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

The impact of simultaneous short-term exposure to three environmental parameters (temperature,noise and air quality) on human perception and performance was studied in two identical climatechambers. Eight conditions were created exposing the subjects for 20 minutes to combinations oftwo levels of operative temperature (23,5 C and 28,0 C), two noise levels (52 dB(A) and60 dB(A)) and two pollution loads (pollution load absent, pollution load present).

To promote the effort for energy conservation, it is also important to estimate the indoorenvironmental quality (IEQ) from the aspect of office workers productivity. A conceptualdiagram for the evaluation of the effect of IEQ on productivity was proposed. The resultsfrom subjective experiments of short term showed that human responses, such as fatigue,cerebral blood flow, sensation to the environment and SBS symptoms, were important for theevaluation of productivity.

Although there is significant support among policy makers and politicians for energy efficiencyimprovements in buildings, there remains a lack of understanding of what policies (regulatory,economic, communicative and organisational) can deliver these changes on the ground. The blueprintstudy attempts to address this gap.

The EIE 2003 SAVE ENPER EXIST project (www.enper-exist.com) aims to address the specificproblems of the existing buildings in the scope of the introduction of the Energy Performance ofBuildings Directive (EPBD).In this project a specific work package (WP4) aim to develop a long-term roadmap for definingpossible measures going beyond the EPBD allowing existing buildings to become more energyefficient.The main objectives of the task are:- To give an overview of possible legal measures for existing buildings with illustration byavailable examples and pr

This paper is part of the “Best Practice for Double Skin Facades” – ‘BESTFACADE’ project (supported by the Intelligent Energy Europe Programme of the European Community) and aims to describe the cut back of non-technological barriers to the application of

The project BESTFAÇADE accumulated the state of the art of double skin façades in seven European countries (Austria, Belgium, France, Germany, Greece, Portugal and Sweden). 28 façades of different buildings in all partner countries of BESTFAÇADE have been

Double skin facades have become a major architectural element in office buildings over the last 15years. A double skin facade can provide a thermal buffer zone, solar preheating of ventilation air,energy savings, sound protection, wind and pollutant protection with open windows and nocturnalcooling. Commercial buildings with integrated double skin facade can be very energy efficientbuildings with all the good qualities listed above.However not all double skin facades built in the last years perform well.

This paper describes ongoing energy benchmarking studies of double-skin façade buildings. Benchmarking methodology is discussed. Some preliminary results are presented.
