Buildings currently account for over 40% of the total UK energy consumption and a similar percentage of the UK CO2 emissions. The energy used in buildings is largely required for creating a thermally and visually comfortable environment for building occupants. Glazed façades play an important role in determining a building's energy performance and are called upon to perform a range of, sometimes conflicting, functions. They are required to i) regulate heat transfer to and from the external environment by solar and long wave radiation, conduction and convection ii) allow transmittance natural daylight to provide interior illumination, reducing the need for supplementary electric lighting and to provide an aesthetic function, both in terms of their influence on building appearance and providing occupants a visual link to the external environment. Improving fenestration energy performance can make a significant contribution to reducing building energy loads. It is reported that optimal glazing design could reduce residential building energy consumption by 10-50% in most climates, while for commercial, institutional and industrial buildings, a properly specified fenestration system could reduce lighting and air-conditioning costs by 10-40%.We are going to carry out a holistic approach to develop advanced façades technologies to achieve building energy demand reduction goals. This compliments Centre for Research into Energy Demand Solutions (CREDS) objectives of energy demand within the 'building' & 'heat decarbonisation' theme of the centre. Low cost optical components will be designed and integrated into conventional double glazing, which will significantly increase the thermal resistance of the window, provide control of the solar heat gain, and enable windows to perform better than walls on a yearly basis in terms of their net energy balance. Building energy loads will be reduced significantly while providing comfortable daylight. The target is that when integrated in a typical commercial building the novel glazing façade system will provide comfortable annual daylight levels achieving over a 20% reduction in annual artificial lighting energy consumption, reduce space heating demand by over 30% in the heating season and cooling load by 20% in Summer. The integration in a façade system of active solar energy technologies with better performing windows may potentially lead commercial buildings to be a negative energy load on an annual basis.

目前，建筑物占英国能源消耗总量的40%以上，占英国二氧化碳排放量的相似比例。建筑物中使用的能源主要用于为建筑物居住者创造热舒适和视觉舒适的环境。玻璃幕墙在确定建筑物的能源性能方面发挥着重要作用，并被要求执行一系列有时相互冲突的功能。它们需要i）通过太阳能和长波辐射、传导和对流调节与外部环境的热传递ii）允许自然日光透射以提供内部照明，减少对补充电力照明的需求并提供美学功能，无论是在它们对建筑外观的影响方面，还是为居住者提供与外部环境的视觉链接。提高开窗节能性能可以为减少建筑物能源负荷做出重大贡献。据报道，在大多数气候条件下，优化的玻璃窗设计可以使住宅建筑能耗降低10-50%，而对于商业、机构和工业建筑，适当指定的开窗系统可以使照明和空调成本降低10- 40%。我们将采取整体方法开发先进的立面技术，以实现建筑能源需求减少目标。这是对能源需求解决方案研究中心（CREDS）在该中心的“建筑”和“热脱碳”主题中的能源需求目标的补充。低成本的光学元件将被设计并集成到传统的双层玻璃中，这将显著增加窗户的热阻，提供对太阳能热增益的控制，并使窗户在净能量平衡方面每年比墙壁表现得更好。建筑物的能源负荷将大大减少，同时提供舒适的日光。其目标是，当集成在典型的商业建筑中时，新型玻璃幕墙系统将提供舒适的年度日光水平，实现年度人工照明能耗降低20%以上，在供暖季节将空间供暖需求降低30%以上，在夏季将制冷负荷降低20%。主动太阳能技术与性能更好的窗户的立面系统的集成可能会导致商业建筑每年成为负能源负荷。
