A subjective experiment was conducted in a climatic chamber to evaluate the effects of improvement of indoor environmental quality on occupant’s performance. The chamber was conditioned with the combination of: operative temperatures of 25°C or 28°C, illu

This paper presents the development of distribution models of office employee’s thermal sensation and an introduction to a methodology how to integrate the fact that humans perceive temperature differently with the effects of temperature on mental perform

The impact of the work motivation on the occupants’ work performance of serial one-figure addition task and proofreading task was studied in two types of experiments, i.e., type A of cool condition (22 deg C) and type B of neutral condition (25 deg C). Du

This paper presents a case study of a typically poor energy performing factory building singled outfrom nation-wide study on factory buildings for improving energy performance. Short term energymonitoring has shown that lighting system is the main energy consumer of landlord area energyusage in these naturally ventilated factory buildings. It aims to maximize significant energyperformance upgrading opportunities in the lighting system and explore the use of photovoltaics toachieve low-energy factory buildings.

Nowadays energy performance is an increasing concern to sustainable urban planning because of itsimplications in energy consumption patterns. Interactions between urban form and urban microclimatehas been broadly studied from large scale such as the city as a whole through heat island studies.However urban planning needs to be addressed at local scale as well.The purpose of the work is to study experimentally thermal conditions on outdoor spaces within theurban fabric at neighbourhood scale in Santiago city, Chile.

Vegetation on the building envelope can have a marked effect on the microclimate and on the building’s energy behavior as well. In this paper, the impact of planted roofs on the thermal load of buildings is presented. Based on measurements and a series of

This work proposes a mathematical dynamic modeling of a PV-T bi-fluids collector prototype that willpermit electricity production and preheating air and/or hot water production.This study is realised in a bi-dimensional geometry according to some assumptions. The collector is discretizedalong the flow and the collector slope is taking into account in the radiative transfers equations.

The Singular Strategic Project called Bioclimatic Architecture and Solar Cooling, ARFRISOL (ARquitectura bioclimática y FRIo SOLar, in Spanish), has been promoted and supported by Spanish Ministry of Education and Science (MEC). This project plans to save

This paper introduces a new approach for the prediction of hourly energy consumption inbuildings. The proposed method uses nonlinear timeseries analysis techniques for thereconstruction of energy consumption timeseries and the estimation of the dynamicinvariants, and artificial neural networks as a nonlinear modeling tool.Among the several neural network modeling factors that affect time-series prediction, themost important are the window-size and the sampling lags for the data.
