church controls / low occupancy

Bill Fries

I’m working on a church that is adding a multipurpose room (gym) to get kids involved plus a nursery, a couple of classrooms, kitchen, and a nursery. They want the building air conditioned with rooftop units. I recommended to the architect installing a boiler for baseboard, cabinet unit heaters, and radiant ceiling panels (entrances). I just thought why heat the space with rooftop units and we can make the building comfortable in low-occupancy.

All radiation, ceiling panels, cab heaters, are piped with zone valves, but I am wondering what is the best way to keep costs down. DDC controls in a church that no one can use?.

I could pipe the building with 3 zones, then use set back stats.

Any suggestions for controls for a church that is HIT or MISS with occupancy?

Everything is still on the drawing board.

Thanks for the help (churches are different)

church radiation

I’m working on a church in Michigan that is adding a multipurpose room (gym) to get kids involved plus a nursery, a couple of classrooms, kitchen, and a nursery. They want the building air conditioned with rooftop units. I recommended to the architect installing a boiler for baseboard, cabinet unit heaters, and radiant ceiling panels (entrances). I just thought why heat the space with rooftop units and make the building comfortable in low-occupancy.

All radiation is piped with zone valves, but I am wondering what is the best way to keep costs down. I hate to put DDC controls in a church that no one knows how to use.

Any suggestions for controls for a church that is HIT or MISS with occupancy?

Everything is still on paper.

Ventilation

is going to be the most signifcant design constraint, not heat. In a gym/multipurpose room, the occupancy can be very dense and obviously varying greatly in activity. The IMC requires 15 cfm/person in an Auditorium environment, 20/person in a Gym (playfloor) environment. A heated makeup air unit and exhaust fans will be required, at a minimum. If the kitchen is non-residential in any way, exhaust and makeup air will also require competent HVAC engineering. You mentioned a nursury, which will also have specific ventialtion requirements. Hire a PE. Churches are different, but not that different. In most jurisdictions in which I have designed HVAC systems for churches that included classrooms and/or nursuries, the sometimes lax constraints on churches did not apply.
