A brief description of when and why the building energy consumption baseline was adopted:
---

A brief description of any building temperature standards employed by the institution:

The buildings heating systems all run off of a Weekly and Annual Schedule. When the building are occupied - anywhere between 7:00am and Midnight - they are given a room temperature average set-point of around 22 degrees C.
When the buildings are unoccupied - night-time or holidays - the room temperature average set-point is around 18 degrees C.


A brief description of any light emitting diode (LED) lighting employed by the institution:

Lansdowne Campus:
Fisher 100 Lecture Room - all LED.
Fisher Outside Pathway - all LED.
Cultural Center - all LED.
LRC - some LED
Dunlop - recent LED upgrade to part of building.
Miscellaneous - pot light with dimming compact florescent bulbs are replaced with LED when they burn out.

Interurban Campus:
Miscellaneous - pot light with dimming capable compact florescent bulbs are replaced with LED when they burn out.

Note:
Most new lighting projects use LED lighting where applicable.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Lansdowne Campus:
Some occupancy sensors throughout the campus.

Interurban Campus:
Technology building - classrooms
C.B.A. building - classrooms
Campus Center - some classrooms and some offices.

Note:
Most new lighting projects add occupancy sensors.


A brief description of any passive solar heating employed by the institution:
---

A brief description of any ground-source heat pumps employed by the institution:
---

A brief description of any cogeneration technologies employed by the institution:
---

A brief description of any building recommissioning or retrofit program employed by the institution:

Camosun just completed a B.C. Hydro Continuous Optimization Program at the Interurban Campus.
This was a Building Automation System and HVAC hardware and software/programming upgrade to Campus Center, Technology building, CBA, Drysdale, and the Jack White building.

- replaced all of the old DDC room controllers in CBA and Campus Center
- replaced all non-functioning DDC related devices in all 5 buildings
- re-wrote most of the DDC programming in all 5 buildings to reduce equipment run-times and optimize comfort and efficiency.


A brief description of any energy metering and management systems employed by the institution:

Interurban Campus:
All buildings have Power Metering Equipment that are interfaced to the DDC system. The 5 main buildings are part of an energy report that is submitted monthly to the Facility Management Director and Associate Director.

Lansdowne Campus:
All buildings have Power Metering Equipment that are interfaced to the DDC system.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

When aging or malfunctioning equipment is due for replacement it is generally replaced by a higher efficiency product. Some examples are :

- old Boilers replaced by high efficiency Condensate Boilers.
- as stated old lighting is replace with LED or higher efficiency fluorescent lighting - original T-12 fixtures replaced with T-8 or T-5 fixtures etc.
- heating and cooling pumps that would needlessly run at full capacity have had Speed Drives added to their control to vary their output based on demand.
- air handling units have had Speed Drives added to their control as well.
- there are areas that have had Heat Exchangers added to recover and reintroduce heat from exhaust systems back into the buildings.


A brief description of any energy-efficient landscape design initiatives employed by the institution:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
---

A brief description of other energy conservation and efficiency initiatives employed by the institution:

- Facility management building has a solar array that feeds power back to the grid and charges battery powered tools and golf carts used by the ground keepers.
- Drysdale building has a Solar Wall that takes the solar heated water and introduces it into the building hot water system.
- Helmut Hubert has a Heat Exchanger that pulls otherwise wasted heat off of the freezer cooling compressors and introduces it to the building hot water system.
