U89 PAC 03 and PAC 04 Replacement
2320 Lester Road
Building U89
Ottawa, Ontario
OBJECTIVE:
The two roof top ventilation units have surpassed their life-expectancy and
require replacement. We will be replacing the two ventilation units for similar
units with a higher efficiency and a few nuances. One unit will incorporate a heat
recovery capacity allowing us to capture the washroom exhaust to supplement
the heating demand.
BACKGROUND:
The ventilation units are original to the building, one unit original to the original
building from 1977 and the other original to the additional from approximately
2001. One unit no longer operates and the other unit operates inefficiently when
load is applied. Therefore, replacement is required.
TASKS AND DELIVERABLES:
Demolish two roof top units and remove from site
Provide new openings to accommodate the change in size of ventilation
Provide new steel structure to support PAC04 c/w roof top curbs (both PAC03 &
04)
Install new roof top units
Ventilation network needs modification from PAC03
Complete ventilation connections
Tie in to BAS
Provide new F/A device for PAC04
