  In this paper, the authors present the results of a laboratory test where two reinforced concrete beams were instrumented with Distributed Optical Fiber Sensors (DOFS) to allow the monitoring g of strain in four different ...
• U-value time series analyses: Evaluating the feasibility of in-situ short-lasting IRT tests for heavy multi-leaf walls 

  Tejedor Herrán, Blanca; Casals Casanova, Miquel; Macarulla Martí, Marcel; Giretti, Alberto (2019-07-15)
  Article
  Restricted access - publisher's policy

  A gap in standardization of quantitative infrared thermography (IRT) directly leads to a lack of measurement pattern for determining in-situ U-values of heavy multi-leaf walls. Three groups of causal factors might influence ...
• Analysis of building maintenance requests using a text mining approach: building services evaluation 

  Bortolini, Rafaela; Forcada Matheu, Núria (2019-05-16)
  Article
  Restricted access - publisher's policy

  End users’ maintenance requests gathered from computerized maintenance management systems (CMMS) configure a rich source of information to evaluate the occupants’ satisfaction and the building systems. Nevertheless, the ...
