Simulation output for typological solution sets for a hot humid climate Architecturally, the hot and humid region is one of the hardest climates to ameliorate through design. This is due to the high humidity and daytime temperatures that result in high indoor temperatures exceeding the ASHRAE summertime comfort upper limit of 26Β°C for most of the year. A cost-effective design for a hot and humid climate is one that uses the least amount of energy without sacrificing comfort. Performance indicator I Data for performance indicator I are as follows: β’ β’ β’
days of discomfort for a detached house = 300β365 days per year; days of discomfort for a row house = 300β365 days per year; days of discomfort for a multi-family apartment house = 300β365 days per year.
Performance indicator II Data for performance indicator II are as follows: β’ β’ β’
predicted energy consumption for a detached house = 3600β6000kWh per year; predicted energy consumption for a row house = 3000β5000kWh per year; predicted energy consumption for a multi-family apartment house = 2500β5000kWh per year.
