• You can not use defaults if you want a certified
ENERGY STAR score
• Data centers are larger facilities with > 75 servers and
separate CRAC; do not include server closets
• Some property use details that matter include
operating hours, computers, and percent heated

Pg. 82
Gross Floor Area Reminders
• Gross floor area is measured from exterior walls
• Not the same as leasable space
• Includes all common and tenant spaces
• Only include atrium base floor area
• Good idea to include skyway floor area – energy use
will be included
• Should be similar to the floor area on file with the city –
though not if portions of the building are exempt.

Technical Terminology for EBCx
• ReCommissioning and/or RetroCommissioning (RCx)
• Repair to, or optimization of, building operations (schedules,
procedures), equipment, facilities, or systems to primarily
enhance energy efficiency
• RCx generally focuses on major building systems (building
envelope, HVAC, and controls), targeting quick payback and
often, relatively quick turnaround, energy conservation
opportunities.

Efficient: Prioritize actions

EBCx’s Strategic Difference

Pg. 91
Support for EBCx
• National Study, 2009
• 186 project, various bldg types
• Average energy cost savings 10-15%
• Paybacks under 2 years

Cost and Greenhouse Gas Emissions. Berkeley, CA: Lawrence Berkeley National
Laboratory Report LBNL – 56637.

Pg. 92
Potential Scope of Existing Work
Article Highlights
+ 40% of all GHG come from building
sector
+ Survey in 2000 suggested that 0.03% of
existing buildings have been RCX
+ Half of all RCX is happening in California
+ RCX has potential to save $30 billion a
year and 300 million tons of GHG
emissions.

Pg. 121
Energy & Water Tips and Reminders
• You will need 13* bills covering all days in 2014
• *14 billing cycles if no meter start date
• Use the spreadsheet upload function in Portfolio
Manager
• Use indoor and outdoor water
• Steam units: billed in “MLBS” – which means
thousand pounds; this is the same as “kLbs” in PM
• If you have interruptible service and used propane or
diesel, you will need to include those fuels as well. Use
delivery dates and volumes that cover 2014.

Pg. 122
Obtaining Your Utility Data

Pg. 123
Obtaining Your Utility Data
• Must include all commercial spaces in the building
(including tenants)
• Tenants are required to provide data, according to City

(except for Xcel and you have more than 15 tenants).

Pg. 124
Obtaining Tenant Data Options
• Obtain signed release form and request from utility
• Ask for data directly from tenant
1. Tenant can provide bills

Note on CPE Usage Data
• If you buy your gas through a marketer, there is a
chance your total use will not be available by logging
in to the CPE site. If you show cost but not use, call
your CenterPoint account representative.

Pg. 136
Note on district energy costs
• If you decide to include cost, note that natural gas and
steam costs are not apples-to-apples
• NRG costs will include equipment and some O&M.
• You will be able to compare your building’s energy
costs to itself, but not across a portfolio of different
buildings on different fuels.
