H\Hܚ]KBSPSH SHPQVSHTQHBXH[H[]Y]\ˈ\]X\BX\و[\YۈX[YY\]ܞ[\YۈHX]]Y[ 8'[\\Z\x'H[HYH]\ ]X\HY]XݙHܛ[ ]\Y\[[H[]ˈ]8&\™[\HYXY[\YX][ۜ\HX[NQQ܈Y\[\H\TH[܈Z\\H\[\HXYB[\]H\H[]]H\YYY ڙX N X]\\‚(H[[]Yۘܙ]HܛH[][ۂ(H[XYHوX\[[[]Y[[‚(HY \\ܛX[H\x(B(B(B(B(B[H[’P\[HL HX[\[Y][ۘ[[[XX ]\[\[Y\[H[\\[B\]HZ[[B[X[X][X] M [X[[[\ L\YۙYX^[Z^H]\\X]H[][ۈوڙX N \Z[و[[]Yۘܙ]Hܛ\ˈH[[HوHYH\XYHH L'BXX\[[[]Y[[ T B]]H[[[][ۈ][YHو L\\H][]\YHXXZ[YH\HH[\H[[]Y]H][YH L MK ][YH\HYX\\Bو\X[\\[H\Y[Z[[ˊBHو\[XYHوYXX]YT[[]\H\YۙYX\HY][ۈو\[[[H]\KH\]KX\YYY[\BHY \\ܛX[H\K\[H\][[\ZYH[HZ\›وHYK]XHYHX[YYHۙHX^BY[ۙ\\HYB'X]O'HH[\HXݙ\H[[]܈\H][ۈ\؛[K][[ۜY\Z\[ݚ[[[]وHYH]HX\[[[و[\H[ٙ\\XKܙX][][[\\]\\[H][[\ۛY[ [Y][ۈ\\[H[\ݙ\Z\]X[]H\^[ۙ۝[[ۘ[Pœ\[\ˈ\[H\H\]HۂB
