"Modelling, design and optimal operation of building-integrated solar and thermal systems"

建筑能源设计正在经历一个主要由三个关键因素驱动的重大变革时期： 1.发达国家和ASHRAE等有影响力的工程学会日益广泛地采用净零能源性能作为新建筑和社区的长期目标；为了以有效的方式实现这一目标，需要采用严格的量化方法将建筑设计为一个综合能源系统，该系统消耗低能耗，同时平均每年从现场生产等量的可再生能源；2.需要通过优化运行来减少建筑物的高峰电力需求，从而减少建造新的中央发电厂的需要；3.需要将新的先进多功能能源技术有效地整合到建筑物中，如半透明光伏、受控遮阳设备和储热设备。 该研究计划的长期目标是开发优化建筑能源性能的途径、程序和方法，将完全集成的太阳能系统的现场发电与能效措施和优化控制相结合。短期研究目标是： 1.模拟和设计将太阳能利用和能源效率结合在一起的新型建筑围护结构概念和系统，例如窗口系统，它集成了半透明的光伏电层用于发电，同时传输日光并可能产生有用的热量。改善能源性能，同时优化周边区域的舒适性。 2.开发基于模型的预测控制策略，通过控制有源围护结构系统(如电动遮阳和采光设备)来优化太阳能增益利用，以在实现良好舒适性的同时减少对电力的高峰需求。 3.为太阳能社区制定优化的能源设计和控制概念，以确定实现净零能源的最佳途径，同时对电网产生可预测的影响。

Building energy design is going through a period of major changes driven largely by three key factors: 1.The increasingly widespread adoption in developed countries and by influential engineering societies such as ASHRAE of net-zero energy performance as a long term goal for new buildings and communities; to achieve this goal in an efficient way, a rigorous quantitative approach is required to design a building as an integrated energy system that consumes low amounts of energy while producing in an average year an equal amount of energy on-site from renewables; 2. The need to reduce the peak electricity demand for buildings through optimal operation, thus reducing the need to build new central power plants; 3. The need to efficiently integrate new advanced multifunctional energy technologies into buildings such as semitransparent photovoltaics, controlled shading devices and thermal storage. The long term goal of the research program is the development of pathways, procedures and methodologies for optimal energy performance of buildings that combine on-site energy generation from fully integrated solar energy systems with energy efficiency measures and optimal control. The short term research objectives are: 1. Modelling and design of novel building envelope concepts and systems that combine solar energy utilization and energy efficiency such as fenestration systems that integrate semitransparent photovoltaic layers for electricity generation while transmitting daylight and also possibly producing useful heat. Improve energy performance while optimizing comfort in perimeter zones. 2. Development of model-based predictive control strategies that optimize solar gain utilization through control of active envelope systems (such as motorized shading and daylighting devices) to reduce peak demand for electricity while achieving good comfort. 3. Development of optimized energy design and control concepts for solar communities so as to determine optimal pathways to reach net-zero energy while having a predictable impact on the grid.
