quick electrical connectors instead of wire connectors, which makes replacement faster, simpler and safer. The steam to hot water conversion significantly reduced maintenance needs by eliminating more than 300 steam traps. The project design also aimed to reduce the level of required supervision of the plant by qualified operating engineers. To achieve this, the three gas boilers were downrated from 60 MMBtu/h to 45 MMBtu/h (17.6 MW to 13 MW), and one of the four new chillers was installed away from the three others. The two 200 ton (703 kW) heat pumps were installed in another mechanical room, closer to the heat recovery loads and summer heating loads. All this reduced required supervision to one hour per 24 hours, rather than continuous 24-hour supervision. Maintenance personnel are now freed up to do maintenance on the site and ensure the systems are operating efficiently. Sustainability The project's exemplary GHG reduction of 57% is important in light of the province's carbon reduction targets and is used as an illustration of what can be achieved. It must be noted that the electricity grid is already very clean in the province of Quebec because of its hydroelectric power plants, so most of the GHG reduction is linked to decreased use of natural gas. Lean construction practices were implemented to minimize waste. All equipment and piping that was inspected and deemed to be in good condition was reused whenever possible.
