Assessing Building Arcteristic

Ini termasuk itu Size, orientation levels, window typets, and companpanpy pattes paction helps in n estimating internal and extergains.

Kalkulating External Loads

External loads are influenced by outdoir weatherr conditions and building features. To kalkulate these, conitider factors such as a s:

  • Solar radiation through windows and walls
  • Heat transfer through walls, roof, and windows
  • Ventilation and infiltration air exchange

Using local clamate data, you can estimate te heat gain or loss for each component, which concontributes to te overall hadd.

Kalkulating Internul Loads

Internal loades compe consupants, liling, propercitages, and equipment. To estimate these, conitider:

  • Number of convapants and their actiity levels
  • Lighting powir density
  • Equipment and appeance heat output

Summing these internal heat gains provides thee totul internal had, which ik added to external loats for total systemm rementations.
