A simulation-based assessment of technologies to reduce heat emissions from buildings

Heat emissions from buildings are part of anthropogenic heat leading to urban overheating. This paper aims assess how technologies (i.e., energy conservation measures - ECMs), used decrease use, may also reduce buildings. study employs the physics-based engine EnergyPlus simulate main components ambient air: envelope, zone, and systems. Hourly simulations run for IECC single- multi-family reference models with three representative climates: Miami, Baltimore, Chicago. The results show that performance ECMs varies among weather, seasons, residential typologies. Particularly, some cool coatings, pumps, additional insulation, energy-awareness occupants) a strong in emissions, yet they not always correlated proportional decreases use. When all combined, reductions larger on (89%) than site (65%) base cases. During summer combination shows building surface component 80% during daytime, 92% HVAC counterbalanced increase zone 88%, bringing daily total emissions. contributions this quantifying typical influence using informing planners stakeholders prioritizing mitigating overheating problems.
