WGBC: A guide to healthier homes and a healthier planet
The World Green Building Council launched a new guide to creating healthier homes that in turn, are healthier for the planet. The guide takes a combination of the latest research into air quality, thermal and acoustic comfort and lighting and translates it into simple, low-cost and practical strategies to make the home environment healthier for both people and planet. The world’s buildings have a direct impact both on the environment and on personal health and wellbeing, as well as having huge financial implications to owners and occupiers.
On average we spend 90% of our time indoors1, so the quality of the air we breathe can make a big impact on our health. More than half of the body’s air intake during a lifetime is inhaled in the home2. However, for 92% of us, the air around our homes is not safe to breathe3 and is linked to a range of health hazards.
Poor insulation and construction of buildings is often the cause of low energy efficiency and can compromise the occupant’s comfort and health. Around 65% of Europeans living in major urban areas are exposed to dangerously high levels of noise pollution4. This can lead to health issues such as stress, high blood pressure, hypertension and strokes4.
One study about living in a dark home found health worsened by 50% with headaches, insomnia and depression amongst other reported negative health impacts5. Therefore, good quality light, daylight when possible, is essential for a healthy life. Natural lighting is also an important energy reduction strategy in the home.
Patty Fong, Director for Buildings and Urban Systems, European Climate Foundation said: “This guide makes an important contribution to raising awareness around how the quality of our homes can negatively affect our health and productivity. By making the recommended improvements, we can make our living space healthier while also contributing to climate change mitigation.”

In a fast-changing political and economic environment, 2025 was a year of continued efforts to strengthen security, stability, and competitiveness for European businesses.
Throughout the year, our work demonstrated that energy efficiency is not only essential to achieving climate goals, but also a key driver of innovation, energy independence and sustainable long-term growth across Europe.
Strong engagement with policymakers, combined with the successful organisation of the 4th European Energy Efficiency Day, highlighted the importance of collaboration and dialogue in advancing shared objectives. Partnerships across sectors and institutions remained central to delivering impact and shaping effective energy policies.
Looking ahead to 2026, we will intensify our efforts to secure the regulatory certainty that can accelerate the energy transition, while providing businesses with the investment confidence they need and strengthening Europe’s competitiveness.
