For the apartment presented in the attached document. Knowing that the weather conditions in the

winter are $12C,$ and $50\%RH,$ and that the temperature inside is maintained at $24C$ and $50\%RH,$

calculate:

a$)$ Amount of sensible$,$ latent and total heat gain needed to heat the air in $k\frac{J}{k}g$ of air

b$)$ The total heat loss $Q$ through the building envelope and through infiltration knowing that

the building has medium tightness

c$)$ If the single glazed windows were replaced with double glazing with uncoated $\frac{1}{8}$ in$.$

clear pane, what is the percentage of heat loss savings that the building would experience

compared to part $($b$)$

d$)$ Knowing that this building is in a highly humid climate, describe what the architect can

do to in terms of passive approaches to minimize the effect of such conditions

Make any assumptions you may need and give your justification.
