It's been four years since the VELUX Group, together with partners EFFEKT architects and Artelia engineers, first embarked on Living Places. The experimental housing project demonstrated that building more sustainable homes using readily available products, materials and technologies is possible. Putting the ultra-low carbon housing concept to the test, VELUX conducted a study with 98 live-in guests to evaluate whether sustainable homes can also provide indoor comfort. Using a combination of environmental sensors and guest questionnaires, the findings reveal that the homes maintain a comfortable indoor climate in line with European Standards and had a positive effect on the well-being of guests, showing that building for planet can also greatly benefit people.
