    Effective January 1, 2023, cooling products will be subject to regional minimum efficiencies, according to Seasonal Energy Efficiency Ratio 2 (SEER2). New M1 testing procedure [7] is designed to better reflect current field conditions. DOE increases systems' external static pressure from current SEER (0.1 in. of water) to SEER2 (0.5 in. of water).

    The electric grid is made of up electric transmission and electric distribution, with electric production by itself averaging about 44% of the cost nationally. [31] As of 2019, transmission costs are the fastest-growing part of the bill, and Transmission Access Charges (TAC) are applied regardless of how far electricity travels across the grid.

    IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
