ASHRAE has just released the next Advanced Energy Design Guide. This zero energy guide focuses on what is needed to achieve zero energy in office buildings. The session will focus on the EUI targets focusing on the selection and design of the HVAC systems. It will also cover lighting, plug loads, and envelope design as it applies to the HVAC system to ensure that the office building can be built to the zero energy target. How-to tips and practical advice will be presented as well as successful zero energy case studies.
1: Overview of the AEDG Series and a Look Towards the Future
Tom Phoenix, P.E., CPL (Clark Patterson Lee), Greensboro, NC, USA
This presentation will provide historical context to the Advanced Energy Design Guide Series (AEDG) and provide context for the series of Zero Energy Guides. The presentation will also discuss what is next as well as the overall goals and objectives of the AEDG Series.
2: The Process of Creating the Zero Energy Office Guide
Paul Torcellini, Ph.D., P.E., National Renewable Energy Laboratory, Golden, CO, USA
The AEDGs are created by a project committee of volunteers from USGBC, AIA, ASHRAE, and IES. This committee is responsible for creating the content based on simulation results, case studies, and professional experiences. As part of the overview, this presentation will examine loads that influence the HVAC selection including lighting and plug loads. Overall energy targets will be presented for office buildings to achieve zero energy for all climate zones.
3: Marriage of the Envelope and HVAC Selection and Design
Daniel Nall, P.E., Daniel Nall, Consultant, LLC, Princeton, NJ, USA
The architecture of the building is a critical piece of creating a zero energy office building. This presentation will highlight critical decision points where the architect and engineer, working together can create envelopes that will lead the way to HVAC system selection and design to minimize energy. The selection of equipment configurations will be discussed showing the benefits of certain system configurations as well as strategies to minimize the HVAC loads through this optimization of envelope and system selection.
4: A Deep Dive into HVAC Systems for Zero Energy Buildings
Ronnie Moffitt, P.E., Trane, Inc., Lexington, KY, USA
The final presentation in this seminar will focus on specific strategies and how-to tips for designing and specifying the HVAC system. Practical strategies will be presented related to sizing, system configuration, and thermal energy storage will be included It will include operations guidance on how to operate a zero energy building and maintain its energy savings long-term. Finally, metrics for evaluating the success of the design will be presented such that confidence can be gained that the building will achieve its zero energy goals.Wednesday, June 26

As the built environment is moving towards decarbonisation, the electric grid will require new design and operation considerations to integrate increasingly high levels of renewable energy. The grid also incorporates intelligent buildings capable of managing their own loads and storage capacity to 1) reduce their energy use and peak power demand, and 2) support grid flexibility and grid services that will have increasing value to grid operators. The objective of this seminar is discussing the technical challenges and available solutions regarding energy systems integration, distribution intelligence, the role of buildings, and steps required to operate in a smart-grid environment.
1: Smart Grid-Ready Buildings: Enabling Tools and Solutions
Glenn Remington, Consumers Energy, Jackson, MI, USA
This presentation will focus on the available tools and solutions that could enable buildings to manage their own loads and storage capacity while reduce their energy use and peak power demand, and support grid flexibility and grid services.
2. Smart Grid Distribution Intelligence: Towards a Resilient, “Self-Healing” Grid
Andy Haun, Schneider Electric, Andover, MA, USA
This presentation will discuss available solutions on outage detection, response and “self-healing” capabilities in order to meet building needs during interruptions of grid services. The presentation will also examine potential applications of distribution intelligence with the ability to optimize the balance between real and reactive power.
3: Integration of Renewable Energy Systems: Opportunities and Challenges
Aaron Bloom, Energy Systems Integration Group, St. Paul, MN, USA
This presentation will discuss opportunities and challenges for dynamics, control, and automation of renewable energy systems integrated into a smart grid environment to meet buildings' energy and peak power demand needs.

Cooling towers can be the largest water consumers in commercial buildings, but they also represent one of the best sources for water conservation. Proper cooling tower water management is the key, but it is often treated as an art with mixtures of unknown chemicals and significant blowdown (i.e. wasted) water. There are several alternative water treatment systems available today, but which work, and which are not worth the effort? This session will review cooling tower impacts, several of these technologies, and provide results of recent technology field tests showing promising results.
1. Current Challenges with Cooling Towers
Rafi Karim, P.E., Affiliated Engineers, Inc., Pasadena, CA, USA
Evaporative cooling systems use a significant amounts of water by design. One of the main challenges with maintaining optimal system efficiency in cooling towers is effective water treatment. This session will illustrate the fundamentals of evaporative cooling system and discuss the significance of water chemistry. Audience will get the bird's-eye view of the pressing challenges (water consumption) and opportunities (water conservation) associated with cooling towers in the U.S.
2. Alternative Water Treatment Systems
Jesse Dean, National Renewable Energy Laboratory, Golden, CO, USA
What? Another alternative water treatment system? This presentation will cover the comprehensive validation of two systems in six buildings with the pros and cons of each one. Detailed monitoring and analysis show the impacts on water consumption and maintenance.
3. Chemical Free Water Treatment
Michael Deru, Ph.D., NREL, Golden, CO, USA
No chemicals? How do they do that? This presentation will include a review of two chemical free water treatment technologies for cooling towers. Results from testing these technologies in three buildings in three different climates will be presented. The water and maintenance savings are impressive. Come to learn how it works and if it can work for your project.
