Project Description

UBC Hospital Thermal Energy Supply

Koerner Pavilion

Space heating and domestic hot water were originally generated by three gas-fired boilers. Two new hydronic condensing boilers were added, in a cascading configuration with the original boilers, to raise the capacity and efficiency of the plant, enabling the Purdy and Detwiller pavilions to also be heated by the large hydronic boiler plant in Koerner.

The Koerner Pavilion originally utilized campus steam for humidifiers, kitchen equipment and medical equipment (sterilizers, cart washers, etc.) via a 150mm (6 in) high pressure steam line which delivered steam to the building. This was replaced with a steam boiler plant in the Koerner Penthouse comprising three steam boilers with economizers. The new system tied into the existing pressure reducing station, providing steam at the same pressure as the campus plant. Because of the water treatment technology used, no chemical water treatment is used in the steam plant.

Detwiller Pavilion

Space heating and domestic hot water were originally provided by steam-to-hot-water converters connected to campus steam. Humidification was also provided by campus steam through steam distributors mounted in each air handling unit. The upgraded system uses water-to-water converters to provide space heating and domestic hot water. Humidification was disabled as it was no longer necessary.

Purdy Pavilion

Space heating and domestic hot water were originally provided by steam-to-hot-water converters connected to campus steam. Humidification was provided by campus steam-through-steam distributors mounted in each air handling unit. Kitchen equipment was also connected to campus steam. The upgraded system uses water-to-water converters to provide space heating and domestic hot water. Humidification was disabled as it was no longer necessary. Some steam consuming terminal units had to be replaced with hot water equivalents. The kitchen was re-fitted with equipment that generates its own steam using electricity.
