This paper presents the energy and economic analysis used to determine cost effective requirementslevels to the thermal standard for buildings in Lebanon. The heating and cooling energy use fordifferent buildings types (18 buildings) according to the variation of envelop parameters was simulatedfor realistic cooling and heating schedules and five Lebanese climatic zones. Parameters investigatedincluded, construction type, insulation levels, window sizes and solar protection. The energysimulation program VISUAL-DOE.3 was used for the energy use simulations.

The paper evaluates the potential work performance benefits of increased ventilation. We analysed the literature relating work performance with ventilation rate and employed statistical analyses. The studies included in the review assessed performance of various tasks in laboratory experiments and measured performance at work in real buildings. Almost all studies found increases in performance with higher ventilation rates. The studies indicated typically a 1-3 % improvement in average performance per 10 L/sperson increase in outdoor air ventilation rate.

As part of the European SAVE project ENPER, an international workshop on the implementation of the European Energy Performance Directive (EPD) was organised in Brussels on May, 19. Some 115 delegates from 21 countries attended this workshop. This directive obliges the Member states as well as the 10 candidate members to implement a range of regulatory measures regarding the energy performance assessment and certification of buildings. Presentations were made by the people listed above in the author grid.

Thirty subjects (17 female) were exposed for 5 hours in a climate chamber to clean air at 5%, 15%, 25% and 35% RH at 22 °C, in balanced order. Another 30 subjects (15 female) were similarly exposed to air polluted by carpet and linoleum at 18, 22 and 26 °

The objective of this study was to test a new office space where the environmental conditions could be well controlled- a "field laboratory", located at Mid Sweden University in 6stersund. To test the laboratory, the same experiment that had been carried out earlier at the Technical University of Denmark (DTU) was repeated. A further objective was to test whether the earlier results from DTU showing a negative impact of increased indoor air pollution on perceived air quality, Sick Building Syndrome (SBS) symptoms and performance could be repeated.
