这是由西班牙建筑设计公司LVA设计的起伏式屋顶的希思罗机场2号航站楼，这一项目给旅客提供了舒适方便的机场候机环境和便捷安全的登机程序。起伏的屋顶设计分为三个区域：检查，安全，和离开。使建筑的导航能力更加的便捷和准确，而且在项目程序上，也体现了支持终端的可持续发展特性。

这是英国历史上的第一次，机场的乘客可以直接进入登机口，而且旁边就是零售商店和餐饮设施。在老的二号航站楼的基础上建立的新航站楼，设计师在视觉上给了我们一个挥舞着的起伏屋顶结构，并巧妙的将自然光引入室内。玻璃面板，北部的铝固体管，和金属百叶窗，都可以将太阳光漫反射。一个精致巧妙的变色LED系统，逐步调整整个天顶，模仿自然光线运动，帮助人们应对国际旅行中的方向迷失。垂直面向北部的窗户提供了人们天空的视图，这在大多数机场都是一次非同寻常的经历。东部和西部的大型悬崖材质也减少了建筑的太阳能增益。

整个设计尽量提高能源的利用率（超过%90的原始建筑材料都被重新使用），这样就可以减少终端二氧化碳的排放量，据估算，共计减少二氧化碳排放量40%。光伏板安装在南部立面。设计还设法收集雨水，并进行二次利用。终端设计和施工的一个主要的特点就是使用预制模块，包括机械和电气设备。这些设备非常容易在现场安装，建筑的形式是一个简单而大胆的重复，创造出了一个真正大气独特的机场建筑。

Seeking to reinstate the excitement that used to be associated with international travel， the nearly completed terminal 2 at heathrow airport is designed by spanish firm luis vidal + architects (LVA) to offer passengers a hassle-free experience. traversing to and from departure gates， a modular， undulating roof maps people's journey across the terminal into three zones: check in， security and departures， making navigation through the building easier and more instinctual， as well as programmatically supporting the terminal's sustainable design features.
For the first time in the UK， airport passengers will have immediate access to departure gates that are located within sight of retail and catering facilities. built on the footprint of the old terminal 2， the architects designed the ocular， waving roof structure to cleverly filter natural light into the interior volume. the diffused light is reflected from north facing glazed panels with aluminum solid tubes and metallic louvres. a subtle， color-changing LED system gradually adjusts throughout the day mimicking the natural light movements outside - helping people to deal with the disorientation of international travel. vertical north facing windows provide views to the sky above， an uncommon experience in most airports， while large overhangs provide shading on the east and west facades， reducing the building's solar gain.
Designed to be as energy efficient as possible (over 90 percent of the original structure's materials were reused) the aim is to reduce the terminal's CO2 emissions by 40 percent. photovoltaic panels are installed on the southern facade and the design incorporates rainwater collection to be used for grey water. one of the main technical features of the terminal’s design and construction， is the use of prefabricated modules that contain the mechanical and electrical equipment. easily assembled on site， the form is a simplistic but bold repetition creating a truly unique airport experience.
