The article discusses how energy efficient buildings can improve indoor comfort without harming health. A simulation model was created to study human comfort in an office setting. The model considered factors like insulation, solar heating, and HVAC systems. By adding a heat source and ventilation, the model evaluated indoor air temperature and human comfort. The study found that these factors can impact thermal sensation, as measured by predicted mean vote (PMV) and predicted percentage dissatisfaction (PPD) indices.
