2030 DISTRICT 2014 ANNUAL REPORT

Denver’s High Performance Building District WHY THE DISTRICT 2030 Districts form out of the communities they What makes the district concept unique and serve. They rise up because of a shared vision of important is that it leverages the performance of the future where high performance buildings are our urban core as a district rather than individual the foundation for economic vitality. The Denver buildings. This allows Denver and our local building 2030 District has positioned our city as a beacon industry to share a common set of performance 45 Buildings for efficient resource use around energy, water targets and metrics. It allows us to benchmark and transportation and the market and economic and improve our city as a whole and to share development that results from investments in high best practices and work together to achieve - a total of - performance. The 2030 District catalyzes Denver’s our common goals. It also allows us to leverage national leadership position that is also visible in our economies of scale to provide unique benefits and exemplary ENERGY STAR and LEED buildings. opportunities to Denver 2030 District members. 20 Million s.f. The 2030 District is led by the private sector, 2030 Districts are designated urban areas primarily by the building owners and managers that committed to meeting the energy, water and comprise the district. And while it is private sector transportation emissions reduction targets of the led, the support the District gets from the City of 2030 Challenge for Planning developed by the Denver and local community groups such as the building industry nonprofit, Architecture 2030. Downtown Denver Partnership and USGBC is vital to our success.

ANALYTICS Coming soon.

As the Denver 2030 District builds it’s district energy, water and transportation analytics engine we will be able to provide building members with more robust custom reporting. These custom reports, working privately and directly with individual building members, will include comparative analysis of member building performance compared to both district-wide performance and representational peer group performance.

In addition, we are going to leverage the strength of our professional stakeholder members to provide free basic energy and water audits and discounted detailed audits. Our goal is to not only help member buildings understand how their performance compares to the district and its goals but to provide information and tools to improve performance. DISTRICT GOALS

The Denver 2030 District goals call for incremental reduction targets for new and existing buildings set by the 2030 Challenge for Planning, which was issued by architecture 2030, a non-profit organization committed to transforming the built environment.

2030 DISTRICT2030 DISTRICT REDUCTION REDUCTION GOALS GOALS DISTRICT GOALS

The energy baseline for the 2030 District energy goal is the Department of Energy’s Commercial Buildings Energy Consumption Survey (CBECS) 2003 data set, which is the same data set used to baseline ENERGY STAR Buildings. For water and transportation carbon, no national standard exists for benchmarking, so the Denver 2030 District developed custom regional baselines. The water baseline was developed in collaboration with Denver Water using an average of 2010 and 2011 water data, which were years with typical weather and precipitation. The transportation baseline was developed in collaboration with the Downtown Denver Partnership using the data from their 2013 commuter survey to baseline future transportation carbon reductions.

2030 Water – Benchmarks and Baselines by Austin Krcmarik, Denver Water The Denver 2030 District goals set a minimum reduction of 10% by 2015 and a goal of 50% reduction by 2030. These reduction goals are great, but Denver Water has been moving from reductions to efficiency metrics. Denver Water would like to see that all customers first get to an efficient baseline for their industry type and then work on further reductions from there. Unfortunately, there are not many national or local Water Use Intensity studies that give good insight to what benchmarks should be for major building types within the Denver 2030 District. Through a partnership between the Denver 2030 District data committee and Denver Water we were able to aggregate water consumption data by primary building type to create relevant district benchmarks. Water use intensity in the Denver Metro Area has been falling for all customer types, so benchmarking is a difficult task because we need to balance recent trends while realizing that benchmarks will probably continue to fall as fixtures are updated and technology gets better.

The Alliance Center at 1536 Wynkoop Street is a multi-tenant office building owned and operated by the Alliance for Sustainable Colorado. The Alliance for Sustainable Colorado is a nonprofit organization whose mission is to support environmental stewardship, economic stability, and social equity in Colorado.

The Alliance Center was renovated in June of 2014 as part of the U.S. Department of Energy’s Commercial Buildings Partnership program. The renovation sought to further improve the performance of already energy efficient historic building, while revamping the interiors to focus on occupant comfort and productivity. The new collaborative workplace serves as a sustainability hub for the community and attracts environmentally focused tenant-partners. The collaborative hub model using a combination of shared and tenant-dedicated space allowed the occupancy of the Alliance Center to more than double (from 120 workstations to 260).

A 5-year simple pay back was the economic goal for the energy efficiency measures. Energy efficiency measures included improvements to the envelope, lighting, and HVAC. A small amount of energy savings was also attributed to the project’s Energy Efficiency Measures water use reduction and related reduction in • Improved roof insulation (R-10 to R-32) hot water demand. Plug load management and engagement of occupants was a central part of • Cool roof the project. The Alliance Center even included • Energy efficient LED interior lighting fixtures environmental performance regulations in its space with occupancy sensors usage agreement for tenants. • Reduced exterior lighting load (2kW to 1.25 kW) • Reduced equipment power density (1.0 to 0.8 w/SF) • Plug load management • Low-flow plumbing fixtures • DX cooling with good part-load efficiency, supply air temp reset, and dual temp economizer • New VAV boxes and demand controlled ventilation CASE STUDY The Alliance Center

The results of the work are almost too drastic to believe. The building’s ENERGY STAR score increased from 52 to 89. And the site energy use intensity (EUI) dropped from 162 kBtu/SF to 61.7 kBtu/SF - a 62% improvement. Most importantly, energy expenses decreased 22% from $1.57/SF to $1.23/SF.

Prior to the project, 1660 Lincoln had no building automation system, used steam induction chillers, non-condensing boilers, as well as incandescent, halogen and T12 lighting. The building has since replaced the inefficient lighting with LEDs, installed high-efficiency condensing boilers, implemented a Carrier iVue building automation system, and is cooling using heat recovery chillers. Energy retrofits of this scale rarely happen and when they do it’s generally in a vacant building. At 1660 Lincoln, this project began with 60% occupancy and was completed at 80% occupancy. The increase in occupancy actually masks some of the efficiency improvements, but also speaks to the project team’s impressive ability to perform a large-scale energy project in a competitive downtown market while preserving tenant comfort and health - a hallmark of green building!
