“…Although IVE was not widely adopted in colour research, some studies have demonstrated the feasibility of IVE used in light and space simulations for the interior environment [12,14]. These may potentially support this study to examine the feasibility of applying IVE in colour research.…”

Interior design elements, particularly colours, have shown significant influence on employers' performance in office environments. The task performance was often measured against different coloured offices in physical built environments. An identified challenge for these studies is to alter colour settings for experiments. Immersive virtual environment (IVE), as an advanced technology, may potentially address to this challenge. Although few studies applied IVE in colour related research, some studies have successfully applied IVE in light and space research for performance assessment. These studies underpin this research to examine the feasibility of applying IVE in colour studies. A virtual model of office environment was built and rendered in Autodesk building design suite (Revit and 3Ds MAX) and presented in Virtual Desktop. Within the virtual offices, only the wall colour was changed while the other parameters remained the same. This enabled the task performance to be measured in the IVE-made offices with different colours (including white, red, green and blue). Proofreading tasks were used for measuring the task performance in each coloured office. The data of error numbers and time expense were collected and then analysed by the analysis of variance (ANOVA). Two significant findings were identified. Firstly, compared to the other three colours, task performance in the white offices was the best. Secondly, performing tasks in red office has better performance than green and blue offices. These two significant findings were supported by several colour related studies although there were some research presenting different results. This study demonstrated the potential of applying IVE for interior colour research in office environments. This study can support a further assessment for the feasibility of IVE by evaluating human emotion and physiological conditions for our funded project.

“…Em iluminação, a realidade virtual é utilizada para analisar a preferência de usuários quanto ao controle lumínico em ambiente de escritório (Heydarian et al, 2015a(Heydarian et al, , 2015b. Portanto, o papel desses recursos é garantir que as ideias traduzidas em imagens e textos no processo de planejamento sejam transformadas em realidade antes da finalização do projeto.…”

Licenciado sob uma Licença Creative Commons Impressões qualitativas em espaços urbanos noturnos por meio de ambientes virtuais imersivos Qualitative impressions in urban spaces at night through immersive virtual environmentsÍtalo Pereira Fernandes [a] , Norberto Corrêa da Silva Moura [a] , António Aguiar Costa [b] [a] Universidade de São Paulo (USP), São Paulo, SP, Brasil [b] Instituto Superior Técnico Lisboa, Lisboa, Estremadura, Portugal ResumoPesquisas no âmbito da iluminação focam no aspecto quantitativo e físico dos efeitos lumínicos e seu desempenho na relação usuário-ambiente. Assim, estudos sobre os aspectos subjetivos da iluminação e sua influência na percepção e no usufruto do espaço são crescentes, porém existem poucos experimentos para avaliar impressões subjetivas dos ambientes noturnos. O presente artigo tem por objetivo mapear qualidades ambientais do espaço urbano localizado na cidade de João Pessoa-PB por meio do conceito de atmosfera percebida, cuja categorização de palavras descreve qualitativamente o ambiente, utilizando o ambiente virtual tridimensional como suporte para criação e avaliação de cenários noturnos. Nesse sentido, foram simulados, em realidade virtual, dois projetos de iluminação: uma paisagem noturna existente e uma proposta de intervenção como alternativa, a fim de gerar avaliações pelos usuários. Os resultados mostram que existem qualidades subjetivas diferentes nos espaços, relacionadas com questões de segurança e sociabilidade do ambiente, o que reflete a importância dessas avaliações subjetivas, e demonstram o contributo da realidade virtual como aspecto inovador nesse processo. Contribuições do artigo dizem respeito à participação coletiva no processo de projeto e aplicação da metodologia em contextos em que a iluminação é fundamental, como espaços públicos de conjuntos habitacionais.

“…In another study, the authors investigated how human performance, perception and behaviour differ in an immersive virtual environment compared to an actual physical environment [8] and found no noticeable difference in terms of human performances between the two environments. The use of IVEs gives the researchers an opportunity to create environments with various control settings and evaluate end-users' behaviour and preferences given different scenarios.…”

-Recent studies have focused on increasing energy efficiency in commercial buildings through technological means (e.g., efficient HVAC systems, sensors and sensing systems). However, most studies underestimate the impact of occupants' behavioural choices. Lighting systems account for approximately a fifth of the total electricity consumption in the US; commercial buildings account for 71 percent of such consumption. This paper focuses on human behaviour related energy consumption by investigating the impact of personal control on lighting use in office environments. To effectively examine human energy consumption behaviour, alternative 3D design models of an office are created using an immersive virtual environment to visualize different lighting control features. Participants are brought into these immersive virtual environments by wearing Head-Mounted Displays and are asked to interact within these environments and perform a defined task. Participants were then allowed to control and change the room's lighting settings based on their preferences in order to perform their assigned task. Unique to our experimental design is the use of immersive virtual environments, enabling measurement and control of a series of design feature isolations and combinations. The work presents the impact of decisions made both during design and operation of buildings on occupants' energy related behaviour. The experiment demonstrated that when participants are provided with personal controls for the blinds and the artificial light, there is no significant difference in their preferences between natural and artificial lighting; however participants are significantly more likely to open the blinds remotely if they are only provided with a personal control for the blinds.
