-It is important to talk about these regions, as they face not only climate change, but also a continued growth in population and a trend of rapid urbanisation. These often come together with a housing backlog, so there is an urgency for more housing possibilities. At the same time, the living standards must be improved and are rapidly changing in many of these countries. For all these reasons, and in combination with the effects of climate change, a continued increase in energy demand, especially for active cooling, is expected. +It is important to talk about these regions, as they face not only climate change, but also a continued growth in population and a trend of rapid urbanisation.

-As shown in the map below, the Global Energy Assessment [Ürge-Vorsatz et al. 2012] revealed that employing sub-optimal solutions (business as usual) would lead to a substantial energy increase in many of these regions by mid-century, accompanied by a high risk of lock-in. On a worldwide scale, employing state of the art technologies indicates a reduction potential in energy the energy demand for heating and cooling of 46% compared to 2005 figures; and would prevent 79% energy needs (lock-in risk) compared with a sub-optimal development. +As shown in the map below, the Global Energy Assessment [Ürge-Vorsatz et al. 2012] revealed that employing sub-optimal solutions (business as usual) would lead to a substantial energy increase in many of these regions by mid-century, accompanied by a high risk of lock-in.

-In other words, how high the increase in the energy demand will be for these regions will depend on the solutions that we implement today. So we need to start planning for high energy efficiency and avoid interim solutions. Luckily,  Passive House has proven to be a viable solution for this that goes way beyond energy savings of the individual building – it can play a direct role in achieving many of the current sustainable global aims (for [[basics:passive_house_and_the_sustainable_development_goals|example the SDG’s ]] as defined by the UN), among them health and comfort, equity and resilience [Tzar 2021].+In other words, how high the increase in the energy demand will be for these regions will depend on the solutions that we implement today.

 Studies are a great way to show that Passive House is not only technically but economically feasible for different typologies and in a variety of climates. They can pave the way by showing technical solutions and sparking interest in the regional market. Ultimately, pilot projects are the best way to show how the performance values of the Passive House criteria can be successfully incorporated to respond to local requirements and designs. Nothing is more convincing than walking into a Passive House and experiencing firsthand comfort and better air quality. Studies are a great way to show that Passive House is not only technically but economically feasible for different typologies and in a variety of climates.
