Theater & RESTAURANT

KGM was also responsible for the lighting of the Jersey Boys Theatre and the Grand Lux Café. (Other lighting design firms were responsible for additional restaurants at The Palazzo.) The target for the theater was 1.6 watts per sq ft, but no relamping was necessary because design started after the LEED process was already in progress. LED cove lights are used in the lobby and public areas outside doors of the performance venue, while linear fluorescent cove lights serve as emergency lighting. Recessed downlights and in-grade low-voltage uplights equipped with 37-WMR 16s were specified.

剧场&餐厅

KGM同时也负责泽西男孩剧场（Jersey Boys Theatre）以及Grand Lux咖啡馆的照明设计。剧场的目标功率密度为1.6W/sq ft，不过这部分并不需要替换光源，因为这部分的照明设计开始时LEED评价已经介入。大堂和室外的公共演出场地均采用了LED线槽灯，而线性的荧光灯作为应急照明。嵌入式灯具和低压埋地上照灯均选用了37W MR16灯杯。

Although it didn't factor into the LEED portion of the project, the Grand Lux Café had to meet a .9 watts per sq ft LPD under Las Vegas building code. The café is owned by the Cheesecake Factory and was originally designed under its corporate standard, which called for incandescent lamps. “It’s an old-style restaurant with lots of fixtures and the client wanted the ambiance to really stand out,” says van Koolbergen, who specified dimmable CFL lamps to help approximate the warmth of incandescent. The retrofit of the decorative fixtures allowed the restaurant to maintain the same look as all other Grand Lux Cafes.

虽然Grand Lux咖啡馆并不属于LEED评价范围，但仍需遵守拉斯维加斯建筑规范里的0.9 W/sq ft的功率密度。咖啡馆属于芝士蛋糕工厂旗下，其原先的设计只遵循了企业内部的规定，并选用了白炽灯光源。“这是一个传统风格的餐厅，有大量的装饰灯具，并且业主希望整体光环境看上去非常引人注目”Van Koolbergen说道，于是他选择了可调光的节能灯泡来替换，尽可能接近白炽灯所营造出的暖光效果。最终，餐厅的装饰灯替换光源的方案使得其与其他Grand Lux咖啡馆看上去并无差别。

DAYLIGHTING

In a city where indoor natural light is a rarity, The Palazzo atrium was outfitted with four massive skylights (one roughly 80-ftwide).

ETC, Middleton, WI, supplied the controls (the Unison system) for the atrium. The Unison system is programmed to save energy through occupancy sensing and daylight harvesting, helping the project earn one LEED point for lighting controls. The downlights run on several different circuits, so the number of circuits that are on can be reduced based on the natural light available.

自然采光

拉斯维加斯的建筑鲜有自然采光，The Palazzo的中庭却通过四个大型天窗引入了大量的自然光（每个天窗长度接近80英尺）。

ETC, Middleton, WI为中庭的控制系统提供支持。该系统通过感应器监测日光的变化，并通过程序控制来节能，该照明控制为LEED评价争取了一个得分项。下照灯被分配在数个回路中，可通过调节照明的回路总数来控制亮度。

“The aesthetic challenges area little different when lighting an interior that already has so much natural light,” says van Koolbergen. “You're no longer dealing with space as a box. In certain areas, you have counter the intensity of the natural light and balance it with uplighting and decorative features. At night, the lighting control system has to be balanced to maintain the proper footcandles on the ground to meet emergency standards, deemphasize the “balck holes” of the skylights and retain the monumental feeling of the architecture. A lot depended on the use of energy-efficient lamps and sources, and the control system with its dimming capacity.”

“对于一个拥有如此充足自然光的室内空间的照明设计的美学挑战是与众不同的，” Van Koolbergen说道“我们不再是对待一个盒子一般的空间。在某些区域，我们必须计算自然光的光照量，并将上照光和装饰灯具的光照与之平衡。在晚上，照明控制系统调节人工光，使之满足安全标准，弥补日光这部分的光照量并使建筑始终呈现宏伟壮观的景象。我们通过一系列措施来保证绿色低碳，诸如高效节能的光源、可调光的控制系统等。”

Despite the painstaking calculations that went into lamp redesign, van Koolbergen believes the true legacy of the project is that high-end lighting design can coexist with sustainability. “This project is a new benchmark for the industry. It demonstrates that the developer of a major upscale property-on the Strip or elsewhere-can maintain standards for quality, drama and experience and also be environmental good guys.”

除了重新设计节能光源带来的令人痛苦的庞大计算量，Van Koolbergen认为这个项目的宝贵经验在于说明了高端市场的照明设计可以兼顾可持续的设计理念。“这个设计对于整个行业具有里程碑的意义。它表明了高端物业的开发商在照明方面可以同时兼顾质量、戏剧效果、使用体验，同时还绿色环保。”
