Thermal Energy Storage Strategies for Commercial HVAC Systems Summary Thermal energy storage (TES) systems shift cooling energy use to non-peak times.

Note that removing formwork when concrete is too cold or hasn’t reached desired strength, could damage concrete strength and surfaces and concrete might collapse. Using frost blankets and insulated formwork could be necessary to protect concrete.

Nov 28, 2018 · The Cost of Winter Concrete Construction. Winter concrete construction is costly, partly because the concrete mix costs more, but mostly because worker productivity is lower because of all the work involved in heating and insulating during curing, setting up extra work site lighting, and compensating for low air humidity.
These include, but are not limited to, the following: store the bagged concrete in a warm temperature before use, use warm (not hot) water to mix, and ensure that the concrete is protected from freezing for at least 48 hours using plastic sheeting, insulated blankets, or other means.
Cure concrete in cold weather without additional water; adding water will keep the concrete saturated so that freezing will damage it even after it reaches 500 psi compressive strength. Concrete in cold weather absolutely does need to be cured-the surface can dry out even faster than in warm weather, if the concrete is warmer than the air.

I can't find info anywhere to indicate if he is correct or just blowing smoke. What say some of you? Thanks in advance for any input.
