3 Safety Moment: Spring is Here! Don t gamble with your safety if you re a professional excavator or homeowner, smart digging always requires a call to 811. Call before you dig! Code Triggering NGRID Programs 3

4 Owner Benefit of Deep Retrofit Owner will get the full benefit of savings from existing conditions NGRID will offer incentives from base code, IECC 2012 Owner will get benefit of improvements over code Reduced ROI for upgrades redefining what s possible in the built environment 4

5 Vision + Mission We believe in a built environment that makes a positive contribution to a sustainable society through dramatic improvements in energy performance. NBI takes leading edge practices and technology applications for high performance buildings and translates them into innovative and practical solutions for the energy efficiency and commercial building industries. East Boston Public Library East Boston, MA virtuous cycle We are an engine of innovation for the energy efficiency industry. We drive research, uncover solutions, and advance industry practices and policies that deliver positive change in the built environment. 5

7 Course Description A Deep Energy Retrofit is a retrofit project that achieves at least 30% energy savings in a building. Success with this kind of project requires more than widget based retrofits with a focus on one item upgrades to buildings. This first webinar of a threepart series will focus on Vision, and Process in Deep Energy Retrofits. The webinar will address how the design approach to these projects must differ from high performance new construction projects, how to identify good candidates for deep energy retrofits and the tools and resources available. Learning Objectives At the end of the this course, participants will be able to: 1. Understand the meaning of a Deep Energy Retrofit 2. Understand how to identify opportunities for deep energy retrofits both within a particular project and in groups of buildings 3. Understand the steps required to assess building conditions in order to support a Deep Energy Retrofit 4. Understand how to assess different Deep Energy Retrofit Strategies for a project 7
