Green building is deemed an effective means to realize the sustainable development of environment, economy and society in the construction industry. Green building technologies (GBTS) are important to realize green buildings. In order to make the application of GBTS be adopted and popularized effectively, it is especially important for us to gain thorough comprehension of the key problems that affect the adoption of GBTS. The target of this paper is to better understand the adoption of GBTS from the perspective of designers. This article utilizes a questionnaire to investigate Chinese architectural designers. Through establishing a structural equation model and an analysis of the survey data, the key factors influencing the adoption of GBTS by designers in the Design Company were found out. The results denote that the adoption motivation, the capability of GBTS, the knowledge structure and the defects of GBTS are the significant factors that affect designers' adoption behaviors. However, the management support of GBTS has no significant effect on designers' adoption behavior. The research results are helpful to improve adoption of GBTS in design units and accelerate the transformation of GBTS achievements. Additionally, they can promote the application of GBTS in the field of construction. Based on the quantitative theoretical model (the structural equation model), this paper finds out the key factors that affect the application of GBTS from the perspective of designers, enriching the theoretical methods of GBTS research and complementing the relevant literature of GBTS research. Future research will analyze the adoption behavior of GBTS from the point of other stakeholders and from the internal level of the design units.Sustainability 2018, 10, 4135 2 of 22 environmentally responsible and improve the effective utilization of energy efficiency" [7]. Because of the negative impact of conventional buildings on both the environment and the climate, green buildings are perceived as effective substitutes for traditional buildings. It plays an important role in environmental protection and resource conservation [8,9].GBTS are an important means to improve energy efficiency and an effective way to realize green building [10,11]. In recent years, due to its advantages, there has been some research on GBTS. From the perspective of the whole life cycle of architecture, researchers study the environmental pollution and other issues [10][11][12][13][14][15]. GBTS include solar systems, green roofs and walls, heat pumps and the application of corresponding technologies throughout the construction project delivery process [8,13,16]. Some GBTS, such as green roofs, solar energy and precast concrete, have been introduced into the development of green projects. Green buildings are required to integrate the interactions between GBTS and other building components to reduce the impact on the environment [17,18]. Building energy efficiency can be remarkably improved by the use of GBTS to renovate existing buildings [15,19]. A large n...

“…Dr. Pieter de Wildehas adopted a survey of 67 buildings in Europe. The result shows that, among 303 GBTS, 57% of technical measures should be implemented in the planning and design phase [30]. The adopting of GBTS advocates a participatory design process [31].…”

“…A termografia passiva não requer fontes de estimulação externa (Oh et al, 2013), usa a energia solar e a temperatura ambiente como principais recursos de aquecimento, e é a técnica utilizada para inspeção de pontes (Kee et al, 2012;Vaghefi et al, 2012;Alfredo-Cruz et al, 2015), bem como para outras estruturas e outros campos (Buyukozturk, 1998;Lahiri et al, 2012;Barreira;Almeida;Delgado, 2016;Fox;Goodhew;Wilde, 2016;O'Grady;Lechowska;Harte, 2016). Em contraste, a termografia ativa requer fontes externas de estimulação de calor (Kee et al, 2012;Rehman et al, 2016), pode até ser sub-dividida de acordo com a natureza da estimulação como: Pulsed, Lock-in, Pulsed-Phase, entre outros (Maldague, 2001).…”

“…McCann e Forde (2001) apresentam uma variedade de métodos não destrutivos adequados para obras de construção civil, e, especificamente Rehman et al (2016), apresenta em detalhe os ensaios não destrutivos para a inspeção de pontes. A termografia infravermelha como um ensaio não destrutivo tem sido utilizada para a inspeção de estruturas civis com resultados satisfatórios (Meola, 2007;Fox;Goodhew;Wilde, 2016;Hiasa;, e a sua aplicação especifica na inspeção de pontes está cada vez mais consolidada (Watase et al, 2015;Ellenberg et al, 2016;Dabous et al, 2017;Hiasa;Catbas, 2017a). No entanto apresenta algumas limitações quanto: à profundidade de detecção de defeitos, a influência das condições ambientais, o horário de coleta de dados, entre outros.…”

RESUMOEste artigo tem como objetivo apresentar as metodologias, vantagens e limitações do ensaio da termografia infravermelha para a inspeção de pontes de concreto armado. Foi realizada uma revisão sistemática de artigos e de material acadêmico relativo à área. Esta revisão foca-se principalmente na aplicação passiva e em estudos tanto de laboratório quanto de campo. Utilizou-se uma abordagem crítica da informação disponível quanto a seu alcance. A termografia infravermelha apresenta-se como uma alternativa real para a detecção de defeitos nestas estruturas, sendo mais eficaz quanto mais superficiais sejam estas anomalias. Dependendo do trabalho a ser realizado é necessário levar em conta algumas considerações para obter melhores resultados. E é eficaz em combinação com outros ensaios. Palavras chaves: termografia infravermelha; inspeção de pontes; patologias do concreto. _______________________________________________________________

“…The EViz project and others (Burchell, Rettie, & Roberts, 2015;Morris-Marsham, 2014) have explored TI as a tool to improve the cognitive connection between conservation behaviour and consumption (Boomsma et al, 2016) and to demystify heat (Goodhew, Boomsma, Pahl, & Goodhew, 2015) in order to promote energyconservation behaviours (Goodhew, Pahl, Auburn, & Goodhew, 2015). Thermographic images can be used in a number of ways to provide feedback through either individual household surveys or community-wide surveys (Fox, Goodhew, & De Wilde, 2016), and public display of the results to enable comparative feedback and information on potential issues and solutions.…”

Most research to date on the provision of energy feedback to households has focused on assessing the efficacy of numeric-based feedback. This paper describes the application and evaluation of more visual energy feedback techniques (carbon mapping, thermal imaging) at different scales, alongside traditional methods (web-based energy and environmental visualization platform, home energy reports) delivered through community workshops, home visits and the internet, across six low-carbon communities in the UK. Overall, most of the feedback approaches were able to engage and raise awareness amongst the householders. Whilst carbon mapping was felt to be aimed more at community groups and local councils by providing evidence of past and future community action, displaying carbon maps at community workshops helped to show that others were also engaged in energy action. Thermal imaging was successful in engaging individual local residents through both community workshops and home visits, especially when included in the home energy reports. This stimulated discussions on future energy savings through building fabric upgrade. However, the data-driven web-based platform had limited uptake due to online log-in requirement and information overload. Such insights are useful for those involved in scaling up the deployment of energy feedback to encourage energy demand reduction.
