架构师提供的文本描述。得克萨斯大学奥斯汀分校的新文科大楼是校园内最大的学院的多功能学术大楼，年招生人数超过15，000人。由于以前的部门分散在整个校园，一座新的建筑对学院持续的成功和声誉至关重要。

Text description provided by the architects. The new Liberal Arts Building at the University of Texas at Austin is a multifunctional academic building for the largest college on campus with an annual enrollment of over 15,000 students. With departments previously scattered throughout campus, a new building was vital to the ongoing success and reputation of the College.

然而，由于缺乏传统渠道的建设资金，学院计划通过削减项目来自筹资金。通过评估效率和灵活性，该项目的实施方式减少了成本，缩短了施工时间，同时仍使用了最高质量的建筑材料。在68%的效率，该建筑产生了20%的可用空间比规划，并交付了1500万美元的预算和提前一个学期的计划。

However, due to a lack of construction funding from customary channels, the College had planned to self-fund the project through program cuts. By evaluating efficiencies and flexibility, the project was implemented in a way that reduced costs and decreased construction time while still using the highest quality building materials. At 68 percent efficiency, the building yielded 20 percent more useable space than programmed, and was delivered $15,000,000 under budget and a semester ahead of schedule.

该大楼通过整合正式和非正式的会议空间、提供各部门成员之间“碰撞”机会的战略流通以及房间和楼层之间的视觉联系来促进协作。利用邻近的学生活动中心(SAC)中未使用的空间，一座架空桥梁在物理上连接CLA和SAC，使学生能够进入其上两层，这是学院额外的项目空间。

The building facilitates collaboration through the integration of both formal and informal meeting spaces, strategic circulation that provides opportunities for “collision” between members of various departments, and visual connections between rooms and floors. Leveraging unused space in the adjacent Student Activity Center (SAC), a sky bridge physically connects the CLA to SAC, giving students access to its upper two floors, which house additional program space for the College.

教室分布在每一层，学术办公室环绕整个大楼，以便学生和教师占用相同的空间。这座建筑被设想有100年的寿命，行政和教师空间的设计是为了随着时间的推移而对学院的需求进行改造和重组。周边海湾是悬臂，以提供灵活的平面图，同时减少柱和码头。位于这些地区的玻璃可拆卸隔板将日光传输到室内空间，也可以重新配置。

Classrooms are distributed on every floor, and academic offices circumnavigate the entire building so that students and faculty occupy the same space. The building is conceived to have a 100+ year lifespan with administrative and faculty spaces designed to be retrofitted and reorganized as the college’s needs change over time. Perimeter bays are cantilevered to provide floor plan flexibility while reducing columns and piers. Glazed demountable partitions located throughout these areas transmit daylight to interior spaces and can also be reconfigured.

通过使用创新技术和高效的机电系统，该建筑的能耗比一座符合基准代码的建筑少48%。能源效率战略，除其他外，包括使用主动冷却梁机械系统，室内采光，和减少太阳能热增益。在冷梁系统中，校园中央厂房的冷水首先用于建筑核心内的常规机械系统。

Through the use of innovative technologies and highly efficient mechanical and electrical systems, the building uses 48% less energy than a baseline code-compliant building. Energy efficiency strategies, among others, include the use of active chilled beam mechanical systems, interior daylighting, and mitigation of solar heat gain. Within the chilled beam system, chilled water from the campus central plant is first used for conventional mechanical systems within the building core.

 Typical Floor Plan

加热后的冷却水-适合于冷却梁-然后通过位于周边教职员工办公室的冷却横梁进行流通，这样就可以在提供个人温度控制的同时，以免费的方式对教职员办公室进行冷却。这种冷却水的二次使用会将温度提高到最佳的回程水平。这一战略总体上使用了较少的冷水，在校园中央工厂为未来建筑降温留下了更多的容量。

The warmed chilled water—appropriate for chilled beams—is then circulated through chilled beams located in the perimeter faculty offices, which allows faculty offices to be cooled at no cost while providing individual temperature control. This secondary use of chilled water raises the temperature to the optimum level for return. This strategy uses less chilled water overall, leaving additional capacity at the campus central plant for cooling future buildings.

外保温玻璃与陶瓷熔块允许太阳能控制。水平的外部防晒霜和室内遮光架与可操作的滚筒遮阳被整合到这个玻璃系统中，控制白天和全年的日光和热量。全高度的兵马俑板提供垂直太阳能遮阳相邻的玻璃，以及高度绝缘的备份墙后面。

Exterior insulated glazing units with ceramic fritting allow for solar control. Horizontal exterior sunscreens and interior light shelves with operable roller shades are integrated into this glazing system, controlling daylight and heat gain throughout the day and year-round. Full-height terracotta panels provide vertical solar shading to adjacent glazing as well as to a highly insulated backup wall behind.

雨屏允许这种后备墙和兵马俑装配之间的自然对流，进一步减少了白天太阳热量的增加。这种高效率的玻璃窗、防晒霜和高R值外墙的结合使得设计能够在建筑周边实现55%的玻璃化，同时提供一个超过当地建筑规范的整体围护结构。

The rainscreen allows natural convection between this backup wall and the terracotta assembly, further reducing solar heat gain throughout the day. This combination of high-efficiency glazing, sunscreens, and high R-value exterior walls allow the design to achieve fifty-five percent glazing around the building perimeter while providing an overall envelope that exceeds local building codes.

教职员办公室的大部分工作时间都没有人工照明，额外的受控制的日光穿透了内部被占领的区域。一个庞大的项目和紧凑的场地需要仔细考虑建筑的聚集，并需要一个广泛的，方形的足迹。该设计在建筑地板上加入了大凹槽，以使日光能更深入地渗透到建筑物中，并提供更多的外部景观。楼梯井是滑雪的，在一个宽的地板内形成一个发光的核心。

Faculty offices operate without artificial lighting for the majority of operating hours and additional controlled daylight penetrates into interior occupied zones. A substantial program and tight site required careful consideration for building massing and necessitated a broad, square-shaped footprint. The design incorporates large notches in the building floor plates to allow daylight to penetrate further into the building and afford additional views outside. Stairwells are skylit, creating a luminous core within a broad floor plate.

CLA通过它的三方划分以及材料和颜色调色板来参考历史的校园建筑。陶土的雨幕与其他校园建筑使用的历史陶器有关，其颜色与校园内的石灰石相匹配。从历史悠久的校园建筑中发现的色彩缤纷的彩釉中，衍生出了一种在相邻的玻璃上进行陶瓷烘焙的调色板。

CLA references historical campus buildings through its tripartite division as well as material and color palettes. The terracotta rainscreen relates to historical terracotta used by other campus buildings, with a color that matches the limestone also found throughout campus. A color palette for the ceramic fritting on adjacent glazing was derived from the colorful glazed soffits found on historical campus buildings.

CLA通过可持续的设计，最大限度地利用用户利益，重新定义了未来校园建筑的建设标准。此外，通过可持续设计的综合方法，该项目超越了LEED银的最初目标，而获得了LEED黄金认证。

CLA redefines the standard of future building construction on the campus through sustainable design and maximized user benefit. Additionally, through an integrated approach to sustainable design, the project surpassed its initial goal of LEED Silver, instead achieving LEED Gold certification.
