The science of sustainable living

Embracing green-living guidelines could benefit the environment and both the well-being and finances of homeowners

The concept of sustainable living has gained significant traction in recent years as individuals and communities strive to reduce their environmental impact.

In Saudi Arabia, where rapid urbanization and economic growth have led to increased energy consumption, the importance of adopting green living practices cannot be overstated. “When designing or buying a new home, it is important to consider the insulation levels of walls and windows,” Thaer Qasem, senior energy engineer at SETS Saudi Arabia, told Arab News.

“The choice of building orientation can also increase natural light and help reduce heat absorption.” Integrating smart home technology for monitoring and controlling energy usage allows residents to optimize their consumption and identify areas where efficiency can be improved. Proper insulation, sealing, and the use of efficient heating, ventilation and air conditioning systems are also essential in preventing waste and maintaining a comfortable indoor environment.

Similarly, using recycled glass not only diverts waste from landfills but also reduces the energy required to produce new materials.

Khalid Al-Harbi, an architect based in Riyadh, said a common misconception around sustainability is that it relies solely on the energy systems, equipment, and material choices used in the building.

“A well thought out architectural design that studies the needs of the users and considers the environmental factors will significantly reduce the cost and energy use of the building,” Al-Harbi told Arab News. “Through studying the solar orientation of the sun in both summer and winter, we can decide on the most efficient placements of the windows and the shading systems needed such as exterior screens, outdoor shades, curtains, and so on, throughout the building.”

Clay walls have emerged as a popular choice for eco-conscious homeowners due to their natural insulation properties, humidity regulation, and sustainability. According to Adam Weismann, founding director of Clayworks and Claymoon, clay is a sustainable, non-toxic alternative.

“From a sustainability perspective, clay has a very minimal carbon footprint because it is a pure substance with no chemicals,” Weismann told Arab News. “Additionally, from a toxicity perspective, there is nothing that clay can truly release into the atmosphere. Thus, using it is a highly healthy and beneficial solution.” Traditional Saudi architecture has long used sun-dried clay blocks, which remain cool during hot weather and release heat during the late hours when the temperature drops.

In addition to using sustainable materials, implementing energy-efficient strategies is key to creating eco-friendly homes in Saudi Arabia.

One effective approach is the installation of solar panels or solar water heaters to harness the

abundant sunlight in the region. “However, a government incentive is needed to push people towards incorporating solar panels in their homes,” said Al-Harbi. “Many countries offer subsidies to their citizens where they help with 30-70 percent of the cost of solar systems.

“The incentive programs are usually done with tax credits, lowering bills, low interest loans, etc. We’re confident that these types of programs will soon be implemented in the country.”

Part of the battle will be changing consumer behavior. Qasem believes raising awareness is essential to making effective energy savings. “Various easy methods make a big difference,” he said. “Turning off lights and AC when not needed, closing the windows and doors to conserve energy, using the washing machine at full capacity only, and using sunlight to your advantage are just a few.”
