Ultraefficient building environmental control technology

“超高效”建筑是指那些使用传统建筑50%或更少的能源的建筑。将对这类建筑物中的一些进行详细监测，以1)从能源效率和室内环境方面评估系统的性能，2)确定进一步提高性能的方法。使用地板下空气分布等系统的经验表明，建筑物的性能可能与计算机模拟和全尺寸模型预测的性能有很大差异。研究的技术包括辐射供暖和制冷、置换通风、地板下空气分配和采光。该研究将通过监测整个建筑和子系统的能源使用，以及通过测量热舒适条件和确定通风效果来进行。被研究的建筑将包括卡尔加里大学的儿童发展中心和AB瓦肯市的pririeview小学，模拟预计每年能源成本分别降低71%和53%。

"Ultra-efficient" buildings are those that use 50% or less of the purchased energy of a conventional design. A few buildings of this type would be monitored in detail to 1) evaluate performance of systems in terms of energy-efficiency and indoor environment and 2) identify approaches to further improve performance. Experience with systems such as underfloor air distribution has shown that performance in buildings may differ significantly from performance predicted by computer simulation and full-scale mockups. Technologies to be investigated include radiant heating and cooling, displacement ventilation, underfloor air distribution, and daylighting. The research would be carried out by monitoring whole building and subsystem energy use, as well as by measuring thermal comfort conditions and determining ventilation effectiveness. Buildings to be studied would include the University of Calgary's Child Development Centre and Prairieview Elementary School in Vulcan, AB, for which simulation projected 71% and 53% annual energy cost reductions respectively.
