Making the Earth a more beautiful and sustainable common home for everyone also means rethinking the spaces we live in. How can we improve the way we design our homes, build them, live in them and share them so that they become more resource-efficient, comfortable and healthy? Which solutions contribute to making them more sustainable? We meet with some of the Key stakeholders involved in making this transition.

We believe that if we are to improve life in the world, we must build cities that are more breathable, and therefore healthier, and which provide a better quality of life for everyone. Achieving that requires us to take concerted action to combat pollution - including inside our homes - reduce our carbon emissions, and conserve and expand pockets of the natural world. We wanted to discuss these issues with some of those who are working to deliver such a transformation.

Between 1950 and 2011, the world's urban population increased fivefold. In 2007, for the first time, the number of people living in cities surpassed the number of people living in the country. In 2019, the urban population had already reached 55% of the total population, and by 2050, it is estimated that just over two thirds of the population will live in urban areas.

How can personal desires for freedom of travel and mobility be reconciled more successfully with our shared expectations for sustainable development? What alternatives are there today? We reached out to meet with those who are inventing tomorrow’s solutions today.

With most of the world living in cities and growing villages, people tend to spend the majority of their time indoors. When not at home, we are working, learning, or even engaging in fun activities in enclosed, built settings. All in all, 90% of our time is occupied inside. It is therefore essential to ensure a comfortable, productive, and healthy indoor environmental quality by following well-regulated parameters and design practices that consider temperature, lighting, noise pollution, proper ventilation, and the quality of the air we breathe. The latter is especially important, since contra

In a predominately urban world that constantly has to deal with complex problems such as waste generation, water scarcity, natural disasters, air pollution, and even the spread of disease, it is impossible to ignore the impact of human activity on the environment.

Few things irritate us more than exposure to excessive noise or inability to hear what we need to hear. Whether it's a nearby construction site, highway traffic, air conditioning, or a neighbor learning saxophone, research shows that noise can contribute to cardiovascular disease, high blood pressure, headaches, hormonal changes, sleep disturbance, reduced physical and mental performance, and the reduction of well-being. On the other hand, in an acoustically "comfortable" environment, in addition to listening to what we want, we focus better and feel calmer.

Facades are the interface between the interior and exterior of a building. They are the most striking and visible parts of a building, they protect it from external agents and are one of the main contributors to creating comfortable environments since it is where thermal gains and losses occur. Just like our skin, an extremely versatile organ of our body, it should be natural for it to be the part of the building which bears technology capable of becoming adaptable to the environmental conditions of the place where it is located.

Thermal comfort becomes very evident when it is not attended to. When thermal conditions are adequate in one location, our body is in balance with the environment allowing us to perform activities normally. On the other hand, when a space is too hot or too cold, we soon see changes in our mood and body. Dissatisfaction with the thermal environment occurs when the heat balance is unstable, that is when there are differences between the heat produced by the body and the heat that the body loses to the environment
