该空间是功能和服务不同的目的：目的是创造一个多价布局，以适应不同的市场需求。顶层是专门为三井电梯(一家电梯公司)的总部，零售的底层和几个办公楼层之间提供一个开放的规划空间，可以被布置成不同的配置。这座建筑需要有成本效益。对此，RAA努力寻找聪明的想法，使用成本效益和免维护的材料，如玻璃钢筋混凝土面板的外观。

The space is functional and serves different purposes: the aim is to create a polyvalent layout to accommodate different market needs. The top floors are dedicated to the headquarters of Mitsulift (an elevator company), the ground floor for retail and a few office floors in between offer an open plan space that can be layout into different configurations. The building needed to be cost efficient. For this, RAA endeavored to find smart ideas for using cost efficient and maintenance-free materials, such as GRC (Glass Reinforced Concrete) panels for the façade.

一座高效、可持续发展的建筑是指从内部有一个经过仔细思考的空间，而不仅仅是外表看起来很好的建筑：外墙是内部效率的外部翻译，而不仅仅是一个审美框架。

A building that works efficiently and in a sustainable manner is one that has a carefully thought-out space from the inside, not that just looks good from the outside: the façade is an external translation of the internal efficiency not just an aesthetic frame.

 Elevations

RAA主要关注的是用户的生活质量和建筑效率，尽量减少直接阳光和热量的摄入。为优化这一效果，提高了天花板的高度，并创建了高而深的凹缝窗，使开口位于东侧和西面的阴凉处。这一比例的高窗户提供了更自然，均匀的光线进入办公室的深处。

RAA main concern is the living quality of the users and the efficiency of the construction by minimizing direct sunlight and heat intake. To optimize this effect the ceiling height was raised, and high, deep recessed slit windows were created so that the openings are in the shade on the east and west. This proportion of high windows gives more natural, homogenized light into the deep end of the office.

被动绿

Passive green

这些窗户无法操作，以提高外墙的隔热性能，使其受到热、声和尘的污染。空气交换是通过过滤热回收机，从而尽量减少热消耗。该建筑位于高速公路上，该理念易于实施，其结果是城市环境中的空间质量更好。

The windows are not operable in order to enhance the insulation properties of the façade in terms of thermal, sound and dust pollution. The air exchange is through filtered heat recovery machines, hence minimizes thermal consumption. The building being located on a highway, the idea was easy to implement; the result is a better quality of spaces in urban environments.

生态解决方案并不总是由技术驱动的。太阳在黎巴嫩极为有效：它是一种可利用的能源。建筑师必须迎合当地的气候，适应当地的生活方式和文化。其他被动方法是利用热质量在白天吸收热量，并在夜间释放热量。高效的技术系统，如太阳能热水供暖、VRV空调、LED和荧光灯照明、能量回收和变速电梯也被用于三升总部大楼。

Ecological solutions are not always technologically driven. Sun is extremely efficient in Lebanon: it is an available energy. The architect must cater to the local climate and adapt to local lifestyle and culture. Other passive approach is the usage of thermal mass to absorb heat during the day and release it at night. Efficient technological systems such as solar heating for hot water, VRV air-conditioning machines, LED and fluorescent lighting, energy recovery, and variable speed elevators are also used in Mitsulift Headquarters building.
