The purpose of this paper is to assess the health and wellbeing implications of working in adeep plan office building in a temperate climate and illustrate how office design can add to ordetract from productivity.The authors have carried out post occupancy evaluation surveys on employees before andafter the move from a naturally ventilated, shallow plan office to a deep plan, air-conditionedoffice. The workforce and workload remained constant, which enabled true comparisonbetween building types.

Environmental temperature in which perform commercial hybrids on privately-owned family farms in the Banat area (România) has a strong impact on the valorisation of feed and particularly on energy, as there is an optimal temperature at which feed is valor

This paper presents an evidential review of current knowledge on the issue of walking versus sedentary behaviour in office environments. It considers the medical evidence in relation to cardio-vascular activity and the long-term effect of sedentary compared to mobile work routines. The paper then goes on to consider the concept of embedded health within buildings, reflected in the way that buildings are designed and managed. It highlights in particular the role of the facilities manager in enabling such embedded health.

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

Field studies have shown that speech is the most distracting sound in open-plan offices. On the other hand, laboratory studies have shown that speech impairs the performance of cognitively demanding work tasks, e.g. reading and memory-recall tasks. The sound level of speech does not determine the degree of distraction caused by speech. Instead, Speech Transmission Index, STI, which correlates with speech intelligibility can explain the distracting power of speech much better. STI can be determined also between workstations in open offices.

A computer program for both field survey and laboratory experiment was developed toevaluate performance of office works and to link the findings from experiments to the actualoffices. The program has three parts: namely, Voting Tool, Task Tool, and PerformanceEvaluation Tool. In this study, the Performance Evaluation Tool, which is consisted of twelvestandard tests, was examined. The abilities required for the office works in two companiesand one branch of the government office were collected to verify the applicability of thePerformance Evaluation Tool.

A long-term field study was conducted in an office for seven months to clarify the effect of thermal environment on productivity. Seven male software programmers participated as subjects. They answered the questionnaires on their personal computer including thermal sensation votes, complaints about their working environment, fatigue, vitality, mental workload and self estimated productivity every workday. The numbers of keystrokes were automatically recorded during the operation of their computers. Advanced Trail Marking Test (ATMT) was also conducted as the estimation of performance.

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).
