"---" indicates that no data was submitted for this field

Total floor area of building space:

2,065,165 Square feet

O+M Certified Space

Building space must be certified under a rating system focusing on the operations and maintenance of existing buildings (e.g. LEED O+M) to count as certified space for this credit. Sustainability in new construction and major renovation projects (e.g. LEED BD+C certification) is covered in the Building Design and Construction credit.

Floor area of building space that is certified at each level under a green building rating system for the operations and maintenance of existing buildings used by an Established Green Building Council:

	Certified Floor Area
LEED O+M Platinum or the highest achievable level under another GBC rating system	0 Square feet
LEED O+M Gold or the 2nd highest level under another 4- or 5-tier GBC rating system	0 Square feet
Certified at mid-level under a 3- or 5-tier GBC rating system (e.g. BREEAM-In Use, CASBEE for Existing Buildings, DGNB, Green Star Performance)	0 Square feet
LEED O+M Silver or at a step above minimum level under another 4 -or 5–tier GBC rating system	0 Square feet
LEED O+M Certified or certified at minimum level under another GBC rating system	0 Square feet

Floor area of building space that is certified under a non-GBC rating system for the operations and maintenance of existing buildings, e.g. BOMA BESt, Green Globes CIEB:

0 Square feet

Percentage of building space certified under a green building rating system for the operations and maintenance of existing buildings:

If reporting certified space, provide:

A brief description of the green building rating system(s) used and/or a list or sample of certified buildings and ratings:

Carleton currently does not pursue LEED certification for existing buildings.

If reporting uncertified space, provide the following:

Energy Management and Benchmarking

Of the institution's uncertified building space, what percentage of floor area is maintained in accordance with an energy management or benchmarking program? (0-100):

100

A brief description of the energy management or benchmarking program:

On an annual basis, Carleton engages Sightlines - a Facilities benchmarking company - to analyze campus data and benchmark Carleton's energy use verses a target group of peers with a similar institutional and climate profile. Benchmarking is done with both actual values and weather normalized. On a real-time basis, Carleton sub-meters each building for both heating and electricity. 15-minute interval data from the campus meters plus monthly utility bill information is automatically fed to a Lucid Building OS energy management information system (EMIS) which provides data visualizations and benchmarking information. An Energy Team consisting of the Manager of Campus Energy, the Maintenance Manager and 2-3 student sustainability assistants reviews the data on a weekly basis to identify anomalies which are then compared with building schedules and building automation system data to identify the source of the issue. Carleton also uses the building automation system to schedule HVAC systems according to building open hours and/or room occupancy. Meeting room and classroom schedules are adjusted weekly according to the campus calendar.

Water Management and Benchmarking

Of the institution's uncertified building space, what percentage of floor area is maintained in accordance with a water management or benchmarking program? (0-100):

100

A brief description of the water management or benchmarking program:

On an annual basis, Carleton engages Sightlines - a Facilities benchmarking company - to analyze campus data and benchmark Carleton's water use verses a target group of peers with a similar institutional and climate profile. On a real-time basis, Carleton has a water meter in each building which feeds the 15-minute interval data to a Lucid Building OS system described above.
