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.

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned. Therefore more and more of these buildings are being built with doubleskin facades, which can provide: a thermal buffer zone, energy savings, wind protection with openwindows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, pollutantprotection with open windows, nocturnal cooling and a site for incorporation of PV cells.

The objective of the paper is to present a new educational concept for improving the accessibility towhole building Heat, Air & Moisture (HAM) simulation models developed in the simulation environmentHAMLab. We provided a library of buildings, including the default performances of the buildingsthemselves, on a website. Students can select the most appropriate building, adapt the inputparameters, simulate and evaluate the results. In case a higher resolution is required, two stepsexplain how to implement respectively advanced controllers and HAM details.

The aim of the Pythagoras project is the development and assessment of Greek national trainingmaterial in the sector of indoor environmental quality. The need for education in this specific sector isdictated by the significant indoor environment deterioration and associated health hazards, which arecaused by low ventilation levels, combined with the use of many modern building materials thataggravate pollutants emissions.
