Design of thermally comfortable and healthy buildings: integration of concrete heated floor system

该项目的主要目标是开发一种有效的设计工具和控制策略，用于与混凝土加热地板集成的建筑物的操作。电加热地板可以在非高峰期将热能储存在建筑物中，并在高峰期释放热能。在这种方法中，通过在混凝土板中放置电阻来对地板进行电加热。在加拿大的住宅建筑中整合这项技术以减少或转移热负荷是一个具有挑战性的问题，因为这些建筑是轻型建筑，主要地板由胶合板制成，没有热质量。然而，几乎所有的住宅楼都有地下室，地下室配有平板混凝土地板。挑战是使用混凝土加热地板作为热质量激活剃须和转移的demands.The短期目标的研究项目是开发设计和控制工具，将预测，操作和评估建筑物的性能与集成混凝土加热地板系统。该系统的设计还必须满足建筑主楼层居住者的实际需求，并且必须成为建筑设计系统的一个组成部分。本研究的结果将为建筑施工中混凝土加热地板的设计、开发和集成提供系统的方法，这将提高能源效率，同时确保建筑居住者的热舒适性和健康。并有助于将建筑物的热负荷从高峰期转移到非高峰期。

The main objective of this project is to develop an efficient design tool and control strategy for the operation of a building integrated with concrete heated floors. Electrically heated floors can store thermal energy in building during off-peak periods and release it during peak periods. In this approach, a floor is heated electrically by placing an electrical resistance into a concrete slab. Integration of this technology in Canadian residential buildings for the purpose of shaving or shifting thermal load is a challenging issue, as these buildings are lightweight constructions and the main floors are made up of plywood and have no thermal mass. However, almost all residential buildings have a basement, and the basement is furnished with a slab concrete floor. The challenge is to use the concrete heated floor as thermal mass activation to shave and shift the demand.The short-term objectives of this research project are to develop design and control tools that will predict, operate, and evaluate the performance of buildings with an integrated concrete heated floor system. This system must also be designed to respond to the actual needs of building occupants on the main floor, and it must be an integral part of the system of the building design.The outcomes of this research will provide a systematic approach for the design, development, and integration of concrete heated flooring within building construction, which will improve energy efficiency while ensuring thermal comfort and health to building occupants, and helping to shift the building's thermal load from peak periods to off-peak periods.
