Effect of occupant behavior on peak cooling and dehumidification loads in typical and high-efficiency homes

•Internal gains in higher performance homes have a larger impact on total loads.•5th, 50th, and 95th percentile internal gain profiles generated stochastically.•Latent internal gains can account for 50% of the latent load in humid climates.•Dehumidification equipment sized based on median internal loads may be undersized.
