Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	15,714,764 Kilowatt-hours	53,618.77 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	597,025 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

650,643.77 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

6,510,284 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Jan. 1, 2010	Dec. 31, 2010

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

First year with complete data for all energy consumption on main and south campus.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.07 MMBtu per square foot	0.09 MMBtu per square foot
Baseline year	0.10 MMBtu per square foot	0.12 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

21.00

Optional Fields

Documentation to support the performance year energy consumption figures reported above:

---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

---

A brief description of energy use standards and controls employed by the institution:

The campus Central Energy Management & Controls System (CECMS) is programmed with building operating schedules that control the HVAC systems. The Air Handling Units turn on in the morning and off in the evening as commanded by these schedules. Individual thermostats are not common as they do not fit in with the energy management practice of centralized HVAC control which is tasked to operators at the campus Central Plant.
Building temperature standards are regulated by CSU Executive Order 987 and the CSU Sustainability Policy.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

---

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

---

A brief description of co-generation employed by the institution:

At SJSU's Central Plant, the university owns and operates a highly efficient Cheng Cycle Cogeneration unit with a capacity of 6 MW. This consists of a natural gas fired turbine and a Heat Recovery Steam Generator (HRSG). On an annual basis, Cogen provides about 80% of the electricity for campus and nearly 100% of the steam load for building space heating and domestic hot water.

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

Continuous monitoring based commissioning has been used for several of our buildings with the plan to eventually do all of our buildings and keep the buildings on a 5 year schedule.

Equipment purchased must Energy Star rated and IT equipment must be EPEAT
