2021 Pas­si­ve Hou­se Award – Spe­cial award


SI­GA "Air­tight­ness" Award

Around 50 % of the en­ergy used world­wide is con­sumed in build­ings. Most of this en­ergy is used for heat­ing and cool­ing. An air­tight build­ing en­vel­ope can re­duce en­ergy con­sump­tion and, as a res­ult, sig­ni­fic­antly re­duce cli­mate-dam­aging CO2 emis­sions. Such a build­ing en­vel­ope also sig­ni­fic­antly im­proves liv­ing com­fort while pre­vent­ing dam­age to the build­ing and ex­tend­ing its ser­vice life.

The SIGA Air­tight­ness Award is presen­ted to a build­ing that is dis­tin­guished by an out­stand­ing air­tight­ness concept in plan­ning and ex­e­cu­tion.

The ev­al­u­ation cri­ter­ia in­clude the fol­low­ing points:

  • Im­ple­ment­a­tion (as­sessed by meas­ured air ex­change rate and con­struc­tion site doc­u­ment­a­tion)
  • Air­tight­ness concept & air­tight­ness design (as­sessed by tex­tu­al de­scrip­tion and plan de­tails)
  • Longev­ity (as­sessed by tex­tu­al de­scrip­tion, pho­tos, de­tailed draw­ings and pos­sibly re­peated air­tight­ness test for older build­ings)




SIGA is an in­ter­na­tion­ally act­ive Swiss fam­ily busi­ness and is a lead­er in the de­vel­op­ment, man­u­fac­ture and sale of high-per­form­ance ad­hes­ive tapes and mem­branes for wa­ter­tight build­ing en­vel­opes. SIGA's vis­ion is a world in which build­ings do not waste en­ergy. SIGA has there­fore de­ve­loped a com­pre­hens­ive range for in­door and out­door ap­plic­a­tions and for a wide vari­ety of build­ing situ­ations.
SIGA pro­duces in Switzer­land. Sales are or­gan­ized via world­wide loc­a­tions in Cent­ral and North­ern Europe, China and North Amer­ica. SIGA op­er­ates in 25 coun­tries and em­ploys over 500 people.
