Af few questions:

Best way to clean an 8 pass AHU cooling coil – high pressure washer, foam or install UV?Is it ok to schedule the operation of domestic hot water heaters?When shutting off large campus steam distribution systems during the non-heating season, should any special precautions be taken?What is the best Unit Ventilators control strategy to maintain comfort and save energy?What is the best way to optimize multi-zone air handling units?

Remember the Sewer Bill is typically based upon the amount of water consumed so saving water usage also reduced sewer bill

For water that is evaporated it should be metered separately so that it does not effect the sewer bill

Panels should be installed at an angle that is equal to the latitude (best angle for solar collection)

Mid December is when the sun is at its lowest elevation that is the ideal time to figure our when the shade will cover a panel

Jim Ridge - Best way to clean an 8 pass AHU cooling coil – high pressure washer, foam or install UV?

using a biodegradable cleaner and allow it to soak in and wash with regular hose

Chris Pimentel - In my town, we've just entered into an agreement for battery energy storage at an elementary school. It's a third party, demand response, peak shaving play (where they actually pay the town), and will not be available as an energy backup/resiliency measure. It appears to be a good deal for the town, but I'm not sure how well it works out for the owner of the system. Do you think this is going to work out for them, and if so, will this type of storage propagate at a good rate?

Thanks Michael! Your question will be next.

When co-sited with solar, C&I customers and residential customers are seeing 4-5 year paybacks by participating in Connected Solutions and leveraging the federal ITC and the SMART Battery adder.

Most DR events happen in the summer, while most outages (especially the life threating ones) happen in the winter. Customers can have their cake and eat it too!

Remember in Mass where the utilities do not manage the electic supply (they have been divested) The suppliers can justify the cost of batteries

Please google "Connected Solutions" if your are interested in either residential or C&I scale batteries. Or just call Paul 781 264 1360 !

Michael Makofsky - How can Energy Efficiency impact an optimal approach to educating customers about total cost of ownership?

Good energy efficiency typically can slow things down and allow the systems ramp up and down to meet load. Rather that turning on and off - The difference allow systems to last longer because the equipment is not hammering on and off!

Brian Crafts - What do you think is the largest hurdle (technological, political or financial) that needs to be overcome in order for cities and towns to meet long-term carbon neutral and zero net energy goals?

Correct on both points. Thx!

Jim Ridge - Is it ok to schedule the operation of domestic hot water heaters?

To build on Brian's question: what do you think of regulatory push for electrification such as the push in Rhode Island. Bluntly, if one can't guarantee me that power will stay on during a storm why should I not be concerned about the current state of distribution and transmission systems. If I lose my lighting is one thing but losing my heat And I can't charge my car to go buy white gas for my camping stove to cook a meal then I'm worried.

I should have said policy push (not regulatory)

How can I calculate exact numeric value, how much VFD save energy?(any formula to calculate)

Part of the move to full electrification needs to incorporate resilience through energy storage, distributed generation, redundancy, etc.

John - Question came up - How do folks get a recording of this meeting?

Hi Everyone, we will send out a link to the video recording of this meeting to all registered attendees at the end!

Thank you for your expertise this evening!

Thank you everyone,have good night

Thank you!
