SEMINAR 22: Feedback: The Essential Ingredient for High Performance Green Homes
Chair: Audrey Dupuis, Pageau Morel, Montreal, QC, Canada
In high performance homes, comfort drives design, design drives energy use and careful design choices drive actual energy performance and occupant satisfaction. However, thermal comfort standards don’t include energy efficiency compliance requirements, leading to mismatches between comfort and energy efficient designs. This seminar explains why and how to use the vocabulary of thermal comfort as the first solution in solving residential energy problems. It also describes how feedback tools can be useful in calibrating modeling inputs to verify and ensure that actual performance outcome are achieved by design. The cost of poor design choices is also discussed.

Forum 1 (Intermediate) Expanding Our Perceptions of Building Performance: Updating Standard 105
Chair: J. Patrick Carpenter, P.E., Facility Performance Engineers, Cinnaminson, NJ
Standard 105 which provides a method of building energy performance determination, expression and comparison was last revised in 2014. The expanding use of energy benchmarking in many parts of the country reflects the increasing awareness of the impacts of building performance on the environment. There is also growing concern about the impact of buildings on water consumption. Guidance with evaluating these impacts is important to many designs as well as potential legislation. Feedback from the industry on the current standard will help TC 7.6 begin the process of reviewing, updating or expanding this standard.

Seminar 46 (Intermediate) Comparing the Energy, Emissions and Economic Impacts of Buildings in Energy Performance Calculations
Committee Chair: Larry Brand, Gas Technology Institute, Davis, CA
• Describe how the energy, emissions and economics impact calculation framework can be used in energy performance comparisons
• Explain how the EEE framework complements the ASHRAE Standard 90.1 and 189.1 performance calculation methods
• Understand how to apply the relative valuation of metrics in determining energy performance compared to a baseline
• Apply the EEE Impact methodology to a residential building energy performance comparison Measuring and comparing technology and building energy performance equitably with minimum unintended consequences has been challenging for decades. One reason is the use of a single metric such as energy cost to determine and compare performance of different options. With increased focus on environmental impacts, the energy cost metric may be incomplete or misleading.
This seminar describes a new way to evaluate performance based on relative valuation of metrics related to energy use, greenhouse gas emissions and cost (EEE) impacts. Application and benefits of the EEE impacts approach in ASHRAE standards and other initiatives are discussed.
Seminar 48 (Advanced) New ASHRAE Hot Climate Design Guide
Chair: Frank Mills, CEng, Frank Mills Consulting, Leyland, United Kingdom

• Describe the energy usage patterns of buildings in hot climates and possible strategies for net zero
• Develop proposals for external cooling of areas around buildings in hot climates
This seminar provides information on the scope and content of the new guide and invites ASHRAE members and others to comment and contribute new ideas. This guide is proposing new low carbon design solutions and also ways to integrate traditional 'passive solar' concepts into modern buildings. The seminar covers building design and also external cooling of areas around buildings and semi external spaces such a Atriums, where members of the public may want to gather, meet sit, eat, drink, relax and in some cases even work. Hybrid and passive designs are explored to consider applications

Seminar 59 (Intermediate) Beneficial Carbon Reduction Strategies: Cogeneration, Electrification and Consumer Options
Chair: Kevin Brown, P.E., The Linc Group, Atlanta, GA
• Explain the impacts that existing building energy policies have on the tradeoffs between incumbent fuel sources, new distributed energy resources and energy efficiency
• Understand how building energy policies can evolve to accommodate and encourage the market adoption of zero energy and zero carbon buildings
• Distinguish the role of electrification of previously fossil-fueled end uses from other approaches to carbon emission reduction
• Identify the role of CHP and other affordable options as alternatives to electrification in a balanced carbon emission reduction strategy
High performance building technologies such as combined heat and power, heat pumps, and photovoltaic panels can be an integral part of beneficial greenhouse gas emission reduction strategies. Rapid advancements in each of these areas, along with dynamic changes in the electric grid, are creating opportunities and challenges when trying to determine a balanced approach to achieving the ultimate goal of zero carbon emissions. Diverse viewpoints on technology improvements, polices that may inadvertently or intentionally favor one type of fuel over another and emission reduction options that provide consumer and societal benefits are shared.

Seminar 69: Climate Change Liability for Owners, Designers and Manufacturers
ASHRAE provides guidance on use of climatic data in designs and facility assessments. Currently, the vast majority of design firms use historic climate files. This practice aligns with professional standard of care. However, given the international consensus that climate is changing, use of historic weather data in designs could lead to underperforming systems or building failures. Projected weather files from regional climate models include their own uncertainty and risk. This puts architects, engineers, owners and manufacturers in a difficult situation. This session covers climate change science, risks associated with various weather file use and changing standards of care.
