The Implementation of Visual Comfort Evaluation in the Evidence-Based Design Process Using Lighting Simulation

Abstract

Validation of the EBD-SIM (evidence-based design-simulation) framework, a conceptual framework developed to integrate the use of lighting simulation in the EBD process, suggested that EBD’s post-occupancy evaluation (POE) should be conducted more frequently. A follow-up field study was designed for subjective–objective results implementation in the EBD process using lighting simulation tools. In this real-time case study, the visual comfort of the occupants was evaluated. The visual comfort analysis data were collected via simulations and questionnaires for subjective visual comfort perceptions. The follow-up study, conducted in June, confirmed the results of the original study, conducted in October, but additionally found correlations with annual performance metrics. This study shows that, at least for the variables related to daylight, a POE needs to be conducted at different times of the year to obtain a more comprehensive insight into the users’ perception of the lit environment.

A Systematic Literature Review on Healthcare Facility Evaluation Methods

“…Furthermore, some EBD definitions emphasize that this “current best” corresponds to robust evidence or data from already built environments and credible collected user experiences, arising from an analysis based on recognized methods and rigorous studies, to influence both the design process and design results concerning the effects of the physical environment on well-being and their critical interpretation (Davoodi et al, 2021; Elf et al, 2019; Phiri & Chen, 2014a; Stichler & Hamilton, 2008; Vischer, 2009).…”

“…Some authors, such as Altizer et al (2019) and Davoodi et al (2021), cited Preiser et al (1988) to define POE as an evaluation process, carried out systematically and rigorously, in buildings constructed and occupied for some time—preferably, occupied for at least 6 months (Cranz et al, 2021). Ornstein et al (2009) pointed out that this process is a set of appropriate, comprehensive, and objective methods and techniques applied to the building in use, which include local and remote observation, such as walkthroughs, interviews with stakeholders, focus groups, and so on (Altizer et al, 2019; Barnes, 2002; Cranz et al, 2021; Ornstein et al, 2009).…”

“…Discussions on predesign evaluation (PDE), postoccupancy evaluation (POE), and EBD often intertwine, influence, and overlap each other. There is little published data on PDE (Cranz et al, 2021; Elf et al, 2019; Ornstein et al, 2009), and despite more advanced discussions (Brambilla & Capolongo, 2019; Brambilla et al, 2019; Coleman et al, 2018; Connellan et al, 2013; Davoodi et al, 2021; Elf et al, 2019; Joseph et al, 2014; Paraskevopoulou & Kamperi, 2018; Phiri & Chen, 2014b; Vischer, 2009), it is still difficult to establish an adequate and clear relationship between POE and EBD.…”

Ergonomic Rationalization Sequence of Digital Lighting Design in the Working Environment

“…Simulation tools to assess daylighting have been widespread in the construction sector since the 1970s. In the last decade, several authors have dealt with the lighting simulation tools issue [ 28 , 29 , 30 , 31 ], but the methodology of working with these tools was not addressed. In 2016, author Pawlak determined the performance accuracy of the simulation of escape route lighting installations, using the most popular programs supporting lighting design: DIALUX and RELUX, as well as possible errors associated with illuminance measurement of emergency escape lighting [ 32 ].…”

Transforming Building Criteria to Evidence Index

“…EBD is the antecedent of the building performance evaluation [16,17] and recent research has shown how EBD can be connected to digital tools, like lighting simulations [18]. This research has identified the importance of selecting KPIs (or metrics) for identifying evidence [19] during the evidencebased optimization (EBO). EBO and the current development of cognitive abilities of the building system could lead to better servitization of construction products (Figure 1).…”
