The long term goal of the proposed research program is the investigation of pathways to optimal energy performance of buildings and building clusters that combine on-site energy generation from fully integrated solar energy systems with thermal energy storage, energy efficiency measures and optimal control. The short term research objectives are as follows: 1. Study and development of advanced building envelope systems that combine several functions in order to reduce cost while maximizing energy efficiency such as fenestration systems that integrate semitransparent photovoltaic layers to generate electricity while transmitting daylight and also possibly producing useful heat. 2. Study and development of predictive control strategies that optimize solar gain utilization through control of active envelope systems (such as shading and daylighting devices) to reduce peak demand for electricity while achieving good comfort. 3. Development of integrated energy design and control concepts for groups of buildings or communities so as to determine optimal pathways to reach net-zero energy while having a predictable impact on the electric grid demand profiles. The work related to the first objective will involve first exploration of the potential energy performance of different façade concepts that optimize solar energy utilization by harnessing nearly the full spectrum of sunlight to generate electricity, as daylight and the remainder as useful heat. Promising configurations will be studied through integrated energy simulations using lumped parameter thermal network models, coupled with electricity generation models for photovoltaics and daylighting models. Prototypes for innovative building envelope concepts will be tested in a large scale combined solar simulator environmental chamber laboratory. Advanced active building envelope prototypes developed under objective 1 will be used in a test-room specially constructed to test control strategies under objective 2; this test-room will be utilized to test combinations of active and passive thermal storage systems integrated in its envelope. Model-based control strategies will be developed and validated experimentally under typical simulated weather profiles. Objective 3 involves primarily building cluster energy simulation models and studies to develop optimal energy design concepts that integrate the outcomes of work from objectives 1 and 2. Major expected outcomes of the proposed research include new knowledge on the performance of advanced energy positive building systems that integrate solar energy utilization, active building envelopes and optimal operation, and mathematical models of appropriate resolution for efficient predictive operation of high performance building clusters. This knowledge, models and tools will facilitate the design of high performance net-zero energy buildings and communities.

拟议研究计划的长期目标是研究建筑物和建筑群的最佳能源性能的途径，将完全集成的太阳能系统的现场发电与热能储存、能源效率措施和最佳控制相结合。目标如下： 1. 研究和开发先进的建筑围护系统，该系统结合了多种功能，以降低成本，同时最大限度地提高能源效率，例如开窗系统，半透明的光伏层可以在传输日光的同时发电，还可能产生有用的热量。 2. 研究和开发预测控制策略，通过控制主动围护系统（例如遮阳和采光装置）来优化太阳能增益利用率，以减少电力峰值需求，同时实现良好的舒适度。 3. 为建筑群或社区开发综合能源设计和控制概念，以便最佳地确定实现净零能源的途径，同时对电网需求状况产生可预测的影响。 与第一个目标相关的工作将首先探索不同立面概念的潜在能源性能，这些概念通过利用几乎全光谱的太阳光来发电，而日光和其余的有用热将是有前景的配置。通过使用集总参数热网络模型的综合能源模拟以及光伏发电模型和采光模型进行研究，创新建筑围护结构概念的原型将在大型组合太阳能模拟器环境室实验室中进行测试。根据目标 1 开发的原型将用于专门为测试目标 2 下的控制策略而建造的测试室；该测试室将用于测试集成在其外壳中的基于模型的控制策略的主动和被动蓄热系统的组合。将在典型的模拟天气情况下进行实验开发和验证，目标 3 主要涉及建立集群能源模拟模型和研究，以开发整合目标 1 和 2 工作成果的最佳能源设计概念。 拟议研究的主要预期成果包括关于先进能源积极建筑系统性能的新知识，该系统集成了太阳能利用、主动建筑围护结构和优化操作，以及高性能高效建筑群的有效预测操作的适当分辨率的数学模型。知识、模型和工具将促进高性能净零能耗建筑和社区的设计。
