Expected Savings
AIR HEATING, ENERGY SAVINGS
Without measures, AH and reversible AC would be expected to consume 182 TWh/a primary energy in 2030. Due to the measures this can be reduced to 153 TWh/a (-29 TWh, -16%, of which 38% due to increased use of Ventilation Units). The largest savings (16.7 TWh or 58%) are obtained on the 1 mln installed fuel-fired air heaters (AHF), due to an increase in efficiency from 66% in 2015 to 82% in 2030, and due to heat load reduction by Ventilation Units.
Split heat pumps (AC splits rev) have the largest stock (3 mln units, 46% of total) but consume only 22% of the total energy of air heaters. Their contribution to the energy savings is 5.3 TWh/a (18%). Although rooftop heat pumps (AC rooftop rev) show a large efficiency improvement (122% in 2020 to 130% in 2030), their contribution to energy savings is modest (2.2 TWh/a or 7.6%), because the stock is much lower (162 thousand units or 2.5% of the stock in 2030). Variable refrigerant flow systems (AC VRF rev) are the only air heating products with increasing stock (0.9 mln in 2015 to 2.2 mln in 2030).
Their average efficiency will increase from 131% in 2015 to 144% in 2030, with a contribution of 4.6 TWh/a (16%) to the total primary energy savings in 2030.

SPACE COOLING, ELECTRICITY CONSUMPTION AND SAVINGS
The 8.8 mln installed (central) cooling products covered by regulation 2016/2281 consumed 151 TWh/a of electricity in 2020. For comparison: the separately regulated 46 mln (smaller) Room Air Conditioners consumed 12 TWh/a.
Although there are relatively few HT-PCH (4% of stock), they have high cooling outputs (ranging from 865 to 6375 MWh/a/unit), and as a result consume 65% (99 TWh) of the total electricity. Chillers represent 22% of the stock, have medium cooling outputs (25 to 900 MWh/a/unit), and are responsible for 21% of total electricity use for space cooling. Air conditioners (excluding RAC) represent 74% of the stock but have relatively low cooling outputs (9 to 40 MWh/a/unit) and therefore use only 14% of the electricity.
The measures on cooling products are expected to save 12 TWh/a of electricity in 2030, corresponding to 23 TWh/a of primary energy for the generation and distribution of this electricity (at PEF=1.9). Most of these savings (73%) are obtained on high-temperature process chillers.
