    Memorial Day Safety According to the Wall Street Journal, Memorial Day is the second most dangerous  holiday of the year, with Independence Day being the deadliest.  This Memorial Day, keep yourself and your family safe.

    – Buckle up when on the road. – Make sure there is a designated driver. – Obey speed limits and traffic laws. – Make sure tires are properly inflated. – Use caution.

    • There are 13.1% more traffic deaths, on average, that weekend than a typical non‐ holiday weekend.

    • Memorial Day has 32% more fatalities than the preceding three days, (according  to a study on holiday fatalities by Arnold and Cerrelli). The reason is likely the  increased travel during that day.

    • The 13 percent of drivers and passengers in cars and light trucks who do not wear  belts accounted for 44.7 percent of fatalities in 2014.

    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.

    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.

    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 second webinar  of a three‐part series will focus on Technologies and  Strategies in Deep Energy Retrofits. The webinar will  address the common elements of nearly all deep  energy retrofits, how to choose an approach to match  the strengths and weaknesses of the building and  common deep energy retrofit technologies and  strategies.

    Learning Objectives

    1. Understand the relationship between deep energy retrofits and code requirements

    2.  Understand opportunities to use deep energy retrofits to make non‐energy improvements 

    to buildings

    3.  Be able to align deep retrofit strategies with building strengths & weaknesses

    4.  Be able to identify pitfalls to pursuing deep energy retrofit technologies and strategies

    At the end of the this course, participants will be able to:
