Incorporating simulation into building systems control logic

We present a prototypically implemented and empirically tested daylight-responsive lighting systems control in buildings that makes use of realtime sensing and lighting simulation. This system can control the position of window blinds and the status  of the luminaires. It operates as follows: (1) At regular time intervals, the system considers a set of candidate control states for the subsequent time step; (2) These alternatives are then virtually enacted via lighting simulation.

Influence of solar radiation data processing on building simulation results

A new set of climatic data for different kinds of calculations has been compiled for various Swiss localities. This includes the generation of new design reference year data sets with hourly values for e.g. building simulations. The procedure conforms to a set of new European standards describing the algorithms. One key element in this is the processing of solar radiation information, especially for the separation into direct and diffuse components. The most advanced methodology was used.


To examine present situation of energy consumption, an extensive survey was carried out as a projectof Architectural Institute of Japan (AIJ). More than 80 houses that were typical to the present Japanesehousing sector were chosen nationwide. As a part of this project, we measured the energyconsumption of 13 houses in Kansai region. The annual energy consumption in these13 houses rangesfrom 30 to 70 GJ from April 2003 to March 2004.

Use of IEA-SHC Task 21 C Benchmarks to assess performance of lightscape 3.2 in daylight calculations

In this paper, we use the validation test cases initialized within the subtask C, "Daylight design tools", of IEA SHC Task 21, "Daylight in buildings" to assess the accuracy of a commercial lighting software, Lightscape 3.2. We first analyzed the applicability and the limitations of the IEA 21 test cases, and we concluded some directives for validation test cases in order to guaranty its applicability to assess any lighting software.

A synergy-facade in a paslink test cell

This paper describes a modular facade system, which supplies the room behind with the necessary amounts of heat, light and fresh air. Aims of the development of this facade were both to achieve a high degree of comfort for the users and to save energy in comparison to a conventional facade. The experimental investigations to assess and to optimize the facade system were performed in a PASLINK test cell. These test cells allow measurements of the thermal and solar performance of facade elements in original dimensions and under natural climate conditions.

Optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices.

The aim of this paper is to explain the results of a research project run in Yildiz Technical University which focuses on the optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices placed in Istanbul city center. In this project, the building envelope alternatives are examined in terms of light, heat and sound considering the materials used mostly in Turkey.

Environmental quality assessment of classrooms

In this work a methodology for indoor environmental quality assessment was applied, based on thermal, visual, and acoustic comfort indices and on their analysis and spatial representation.Object of the study was one secondary school classroom of the Province of Torino (Italy), representative of several typologies of educational buildings, showing unsatisfactory environmental conditions.

Advanced façades and HVAC systems : preliminary results of full-scale monotoring

Double skin façades may help combine a high degree of transparency with high thermal and solar performance. Advanced façades serve as filters and may be responsive to changes in environmental conditions and occupant requirements. Since the strategies for

Analysis method of thermal and lighting environments and its application to the evaluation of office lighting

A method for analyzing the thermal and lighting radiations in offices building has been developed. It enables the simulation of complicated lighting environments composed of a combination of artificial lighting and solar radiation, in ventilated and air conditioned offices.

Evidence of a relationship between office design and self-reports of ill health among office workers in the United Kingdom.

Compares self reported health problems of employees in air conditioned open plan, non air conditioned open plan and conventional offices. The results showed overall that there is a significantly higher incidence of reported headaches among staff working in open plan offices compared with those in conventional offices. Problems of eye irritation and URT complaints are found to be most common among staff in open plan offices, but only when they are air conditioned and have poor daylight penetration. Women are the chief complainants. The problems are not strongly age dependent.
