  Us­ing vari­ous ex­amples from the Bahn­stadt Heidel­berg, we show how we pro­ceed with air­tight­ness meas­ure­ments in lar­ger build­ings, in which dif­fi­cult meas­ur­ing con­di­tions some­times oc­cur, as well as how we deal with them and why air­tight­ness meas­ure­ments in Pass­ive Houses in­cur lower costs than in oth­er build­ings. Over the past 25 years, we have seen sig­ni­fic­ant de­vel­op­ments in the air seal­ing of build­ings. Vari­ous meas­ure­ment meth­ods are shown which provide an ad­equate check of the real­ized build­ing air­tight­ness.

  The Bahn­stadt dis­trict in Heidel­berg is cur­rently the site of the largest Pass­ive House set­tle­ment in the world. However, have the ef­forts made by the city of Heidel­berg to en­sure qual­ity paid off? KliBA has evaluated the values for district heating and electricity demand for 14 residential building plots with a total of around 2,300 residential units. The conclusion: Together with the new wood-fired combined heat and power plant, 95% CO2 reduction will be achieved. A close look at the heat flow shows that the heating energy is mostly in the target corridor and that the building envelope is unproblematic. Three construction sites are currently being analysed in more detail.
