考虑到大型建筑空调系统的新方法和系统，实验室测试和计算机建模是我们使用的重要工具。然而，当建筑完工并被占用时，我们必须忍受的公用事业费用和生活舒适度决定了项目的成功程度。在新项目设计中，必须同等考虑系统和方法的实际性能和经验。对一些采用现代系统和控制方法的购物中心进行了监控，并将其与采用原始和现代控制系统的旧建筑进行了比较。 实际经验的结果总是与同时发生的几个事件混合在一起。结果与建筑类型、建筑、占用、设计、地点、天气以及其他任何我们想考虑的因素不同。必须使用几个具有代表性的建筑，考虑各种控制策略的实际建筑经验的结果，以便建立足够的数据库。引文:研讨会，ASHRAE交易，第87卷，第一部分，伊利诺伊州芝加哥

Laboratory testing and computer modeling are important tools we use in consideration of new methods and systems for large building air-conditioning systems. However, when the building is completed and occupied, it is the utility bills and creature comfort we all must live with that determine the degree of success of the project.Actual performance and experience with the systems and methods must be given equal consideration in new project design.Some shopping centers with modern systems and control methods have been monitored and compared to older buildings with both original and modern control systems.The results of actual experiences are always mixed with several events happening at once. Results vary with building type, construction, occupancy, design, location, weather, and any other factors we wish to consider. The results of actual building experiences with various control strategies must be considered using several representative buildings so that a sufficient data bank is established.
