An in-depth look at ASHRAEs work in the residential market as well as guidance on several aspects of residential design is offered in four free seminars at the 2017 AHR Expo.The 2017 ASHRAE Winter Conference takes place Jan. 28-Feb. 1 at Caesars Palace with the co-sponsored AHR Expo being held Jan. 30-Feb. 1 at the Las Vegas Convention Center. To register for the Conference, which includes free access to the Expo, visit www.ashrae.org/lasvegas.
The four seminars are free, and no badge is required to attend. They take place Tuesday, Jan. 31, from 11 a.m. until 5 p.m.
Leon Shapiro, Conference chair, said the sessions are being held at the Expo given the large number of exhibitors with a residential focus as well as the many residential contractors who will be attendees. Statistics from the 2016 Expo show that 43 percent of visitors indicated they work in the residential sector.
The sessions highlight the growing importance within ASHRAE of residential energy use and the steps ASHRAE has taken to partner with both the public and private sectors to improve residential design and energy standards, he said. They also serve to increase public awareness in residential energy efficiency.
He notes that design and installation have a tremendous impact on residential HVAC capacity and efficiency, so one of the seminar highlights the consequences when residential design and installation standards are not adhered to. Another session provides best practices for distributing heat in residential HVAC air and hydronic systems, while another offers real world experience on how actual energy use and thermal comfort can differ from the homeowners expectations.
The seminars are:
Did It Really Work? Theory vs. Practice in Residential HVAC. The late, great Yogi Berra once said: In theory, there’s no difference between theory and practice. But in practice… there is. The speakers at this seminar agree with Yogi. Using measured data from both dry and humid climates, they show how actual energy and thermal comfort in real-world houses differs from expectations. But beyond the problems, the speakers also show data from specific designs and installation practices that have helped contractors meet and exceed customer expectations with simple, low-cost, reliable equipment instead of whiz-bang, expensive stuff that too often fails to deliver comfort and low energy performance.
ASHRAE’s Residential Initiative: Why We Care. Although ASHRAE historically has not focused on residential HVAC energy use, the residential sector consumes at least as much energy as the commercial sector, and approximately one-fifth of all primary energy in the United States. Three Presidential Fellows will present on ASHRAE’s recent endeavors into the residential sector. The session covers how the Residential Ad Hoc Committee became the newly established Residential Building Committee (RBC), what purpose the RBC serves, the importance of residential design in ASHRAE standards and a summary of ASHRAEs residential market advocacy efforts with government agencies.
International Experience and Contractors Perspectives on Residential Aspects that Need to be Considered on Every Job. It has long been recognized that design and installation faults have an impact on HVAC system capacity and efficiency. However, the magnitude and consequences of these fault impacts was unknown. This seminar provides insights from a recently concluded four-year investigation that quantifies the consequences of failing to observe the design and installation elements contained within the industrys HVAC Quality Installation Specifications. It also highlights steps taken in Europe that are relevant to the North American market to reduce residential energy consumption, including deep retrofit strategies and incremental options with large market uptake for overall large impact.
Flex Ducts, Hard Ducts and No Ducts: Migration Patterns for Duct Hunters (or not) in the Land of Thermal Comfort. In the land of comfort, educated homeowners are changing their thermal expectations from HVAC systems, and contractors are on the front line hunting for the best solutions. Regardless of ducts or pipes, the migration of heat takes a basic understanding of what works and what doesnt. It is not easy to figure out the right design for the application, especially as homes get more efficient. Low-cost ducted systems may not always work right or be the best fit. This seminar looks at best practices for distributing heat in residential air and hydronic systems, including ducted and radiant design options.
ASHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment. The Society and its more than 56,000 members worldwide focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability. Through research, standards writing, publishing, certification and continuing education, ASHRAE shapes tomorrows built environment today. More information can be found at www.ashrae.org/news.
