Changes to infrastructure and behaviour at Hydro buildings support the environment

It’s important to continually re-evaluate common practices. Just because we have always done something a certain way, doesn’t mean it is shouldn’t be re-evaluated periodically to see if there is a better way to do it. It can be easy to fall into the comfort of familiarity, but at Hydro we continually challenge ourselves to improve, and now more than ever we are applying that attitude to improve the energy efficiency of our own operation.Two examples come to mind that demonstrate how our employees have not only adopted an energy conservation culture, but have been proactive about taking it to the next level. The first example is a cooling system for a server room at Hydro place was at the end of its life and required replacement. Instead of simply replacing the unit with a similar capacity cooling unit (which unfortunately is too common an occurrence in any organization), the IT department contacted our Internal Energy Efficiency Advisor at the time to enquire whether there were any opportunities to improve the system’s efficiency. There were no perceived issues with the existing cooling system, but regardless the question was asked if it could be made more efficient. A third-party analysis was performed on the cooling load and it turned out that as a result of upgrades and improvements to server efficiencies over the years, the cooling load was less than half the initial design load. The existing cooling system was replaced with a smaller one more appropriate for the load, reducing replacement costs and improving the seasonal efficiency of the system. The second example is a recent one, where personnel responsible for the operation of Hydro Place followed-up on a mass email sent out to inform that our engineering department would be attending an off-site meeting. As the engineering department occupies nearly an entire floor, Hydro Place facility personnel investigated whether the HVAC systems serving their area could be placed in unoccupied mode to conserve energy. This level of attention to day-to-day, floor-by-floor occupancy and schedules exceeds conventional operating practices for commercial facilities. There are so many more examples of our people sincerely embracing our energy conservation culture, but those two examples really stick out because of how they were the result of individuals taking it upon themselves to be proactive.The focus for Hydro’s internal initiatives in 2012 is on expediting the phase out of T12 fluorescent lighting, evaluating more efficient options for older high-intensity discharge (HID) lighting, installing controls to automatically setback heating systems in support buildings, and performing energy walkthrough audits of our sites to identify other opportunities. These are exciting times for our energy conservation initiative, our people are onboard, we are analyzing our sites for energy conservation opportunities, we’re testing new technologies and operating strategies for our facilities to eventually standardize across Hydro. It all adds up to significant steps in the right direction.
