Energy-Efficient Buildings in Turkey: Savings, Security & Better Lives

In the face of rising energy demand and dependence on imports, Turkey has taken bold steps to make public buildings warmer, greener and more cost-efficient. With support from the World Bank, a national initiative is retrofitting schools, hospitals and government offices, delivering major savings, enhancing comfort, and helping build a more resilient future. 

The Challenge: The Building Sector’s Hidden Cost

Buildings often leak energy through outdated systems, poor insulation and inefficient lighting. In Turkey, the building sector alone accounts for about one-third of the country’s total energy use, much of which is supplied with coal or natural gas. 

This means high bills, vulnerability to global supply shocks, and heavy carbon emissions.

What’s Being Done: Retrofitting Public Buildings

The “Turkey Energy Efficiency in Public Buildings” project – funded by the World Bank – is renovating hundreds of central-government buildings (offices, schools, hospitals).

‍
Key measures include:

• Upgrading insulation (walls, roofs) & high-performance windows (e.g., triple-paned)
  
• Replacing outdated heating/cooling systems, installing LED lighting
  
• Incorporating solar panels to generate clean energy on-site
  

The results so far? In over 370 retrofitted buildings, average energy use has dropped by about 40%, more than twice the original target. 

Real-World Impact: Schools & Hospitals

Schools: At the Ortaköy 80th Year Vocational and Technical Anatolian High School near Ankara, upgrades included triple-paned windows, better insulation, LED lighting and solar panels. This campus of ~500 students now sees electricity consumption cut by roughly 60-70%. One deputy headmaster reported that previously classrooms were cold and students absent; now they’re warmer and more engaged. 

Hospitals: At the Kandıra State Hospital (52-bed facility serving ~60,000 people) in Kocaeli province: over 1,000 fluorescent lights replaced with LED, more than 400 solar panels installed. Energy consumption fell 30%, eliminating roughly 420 tonnes of carbon emissions. Savings freed up funds for medicines and cleaning services. 

Scaling Up: Toward a Greener, Resilient Future

The Turkish government now plans to take this beyond pilot scale, aiming to retrofit half a million public buildings, with an estimated investment of $8.8 billion. The program also offers jobs: the first phase trained over 3,500 people in energy services and construction.

As part of Turkey's net-zero target for 2053, the goal for public building energy reduction has been revised from 15% to 30%. With early results showing approximately 40% savings are possible, the ambition is real.

Why This Matters

• Economic resilience: Reducing import dependence for heating/energy improves national energy security.
  
• Social benefits: Better-insulated, well-lit schools and hospitals mean healthier, more comfortable spaces and improved outcomes for students and patients.
  
• Environmental impact: Lower energy consumption = fewer greenhouse gas emissions = progress toward climate goals.
  
• Job creation & skills: Scaling this effort creates employment in retrofit, construction and energy-services sectors.

Key Takeaways & Lessons for Other Countries

• Public building retrofits can be both socially and economically beneficial (not just “green” but smart investment).
  
• Combining insulation, modern HVAC systems, efficient lighting and renewables (solar) yields the strongest results.
  
• Training and workforce development are critical when scaling up.
  
• Target setting matters: moving from 15% → 30% savings shows ambition can shift when early results are strong.

Call to Action

For governments, building owners, schools, hospitals and contractors: consider how energy-efficiency retrofits can reduce operating costs, improve occupant comfort and bolster resilience. Look to Turkey’s example: strong results, replicable tools, and a win-win for economy and environment.

The story of Turkey's energy-efficient buildings is not just about kilowatts saved, but it’s alsoabout classrooms where students focus, hospitals where patients heal, jobs for workers upgrading systems, and a nation building a secure, greener future.
