从2000年开始，西门子决定对其设在哥本哈根附近巴勒鲁普的总部进行现代化改装。最初计划对原有办公大楼进行翻新改造，因项目预算经评估后发现改造成本太贵，于是公司很快决定采取B计划，即重建一栋全新的办公大楼。2014年，西门子新建总部采用了最新的西门子技术，令这栋建筑成为了西门子公司的最佳技术代言。开阔的中庭采光解决方案采用了六排威卢克斯VMS模块化智能天窗系统，保证了充足的采光，使其空间明亮宜人。

During the 00’ies the renowned German engineering company, Siemens, decided they needed to modernize their Head office in ballerup outside copenhagen. initially the plan was to refurbish the existing office building, but the project came out too expensive and the company soon turned to plan b, an entirely new building. So in 2014 the new Siemens Head office was inaugurated with all the latest Siemens technology, making the building a living showcase for
the company. The large atrium ridgelight solution consists of six rows of VELUX modular Skylights which ensures substantial amounts of daylight resulting in a bright and pleasant space.

丹麦西门子传媒总监John Finnich Pedersen表示，因西门子一直致力于可持续能源解决方案，所以新总部将所有最新的西门子技术集于一身，并在设计之初就考虑如何降低及减少能源的使用，将更多的阳光引入办公空间，同时做到光热可控，从而为员工带来更健康舒适的办公环境。这栋新办公楼完全满足了现代建筑的全部要求，因而也成为西门子集团内部的指路明灯。最终西门子总部获得了LEED认证的“金级”奖。

“It’s more like a mind-set”, explains Siemens danish director of communication, John Finnich pedersen. “We want to be as energy efficient as possible in the way we work.”John Finnich pedersen is proud of the way the new Siemens Head office has accumulated all the latest Siemens technology in one single building, but also how the strive for sustainable energy solutions has made this facility a kind of beacon within the company. “Our building is only one of a few that are LEEd certified. We have achieved the second highest rating, which is called ‘gold’. it supports the entire idea, that we should use as little energy as possible in our building. With this new office facility Siemens has fulfilled all its demands in terms of how a modern building should work.”

自然采光帮助西门子获得LEED认证
Documenting the daylight effect helped Siemens achieve LEEd certification

获得LEED金级认证，代表了办公楼室内环境和能源方面的领先地位。威卢克斯集团可持续建筑设计首席专家Lone Feifer女士认为，在规划新的建筑设计时，美国认证系统是极好的参考。通常来讲，这是一种可以确保建筑质量的方式。认证基于五项评估，分别是选址、水消耗、能源消耗、材料和资源、以及室内气候。由于需要评估更大范围内的可持续性，该系统将促使建造者和建筑师进行更广泛的思考。

LEEd stands for Leadership in Environmental and Energy design. According to Lone Feifer, the leading expert at the VELUX Group on sustainable living in buildings, the American certification system can be a great asset, when planning a new building design. “Generally it’s a way to ensure the quality of the building. The certification is based on five categories, which is about location, water consumption, energy consumption, materials and resources as well as the indoor climate. The system forces the builder and the architect to think more widely, since the sustainability is being assessed on a bigger scale”, says Lone Feifer.

▼ 自然采光，Natural sunlighting

上述参数之一涉及到办公楼内的自然采光。虽然要预知照明效果很难，为了帮助达成最佳自然采光效果，项目设计使用了威卢克斯集团研发的一款自然采光模拟分析软件。此软件可以用来模拟分析威卢克斯VMS天窗诸如建筑采光、节能和室内气候参数等，并最终准确的计算分析出室内自然采光率。使用这款软件计算的结果表明，VMS各项指标都相当出色，因而可以帮助建筑实现健康环境及节能目标并获得认证。

One of these parameters involves the volume of daylight in the building. it is difficult to predict the lighting effect in advance, however the VELUX Group has a tool that will do just that. “VELUX modular Skylights can help achieve the goals and support a certification. To help document the effect, we have developed a number of VELUX building Simulation Tools, which can be used to simulate the impact of VELUX modular Skylights. it’s important, because it is this form of simulating daylight, energy and indoor climate that in the end will document the significance of our modules.”

采光情况 Daylight Documentation

为了确定采光情况，使用VELUX Daylight Visualizer可视化自然采光分析软件，预先对建筑设计方案进行了测试。测试结果在帮助西门子安排其室内布景的同时，还表明此结构是丹麦已建成的办公楼中采光情况最好的建筑物之一。

To determine the influx of daylight, the building design was tested in advance with VELUX daylight Visualizer. While the result helped Siemens arrange the interior, it also revealed the structure to have one of the highest daylight factors ever to be registered in a danish office building.

温度控制 Heat control

为了评估已完工建筑的室内气候，还使用了威卢克斯开发的EIC能源与室内气候可视化软件，预先对该项目进行了测试。根据测试结果，西门子为所有VMS模块化天窗选择了配套的隐藏式白色遮阳帘。隐藏式遮阳帘根据温度和日光射入量反应，由 WindowMaster ® 系统自动控制，有效避免了建筑中庭过热或过亮。

能源效率 Energy efficiency

窗体框架结构使用了顶级新型复合材料，经高强挤压复合成型，可有效预防冷桥，并确保U值处于极低水平。窗体采用玻璃纤维、聚氨酯及树脂等多种复合材料挤压成型，具备卓越的强度和绝佳的保温性，并实现了低导热系数。预防冷桥是产品质量的决定因素之一，也是西门子在巴勒鲁普新总部大楼选择威卢克斯VMS商用天窗系统的重要原因之一。

The composite material used for framing protects against cold bridging and ensures a very low U-value. The low thermal conductivity is achieved, using a mold of pultruded fiberglass and polyurethane. The protection against cold bridging is a defining quality of the product and was one of the important reasons for choosing VELUX modular Skylights in ballerup.

在追求卓越能源效率之后，紧接着的是对充足光线的需求。这是一栋内庭式建筑，通常情况下，内朝向空间受到的日照总是少于外朝向空间，因此需要计算并测试内部中庭的日光照射量。该项目最终采用了228 樘威卢克斯VMS商用天窗，建造了一个拥有充足阳光和可直接仰视天空的特色室内广场。项目经理Palle Thusholt介绍道：“我们选择威卢克斯与诺曼福斯特事务所共同研发的VMS模块化天窗系统，是因为他们的产品非常激动人心。产品冷桥热量流失极少，冷桥保温处理得相当不错，远胜其它产品。最重要的是，它具有非常前瞻的能源特性。”

The pursuit of superior energy efficiency was followed by a demand for plenty of daylight. Siemens always wanted their building to be as bright as possible, and according to project manager palle Thusholt from kpc københavn A/S that meant a lot of testing and simulation. “It’s an atrium-house, and those spaces, which face towards the centre, will always have less daylight than those, facing outward. That is why calculations were carried out to test the amount of daylight coming in”, he says.
in the end no less than 228 VELUX modular Skylights were included in the project, creating a proper indoor plaza with plenty of sunlight and a direct view to the sky above. The reason VELUX modular Skylights was chosen for this project, explains palle Thusholt, was not only that it represented something new and inspiring. First of all it had some very promising energy properties. “We chose VELUX, because they came with an exciting product. it was newly developed and had very little cold bridging. The insulation against cold bridging looked to be reasonably good and came out better than its competitors.”

没有人会比西门子不动产部项目经理 Michael Gøtz更了解这座建筑的运行状态。在施工过程中，他负责监督建筑中所有最新技术的实施，其中包括西门子自己的绿色建筑监控系统，该系统直观地显示出此建筑如何节约了能源。有了这个系统，建筑使用者可以监控这栋建筑中的所有资源，观察它们如何被消耗。当耗水量上升时，该系统将告诉我们到底上升了多少，以及是哪里上升了，使用者可以对此采取相应行动。西门子不动产部项目经理 Michael Gøtz表示：“自然采光是获得LEED认证的核心部分。正如我们使用绿色建筑监控系统来记录结果一样，威卢克斯VMS天窗使建筑舒适且具有可持续性。它告诉我们，设计一座明亮的建筑并同时保持可持续发展是有可能的，VMS天窗系统是通往可持续发展之路重要部分。

no one is closer to the operating status of this building than project manager michael Gøtz of Siemens real-Estate. during construction he supervised the implementation of all the latest technology into the building, including Siemens own Green building monitor system, which visualizes how the building saves energy. “With this system, we can monitor all resources in the building, and how they are consumed. if the water consumption goes up, the system will tell us exactly how much and where it happens. And we can act on it”, he explains. The VELUX modular Skylights are controlled by a Windowmaster® system and are not a part of the monitoring system, however as michael Gøtz underlines, the skylights are very much a part of the overall concept. “Daylight is a central part of being LEEd-certified. in the same way as we use our Green building monitor system to document the results, the skylights are there to make the building pleasant and sustainable. it tells us that it is possible to design a bright building and remain sustainable at the same time.”

白色确保充足的日光和最佳的隔热保护
The white colour ensures plenty of daylight and optimal heat protection

228樘威卢克斯VMS商用天窗都配有一体化集成的白色遮阳帘，相比于深色面料，白色遮阳帘透光率更高，当天窗遮阳帘关闭时不仅能防止眩光，还保持了良好的天窗采光效果。遮阳帘的主要目的是保护西门子总部避免受到过多来自太阳的辐射热，尤其是在夏季，这么大尺度的建筑中庭，暴露在阳光的炙烤之下，如果没有遮阳帘，就会有大量的辐射热传递进来。白色，是遮阳帘的理想颜色，因为该颜色能更有效地反射太阳热能。用术语来说，相对于黑色和灰色0.15的太阳得热因子（g 值），白色遮阳帘的g 值只有 0.13。当然，冬天时的作用正好相反。在白天，西门子总部的中庭天窗必然会成为一个非常有用的加热“装置”，可提供免费的太阳能来给建筑升温，同时降低能源消费总量。

All 228 VELUX modular Skylights are fitted with fully integrated, white roller blinds. contrary to darker fabrics, white blinds has a much higher light transmittance, providing more daylight to the interior even when the blinds are closed. in other words, the blinds will protect against glare, but not inhibit the lighting effect of the skylights. The main purpose of the blinds at Siemens Head office is to protect against excessive heating from the sun. Especially in the summertime the large atrium would be exposed due to the shear size of the solution. The white blinds are the optimal choice for heat protection, since the colour reflects solar energy more efficiently. in technical terms the Solar Energy Transmittance (g-value) of white roller blinds are only 0.13 compared to 0.15 for black and grey. Of course when the winter sets in the opposite is true. The large skylight at Siemens Head office will certainly become a very useful heating “apparatus” during the day, providing free solar heat to the building while lowering the total energy consumption.
