项目简介
Introduction

坐落于阳光充沛、雨量丰富的热带地区，Ga.o之家是一个融合住宅与办公功能的混合型建筑。设计团队的目标不仅是满足日常使用需求，更在于探索更具前瞻性的策略：优先使用天然与再生材料、优化能源效率、利用可再生资源（太阳能、风能、水资源），并尽可能降低建筑全生命周期的碳排放。该项目体现了对越南可持续城市发展趋势的积极回应。

Located in a tropical region with abundant sunlight and rainfall, Ga.o House is a hybrid project that merges residential and office functions within a single structure. Beyond fulfilling basic usage needs, the design team set more ambitious goals: prioritizing the use of natural and recycled materials, optimizing energy efficiency, harnessing renewable resources (solar, wind, water), and minimizing carbon emissions throughout the building’s lifecycle. The project embodies an effort to align with Vietnam’s growing commitment to sustainable urban development.

设计策略
Design Solutions

为实现这些目标，建筑采用了预制钢结构，这是一种灵活、低废的建造方式，便于施工，也利于未来回收利用。建筑布局保持高度可变性，以适应功能变化。建筑面积被有效压缩，以释放更多开放空间，实现自然通风与采光，显著降低能源消耗。

To realize these objectives, the project employs a prefabricated steel frame — a flexible, low-waste solution that simplifies both construction and future recycling. The functional layout is deliberately adaptable, allowing spaces to evolve with changing needs. Built area is minimized to maximize open spaces, facilitating natural ventilation and daylight penetration, significantly reducing the building’s energy demand.

屋顶配备太阳能系统，每年可产生约11,000千瓦时电力，结合智能管理技术提升使用效率。雨水和灌溉用水通过收集系统回收再利用，减少水资源浪费。

A rooftop solar system generates approximately 11,000 kWh of electricity annually, managed by smart technology for efficient consumption. Rainwater and irrigation water are collected and reused, minimizing resource wastage.

空间组织
Spatial Organization

建筑共两层加一阁楼。首层设有办公区及小型吧台，满足员工的饮食需求。前庭融合绿植、水体与高差设计，营造多层次的景观体验，引导使用者亲近自然。庭院中种植的大树精心布局，既引入阳光，又保有自然的私密感。地基施工中挖出的天然石材被重新利用为台阶和室内构件，丰富了空间的触感与材料层次。

Ga.o House comprises two floors and an attic. The ground floor features an office area and a small bar catering to employee dining and beverage needs. A front garden blends greenery, water, and multi-leveled flooring to create layered vistas, inviting users to engage with the landscape. Mature trees are strategically planted to welcome sunlight while preserving a sense of intimacy with nature. Large stones, salvaged from the foundation work, are thoughtfully repurposed into steps and interior accents, enriching the space’s tactile and material experience.

二层设有可转换的私人办公空间，隐藏式折叠床巧妙收纳在书桌背后，实现办公与居住的灵活转换。中部挑空结构有助于空气对流及日光渗透。宽敞的前阳台设置瀑布与大型玻璃鱼缸，鱼池与屋顶水景之间形成循环水流，不仅调节微气候，也营造出静谧的声景。

The first floor includes a private office that can seamlessly convert into a bedroom via a concealed foldable bed behind the work desk. A substantial double-height void facilitates natural air circulation and invites daylight deep into the interior. The spacious front balcony incorporates a cascading waterfall and a large glass fish tank, where water circulation between the garden pond and the rooftop feature helps regulate the microclimate and introduces a gentle, soothing soundscape throughout the building.

阁楼为小型卧室，可眺望周边180度景致。建筑设有一面贯穿一至三层的立体绿墙，提升绿化覆盖率并改善室内空气质量。屋顶部分可开启，依据天气条件灵活调节通风与采光。其余屋面用于布置太阳能板、空调系统与水箱，全面支持可持续性能。

The attic level houses a small bedroom offering a sweeping 180-degree view of the surroundings. A continuous green wall stretches from the ground floor to the rooftop, expanding vertical greenery and enhancing indoor air quality. Part of the roof is operable, allowing for flexible natural ventilation and light access depending on weather conditions. The larger roof area accommodates solar panels, air conditioning systems, and water tanks, further supporting the project’s sustainable ambitions.

项目成果
Outcomes

通过系统性的整合策略，Ga.o之家成功减少60–80%的化石能源使用，每年可避免超过8.5吨二氧化碳排放。预计整个运营周期内将抵消超过200吨碳排放，相当于种植约3500棵树。

Through these integrated strategies, Ga.o House achieves a 60–80% reduction in fossil energy use and prevents the emission of over 8.5 tons of CO₂ annually. Over its operational lifespan, the project is expected to offset more than 200 tons of carbon — the equivalent of planting approximately 3,500 trees.
