“…The occupants' responses on the sensation during the field surveys revealed that some of the residents feel "warm" or "hot" in summer. The result on the sensation aligns with the findings from existing research on occupants' sensation in buildings [8,28]. The percentage of the respondents that feel warm in the current study is significantly less than the percentage of the residents that feel warm in previous research [8,11].…”

“…The investigation revealed that more than 99% of the data gathered during the field surveys point that a rise in WBGT values leads to an increase in SSI values. The findings also highlighted that higher heat thermal indices are noted in this investigation than existing research [28]. The study considered correlations between the mean thermal indices and actual thermal sensation-TSV (Figures 8 and 9).…”

“…The research techniques include physical measurements of environmental variables (such as temperature, relative humidity, dew point, and air velocity), comfort surveys of the residents as the research approaches. Some of the existing investigations in the field of thermal comfort have utilized the research techniques considered in the current study [8,9,12,28]. The environmental variables were recorded at every 60 min using HOBO sensors placed on the internal walls at 1.7 m above the floor.…”

“…Concerning the computation of thermal indices, existing research has outlined different models for calculating thermal indices in various thermal environments [26][27][28]. Some of the indices include the apparent temperature (AT), wet-bulb globe temperature (WBGT), standard effective temperature (SET), universal thermal climate index (UTCI), predicted mean vote (PMV), predicted percentage of dissatisfied (PPD), physiological equivalent temperature (PET), predicted heat strain (PHS), and summer simmer index (SSI).…”

“…In Equation ( 1), WBGT ind stands for indoor WBGT. The WBGT has been extensively explored in many studies using Equation ( 1) outlined in this study [26,28]. The SSI is a recent thermal index, propounded by Pepi and presented at the 2000 American Meteorological Society (AMS) Annual Meeting [27].…”

Colonial Revival style residences have unique architectural features amongst others. They are common multi-family residences in the United States with no or limited information about their performance. The research purpose is to assess indoor comfort, energy performance, and thermal indices in multi-family Colonial Revival style residences. The research questions include (i) Do Colonial Revival style buildings perform better than other old buildings? (ii) Do the buildings consume additional electricity than typical and other old buildings? The research examined four case studies in Hartford County, Connecticut. The investigation explored comfort surveys, monitoring, collection of actual electricity usage, and assessed thermal indices using mathematical models. The average indoor temperature of 25.4 °C and relative humidity (RH) of 61.3% are reported. About 67% of the residents are thermally comfortable. The research noted significance between thermal sensation and other variables, excluding how occupants feel about the air movement. The average number of hours of temperature exceeds 28.0 °C and 30.0 °C marks for over 11.4% and 2.5% of the time, respectively, except in one of the buildings. The mean indoor temperatures are within the applicable bands of the adaptive comfort models. The averages of actual thermal sensation vote (TSV) ranged from 3.32 to 4.37 on a 7-point sensation scale. The mean neutral temperatures varied from 24.2–25.6 °C. The average monthly electricity bill is within the national average for residences in summer, excluding in August. The mean wet-bulb globe temperature (WBGT) of 21.1–22.3 °C and summer simmer index (SSI) of 30.1–32.4 °C are calculated as feasible bands for thermal indices in the buildings. The basements are more comfortable than other spaces within the case studies. The research outcomes can be used for future developments of Colonial Revival style and other similar buildings. The study recommends interventions such as retrofit to improve the performance of some existing Colonial Revival style buildings, especially the older ones that are less insulated with outdated equipment and appliances.
