Our client is a polytechnic institute offering more than 110 career programs in technology, trades and business. Established in 1916, it is Calgary’s second oldest post-secondary institution and Canada’s first publicly funded technical institute. With its wavy roof and walls of glass, it is a stunning landmark and the largest building in Trades and Technology Complex, adding 440,000 square feet of leading-edge classrooms, labs and gathering spaces to campus. The gas and steam costs are much closer than expected. Each winter, there are many periods of time that there is more heating demand from the building than local boilers can supply. Boiler output from specification may not be a realistic high limit that the building automation system could use to determine when the switchover is most optimum. Running with more conservative lower limit around 250 kWh, control system switches to the more expensive steam heating from central plant usually too early, and end up using more expensive steam than local boilers for heating than necessary.
Kaizen traced the maximum output steadily from local boilers to be consistently over 550 kWh. This is the actual output for the building application with all factors that affect boiler performance considered. This can be projected with little deviation of boiler performance in the next winter much more optimally.
Steam heating goes from nearly half of the winter to just a few days with very low temperature close to –30°C. Kaizen estimated a cost potential saving of over CAD $12,900 per year for running more efficient local boilers and less more expensive steam from central plant without undersupplying heat for the high building demand. This is equal to around 129,000 kWh of energy saving or an equivalent 91,400 kg of CO2 gas emissions reduction. In context, that is the amount of gas emitted from 10,287 gallons of gasoline consumed.
