‘Energy-Efficient Materials’ – Materials Save the Energy, Buildings Save the World

When discussing energy usage in buildings, we often think about lighting systems, large HVAC systems (chillers), water management systems, or smart building systems. These systems typically have environmental impacts, especially carbon dioxide emissions from buildings, which account for nearly 40% of global emissions. This major contributor to the greenhouse effect results in increasingly erratic weather patterns. Therefore, building owners and designers play a crucial role in supporting the concept of ‘energy-efficient buildings’ to maximize energy efficiency. Beyond environmental conservation, energy-efficient buildings provide long-term investment returns, enhance marketability, and most importantly, improve occupant comfort and health, elevating the quality of living.

To achieve consistent indoor temperatures, better air quality, and efficient lighting, effective thermal insulation and air conditioning systems that reduce indoor pollution are essential. This requires efficient resource use beyond just installing energy-saving equipment. Proper planning from the design stage, material selection, construction methods, and long-term maintenance are all critical.

  • Building Orientation and Renewable Energy: Selecting the building’s orientation and utilizing renewable energy can harness natural light and air circulation while minimizing exposure to extreme weather. For instance, converting sunlight into electricity and avoiding south-facing openings to reduce the cooling load on the building.
  • Designing Openings for Natural Light: Incorporating windows, skylights, and well-placed light tubes can reduce reliance on artificial lighting during the day. Energy-efficient lighting systems, such as LED bulbs, use less energy and last longer compared to traditional incandescent bulbs.
  • Smart Building Technology: Implementing smart building technologies to monitor and optimize energy use. These systems can be integrated into the design to automate operations for maximum efficiency.
  • Choosing Sustainable, Energy-Efficient Materials: Selecting environmentally friendly materials that meet building needs while offering durability and thermal insulation. These materials typically have the following characteristics:
    • Recyclable or Renewable Materials: Reduce environmental impact during production.
    • Non-toxic and Low-Emission Materials: Improve indoor air quality.
    • High Insulation Value (R-Value): Effectively reduce heat transfer.
    • Long Lifespan: Minimize the need for frequent replacements.
    • Moisture Resistance: Prevent mold growth.
    • Modular or Dry Installation Systems: Shorten construction time.
    • Easy to Clean: Reduce the accumulation of dirt and germs.

Applying Energy-Efficient Materials in Buildings:

For instance, Terratex terracotta tiles from FAMELINE are made from 100% natural clay, known for their strength and environmental friendliness. These tiles have a smooth, dense texture and meet ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 standards for energy-efficient production. The natural properties of clay provide excellent thermal insulation. The clip-lock installation system creates an air gap between the tiles and the wall, promoting natural ventilation and reducing heat entering the building. Available in four surface finishes, these tiles blend natural aesthetics with modern design.

Using Solar Panel Technology in PV Glass:

Additionally, FAMELINE offers materials that utilize natural sunlight by incorporating solar panel technology in PV Glass. This converts sunlight into electricity and is available in two types:

  • Cadmium Telluride PV Glass (CdTe): Features a thin film of cadmium telluride solar cells on two layers of laminated glass, with transparency levels from 0% to 40%, generating up to 145 watts per square meter. Suitable for building facades, it allows natural light while generating electricity.
  • Mono Crystalline PV Glass: Uses mono-crystalline solar cells between two layers of tempered glass, producing up to 148 watts per square meter with 20%-40% transparency. Ideal for skylights or carport roofs, it filters sunlight and generates electricity for building use.

Both types of PV Glass can be customized in size, color, thickness, and transparency to meet specific design requirements.


Materials that enhance building energy efficiency must also support diverse design concepts, maintaining the goal of creating outstanding, memorable aesthetics and promoting sustainable buildings. These materials save energy and preserve the planet, making the world a better place to live.
