The EDGE certification from IFC is an international green-building assessment system developed by the International Finance Corporation (IFC), a member of the World Bank Group. It requires buildings to achieve minimum savings of 20% in energy, water and materials compared with conventional local standards. On 16/7/2026, at the 2026 Vietnam Sustainable Construction Forum (VSCF Award 2026) held in Hanoi, IFC officially awarded EDGE certification to the Casa Luna project (Lot CN8-2) by Phú Mỹ Hưng. Importantly, this is not a merely symbolic certification but technical evidence independently verified by a reputable third party operating in more than 100 countries worldwide.
The EDGE-certified green building provides Casa Luna residents with 2 groups of practical benefits: economic benefits, including minimum savings of 20% on monthly electricity and water costs through solar-control glass, insulated double walls, high-efficiency water fixtures and an all-LED system; and health benefits, including VOC-free green materials, green space accounting for more than 50% of the total area and internationally standard indoor air quality. Moreover, these benefits are not merely one-sided commitments from the developer but technical criteria independently assessed and confirmed by IFC before certification was granted.
Compared with other international green certifications, EDGE is better suited to emerging markets and has lower implementation costs, while LEED is more comprehensive but considerably more complex and expensive, and BREEAM has the broadest assessment scope but is less common in Southeast Asia. Explore each aspect in detail in the article below to understand why Casa Luna’s EDGE certification is the most reliable quality signal for buyers and investors.
What is IFC’s EDGE certification, and how did Casa Luna Phú Mỹ Hưng achieve it?
EDGE certification (Excellence in Design for Greater Efficiencies) is an international green-building certification system developed by IFC, a member of the World Bank Group, for emerging markets. It requires buildings to demonstrate minimum savings of 20% in energy, water and the embodied energy of building materials compared with the local baseline.
To begin with, it is important to understand that the full name, “Excellence in Design for Greater Efficiencies”, accurately reflects its core philosophy: excellence in design to achieve greater resource efficiency. EDGE does not assess appearance or concepts; it assesses actual quantitative data. On 16/7/2026, at the VSCF Award 2026 organised by the Ho Chi Minh City Association of Construction and Building Materials (SACA) under the patronage of the Ministry of Construction, the Ministry of Agriculture and Environment and VCCI, IFC officially awarded EDGE certification to Casa Luna (Lot CN8-2) and Triton Crown (Lot CR9), two high-end apartment projects that Phú Mỹ Hưng commenced in the first half of 2026. This event marked an important milestone in Phú Mỹ Hưng’s consistent, long-term green strategy, as the certification was awarded at the design stage rather than after construction was completed. To understand the significance of this event more clearly, it is necessary to learn about the organisation behind EDGE certification and Phú Mỹ Hưng’s green journey.
What is IFC, and why does EDGE certification issued by IFC have global value?
IFC (International Finance Corporation) is the world’s largest development finance institution focused on the private sector. It belongs to the World Bank Group and operates in more than 100 countries, with the aim of promoting sustainable economic development in developing economies.
Specifically, IFC is entirely different from conventional industry associations or commercial organisations. It is an independent, non-profit international financial institution, established in 1956 and a core member of the World Bank Group. When IFC awards EDGE certification to a building, it is an endorsement from an organisation with no commercial interest in praising or denying the project’s quality. This gives it a completely different level of credibility from domestic certifications or those issued by industry associations.
EDGE certification issued by IFC carries 2 important meanings. First, it is independent technical confirmation that the building genuinely achieves internationally standard resource efficiency, measured using an objective quantitative methodology. Second, EDGE is a green finance signal that helps developers and residents access preferential international funding from the global green banking system, an increasingly important factor as ESG becomes a mandatory criterion in many capital markets.
Furthermore, the EDGE system was developed specifically to suit emerging markets such as Vietnam. EDGE software adjusts the resource-consumption baseline according to each country and climate zone, so the 20% savings criterion at Casa Luna is measured against typical building consumption in Ho Chi Minh City’s tropical climate, rather than against European or American standards such as LEED or BREEAM. This ensures that the certified savings reflect the actual operational efficiency that Vietnamese residents will experience. According to IFC, EDGE-certified buildings worldwide have reduced carbon emissions by the equivalent of millions of tonnes of CO2 each year, while also helping residents save considerably on operating costs throughout the buildings’ lifecycles.
Is Casa Luna Phú Mỹ Hưng’s first apartment project to achieve EDGE certification?
No, Casa Luna is not Phú Mỹ Hưng’s first project to achieve EDGE certification. However, Casa Luna is the highest-end project in Phú Mỹ Hưng’s EDGE-certified portfolio, affirming the group’s consistent and deeply rooted green strategy over many years.
More specifically, Cardinal Court was the first Phú Mỹ Hưng project to receive EDGE certification from IFC, while also becoming the first high-end residential project in southern Ho Chi Minh City to achieve this international green standard. Since Cardinal Court, Phú Mỹ Hưng has systematised EDGE standards throughout its design, material selection and construction processes, rather than treating them as an exception or merely a marketing highlight for individual projects.
In particular, at the VSCF Award 2026, IFC awarded EDGE certification simultaneously to Triton Crown (Lot CR9) and Casa Luna (Lot CN8-2), two projects that Phú Mỹ Hưng commenced in the first half of 2026. This was the first time Phú Mỹ Hưng had 2 projects certified with EDGE at the same event, demonstrating that EDGE is no longer the certification of a single project but has become a mandatory standard in the group’s long-term sustainable development strategy.
In summary, by choosing Casa Luna, buyers are not merely placing their trust in a single project but in a deeply rooted and consistent green development ecosystem, verified through a succession of projects. The EDGE certification awarded when Casa Luna commenced construction is the clearest evidence that green standards were integrated from the design stage, rather than added after construction was completed, confirming Phú Mỹ Hưng’s substantive commitment to sustainable development.
What practical benefits does an EDGE-certified green building provide to Casa Luna residents?
There are 2 main groups of practical benefits that an EDGE-certified green building provides to Casa Luna residents: economic benefits, including energy savings and reduced monthly operating costs; and health benefits, including high-quality green materials, clean air and an improved overall living environment.
It is important to emphasise that EDGE is not a certification based on conceptual designs or theoretical technical documentation. IFC requires the developer to demonstrate through actual quantitative data that the building achieves minimum savings of 20% compared with the local baseline before certification is issued. This assessment process includes checking each technical solution, every type of material and every piece of equipment used in the building. This is why Casa Luna residents can have complete confidence that the benefits below are not marketing promises but technical commitments independently verified by an international organisation.
What energy-saving and operating-cost benefits will Casa Luna residents receive from the EDGE standard?
There are 4 specific energy-saving and operational benefits provided by the EDGE standard to Casa Luna residents: electricity savings through solar-control heat-reducing glazing, lower water costs through EDGE-standard water-saving fixtures, reduced indoor temperatures through insulated double-wall construction and lighting electricity savings through an all-LED system.
Specifically, the table below summarises the 4 main technical solutions verified by IFC at Casa Luna, together with their estimated impact on residents:
| EDGE technical solution | Certified technical specifications | Direct benefits for residents |
| Solar-control heat-reducing glazing | Filters up to 99% of UV rays and blocks up to 79% of solar heat | Reduces air-conditioning loads by 30–40%, cutting monthly electricity bills |
| Double insulated walls (reinforced concrete + non-fired bricks or AAC) | Two wall layers significantly improve overall thermal insulation | Stable indoor temperatures, reducing reliance on air conditioning |
| EDGE-standard water-saving fixtures | At least 20% savings in water consumption | Reduced monthly water and water-heating costs |
| A fully integrated LED system throughout each apartment | Consumes 70–80% less energy than fluorescent lights of equivalent brightness | Saves on lighting electricity and reduces bulb replacement and maintenance costs |
The solar-control glazing system plays a central role in saving energy at Casa Luna. In Ho Chi Minh City’s tropical climate, air conditioning typically accounts for 40 to 60% of a household’s total electricity consumption. By preventing nearly 80% of solar heat from entering the living space, solar-control glazing significantly reduces the heat load that the air-conditioning system must handle, resulting in noticeably lower electricity consumption throughout the hot season. What is more, the glazing also filters up to 99% of UV rays, protecting residents’ skin and eye health in their daily living spaces while preventing interiors from fading and deteriorating prematurely due to ultraviolet radiation.
Casa Luna’s insulated double-wall construction uses a wall system comprising an external reinforced-concrete layer combined with internal non-fired brick or AAC (Autoclaved Aerated Concrete) walls. This cavity structure considerably improves thermal insulation compared with conventional single walls, maintains a stable indoor temperature and further reduces the load on the air-conditioning system even in hot outdoor conditions. The combined cumulative effect of the solar-control glazing and insulated double walls creates a much naturally cooler indoor environment than that of a typical luxury apartment.
According to an IFC report on the economic impact of green buildings in emerging markets, residents living in EDGE-certified buildings can save 15 to 30% of their total electricity and water costs compared with those living in equivalent buildings without green certification—substantial cumulative savings over the long term.
What green material and living-space standards at Casa Luna protect residents’ health?
Casa Luna incorporates 4 green-material and living-space standards that protect residents’ health: environmentally friendly building materials with controlled VOC levels, optimised indoor air quality, green space covering more than 50% of the total area and a comprehensive wellness ecosystem adjacent to the development.
More specifically, building materials selected according to EDGE criteria must meet stringent requirements regarding embodied carbon released during the manufacturing process and must not contain volatile organic compounds (VOCs) that are harmful to the respiratory system. This has particular practical significance for families with young children or older people, who are most sensitive to indoor air quality—a concern often overlooked in luxury apartment developments without independent green certification.
In addition, Casa Luna allocates more than 50% of the development’s total area to greenery, including multi-layered gardens, outdoor meditation areas and green corridors connecting the on-site amenities. This greenery not only creates an attractive landscape but also helps regulate the microclimate, reduce the urban heat-island effect and improve air quality around the buildings. More importantly, scientific research has confirmed that natural green spaces have a positive impact on psychological health, helping to reduce stress, improve concentration and enhance residents’ sleep quality.
Furthermore, the wellness ecosystem surrounding Casa Luna comprehensively complements the benefits of the green building. JCI-accredited FV Hospital, the global gold standard, is just a few hundred metres from the development, while Crescent Lake and Moonlight Park right next door provide unlimited natural space for walking and outdoor exercise. Casa Luna’s on-site facilities include an Infinity Edge infinity pool overlooking Crescent Lake, a private yoga studio, an individual spa in each apartment and a modern 3D golf room, creating a comprehensive living environment where residents do not need to leave the area to access the highest-quality physical and mental wellness services.
How does EDGE certification differ from LEED, BREEAM and other widely recognised international green-building certifications?
EDGE offers greater suitability for emerging markets and lower implementation costs, LEED is stronger in terms of comprehensiveness and global brand recognition, while BREEAM provides the broadest assessment scope but is the most complex and costly. Given Vietnam’s tropical climate and real estate market, EDGE is the optimal technical choice, which is why IFC specifically designed the system for emerging economies such as Vietnam.
However, each certification system has its own application context. To understand more clearly the differences and true value of the EDGE certification achieved by Casa Luna, the detailed comparative analysis below helps buyers and investors understand the development’s long-term competitive advantages.
How do EDGE and LEED differ, and why is EDGE more suitable for Vietnam’s real estate market?
EDGE and LEED differ mainly in 3 respects: the scope of assessment, implementation costs and suitability for the local climate. EDGE focuses on quantifying resource savings—energy, water and materials—through a streamlined process suited to emerging markets. LEED is more comprehensive but considerably more complex and costly, making it more suitable for commercial and office buildings in developed economies.
Vietnam lies in a hot, humid tropical climate zone, where reducing cooling energy and water consumption is the most essential priority. EDGE adjusts its baseline for each country, so Casa Luna’s 20% savings criterion is measured against typical consumption levels for buildings in Ho Chi Minh City’s climate, ensuring that the certification accurately reflects the operational efficiency residents will experience in practice.
How does Casa Luna’s EDGE certification affect property value and long-term investment potential?
Casa Luna’s EDGE certification positively affects the property’s value in 3 ways: creating a Green Premium over apartments without green certification, enabling access to international green finance and attracting international tenants who understand ESG and have strong purchasing power.
The Green Premium in Ho Chi Minh City’s luxury property market is becoming increasingly evident as international financial institutions, foreign companies and expatriate residents increasingly prioritise independently certified green apartments. In addition, as ESG becomes a mandatory investment criterion in many international capital markets, properties bearing IFC’s EDGE certification have an advantage in accessing green funding from international banks and investment funds—an element that helps preserve and increase long-term value, and that most luxury apartments without green certification cannot match.
