Apstrakt

Regulacija izvora zagađenja unutrašnjeg vazduha i ventilacija, sredstva su za poboljšanje kvaliteta unutrašnjeg vazduha. Nedavno su tri nezavisna eksperimenta potvrdila da uklanjanje izvora zagađenja ili povećanje broja izmena vazduha ventilacije poboljšavaju osećaj kvaliteta vazduha, smanjuju jačinu nekoliko simptoma sindroma bolesne zgrade (SBZ) i poboljšavaju produktivnost kancelarijskog službenika. U ovim eksperimentima, izvođenje simulacije kancelarijskog rada (kucanje na mašini, sabiranje, korekturni posao – ” tipični kancelarijski poslovi koji zahtevaju koncentraciju) poboljšavalo se jednomerno, kako se broj osoba nezadovoljnih kvalitetom vazduha smanjivao sa svakim merenjem. Kvantitativan odnos je bio 1,1% promena u aktivnosti na 10% nezadovoljnih, u opsegu 25 – 70% nezadovoljnih, ili 0,5 % promena u delanju na 1 decipol (dp) u opsegu od 2 do 13 dp. Značajna poboljšanja u aktivnosti desila su se samo kada je intenzitet opštih simptoma SBZ, kao što su glavobolja i teškoće u jasnom rasuđivanju, znatno smanjen, što je značilo  daje u pitanju uzročni mehanizam. Izvođenje simuliranog kancelarijskog rada povećavalo se jednomerno sa smanjenjem opterećenosti zagađenjem za 1,6% povećanja u aktivnosti za svako dvostruko smanjenje zagađenja u opsegu od 0,3 do 2 olf/m2 poda i sa povećanjem dovođenja spoljnjeg vazduha po stopi od 1,8% povećanja u aktivnosti za svako dvostruko povećanje stope dovođenja spoljnjeg vazduha u opsegu od 0,8 do 5,3 L/s po olfu. Pošto  ovi rezultati jasno opravdavaju povećane inicijalne i pogonske troškove, budući razvoj tehnologije KGH može uključiti "personalizovani vazduh – ,  nove puteve poboljšanja kvaliteta dovodnog vazduha (npr. filtracijom), ekstenzivniju primenu rekuperacije toplote iz otpadnog vazduha i sistematsku selekciju malozagađujućeg materijala za građenje i proizvodnju nameštaja.
