项目摘要

The design and control techniques for optimizing the intelligent office environment were developed from the viewpoint of both the energy conservation and amenity.1. Regional and simplified estimation method of heating requirements at the preheating period which decided the heating capacity of perimeter zone was established. The optimum selection method of outdoor design condition based on the risk level of the environmental condition was provided. These were obtained using the dynamic load calculation method. The mixing energy loss in a space simultaneously heated and cooled was quantified through lots of experiments in a simulated full-scale office room. Multidimensional equations to calculate the loss were derived, and the seasonal energy losses were were estimated under various conditions.2. The thermal environment in the office room where the low temperature air was directly discharged with the reduced air flow rate was analyzed through lots of experiments in the room above stated. … More The space air diffusion and human physiological and psychological response were measured and evaluated. No problem was found in the air conditioned room using such a low temperature air from the viewpoints of thermal comfort but gave much more energy conservation effect.3. The performance of the floorーbased airーconditioning system was analyzed using the aboveーmentioned methodology. The optimum design/control conditions for the discharged cool air were established.4. The visual environment in the intelligent office was studied experimentally from the viewpoints of developing physical suitable to evaluate the visual performance, and the optimizing lighting techniques. The reflection of the worker on the VDT had inappropriate influence on the visual performance. It was turned out that the louverーmounted lighting device was not so effective for preventing the phenomenon. The vertical plane illuminance was found to be suitable for evaluating the modeling.5. The increase in the fire hazard due to the installation of the work-stations was investigated using the simulation techniques. Installing the workーstations increased the transmission velocity of the smoke to the upper floor. The failure rate of the emergency lighting devices and the fire doors was quantified statistically from many field data.6. Intelligent office environment increases the effectiveness and amenity due to the information network system. The relation among BEMS, FM and MIS was made clear and the direction of integrated building infomation system was proposed. Less

从节能和舒适的角度出发，研究优化智能办公环境的设计与控制技术。建立了决定周边区域供热容量的预热期供热需求的区域简化估算方法。提出了基于环境条件风险等级的室外设计条件优选方法。这些是采用动载计算方法得到的。在模拟的全尺寸办公室内，通过大量的实验，量化了同时加热和冷却的空间内的混合能损失。推导了计算损失的多维方程，估算了不同条件下的季节能量损失。通过在上述房间的大量实验，分析了以减小的风量直接排出低温空气的办公室内热环境。对空间空气扩散和人体生理心理反应进行了测量和评价。使用这种低温空气的空调房间从热舒适的角度来看没有问题，而且节能效果更好。采用上述方法对地板空调系统的性能进行了分析。确定了排风量的最佳设计/控制条件。从开发物理适宜度评价视觉性能、优化照明技术等方面对智能办公的视觉环境进行了实验研究。工人在VDT上的反射对视觉表现有不适当的影响。事实证明，安装在百叶窗上的照明装置对防止这种现象并不是那么有效。发现垂直平面照度适合于评价模型。利用模拟技术，研究了由于工作站的安装而增加的火灾危险。安装工作站增加了烟雾向上层的传播速度。根据大量现场数据，对应急照明装置和防火门的故障率进行了量化统计。由于信息网络系统的存在，智能办公环境增加了办公的有效性和舒适性。明确了BEMS、FM和MIS之间的关系，提出了综合建筑信息系统的发展方向。少
