LearningObjectives

1. Discuss the paramount role of integrative

process and early goal‐setting in achieving

aggressive building and district‐scale energy

performance goals.

2. Illustrate how a proactive design strategy can

ensure that a building designed today can support

a district zero‐energy vision.

3. Describe how a project team can address

diverse and sometimes conflicting occupant‐,

building‐, district‐, and community‐scale needs in

the design and operations of a high‐performance

building.

4. Explain strategies to effectively communicate

the value of high‐performance buildings to

occupants, the community, and the industry at

large.

yThis Design Development Energy Report (DDER) is a tool to assist the design team in making decisions to improve the energy performance of the Utility Administration Building design. As a participant in Fort Collins Utilities Integrated Design Assistance Program (IDAP), a goal of the project is to achieve a Target EUI (Energy Use Intensity) of 32.9 kBtu/SF/year, a 60% energy reduction below the regional median EUI of 82.3 for office buildings. At least 40% of this reduction must come from efficiency and the remaining 20% reduction can come from renewables. This goal aligns the project design with the Architecture 2030 Challenge. In addition, the project team has set a stretch goal of achieving an Energy Use Intensity of 20 kBtu/SF/year. The project team intends to achieve a rating of 100 through EPA’s ENERGY STAR program and to certify the building. In accordance with a goal of attaining a Platinum rating through LEED for New Construction version 4, the project is targeting a minimum of 15 points for Optimize Energy Efficiency and 3 points for Renewable Energy Production.
