Energy, Resources, & Greenhouse Gases Data Management

Human activities, such as the burning of fossil fuels, create emissions now referred to as "Greenhouse Gases" (GHG). Canada contributes only 2% of the world’s total greenhouse gas emissions. However, Canadians are the globe’s highest emitters, on a per capita basis. One of the major impacts on the earth’s climate is the manner in which GHG can impact on global weather patterns.

Canada’s Council of Ministers of the Environment has made commitments to stabilize Canada’s GHG emissions and to develop sustainable options to achieve further progress in the reduction.

Before any organization can implement conservation measures and begin to minimize GHG emissions, it is necessary that they establish a baseline of knowledge with respect to annual consumption.

For almost 15 years, the environmental health and technology scientists of C5 Plus Ltd. have been documenting and interpreting data concerning the consumption of electrical energy, natural gas and water by several of Calgary’s premier office buildings, including those managed by Brookfield Properties Limited, Oxford Properties Group Inc. and 20 Vic Management Inc. Baseline data presentations include natural gas, electricity and water consumption per leasable unit area and calculation of contribution to global GHG.

Natural gas, in modern office towers, is primarily used for heating the ventilation air in the winter season and also for wash room and restaurant use. The number of Giga Joules (GJ) of natural gas used by a building is a function of the physical characteristics of the building (e.g, curtain wall, floor area and number of heating degree days (HDD)). Typically, C5 Plus Ltd. will analyze the natural gas consumption data and establish a mathematical description in terms of HDD and GJ consumption.

For ventilation purposes, most modern office towers must heat outside air in the winter, and cool outside air in the summer, in order to maintain an acceptable comfort level for their tenants. This requires an expenditure of considerable amounts of natural gas and electricity. Industry (ASHRAE) guidelines imply that the ventilation rate per occupant should not be less than 20 cubic feet of outside air.

The environmental health and technology scientists of C5 Plus Ltd. are routinely measuring the ventilation rates on individual floors of the towers of out clients. This measurement is included in our Communicair IAQ management services. Our assessments often conclude that the office building is supplying much more ventilation air than is recommended under the industry guideline.

In the year 2000, C5 Plus Ltd. conducted a survey of energy and water consumption by 75% of Calgary’s downtown office buildings.

C5 Plus Ltd. has been successfully providing this technology for several years. For more information please contact us via e-mail or at our Calgary office - Telephone: 403-215-0040; Fax: 403-294-0959.
