sunlight-reflecting “cool walls” could save as much or more energy than reflective cool roofs. There's no formal universal definition of what constitutes a “cool wall," said Ronnen Levinson, study co-author and staff scientist at Berkeley Lab. percent for single-family homes, and 4.6

Heating or cooling the interior cabin of an EV substantially affects the vehicle’s on-road efficiency, and the HVAC system often gets the proverbial “rented mule” treatment. Furthermore, the heating system exacts no penalty on range for the ICE vehicle, but definitely increases energy consumption in an EV.

The data seems to indicate that infections occur in dense inside areas with shared airspace, compounded by recirculating that air — the definition of a modern office building. . But with more outdoor air, the energy to heat and cool that air also will increase. . Suddenly you're having to condition all that [outdoor] air.

So, definitely look for far more specialized hardware. This is a technique that Google talked up in April, but it’s not yet widely used, and it will require attention to new cooling designs to keep the facilities from running too hot as well as memory components that can respond dynamically when a facility goes in and out of sleep mode.

So, the electric motors are unique to Rivian in terms of how they’re integrated into our drive unit assembly, how they’re mounted, how the inverter connects with them, how the cooling connects with them, and how they’re oriented in our gearbox. The motor and inverter has a water-glycol circuit to cool the stator and the power electronics.
