Development of a multivariate regression model for overall satisfaction in public buildings based on field studies in Beijing and Shanghai

Indoor environmental quality assessment models: A literature review and a proposed weighting and classification scheme

“…Subjective-objective ( Figure 12a): Studies that attempt to correlate subjective and objective measures, providing equations that predict occupant satisfaction for each IEQ category based on objective measurements and overall IEQ as a combination of each sub-index [15,16,19,20,22]. This overall IEQ index is then compared to a fixed set of ranges that define the level of IEQ in the space or building.…”

“…We found eight studies that have proposed methods for evaluating indoor environmental quality in commercial buildings using a scoring/rating system [14][15][16][17][18][19][20][21][22]. The method used for selecting these papers is discussed in section 2.…”

“…However, for those studies that do not define classes directly in terms of occupant satisfaction, their classes can be traced back to occupant satisfaction studies. In order to use Cao et al [16], which used a regression scale from -1 to 1 (dissatisfied to satisfied), we chose to break that range evenly into five categories. Interestingly, because the satisfaction regression equations in this study resulted in low maximum satisfactions and high minimum satisfactions, there is actually never a score higher than 0.6 or a score lower than -0.6, meaning no one is ever quite "satisfied" or "dissatisfied" according to their definition of 1 as satisfied and -1 as dissatisfied.…”

“…Chiang et al [18] used an analytic hierarchy process (AHP) method which sampled 12 professionals to determine the appropriate weights. Wong et al [19], Cao et al [16], and Ncube et al [15] The weights proposed here were computed using a subset of the CBE survey database that was created for use in Frontczak et al, [52]. This subset database only included office buildings-further details of the database are included in Frontczak et al Occupant responses to satisfaction questions concerning the following variables were regressed against overall workplace satisfaction: (1) Acoustics: average of noise and sound privacy; (2) IAQ: air quality; (3) Lighting: average of visual comfort and amount of light; and (4) Thermal comfort: temperature.…”

The relation between indoor environnemental quality (IEQ) and energy consumption in building based on occupant behavior - A review

“…There are different group of chemical and biological pollutants in indoor air .There are different research which considered CO2 concentration as an IAQ Index [9][10][11]. The equation to calculate ventilation rate for considering IAQ based on CO2 concentration is:…”
