目的
电气照明在商业建筑的能源消耗中占很大份额。日光的利用可以显著帮助减少对人工照明的需求，提高工人的生产力和客户的满意度，从而提高销售额。然而，过度使用玻璃窗和缺乏照明控制可能会大大增加加热和冷却的能量需求，并导致不希望的眩光效果。因此，优化外部玻璃的尺寸、位置和材料，加上导流板和动态人工照明，可以成为可持续低能耗建筑设计的关键方面。本文的目的是分析日光的潜力和能源性能的大厅式商业建筑，位于芬兰的寒冷气候，利用不同的天窗，窗户和照明控制的组合。
设计/方法/方式
作者使用计算机模拟来估计单层商业建筑的日光和能源性能，这些建筑与天窗和窗户的各种组合有关，这些天窗和窗户具有可变的玻璃材料、光偏转器和分区照明控制。
结果
结果表明，在使用多区域照明控制的玻璃天窗和墙窗的情况下，电灯节能潜力从微不足道的1.9%到显著的58.6%不等。在单区域照明控制的情况下，总输送能量的范围在1.5%和21.2%之间，在多区域控制的情况下，总输送能量的范围在4.5%和4.5%之间。一次能源消耗的最大降幅为单区域2.2%，多区域照明控制17.6%。该研究强调了使用日光照明策略的电灯节能的巨大潜力，包括控制眩光和内部增益的直接太阳能接入，可以超过50%。
独创性/价值
这项研究结合了准确的日光和能源评估的商业大厅建筑在寒冷的气候地区与多种设计变化。这项工作的新奇在于考虑了计算中的内部元素，搁板和偏转器。这是通过结合使用经过验证的模拟平台进行详细的年度采光和电气照明计算（Radiance和Daysim）和能源分析（IDA-ICE，Equa Simulation AB）而实现的。这种方法可以获得可靠的评估，在建筑物中使用自然光源的潜力。
Purpose
Electric lighting accounts for a large share of energy consumption in commercial buildings. Utilization of daylight can significantly help to reduce the need for artificial lighting, increase workers productivity, customers’ satisfaction and consequently improve sales. However, excessive use of glazing and absence of lighting controls can contribute greatly to higher energy need for heating and cooling and cause undesired glare effects. Thus, optimizing the size, position and materials of external glazing, with the addition of deflectors and dynamic artificial lighting, can become key aspects in the design of sustainable low energy buildings. The purpose of this paper is to analyze daylight potential and energy performance of a hall-type commercial building, situated in the cold climate of Finland, by utilizing different combinations of skylights, windows and lighting controls.
Design/methodology/approach
The authors have used computer simulations to estimate daylight and energy performance of a single floor commercial building in relation to various combinations of skylights and windows with variable glazing materials, light deflectors and zonal lighting controls.
Findings
The results show that electric light energy saving potential ranges from a negligible 1.9 percent to a significant 58.6 percent in the case of glass skylights and wall windows using multi-zone lighting control. Total delivered energy ranges between increase of 1.5 and 21.2 percent in the cases with single zone lighting control and between decrease of 4.5 percent and increase of 4.5 percent in the cases with multi-zone control. The highest decrease in primary energy consumption was 2.2 percent for single zone and 17.6 percent for multi-zone lighting control. The research underlines the significant potential of electric light energy savings using daylighting strategies that, including the control of direct solar access for glare and internal gains, can be more than 50 percent.
Originality/value
This research combines accurate daylight and energy assessment for commercial hall buildings based in cold climate region with multiple design variations. The novelty of this work is the consideration of interior elements, shelves and deflectors, in the calculations. This is made possible through the combined use of validated simulation platforms for detailed annual daylighting and electric lighting calculation (Radiance and Daysim) and energy analysis (IDA-ICE, Equa Simulation AB). This method allows to obtain a reliable assessment of the potential of using natural light sources in buildings.
