Using emission factors applied in the inventory, the current report takes the emission inventory one step further by preliminarily allocating emissions by faculty. This has successfully been accomplished by other North American institutions, such as the University of Harvard in Massachusetts (Martin, 2008).  Currently, UBC does not bill individual faculties or departments for the energy they consume. This lack of accountability raises various challenges. In addition to difficulty in the financial management of UBC utilities, there are no incentives for energy conservation, nor are there penalties for utilities consumption on the departmental level.  Thus, although UBC as a whole may be committed to sustainability initiatives, these may not be carried out on the smaller faculty or departmental scale. By helping to identify major faculties’ approximate contributions to UBC’s GHG emissions, this report aims to focus the efforts of the UBC Sustainability Office in applying its conservation and educational strategies to the largest GHG-contributing faculties. Additionally, this report provides the initial step towards accurately allocating and billing individual faculties and departments for their energy consumption.  The 2006 UBC Greenhouse Gas Inventory Report successfully identified UBC’s GHG emissions based on 3 scopes in following with the World Resources Institute (WRI) guidelines (Rouhany, 2009). The results in Figure 1 confirmed the highly significant (~86%) contribution of natural gas, primarily from steam production, to UBC’s GHG Scope 1 (direct) and 2 (indirect, electricity) emissions. Electricity was shown to also play a strong, albeit secondary, role (~8%) in contributing to Scope 1 and 2 emissions. Hence, this study has focused on the GHG emissions resulting from steam and electricity consumption.        Figure 1.

I. Scope The University of British Columbia (UBC) is composed of four campus locations: UBC Vancouver, Robson Square, UBC Okanagan, and the Great Northern Way campus (Rouhany, 2009). For simplicity, this report scrutinizes the division of greenhouse gas contributions from faculties on the main UBC Vancouver campus only. Robson Square provides numerous public lectures and UBC and community bookings that benefit various populations and would be difficult to attribute to specific faculties. UBC Okanagan has 7 faculties and services 5,325 students and 353 faculty members (UBC, 2008b). Although this population is small compared to UBC Vancouver’s November 2007 count of 44,161 students, it is recommended that UBC Okanagan be included in the faculty analysis in future follow-up studies (UBC, 2008a).  Within the UBC Vancouver campus, the six largest faculties by student population have been targeted for analysis. These include, in order of decreasing size: • the Faculty of Arts, • the Faculty of Science, • the Faculty of Applied Sciences, • the Faculty of Education, • the Faculty of Medicine, and • the Sauder School of Business (commonly known as the Faculty of Commerce) (UBC, 2008c).  As previously mentioned, this analysis has been limited to the allocation by UBC faculty of Scope 1 and 2 emissions. Even more specifically, this preliminary report currently only examines the natural gas (from steam production) source in the direct GHG Scope 1 emissions and the indirect electricity Scope 2 emissions generated off-site and consumed at UBC. These scopes are further detailed in Table 1, which corresponds to the definitions provided in the 2006 UBC GHG Inventory Report.       UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 6Table 1. GHG Emission Scope Definitions based on the World Resource Institute (WRI) and the World Business Council for Sustainable Development  (Rouhany, 2009)  Definition of Scopes for GHG Emission Inventories Scope 1: Direct GHG Emissions Direct GHG emissions occur from sources that are owned or controlled by the institution, including but not limited to emissions from combustion in stationary sources (fuel, oil, natural gas), campus transportation and fleet vehicles, emission from livestock, and refrigerants. Scope 2: Electricity Indirect GHG Emissions Scope 2 accounts for GHG emissions from the generation of purchased electricity consumed by the institution. Purchased electricity is defined as electricity that is purchased or otherwise brought into the organizational boundary of the company. Scope 2 emissions physically occur at the facility where electricity is generated. Scope 3: Other indirect GHG emissions  Scope 3 is an optional reporting category that allows for the treatment of all other indirect emissions. Scope 3 emissions are a consequence of the activities of the institution, but occur from sources not owned or controlled by the institution. Some examples of scope 3 activities are: • Transportation and commuting (public transit and commuter traffic) • Institutional air travel • Fertilizer application • Waste generation and disposal • Embodied energy found in new construction and existing buildings and infrastructure,  • Use of purchased materials such as paper • GHG emissions associated with the production, transportation, consumption, and disposal of food sold on campus    UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 7II. Methodologies The overall approach used to calculate the greenhouse gas emissions contributed per faculty at UBC involves the multiplication of building ground areas by certain approximate steam and electricity consumption factors. The results are then multiplied by emission factors used in the 2006 UBC GHG Inventory Report. Finally, in order to account apply a weighting factor to account for differences in number of students and faculty served per faculty, the annual greenhouse gas emission rates per faculty are divided by the corresponding population.  The consumption factors were provided by the University of British Columbia Sustainability Office. These factors are 16.4, 23.0, and 1.9 kWh/ft2/year for electricity, steam, and natural gas consumption, respectively. In addition, the factor of 82.0 lbs of steam consumed per ft2 per year was also used. Currently, it has been assumed that steam is used in all buildings, so the natural gas factor was not used. However, natural gas and oil are also used instead or in conjunction with steam in numerous buildings, which is recommended for inclusion in further analyses.  The emission factors taken or calculated from the 2006 UBC GHG Inventory Report are 0.000024 and 0.000179 tonnes of equivalent carbon dioxide (CO2e) per year per kWh associated with electricity and steam, respectively. Equivalent mass of carbon dioxide (CO2) is used in order to account for the global warming potential of other harmful major greenhouse gases, such as methane (CH4) and nitrogen oxides (NOx).  Building Areas The attribution of buildings to faculties is a complex issue, as multiple faculties may use the same building, which further changes depending on the time of year. Thus, generalizations were first made using the highly simplified Campus Zone Map provided by UBC Classroom Services. In this map, the North East zone is attributed to Arts, the Central Northeast zone is linked to Science, the South West zone represents Applied Sciences, the Central South West and South South East zones are Education, the South East zone is Medicine, and the Central North West zone is Commerce.  Although these zones are partly accurate, by contacting representatives from each faculty and by researching buildings individually, it was revealed that faculties tend to use buildings scattered around campus (UBC Library, 2008; UBC Classroom Services, 2009a). Buildings within the aforementioned zones are often used for more general UBC services, such as the Student Union Building (SUB) in the Arts zone. Such buildings shared by many faculties, including most libraries, were excluded from the UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 8analysis, as they are assumed to be used equally by all faculties. It is recommended that the general services buildings are later incorporated into the analysis, with weighting factors based on the number of students or even actual student usage data, if available.  Some large buildings of note in which significant assumptions were made in the attribution to faculties include the Michael Smith Laboratories (Science), the War Memorial Gym (Education), the Life Sciences Centre (Medicine), the Koerner Hospital Pavilion (Medicine), and the Woodward Instructional Resource Centre (Medicine). Although these buildings are often used in great part by other faculties or even the public, in the case of the hospital, they have preliminarily been attributed to the aforementioned faculties as a starting point. This may be later subdivided with improved building use information. Furthermore, although some of these buildings are only used in small part by the faculty, such as the Acute Care Unit in the Koerner Pavilion, these facilities tend to be very energy-intensive. This is unaccounted for by the conversion factor and is expected to help offset the assumption of entire building usage by single faculties.  On a similar note, it is emphasized that the area-based method of calculating energy and steam consumption does not at all take energy intensiveness into account. Laboratories and clinics, such as the Acute Care Unit, are expected to require significantly more energy than typical classrooms (UBC Classroom Services, 2009b). It is suggested that this is later taken into account using an average factor, or better yet, implementing actual metered consumption data. Similarly, key factors such as building height (size of facility vertically, as opposed to only horizontally) and conversation habits of building users, such as turning off lights and computers after hours, will not be reflected by this analysis. Metered data is strongly recommended in order to improve accuracy and to better reflect the effectiveness of energy conservation efforts.  The faculties to which buildings were attributed include the Faculty of Arts, the Faculty of Science, the Faculty of Applied Sciences,  the Faculty of Education, the Faculty of Medicine, and the Sauder School of Business. These includes various departments, such as Human Kinetics (Education) and Nursing (Applied Sciences), with a more detailed list of UBC faculties and departments available online (UBC, 2009). Other relatively large faculties not accounted for, but recommended for further analysis, include the Faculty of Law, the Faculty of Land and Food Systems, the Faculty of Pharmaceutical Sciences, the Faculty of Forestry, and the Faculty of Dentistry. The latter, for instance, is suspected to be relatively energy-intensive because of the high frequency of clinic use. UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 9Student and Faculty Populations The number of students and faculty associated with each faculty was calculated from 2007 data provided by the UBC Office of Planning and Institutional Research (UBC, 2008c).   For students, undergraduates and graduates were included. Differences in part-time and full-time studies throughout the seasons were accounted for by taking the full-time equivalent (FTE) number of students based on a 30-credit course load for undergraduates and annualized over three terms (summer, winter term one, and winter term two) (UBC, 2008c).  For faculty members, those qualifying as “full-time” and reported to Statistics Canada in October were taken into account (UBC, 2007). Other staff members were not included in this analysis. UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 10Results and Discussion   The main objective of attributing UBC campus buildings to different faculties of determining corresponding electricity and steam consumption values is detailed in the Appendix. This list is a preliminary attempt at generalizing the use of buildings by faculties. Changes will have to be made to split usage of certain buildings between multiple faculties, such as the Life Sciences Centre (Medicine, Dentistry, Science, and others), the Koerner Pavilion (Medicine, Dentistry, Applied Sciences, and others), and the Institute for Computing (Science and the Faculty of Applied Sciences).  The total Scope 1 emissions for all 6 faculties assessed are 23,079 tonnes of carbon dioxide equivalent (CO2e) per year, which represents only 48.8% of the actual Scope 1 emissions quantified in the 2006 UBC Greenhouse Gas Inventory Report. This discrepancy may be accounted for in great part due to the exclusion of shared service buildings (such as most libraries, recreational facilities, and UBC Plant Operations and Utilities) and buildings used by smaller faculties. Moreover, this analysis has not accounted for oil and natural gas combustion, livestock emissions, and refrigerants.  The Scope 2 emissions for all 6 faculties analyzed amount to 2,206 tonnes CO2e/yr, which represents a high 78.9% of Scope 2 emissions. This closer correspondence between the current analysis and the 2006 UBC Greenhouse Gas Inventory Report results may be due to a more representative emission factor. Additionally, Scope 2 emissions are solely attributable to a single source: electricity. It should be noted, as in the inventory report, that using the current BC Hydro emissions factor of 24 tonnes CO2e/GWh instead of 84 tonnes CO2e/GWh would reduce the Scope 2 emissions by over 70%. However, the emission factor of 84 tonnes CO2e/GWh was used in order to better account for the higher greenhouse gas intensity associated with the importation of electricity (Rouhany, 2009).  The results from the analysis of the information in the Appendix are summarized in Table 2. As shown in Figure 2, the top three greatest GHG-contributing faculties are Medicine, Science, and Applied Sciences at similar values of 26.4%, 24.3%, and 22.3%, respectively. These results are anticipated, as these faculties typically require the most laboratories, which require large areas, steam demand, and electricity requirements. For Medicine, the high contribution calculated may be attributed to the large areas of buildings such as the Life Sciences Centre and the Koerner Pavilion. However, clinical and laboratory activities in such buildings would be expected to be energy-intensive, which may partially offset the UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 11simplification of attributing the entire buildings to the Faculty of Medicine. Similarly, for the Applied Sciences, the simplification of the Forest Science Centre allocation as an Applied Science building may be offset by the energy-intensive activities unaccounted for in such facilities as the Civil & Mechanical Engineering (CEME) Laboratories and the Chemical and Biological Engineering (CHBE) buildings.

This relative ranking is expected, based on the student and faculty populations summarized in Table 1, in which Arts has over 13,000 people, Education accounts for roughly 3,700, and Commerce makes up under 2,900. Additionally, Commerce is expected to have a very low contribution, especially in this area-based analysis, as their classes are almost exclusively conducted in the Henry Angus Building, with some offices more recently in the Donald Rix Building.  The results from Table 2 and Figure 2 suggest that utilities conservation initiatives should be focused on the Faculties of Medicine, Science, and Applied Sciences. Because of the large building areas associated with these faculties, steam heating method optimization would be expected to be very beneficial. Additionally, technological sustainability initiatives ranging from lighting to computers to laboratory equipment are anticipated to have a larger impact on these faculties than on others, assuming that the current level of potential for energy utilization improvement in all faculties is similar. This analysis suggests that equal billing among faculties would not be representative of energy consumption.  Further examining the number of students and faculty tallied in Table 2, the total of 36,370 full-time equivalent (FTE) students and FT faculty corresponds to a high value of approximately 96% of UBC Vancouver’s total 2007 FTE students and FT faculty of 37,904, summed from data provided by the UBC Office of Planning and Institutional Research (UBC, 2008c). Overall, Arts and Science, constituting 13,393 and 8,370 people, respectively, account for a significantly larger number of faculty and students than the other faculties. The remaining faculties ranged relatively narrowly in number from 2,893 to 4,328 students and faculty.  Because of this large difference between student populations in Arts, Science, and the other faculties, the contributions have been weighted per capita in Figure 3. Examining this greenhouse gas emission intensity per capita, the significant contributions from Medicine becomes more pronounced at 35% due to the faculty’s relatively few students and faculty. While the Applied Sciences increases its contribution slightly to 25%, the high population of Science brings its contribution down to 14%. Thus, Science is comparable to Education (12%) and even approaching Commerce (9%). Finally, because of the Faculty of Arts’ substantial number of students and faculty, it has the lowest contribution to greenhouse gas emissions per capita of 5%.  UBC 2006 Greenhouse Gas Inventory Faculty-Specific Preliminary Analysis 13 Figure 3. Faculties’ Estimated Relative Contribution Percentages to UBC Greenhouse Gas Emissions on a “per capita” Basis for each Faculty  Similar results are provided more quantitatively in Figure 4. These results show that approximately 1,800 kg of CO2e are emitted per capita per year in Medicine, compared to only roughly 240 kg CO2e/capita/yr for the Faculty of Arts. Then again, these values do not yet include shared UBC services, which would be anticipated to increase the values for all faculties significantly if incorporated into the analysis.  The results from Figures 3 and 4 indicate that, although there may be more students in the Faculties of Arts and Science, the greenhouse gas emissions per capita for the Faculties of Medicine and Applied Sciences are more significant. Thus, it is recommended that sustainability awareness and education endeavours may be more effective in Medicine and Applied Sciences.

The accuracy of the results are limited due to the methodology of converting building areas into energy consumption and then into equivalent corresponding emissions. Furthermore, the validity of the results are limited by the difficulty and complexity related to allocating buildings to specific faculties. However, the results show a rough relationship between the relative contributions of the major faculties, upon which future studies may build to increase the accuracy of the results.  The relative percentage contributions to the UBC greenhouse gas emissions for the Faculties of Medicine, Science, Applied Sciences, Arts, Education, and Commerce were 26.4%, 24.3%, 22.3%, 12.6%, 9.0%, and 5.4%, respectively. Dividing the emissions by the student and faculty populations for each faculty, the results are shifted. The relative percentage contributions to the UBC greenhouse gas emissions intensity (per capita) for the Faculties in the same order of Medicine, Science, Applied Sciences, Arts, Education, and Commerce become 35%, 14%, 25%, 5%, 12%, and 9%, respectively.  These sets of results show that the Faculties of Medicine, Science, and Applied Sciences should represent the focal point of energy and utilities conservation and optimization efforts. Furthermore, these results suggest that the UBC and the UBC Sustainability Office may benefit most from focusing on the education of the Faculties of Medicine and Applied Sciences regarding sustainability and “green” initiatives and habits. It is evident from the results that faculties should not be billed equally for energy consumption, but equitable billing allocation would require increased accuracy in the results.  For future studies, it is recommended that buildings be sub-divided into multiple faculties, depending on their usage. This should be ascertained in consultation with each faculty. Additionally, it is recommended that shared services and buildings that are not faculty-specific be included in subsequent studies in order to obtain more accurate absolute intensity results. Data from the 80 currently metered buildings on campus should be incorporated as much as possible into the methodology to confirm and improve the accuracy of the results. For buildings lacking specific metered data, a factor for energy intensiveness is suggested to account for higher laboratory and clinical energy demands.
