新加坡高层办公方案，追求能源产量最大化，消耗最小化

作为新加坡一座面向未来的高层办公楼的竞赛方案的一部分，思锐建筑事务所提出了“tower of tables”方案，可以应对当前气候挑战。

为回应其热带环境，该项目将塔楼重新构想为一系列堆叠的凉亭，将四到六层的工作区与周围的景观露台分隔开，并促进了现代办公的协作性。

塔楼还配有一个灵活的平台，其包括一个带四个圆形亭子的中央庭院，这些可用于会议或作为休息空间。

as part of an invited competition proposal for a future-oriented high-rise office in singapore, serie architects has proposed ‘tower of tables’ — an architectural reaction to current climatic challenges. responding to its tropical context, the project re-imagines the tower as a series of stacked pavilions, compartmentalizing four to six storey workspace communities with surrounding landscape terraces and facilitating the collaborative nature of contemporary office-based work. the tower is complemented with a flexible podium that includes a central courtyard with four circular pavilions. these can be used for meetings or as breakout spaces.

思锐建筑事务所表示，该方案通过解决建筑，能源消耗和能源生产等问题来减少碳排放。

设计团队说道：“这三种策略合在一起，每平方米可以减少60%以上的碳排放。” ‘采用层压胶合实木(Mass Engineered Timber)，可使整体内含的碳排放可以减少50%。

舒适性和能源设计方面的创新可将办公场所的电能需求减少30％，而现场的光伏发电可以产生建筑20%的电能需求。”

serie architects says that the proposal reduces carbon emissions by addressing construction, energy consumption, and energy generation. ‘taken together the three strategies reduce carbon emissions per m2 by over 60%,’ the design team explains. ‘with mass-engineered timber (MET), the total embodied carbon emission can be reduced by 50%. innovation in comfort and energy design can reduce electrical energy demand of the office spaces by 30% while on-site photovoltaics can produce approximately 20% of the building’s electrical energy demand.’

塔楼的几何造型由其创新的结构概念定义。建筑师继续说道：“塔楼的核心筒和凉亭的结构框架都是钢制的，而中间楼层则是钢和木材的混合体。”

“采用层压胶合实木取代中间四层，从而实现了一座碳中和高层建筑。”

the tower’s table form is defined by its innovative structural concept. ‘the tower core and structural frame of each pavilion is made of steel while intermediate floors are constructed of a hybrid of steel and timber,’ the architects continue. ‘by replacing four intermediate floors with met floorplates, the total embodied carbon per table is about 0 kg per m2 of office area, resulting in a carbon neutral high-rise.’

立面的设计最大化了日光，同时减少了眩光和太阳热能。

同时，高能效的“自适应冷却”取代了传统的空调。与相同规模的典型建筑相比，用电量减少了50％以上。

除了使能源消耗最小化，该方案还将能源产量最大化，约占总电力需求的20%。所有屋面都安装了光伏电池，并嵌入到为建筑玻璃罩遮阴的板层中。

the design of the facade maximizes daylight, while minimizing glare and solar heat gain. meanwhile, energy efficient ‘adaptive cooling’ replaces conventional air conditioning. the result is a more than 50% reduction in electrical use compared to a typical building of the same size. as well as minimizing energy consumption, the proposal maximizes energy production with about 20% of the total electrical energy demand harvested on site. photovoltaic cells are placed on all roof surfaces and embedded into the lamella that shade the building’s glazing.

思锐建筑事务所表示，该项目旨在创造充满活力的非正式工作空间，以适应当代和新兴的办公场所工作模式。

“通过高效的服务设计，可以实现宽敞灵活的布局，该项目可满足未来可知的工作方式，同时代表着热带地区现代高层建筑的新“形象”。

with an emphasis on creating lively informal workspaces, the project accommodates contemporary and emerging models of office work,’ serie architects explains. ‘generous and flexible layouts achieved through the efficient design of services mean that the project also anticipates ways of working not yet known. its considered response to climate is inherent to the architecture. neither appendage nor afterthought, material and energy flows are placed at the fore. the result is a new ‘image’ of the contemporary high-rise in the tropics.’
