架构师提供的文本描述。20街的办公室是加州圣塔莫尼卡三家设计公司的创意工作室。他们包括大约6800 SF的演播室空间在一个两层，加上阁楼，建筑。它们位于美国一个顶级的“绿色”城市中，占地7500平方英尺。圣莫尼卡凭借其广泛的绿色建筑计划和公共政策赢得了这一排名。然而，在圣莫尼卡，可持续发展计划的重要性并不仅限于政策；一个广泛的关注环境的公民和企业主网络(20街办事处的建筑师也是其中之一)推动了这一进程的向前发展。在建筑设计和理论的最新发展轨迹上，该公司希望负责任地领导其同胞、同事和客户参与绿色建筑项目，在设计自己的办公室时也不例外，因为他们追求的是LEED-NC黄金评级。

Text description provided by the architects. The 20th Street Offices serve as creative working studios for three design firms in Santa Monica, California. They consist of approximately 6,800 sf of studio space in a two story, plus mezzanine, building. They are located on a 7,500 square foot lot in one of the United States top ‘green’ cities. Santa Monica earned this ranking with its extensive Green Building Program and public policies. However, the prominence of sustainable initiatives in Santa Monica doesn’t end with policy; an extensive network of environmentally conscious citizens and business owners, of which the architects of the 20th Street Offices are a member, propels it forward. It is the firm’s desire, along side of its latest trajectories in architectural design and theory, to responsibly lead its fellow citizens, colleagues, and clients in green building initiatives and made no exception when designing their own offices as they pursued a LEED-NC Gold rating.

除了建筑设计可以实现的自然系统的效率之外，第20街的办公室充斥着符合环保意识和符合LEED要求的能源效率、可再生能源、水效率、空气质量、再生材料和快速可再生资源的选择。

Beyond the efficiency of the natural systems that the architectural design could achieve alone, the 20th Street Offices are flooded with environmentally conscious and LEED compliant choices in energy efficiency, renewable energy, water efficiency, air quality, recycled materials and rapidly renewable resources.

20街的办公室实现了超过31%的年度能源使用和成本节约，12.5%的年能源使用是由屋顶和西高地的光伏电池板供电的。建筑师还通过购买相当于他们年能源使用量70%的“绿色标签”来参与推广和资助绿色能源。

The 20th Street Offices achieved over 31% savings in annual energy usage and costs and 12.5% of their annual energy usage is powered by photovoltaic panels on the roof and west elevation. The architect also participates in the promotion and funding of green power through purchasing the equivalent of 70% of their annual energy usage in ‘green tags’.

在像南加州这样的地方，水资源保护是至关重要的，第20街的办事处实现了超过47%的用水减少。虽然该项目最大限度地利用了超过分区标准的110%的开放空间，但为景观和绿色屋顶选择的植物都是耐旱的加州土著，需要较少的用水。灌溉系统是一个效率为90%的Drapp系统，由两个蒸散传感器控制，根据特定植物在各自微气候中的当前和预期天气条件限制用水。

In a place like Southern California where water conservation is critical, the 20th Street Offices achieved over 47% water use reduction. While the project maximized its open space 110% beyond the zoning code, the plants chosen for the landscape and green roof are all drought tolerant California natives, requiring less water usage. The irrigation is a dripp system with 90% efficiency and is controlled by two evapotranspiration sensors that limit water usage according to the particular plants’ needs in response to current and anticipatory weather conditions in their respective microclimates.

保存材料和资源是建筑师通过建筑采取的主动行动，并在入伙后得到维护。他们以循环再造的方式，将拆卸及建造中产生的废物中的84.6%转用于堆填区，并继续参与日常循环再造工作。20街办事处的材料成本中有30%以上用于回收内容的材料。另有2.6%的材料成本用于快速再生材料，并在磨坊上使用竹子。

Preserving materials and resources was an initiative of the architect through construction and has been maintained after occupancy. They diverted 84.6% of the waste produced from demolition and construction from landfills by recycling and continues to participate in routine recycling. Over 30% of the material costs for the 20th Street Offices were spent on materials with recycled content. Another 2.6% of the material costs went toward rapidly renewable material with the use of bamboo on the millwork.

建筑师为所有在第20街办事处工作的承包商编制了室内空气质量计划，以便在现场遵守。该文件旨在确保建筑期间的清洁空气质量，并要求所使用的每一种产品都必须是零噪音或低排放。在入伙前，当局与一名持牌第三者签订合约，以确保空气中没有有害粒子，并确保该大厦内的住户有清洁的室内空气质素。第20街办事处的目的是要创造一个健康的工作环境，既包括对居住者的影响，也包括对周围环境的影响。这些努力的一些成果是减少了42%的城市径流，其中95.6%在离开现场之前得到处理，75%以上的表面采用热岛减少战略，并通过新的公司奖励措施和获得自行车储存设施、淋浴设施、每天超过441次公共交通出行以及优先停放节油车辆和汽车池来促进替代交通。

The architects compiled an Indoor Air Quality Plan for all contractors working on the 20th Street Offices to comply with while onsite. The document served to ensure clean air quality during construction and required that every product used must be zero voc or low emitting. Prior to occupancy, a licensed third party was contracted to ensure that no harmful particulates were in the air and that the building had clean indoor air quality for its occupants. The 20th Street Offices intended to create a healthy working environment with regards to both the impact it has on its occupants as well as the one it has on its surrounding environment. Some results of these efforts were a 42% reduction in urban runoff of which 95.6% is treated before leaving the site, heat island reduction strategies for over 75% of surfaces and the promotion of alternative transportation through new company incentives and accessibility to bike storage, shower facilities, over 441 public transit trips per day and priority parking for fuel-efficient vehicles and carpools.

在第20街办事处的设计和施工中，每个符合环境意识和LEED标准的元素都已被纳入整个大楼的案例研究和标识方案，供游客、客户和居住者自己使用，作为一种教育工具和试验对象，以试验未来的绿色建筑产品和举措。尽量减少建筑物对环境的影响。

Each of the environmentally conscious and LEED compliant elements that went into the design and construction of the 20th Street Offices, has been put into a case study and signage program throughout the building for visitors, clients and the occupants themselves to use as an educational tool and test subject to experiment with future green building products and initiatives. And minimizing the buildings impact on its environment.
