Energize Denver
Unlocking Opportunity in Denver
Public Input Session
April 25, 2016
How are we doing?
• #9 on ENERGY STAR ranking of cities
• #10 on ACEEE ranking of cities:
– #1 on local government action
– #16 on buildings policy, our lowest rank
– #7 on utilities programs due to Xcel

Who Benefits?
Building Owners
= A More Valuable Asset(NPV of $40,000 per year is $424,000)
Studies by CoStar verify this.
Invest $100,000 in improved energy efficiency
Lower operating costs: $40,000 in annual energy savings
Increase Net Operating Income: $40,000 increase in income
Who Benefits?
Businesses
ENERGY STAR = 35% more efficient
$.50/sf savings
Attract business to Denver
Source: USEPA and Xcel Energy
• Energy efficient commercial buildings makes Denver more attractive to global firms
• Sustainability helped win Panasonic, “It made it a slam dunk.”
• Millennials want sustainability. Attracting millennials could attract business.
• Energy efficiency can help us beat our top competitor cities such as Salt Lake City and Dallas
Who Benefits?
A Globally Competitive City
Energize Denver Task Force GoalReduce energy consumption of commercial and multifamily buildings by
10% by the end of 2020 and double that in the following decade.

Taskforce
Goal is to Reduce
Energy
Consumption this
Much by 2020
• Double the 2020 goal by 2030 means another 3.8 million MMBTU reduction in
energy consumption by commercial and multi-family buildings by 2030.

higher) annually, if they qualify
– Incorporate LEED EB O+M into all
operations

16 other cities have these policies. They have seen 2-3% annual energy
savings, free tool, 4-5 hours to set up an account, 1-2 hours of staff time to
enter data annually.
High Performers are Celebrated and
Exempted from Further Requirements
High Performer Exemption from Further
Requirements: CertificationENERGY STAR or LEED certified in last 5-7 years.
ENERGY STAR certification costs $1-3k depending
on building size, LEED somewhat more
Celebrate High Performers!
Policies 3, 4 and 5
Flexible options for improving efficiency
Complete once every 5-7-years (14-20% of buildings each year;
starting 2019/2020; phase in by size, and/or random order.)
Policy 3: Performance Improve EUI by 12-15% from a 2016 baseline. (EUI weather adjusted)
Policy 4: RetrocommissioningBuilding “tune-up”. RCx study plus implementation.
Base building systems only in multi-family
Policy 5: Audit and UpgradeOwner completes an audit and implements measures from the audit with
<3 year payback OR implements other upgrades with similar savings
