The video tutorial discusses the effects of internal heat gain on building temperature. Initially, it assumes no internal heat generation, but later considers the impact of heat from occupants and appliances. The tutorial explains how internal heat affects steady state temperature and introduces an exponential equation to calculate temperature changes. The final equation accounts for internal heat gain, providing a comprehensive understanding of temperature dynamics in buildings.
