Great idea, Chris. We could use phase change material to store heat at "normal" condensing temperature with no energy penalty during the day, then have it available to a heat pump overnight ... (More)

I tend to think of chilled beams in patient rooms. No doubt they can work there. What other parts of a hospital are well served by chilled beams? For those areas not suited, what are the rea... (More)

I think there is a perception that chilled beams are more expensive than VAV systems. Do you have some data on cost relative to other systems? I think it would be helpful to show real-world ... (More)

In Breakout Room 1, our top conclusions were: We have lots of heat that can be stored and re-used. Storage technologies can help with diurnal swings Retrofit is much more complicated than... (More)

From our Workshop breakout room today: Move to decentralized systems, such as chilled beams, variable refrigerant flow  - maybe reduce fan energy and need to reheat. Does it help if we mov... (More)

This question comes up a lot when we talk about electrification. I think it's actually not as big an issue as it may seem. First, the goal is tor reduce loads. That should always be the sta... (More)
