This powerpoint was presented by Chris Smith, and speaks to Energy 350’s experience with challenges, discoveries, technology solutions since marijuana was legalized in Oregon in 2015.

This paper was presented by Chris Smith, and speaks to Energy 350’s experience with challenges, discoveries, technology solutions since marijuana was legalized in Oregon in 2015.

This powerpoint was presented by Josh Weissert, and speaks to Energy 350’s role in opening up the RTU retrofit market.

This paper outlines details on retrofitting constant volume systems to variable volume systems using Advanced RTU Controls. It explores the following:

• Where these retrofits are happening
• The economics of retrofitting
• Present obstacles to overcome
• Control methods, options and results
• Cost-effectively verifying savings
• Results from hundreds of system retrofits, including: trend data, pre- and post-metered data
• End-user feedback after system retrofit

Key takeaways for the reader will be to:

• Understand that there is now significant and cost-effective energy savings opportunity for packaged RTUs
• Share experiences in approaching a difficult market to engage
• Explore control options, retrofit methods and configurations

This presentation accompanies the Indoor Cannabis Growing paper, and was presented by Mike Christianson at the 2018 ACEEE Summer Study on Efficiency in Buildings.

This paper documents Energy 350’s challenges, learnings, and technology solutions that we’ve discovered since Oregon’s legalization of recreational cannabis in 2015. The intent of this paper is to share knowledge and accelerate the learning process for states recently legalized or facing legalization. This paper will share breakthroughs in the following areas:

• How to remove heat caused by dehumidification from the growing environment, which is typically dominated by the need to cool.
• How to mitigate challenges in balancing indoor environment plant needs, which are CO2 enriched and clean, with traditional efficient HVAC design, which relies upon free or efficient cooling in cool weather without introducing impure air into the growing space and exhausting unacceptable amounts of CO2.
• How to engage a historically unorthodox population of growers with little access to capital and even less time to consider efficiency.

Pay for Performance Case Study: 3 Years of Performance, presented by Chris Smith at the 2018 ACEEE Summer Study.

This paper explores the concept of Pay for Performance programmatically and technically, using 1000 Broadway as an example.

Do Touch That Dial! How Satisfied Were You With That Tier II Power Strip? was presented by Nick O’Neil at the 2018 ACEEE Summer Study.

Building upon a successful direct-install campaign to better understand the energy savings potential of Tier 2 Power Strips, PG&E explored a retail delivery model in 2017. By offering Tier 2 products at a discount to over 1,000 select PG&E customers and following up with a 2-month post-install survey, we were able to answer critical questions needed to assess the cost-effectiveness and feasibility of a future utility program retail delivery model. This paper will explore the Tier 2 promotion and survey methodology and present findings from the post-install survey to help answer several important program specific questions, such as:

• What was the initial installation rate and persistence over time?
• What reasons were given for removing the device over the 2-month post-install period?
• How easy was the installation using the manufacturer provided instructions?
• How satisfied were customers overall with the power strip?
• Is there a relationship between customer demographics and persistence?

Powerpoint of Chris Smith’s presentation on Industrial Retrocommissioning – Stories from the Field

Paper relating to presentation. This paper aims to explore the following:

• Overview of RCx program structures
• Where programs should focus resources to obtain const-effective savings from retrocommissioning
• Success stories and several lessons learned from past projects and different program structures

Powerpoint presentation by Josh Weissert on Engaging Large Industrials: Beyond Capital Projects.

Overview of presentation includes the following topics:

• Foundation of Engagement
• Leveraging Industrial Sites
• Offering O&M and SEM is a Key Tool to Sustained Engagement
• Going Beyond Energy Efficiency

This is the paper accompaniment to the presentation Engaging Large Industrial Customers.

This paper explores the following:

• Using gateway projects to open doors. What are good gateway projects?
• Leveraging motivations to explore and implement energy conservation measures. Beyond the energy economics. What gets plants to commit?
• Tools to deploy while on your first site visit in a plant that is overwhelming.
• How to develop rapport with an industrial. What not to do.
• Using Retrocommissioning approaches to earn trust with data driven presentations and results.

Powerpoint of Nick O’Neil’s presentation on metering:

More Value to Metering Than Ever Before

This presentation covers the following topics:

• Why do programs meter in the first place?
• What is involved with metering and what are common barriers?
• Demonstrating value with examples from the field
• What is the upfront and long-term value to metering?
  Value from 3 perspectives: – End-user – Utility efficiency program – Regional planner
• What to do with all this data?

Paper accompaniment to presentation, More Value to Metering Than Every Before.

By highlighting the many benefits to metering this paper aims to explore the following:

• Perceived value of metering in utility programs from customer and utility perspectives
• Reasons why updated load and savings shapes have been ignored for so long
• Examples from the field of updated shapes and their impacts
