tial increase of these impacts as climate change progresses. Results of the pro-
ject should provide the know-how to the European community ranging from
the individual citizen to public and private policymakers towards implement-
ing methods and procedures that will secure health and productivity despite
aggravated workplace heat levels.

According to World Health Organisation (WHO, 2015), it is anticipated
that the rising temperatures in Europe during the 21st century will have signifi-
cant detrimental impacts on the health of local populations – especially in oc-
cupational settings – and, as climate change becomes more prevalent, excess
heat-related morbidity and mortality will rise between 3% and 6%. Air tem-
peratures in Slovenia have already increased more than in average in Europe,
for instance in Ljubljana in the period 1961–2011 by 0.4°C per decade, maxi-
mum values and summer averages even more (ARSO, 2014). Under the mod-
erate RCP4.5 scenario it can be expected that will the average air temperature
in Slovenia in 2011–2040 increase by 1°C regarding the period 1981–2010 and by
another one degree in the next 30-year period (ARSO, 2016). Also, the number
of hot days and heat waves is increasing; one example can be seen in Figure 1,
showing the decadal number of days and average maximum air temperature in
heat waves in Bilje in the period 1966–2015.

temperature (gray) in heat waves (at least 5 consecutive days Tmax ≥
29.5°C) in years from 1966 to 2015 in Bilje(data: ARSO, 2016).
The hottest part of Slovenia is southwest. For example, in Bilje near No-
va Gorica in 1960. and 1970. years in average 15 to 30 hot days (maximum dai-
ly air temperature equal or higher of 30°C) were detected per year, while in last
15 years there was 35 to 50 hot days per year. In 2003 daily maximum air tem-
perature was higher than 30°C every day between 15 July and 24 August. There
is also an increase in the number of tropic nights (minimum daily air tempera-
