In addition, considering that the enclosure structure in the heating room needs to bear the load in the algorithm of intermittent heating energy consumption by room, and its thermal performance has an impact on the heating energy consumption, therefore, on the basis of the first three types of enclosure structure practices, the enclosure structure in the heating room is increased with heat preservation measures, and 20 mm heat preservation mortar is smeared on both sides of the partition wall of the conventional 240 mm clay bricks in the heating room, and 30 mm inorganic fibers are sprayed under the ordinary concrete floor slab to realize the energy transmission between the partition wall and the floor slab. The heat transfer coefficient K of the partition wall and floor slab is reduced to 1.00 W/(m2-K). A total of six envelope practices, respectively, the status quo, GB/T 50824, GB/T 50824 revision, status quo + internal envelope insulation, GB/T 50824 + internal envelope insulation and GB/T 50824 revision + internal envelope insulation.

Compared to London 2012 and Rio 2016, Paris 2024 is striving to reduce its carbon footprint by 50 percent in a bid to become the first Olympic Games to meet the Paris Agreement's goal of halving global emissions by 2030.

On August 1, 2024, "Built Environment Health, Low Carbon and Resilience Frontier Science and Technology Forum and HVAC Magazine 2024 Annual Meeting" was successfully held in Xi'an, hosted by Asia-Pacific Institute of Construction Science and Technology Information Research (APCSTI) HVAC Magazine and co-sponsored by Northwest China Architecture Design and Research Institute (NWCDRI).

As global warming becomes more and more obvious, energy saving and emission reduction become more and more important. And in energy saving and emission reduction, windows actually play a key role: strong solar radiation generated by the hot sun in summer will increase the indoor temperature through the window glass, and indoor heat in winter can be released to the outside world through the window glass. The energy lost through windows can amount to half of a building's energy consumption. So many scientists are focusing on windows.
