Balancing Sustainability, Efficiency, and Performance
Data centers are the backbone of the digital economy, but they are also one of the most energy-intensive building types. In Malaysia’s hot and humid climate, the challenge is even greater—cooling systems must work overtime to prevent server overheating, and energy consumption is skyrocketing as data demand increases.
To create an ecologically responsible data center, architects and engineers must rethink traditional approaches, focusing on energy efficiency, climate-responsive design, and renewable energy integration. In this article, we explore the key considerations for designing a sustainable data center in Malaysia, with a special emphasis on facade strategies that reduce heat transfer and improve overall efficiency.
1. Key Factors in Designing a Sustainable Data Center
1.1 Energy Efficiency & Cooling Strategies
Cooling accounts for over 40% of total energy consumption in a data center. In Malaysia’s climate, efficient cooling systems are non-negotiable for sustainability.
- Liquid Cooling & Immersion Cooling: These advanced techniques use water or dielectric fluid instead of traditional air cooling, drastically reducing energy use.
- AI-Powered Smart Cooling: AI can optimize cooling in real time, adjusting temperature and airflow based on server load.
- Free Cooling & Heat Recovery: Leveraging cool nighttime air (where possible) and reusing waste heat for adjacent buildings can improve efficiency.
1.2 Renewable Energy Integration
Given Malaysia’s push towards sustainability (e.g., National Energy Transition Roadmap), incorporating solar panels, hydropower, and battery storage into data centers can reduce dependence on fossil fuels.
- Solar PV Panels: Integrated into rooftops and facades to generate on-site renewable energy.
- Green Power Purchase Agreements (PPA): Partnering with renewable energy providers to offset carbon footprint.
1.3 Sustainable Materials & Embodied Carbon Reduction
Data centers require massive amounts of concrete and steel, both of which have high embodied carbon. Sustainable alternatives include:
- Recycled steel & low-carbon concrete to reduce emissions.
- Prefabricated modular construction to cut waste and improve efficiency.
- Locally sourced materials to reduce transportation carbon footprint.
"Sustainability in data centers is not just about operational energy efficiency; it’s about reducing the carbon footprint across the entire lifecycle of the building," says Clarence Chia, Director of AND Lab.

2. Facade Design to Minimize Heat Transfer & Energy Consumption
2.1 The Role of Facade in Energy Efficiency
In tropical climates like Malaysia, heat gain through the facade increases cooling loads. A well-designed facade can significantly cut energy consumption by:
- Reducing direct solar heat gain
- Enhancing natural ventilation
- Minimizing reliance on mechanical cooling
2.2 Strategies for an Energy-Efficient Data Center Facade
1. High-Performance Double-Skin Facades
- Creates an insulating air gap that reduces heat penetration.
- Enhances natural airflow to cool exterior surfaces.
- Allows for passive shading while maintaining natural light intake.
2. Solar Shading & Dynamic Facades
- External shading elements (louvers, fins, perforated screens) block excessive sunlight.
- Electrochromic glass adjusts transparency based on sunlight intensity.
- Green walls & vertical gardens act as natural insulators and improve urban microclimates.
3. Reflective & High-Performance Materials
- Low-emissivity (Low-E) glass minimizes heat absorption.
- Reflective coatings on walls and roofs reduce thermal gain.
- Cool roofs (white or high-albedo materials) lower surface temperatures.
"A well-designed facade is the first line of defense against excessive cooling demand. By controlling heat transfer at the envelope level, we can drastically reduce the need for artificial cooling," Chia explains.
3. Water & Waste Management in Data Centers
Water usage is another overlooked aspect of data center sustainability. Traditional cooling towers consume vast amounts of water. Sustainable alternatives include:
- Closed-loop water cooling to minimize wastage.
- Rainwater harvesting for non-critical operations.
- Greywater recycling to reduce overall water footprint.
Additionally, electronic waste (e-waste) management must be addressed, with responsible recycling of outdated servers and IT components.
4. The Future of Green Data Centers in Malaysia
As Malaysia moves towards carbon neutrality, the data center industry must align with global sustainability trends:
- Hyperscale data centers with green certifications (LEED, GreenRE, or EDGE).
- AI-driven optimization for energy and cooling management.
- Integration with smart cities for shared infrastructure and sustainability synergies.
"The data centers of the future must be energy-efficient, climate-adaptive, and seamlessly integrated into their urban context," Chia emphasizes.
Rethinking Data Center Design for a Sustainable Future
Building an ecologically responsible data center in Malaysia requires a holistic approach—balancing energy efficiency, material sustainability, heat mitigation, and renewable energy integration. Thoughtful facade design, smart cooling strategies, and sustainable construction materials will define the next generation of green data centers.
At AND Lab, we believe that sustainable data center design is not just about reducing energy use—it’s about future-proofing digital infrastructure while minimizing environmental impact. The challenge is immense, but with innovative architectural solutions, Malaysia can lead the way in creating climate-responsive, energy-efficient data centers.

A notable data center in the Philippines has achieved a Power Usage Effectiveness (PUE) of 1.193, surpassing its design target and positioning itself among the most energy-efficient data centers in the region. This accomplishment demonstrates the potential for data centers in Southeast Asia, including Malaysia, to adopt innovative designs that significantly reduce energy consumption.
2. Advanced Facade Design Strategies
Incorporating advanced facade designs is crucial for minimizing heat transfer and reducing energy consumption in Malaysia's tropical climate.
2.1 Double-Skin Facades
A double-skin facade consists of two layers of exterior surfaces with an air cavity between them. This design acts as an insulating barrier, reducing heat gain and facilitating natural ventilation. The air cavity can be ventilated naturally or mechanically, aiding in dissipating heat before it reaches the interior spaces.
2.2 Green Facades and Vertical Gardens
Integrating vegetation into facade designs, such as green walls or vertical gardens, provides natural insulation and reduces surface temperatures through evapotranspiration. This approach not only enhances energy efficiency but also improves urban biodiversity and aesthetics.
