Samenvatting COMFORT EN HUID



LES 1
1. Bereken het jaarlijks energieverbruik van …

Form :
(Aantal uren per dag x aantal dagen gebruik x vermogen toestel in Watt ) / 1000 = aantal kWh



Voorbeeld : wekkerradio staat steeds aan
24 uur
365 dagen
10 Watt (terug te vinden op technische fiche)
-->jaarlijks energieverbruik : (24u x 365 dagen x 10 Watt) / 1000 = 87,6 kWh


Mens : 80 – 100 Watt
Verwarming : 1000 Watt

2. Verschil tussen waterdicht en dampdicht
Vocht = hoofdoorzaak v bouwschade
->bouwfysisch verkeerd opgezette constructies = oorzaak moeilijkheden

Schade : lijmhydrolyse bij spaanplaten
Blaasvorming bij bitumineuze dakbedekking
>>Kan ook onzichtbaar :
Afname thermische eigenschappen
Vermindering sterkte eigenschappen

Constructie dampdicht =>strengere voorwaarden dan waterdicht
Watermolecule zijn in gasvormige toestand kleiner dan vloeibare toestand

 Gasvormige watermoleculen verplaatsen makkelijker (in constructie) dan
watermoleculen in vloeibare toestand

waterdichte constructie > niet dampdicht (per definitie)
dampdichte constructie > wel waterdicht
-->gebouw moet water én damp dicht zijn



*Enkel poreuze materialen (met open poriën) kunnen binnen id massa vochtig worden

*Niet-poreuze materialen (glas, metaal,..) + poreuze materialen gesloten poriën (cellenglas) kunnen NIET id massa
vochtig worden
Hoogstens oppervlakkig nat
