Green Offices – A Long-Term Solution for Cost Efficiency and Operational Performance

According to the United Nations Environment Programme (UNEP), buildings account for approximately 40% of global energy use and nearly a third of greenhouse gas emissions.  Converting high rise developments into energy efficient and environmentally friendly spaces is not only a strategic solution for climate change but also an action that delivers clear long-term economic benefits.

In this context, the LEED certification system, developed by the U.S. Green Building Council (USGBC), has become a global benchmark for assessing a building’s sustainability. In Europe, shifting just 20% of heating demand to clean energy could cut CO₂ emissions by 9% and save an estimated €3 billion in healthcare costs by 2030 through improved urban air quality (World Green Building Council, 2023). In Vietnam, while the number of LEED-certified buildings remains limited, demand for green office spaces from both domestic and international businesses is becoming evident, especially in a city with high commercial activity and population density like Hanoi. Certified green spaces not only drive operational savings but also enhance employee wellbeing, boost productivity, and strengthen corporate reputation.

Ms. Hoang Nguyet Minh, Senior Director, Director of Commercial Leasing, Leasing at Savills Hanoi, shared: “Green certification is no longer just a competitive advantage, it has become a new standard for Grade A offices. Green buildings allow companies to demonstrate their ESG commitments, while strengthening their corporate image and attracting high-quality talent."

Oriental Square by OSI - A Commitment to Sustainable Development from Concept to Operation

Located in the new administrative and economic center, Oriental Square by OSI is the first Grade A office in Starlake to pursue LEED Gold certification. The building is engineered to provide a healthy, cost-efficient workplace while minimising its environmental impact. Specifically, the project aims to create a healthy working environment that improves user wellbeing by 20%, reduces climate impact by 35%, and cuts water consumption by 15% compared to conventional office buildings.

Oriental Square by OSI is the first Grade A office and commercial building in the Starlake, honored at the 2024 PropertyGuru Vietnam Property Awards with two prestigious awards: “Best Office Development” and “Best Commercial Green Development”, while also being named a finalist for “Best Office Development” at the Asia Property Awards, underscoring its credibility and quality in the broader regional market.

From the planning stage, Oriental Square by OSI integrated advanced green engineering solutions. A column-free layout and 4,500 mm ceiling height enable maximum flexibility, enhance natural light penetration, and promote efficient airflow—resulting in an estimated 10% reduction in greenhouse gas emissions in compliance with LEED standards.

All construction materials at Oriental Square by OSI were selected for their sustainability: Saint-Gobain Low-E glass (France) blocks up to 80% of UV rays and solar heat, structural steel imported from Switzerland ensures durability; and the fire-resistant electrical system meets Singapore standards. The high-performance Daikin central air-conditioning system exceeds the market average by 30%, working in tandem with UK-made Breeze air filtration, CO₂ sensors, and UV lighting to maintain consistently high air quality—a critical factor in employee health and workplace productivity.

Energy efficiency is further enhanced through Schneider LED lighting systems, smart sockets, and a fully integrated BMS–PMS management platform, enabling real-time energy monitoring and consumption control. Altogether, these systems are expected to deliver annual energy and operations savings of 20–25%—a significant competitive edge amid rising operating costs in Hanoi.

The project is not only optimised for operational efficiency but is also engineered to adapt to long-term urban dynamics. Its robust structural system features dual layers of reinforced concrete imported from Switzerland and is designed to withstand earthquakes up to magnitude 7 on the Richter scale—ensuring long-term stability and safety.

Set for completion and handover by the end of 2025, Oriental Square by OSI will introduce nearly 14,000 sqm of prime office and retail space to the market. The development is particularly well-suited for companies in technology, finance, and professional services that are seeking a modern, tech-integrated workspace aligned with global sustainability benchmarks.

With its strategic location, advanced construction standards, and a clear green commitment, Oriental Square by OSI is asserting its pioneering role in shaping the next generation of office spaces in Hanoi—a workplace designed for long-term vision, efficient operations, and sustainable growth. It is the ideal choice for businesses seeking a stable, high-performing environment aligned with their sustainability strategies.
