SMALL IS BETTER
One room = 100 trees
The smaller is the house, the less is the impact on the environment. Not heating one room (20m2) reduces CO2 emissions by one tone (1.000kg) per year. Equivalent to planting 100 trees
On our planet the we’re continuing building new houses, and (almost) each of them needs to be heated during winter, and often cooled in summer.
It means that we’ve always more space to heat, and this is one of the major reasons for the increase of CO<sub>2</sub> emissions.
As populations and people gain welfare, they tend to buy bigger homes, even to the status that they confer a social level.
People who care for environment should carefully consider home size and type before purchase it.
Villas and independent house, having a high surface in contact with the exterior have a
greater dispersion of heat. For this reason, the houses of this type, especially if not properly insulated, have a significant environmental impact.
Big buildings with many flats, have less external walls to be heated, more ceilings and floors in contact with other apartments, and then the energy supplies are reduced.
On consequence a 10-storey building with 50 apartments, although aesthetically less pleasant, is actually much greener than 50 indipendent family houses.
And this has a good impact also in mobility, because, when a greater number of people is focused in less space, also public transport is more effective.
But when we think to our “heated space” we need to think not only to our home. We usually use also other buildings during the day and also these ones have an environmental impact, and a part of it is due to us.
If you work outside home, if you go to the gym, or you have a drink at the bar, a part ot the related CO2 emissions belongs to you. Reduce the number of frequented buildings or reduce the time spent there, reduces our environmental impact. So think to alternatives: Instead of going to the gym you can go for a run in the park, rather than have a drink at the bar you can go to a friend’s house….
And in your job you could ask your employer if you can work from home for a few days in a month: it would save also CO2 emissions due to mobility…
