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.

建筑节能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越来越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该目标，需要采用严格的定量方法，将建筑物设计为一个综合能源系统，该系统消耗低量的能源，同时平均每年产生等量的能源，可再生能源; 2。需要通过优化运行降低建筑物的高峰用电需求，从而减少新建中央发电厂的需要; 3.需要将新的先进多功能能源技术有效地纳入建筑物，如透明光电池、受控遮阳装置和蓄热装置。 该研究计划的长期目标是开发途径，程序和方法，以优化建筑物的能源性能，将联合收割机从完全集成的太阳能系统现场发电与能源效率措施和最佳控制相结合。短期研究目标是： 1. 新型建筑围护结构概念和系统的建模和设计，这些概念和系统结合了联合收割机太阳能利用和能源效率，例如集成了用于发电的透明光伏层的开窗系统，同时传输日光并可能产生有用的热量。提高能源性能，同时优化周边区域的舒适度。 2. 开发基于模型的预测控制策略，通过控制主动围护系统（如电动遮阳和日光照明设备）来优化太阳能增益利用，以减少电力峰值需求，同时实现良好的舒适性。 3. 为太阳能社区开发优化的能源设计和控制概念，以确定达到净零能源的最佳途径，同时对电网产生可预测的影响。
