6.Research Subcommittee ReportRolando LegarretaCo Sponsor Research TC9.6 1729 update: load research on radiant systemo Majority of the experiment has been completedo About to start more evaluation on implications to RTS and HBM methodso Follow-up meeting need to be scheduled to continue discussiono Experimentation show that peak load for radiant system are higher systematically thanair system, also total heat gain for radiant system is also largero Simulation shows larger increase in load than experimento Steve Bruning mentioned several things to consider: 1. mass-coupled radiant system,hydronic load is different than space load; 2. Ventilation air change rate in radiant spacemaybe lower than used in the experiments. Convection heat transfer rate maybe lowerin radiant system because of lower ACH required RTAR by TC 4.7 on ground heat conduction heat transfer (looking for co-sponsor)o Not sure of the status at TC4.7o Residential load calculation chapter has the most updated data RTAT 1847 updateSee Appendix III for sub-committee meeting minutes7.Programs Subcommittee ReportGlenn Friedman Rachel gave an update:o Workshop on missing linko Seminar on Research project 1792 Future program ideas:o Deadline to submit next meetingo Follow-up workshop on missing link, focusing on YEA.

URGENT Request – Some TC members recently began to improperly useASHRAE Letterhead to submit Comments on Standards and Codes in PublicReview, which implies to the code authority or standard writing organization thatit is an official comment of ASHRAEFor Standards and Codes there is a clear process. It comes through with a vote by theTC to the Manager of Standards (MOS) and then the ASHRAE President has to approveit before it is submitted. If denied, each TC member can still submit their comments asindividuals, but not on ASHRAE letterhead.4. 18-19 Rosters Access & Distribution - Remember, the current 2017-2018 roster foryour TC, TG or MTG is in effect until after the June meeting this year – throughSaturday, June 30th.By now, each TC, TG and MTG chair should have received a PDF & MS-Excel file oftheir new 2018-2019 roster from their Section Head or staff for distribution to thecommittee. In addition, each member can view all of the rosters of their committees onthe ASHRAE Website. Go to and log-in (if youhave not logged in lately, you might need to set up a new username and password),click on the "Membership” tab in the header, Go to the “My ASHRAE” section of theMembership page and click on "My Participation" text, and scroll down to the “Manage”link. Click on the "Committees” link in the left sidebar. Now, you should see all of thecommittees that you are a member of will appear. Click on the "blue" roster text on theright hand side of a committee name to reveal the roster in various file formatsThe Provisional Corresponding Member (PCM) position is a relatively new position onTC/TG/TRG rosters. This position allows potential new members to be added by staff tothe committee roster any time a request for membership is made by an individual. Theposition has a 2-year term on the committee. Staff will notify the chair and reissue a newroster to the committee chair any time a provisional member is added. The TC/TG/TRGchair has the option each year during the regular roster update process to convertprovisional CMs that have been active participants on the committee the past year intoregular CMs or voting members or drop them. If no action is taken, they will time expirefrom the roster and be removed by staff.Page 3 of 19

Announcements and Reminders for TC/TG/TRG & MTG Chairs Houston 20185. MTG.EBO (Effective Building Operations)Scope: MTG.EBO will coordinate the activities of multiple TC/TG/TRG and otherstakeholders in the area of training and tools to support the operation of buildings toenhance the indoor environment and use energy effectively. Responsibility will includesuggestions for research as well as development of technical programs and specialpublications on effective building operation for energy management.The initial MTG roster includes Voting Representatives and Alternates for TCs 1.4(Control Theory and Application), 7.3 (Operation and Maintenance Management) 7.8(Owning and Operating Costs) and GPC 1.3 (Building Operation and MaintenanceTraining for the HVAC&R Commissioning Process)Other TCs GPCs, and SPCs may also now wish to participate in this MTG with a VotingRepresentative and Alternate(s) given its scope and charge.6. Let’s Celebrate ASHRAE’s Technical Excellence Historically!ASHRAE is highly regarded for its technological advances. Consider that theseadvances evolved from the efforts of our predecessors and you, and the currentmembers of ASHRAE’s Technical Committees in advancing HVAC&R technology arebuilding on a deep foundation. So, what is the historical foundation of your TechnicalCommittee specialty? ASHRAE will be celebrating its 125th anniversary in a coupleyears. The Historical Committee has a project to publish articles in the ASHRAE Journaland organize paper presentations celebrating our technical heritage for the anniversary.We plan to emphasize technical advances after 1920. Can you help with an article or apaper or can your TC organize and sponsor a program session for the 2019-2020meetings?Here is a list of topics that TC members have already suggested. Development of open communication protocols such as BACNET.Modern improvements in psychrometrics (Goff & Gratch).History and effect of the Environmental movement on our technology. Howtechnology and equipment has improved the indoor environment.The refrigerant revolutionSolving the problems of “sick buildings.”The re-discovery of past technology and its application today (such as districtenergy, hydrocarbon refrigerants, off peak energy storage, “total energy”systems, etc.)History of the application of electronics to HVAC&R technology.ASHRAE’s long history in applying innovative technology.History and importance of frozen food technology.All of these topics and others you may think of need to be written up and/or presented bysomeone.How about YOU?Page 4 of 19

Announcements and Reminders for TC/TG/TRG & MTG Chairs Houston 2018If you can’t write a paper, the Historical Committee is also interested in suggestions forthe best ASHRAE technical papers since 1995.The 125th anniversary will be celebrated at the 2019 Annual meeting and the 2020winter and Annual meetings. The Historical Committee has been charged with theresponsibility of organizing Society and industry history projects for the 125th. If youwould like to submit an article or a paper organize a program session, or suggest thebest technical paper(s) since 1995, contact Chris Preyor, is a deadline – please submit abstracts or outlines before December 7, 2018 forconsideration for the Orlando 2020 or Austin 2020 meetings.7. Oversight of TC websites with regard to Technical Bulletins (White Papers) andalignment with Society positions, policy, or opinionsTCs are allowed to develop Technical Bulletins - A Technical Bulletin does not resultfrom a technical meeting and is a brief 1-2 page statement on a special interestHVAC&R topic that has been developed by either a technical or grassroots committee ofASHRAE. After the TC approves the Technical Bulletin, TAC is responsible forcoordinating a peer review by a minimum of three persons with expertise in the field ofthe bulletin before it can be posted. In addition, ASHRAE’s policy for websites states thefollowing: “4 (3) f. Statements and presentations may not appear on web sites thatstate, purport, or imply that they present ASHRAE positions, policy, or opinions.”8.

This report describes the vision held by members of the American Society of Heating, Refrigerating and Air-Conditioning Engineers. This vision is of a future when buildings will produce as much energy as they use. These are net zero energy buildings (NZEBs). We believe such buildings can be market-viable by the year 2030.

District heating often involves a heating substation installed in the basement of a building. It receives the heating carrier from a heat generating station and via a heat exchanger makes it available for the building heating system. An individual heating system in many cases consists of a boiler heating water up to required temperature for

HFC refrigerant. The units are factory tested in both heating and cooling modes. These units meet the DOE-2018 (Department of Energy), ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1-2016, and IECC-2015* (International Energy Conservation Code) minimum ef ficiency requirements.
