Indoor environmental quality assessment: Part 1: Choice of the indoor environmental quality sub-component models

Abstract

Indoor environment quality is a relative measure of comfort perception by people exposed to the indoor conditions. It is expected that any assessment of energy performance should also include indoor comfort. This study is to review indoor environmental quality models (with respect to thermal and acoustic comfort, indoor air and lighting quality). A simplified indoor environmental quality model is also developed with consideration of EN 15251 draft ‘Guideline for using indoor environmental input parameters for the design and assessment of energy performance of buildings’. This article analyses what components should be modelled and in particular discusses the effect of different weighting schemes on the overall indoor environmental quality index. The analysis includes thermal comfort models, indoor air quality, acoustic comfort and daylight illumination versus lightning. The proposed indoor environmental quality component sub-models will give the most reliable results when the model indoor environment input data are correctly measured and disturbing influences of indoor environmental quality monitoring process are well defined and properly assessed. The final indoor environmental quality result is based on subjoining the uncertainty values achieved in panel analysis of percentage of persons dissatisfied with indoor environmental quality with corrected measurement uncertainty. All simulations for IEQindex sub-components and preliminary metrological analysis of the whole indoor environmental quality model were performed with the NIST program for Monte Carlo tests. The presented indoor environmental quality model proposal is developed to support engineers’ practice as the convenient tool for a practical assessment of building’s occupational satisfaction.

Air Enthalpy as an IAQ Indicator in Hot and Humid Environment—Experimental Evaluation

“…Continuous CO2 measurement was carried out during the experiment by a FYAD00 sensor and other side devices integrated with the building management system (BMS). The mean carbon dioxide concentration during tests was 650 ± 15 ppm, which corresponds to a neutral percentage of dissatisfaction (PDCO2 < 10%) in accordance to Reference [45] and [46]. During day 1 and day 2, a measurement of volatile organic compounds (VOCs) air pollution was carried out.…”

Practical Implementation of the Indoor Environmental Quality Model for the Assessment of Nearly Zero Energy Single-Family Building

“…Indices were calculated based on the indoor measurements of the physical properties in each of the sub-models in accordance with the IEQ Piasecki-Kostyrko model. Sub-component models were developed and presented in the literature [5,22] based on sensory studies in panel groups. This included research by the author [23,24].…”

“…Currently, the indoor environmental quality (IEQ) problem is widely discussed but there is still no simple tool and approach at the disposal of engineers. Responding to this technical and environmental challenge, the researchers of Building Research Institute ITB have been investigating this issue since 2015 and the research results are currently promising [5]. Findings are disseminated in a case study of a real building assessment.…”

Analysis of the Effect of Using External Venetian Blinds on the Thermal Comfort of Users of Highly Glazed Office Rooms in a Transition Season of Temperate Climate—Case Study

“…Studies are directed towards improving the comfort model [12,13] through a number of experimental tests in laboratories, as well as in real-life objects [14,15]. Many researchers include thermal comfort into indoor environment quality models, additionally taking into account acoustic and lighting comfort and proposing modifications [16][17][18][19].…”
