-Due to global warming, the topic of protection against overheating is becoming increasingly important, especially since high indoor temperatures are not only a question of comfort, but can also be highly detrimental to health. Due to rising external temperatures, active cooling is increasingly becoming necessary in order to achieve adequate summer comfort also in climates and locations where this it was historically not needed (e.g. in Central Europe). In energy-efficient buildings, this can be realised in a climate-friendly way with very low energy consumption and should be taken into account by planners and building owners as part of the planning process in a future-oriented way. More on this in the articles linked below.+Important: Due to global warming, the topic of protection against overheating is becoming increasingly important, especially since high indoor temperatures are not only a question of comfort, but can also be highly detrimental to health.

-The perception and measurement of [[basics:building_physics_-_basics:thermal_comfort|thermal comfort ]] in summer is quite complex. Ultimately however, the operative temperature is the decisive benchmark also for assessing thermal comfort in summer; in addition, humidity and air velocity play an important role. In buildings without active cooling, it is usually accepted that temperatures may be slightly above the comfortable range at times. The **frequency of overheating** i.e. the proportion of hours of the year that are above a certain limit, was introduced as a measure of summer comfort in passively cooled buildings. In a Passive House building and in the PHPP, the frequency of overheating events always refers to a temperature limit of 25°C. A value of 10% is considered as still acceptable, but building design should aim for less than 5%. The frequency of overheating is calculated for the entire building during the desin process using the [[:planning:calculating_energy_efficiency:phpp_-_the_passive_house_planning_package|Passive House Planning Package (PHPP)]].Further reading: [[:phi_publications:pb_15:a_simplified_method_for_determining_thermal_comfort_in_summer_for_buildings_without_active_cooling]] +The perception and measurement of [[basics:building_physics_-_basics:thermal_comfort|thermal comfort ]] in summer is quite complex.

-For buildings with **[[planning:summer_comfort#active_cooling |active cooling]]**, the summer comfort level of max. 25°C should be achieved with the lowest possible energy demand. This can also be easily calculated using the [[:planning:calculating_energy_efficiency:phpp_-_the_passive_house_planning_package|Passive House Planning Package (PHPP)]] during the planning process. The limit value for the useful energy demand for active cooling in a Passive House building is a maximum of 15 kWh/(m²a) in the climate of Central Europe.+For buildings with [[planning:summer_comfort#active_cooling |active cooling]], the summer comfort level of max. 25°C should be achieved with the lowest possible energy demand.

-**Optimising the building design** to suit local climate conditions and building use has a fundamental impact on the level of thermal comfort achieved in summer and the energy required for active cooling. It also determines how robust and resilient the building is against the risk of overheating during hot spells, and generally rising temperatures.

-A temperature increase in a building is ultimately caused by net heat gains. The very first principle for building optimisation and building use through passive cooling measures is therefore to reduce all potential heat sources, e.g. solar gains and internal heat sources. If the temperature rises above the comfortable level, the only effective way to passively dissipate the excess heat is through ventilation at times when the outside temperature is sufficiently low.

 The boundary conditions that are used for the calculations during the design phase may differ from those of the actual building one it is in use, e.g. the actual weather of that particular day or year and the user's interaction witht he building. A risk analysis by means of **stress testing** a design is essential for a robust summer comfort strategy. It provides valuable feedback and a better understanding of the risk factors for overheating and can thus lead to more robust and resilient designs. Stress testing is integrated into the planning tool PHPP version 10 onwards: it shows the calculated frequency of overheating for various scenarios during the planning process. The boundary conditions that are used for the calculations during the design phase may differ from those of the actual building one it is in use, e.g. the actual weather of that particular day or year and the user's interaction witht he building.

 The behaviour of residents or users can have a strong influence on the temperatures inside the building, especially with regard to the use of shading elements and ventilation (especially at night, when it is cooler outside than inside the building). Users are not always sufficiently aware of the interrelationships or external circumstances may prevent them from using the full potential of shaing or night ventilation. In order to prevent misunderstandings, it can be helpful to document the passive cooling strategy planned for a specific building and make this available to the users.  A template for a [[https://passipedia.org/planning/summer_comfort/summer_comfort_user_manual|user manual]] was created as part of the EU project [[https://outphit.eu/en/|outPHit]], which explains basic relationships of passive cooling and can be supplemented with specific recommendations for the building. The behaviour of residents or users can have a strong influence on the temperatures inside the building, especially with regard to the use of shading elements and ventilation (especially at night, when it is cooler outside than inside the building).

 Ongoing global warming is leading to a changing climate worldwide. This affects all buildings, regardless of their efficiency level. Buildings built today will likely be exposed and used in warmer conditions than what we are familiar with today. For future-oriented planning, it is imperative to take the impact of warming climate conditons on summer comfort into consideration. The risk of higher overheating frequencies will increase by the middle of the century and active cooling will probably become necessary in many places where this is not currently the case. Planners and building owners are well advised to take this into account in their design decisions, i.e. to assume warmer summer conditions and implement active cooling form the outset, or at least make plans for simple cooling retrofit measures. Ongoing global warming is leading to a changing climate worldwide.

 If a building (or individual rooms) cannot be kept cool realibly using only passive cooling measures, there is always the option of active cooling. The energy demand and cooling loads in a Passive House building or an existing building renovated to the EnerPHit standard are so low due to the high level of energy efficiency that active cooling can be implemented in a technically simple and climate-friendly way. For a detached house, a single split system air conditioning unit is usually sufficient (an extremely cost-effective solution that can also be used for heating). The months in which active cooling is required in Europe generally coincide well with the availability of renewable solar energy. This means that in almost all cases, the additional energy demand can be met easily and efficiently using sustainable resources, as demonstrated by the [[basics:energy_and_ecology:primary_energy_renewable_per|PER assessment method]]. Due to the further expansion of photovoltaics, which is necessary in any case, in just a few years' time there will even be surplus electricity in the power grid in Germany, especially during hot periods. If a building (or individual rooms) cannot be kept cool realibly using only passive cooling measures, there is always the option of active cooling.

 In warm and hot climates, active cooling for a good level of thermal comfort is out of the question ((People are often surprised that Passive House experts have no 'problem' with active cooling: however, this should not be surprising at all since the Passive House approach does not pursue the "absolute zero approach", even for heating; instead, it aims for an economically reasonable reduction in the demand to a level with which renewable coverage will no longer be a problem in economic and ecological terms: that is the annual heating demand of 15 kWh/(m²a); for Central Europe, an equally high upper limit for the annual cooling demand in residential buildings can be easily met using thermal protection and sun protection, and the associated electricity demand is then less than 4 kWh/(m²a), which is generated only in summer - this can usually even be met by the building's own photovoltaic system.))
