The majority of the building stock is made up of existing premises, many of which are currently energy-inefficient. In 30 years’ time, a large proportion of these buildings will still be standing, which means that … - [Renovation](https://blog.swegon.com/en/tag/renovation) ### [Andreas Örje Wellstam](https://blog.swegon.com/en/author/andreas-örje-wellstam) ## [Taking on the climate challenge – a New York City perspective](https://blog.swegon.com/en/taking-on-the-climate-challenge-a-new-york-city-perspective) The climate discussion often tends to be very much focused on topics such as transportation and food production.
