1st June 2001. The Thermal Regulations 2000 (RT 2000) come into force, following the Rio and Kyoto agreements. It applies to new buildings.<\/p>\n

It introduces a new concept: summer comfort.<\/strong><\/p>\n

For buildings, this means limiting the indoor temperature during the hot season. The conventional indoor temperature<\/strong> or Tic must therefore be lower than a reference temperature.<\/strong><\/p>\n

This initial approach plays a beneficial role in the design of the building envelope<\/strong>. In fact, it has been maintained in new building regulations (RT 2005 and RT 2012). Tic appeared in 2008 in the thermal regulations for existing buildings<\/strong>, inspired by RT 2005.<\/p>\n

However, several criticisms have been levelled at this indicator, the main one being that it is out of sync with the discomfort perceived<\/strong> by occupants. What’s more, ceiling fans<\/strong>, which have proved their worth in terms of perceived thermal comfort and deliver significant energy savings, cannot have an impact on Tic<\/strong>.<\/p>\n

It wasn’t until January 2022, when the 2020 environmental regulations<\/strong> (RE 2020) came into force for new buildings, that a new indicator<\/strong> was introduced: the degree-hour of discomfort<\/strong> or DH. With this new value, ceiling fans are included in the regulations.<\/strong><\/p>\n

However, today, summer comfort is still at the same stage for renovations to existing buildings. The 2018 update of the existing building regulations maintains the Tic limit.<\/strong><\/p>\n

Fortunately, things are changing: the new energy performance diagnosis<\/strong>, which comes into force on 1 July 2021, opens the door wide to summer comfort<\/strong>.<\/p>\n

New DPE (Energy performance diagnosis) : making solutions visible<\/h2>\n

Summer comfort is reflected in the new DPE (Energy performance diagnosis) by an overall view<\/strong> of the situation, with three possible levels of smileys: insufficient, average and good.<\/p>\n
