What You Missed
4 Capital Communiqué November 2019
Ryan started off by talking aboutheat transfer fundamentals and howit relates to hydronic systems. Allmatter has internal energygenerated by the movement ofmolecules. The amount of internalenergy can be labelled as theobject’s heat. We measure this bythe temperature of the object. Allsystems try to reach a thermalequilibrium by equalizing thetemperature of the components withthe surroundings. Heat transfer istherefore dependent on the changein temperature. There are threeforms of heat transfer, conduction,radiation and convection.
• Conduction is only throughsolids and is dependent on thetemperature difference, materialproperty (conductivity), area, andthickness in the direction of heattransfer. • Radiation is heat thattravels at the speed of light, travelsby line of sight and can be reflected.It is dependent on the temperaturedifference, area, and materialproperty (emissivity).• Convection is the third typeof heat transfer, and deals with themotion of a liquid or gas, naturalconvection or forced convection.Natural convection involvesbuoyancy, while forced convectioninvolves motion created by a pumpor fan. Convection is dependent onthe temperature difference, area,and fluid properties (density,velocity, specific heat).
Most heat transfer involves all threemodes, conduction, convection andradiation. Energy is conservedbetween systems according to theFirst Law of Thermodynamics.The change in internal energy can bemeasured by the enthalpy of theobject. 1BTU/HR is the amount ofenergy required to heat 1lb of water1 degree Fahrenheit.
Hydronic heat transfer can becalculated by Q = 500 x GPM xdelta T. This equation only applies
for water at 20 degrees. Density andspecific heat change as the fluid andtemperatures change. For air, thedensity and specific heat is a lot less,so the heat transfer is a lot less.Sensible heat transfer can becalculated as Q = 1.08 x CFM xdelta T. A lot of systems aredesigned around a temperaturechange of 20 degrees Fahrenheit.
There is a limit to the change intemperature that can be reached byincreasing the flow. As the flow rateincreases, the temperature does notchange proportionally. There is alimit to how much heat transfer isavailable for a system. As the flowrate is increased, noise and pressuredrop become a concern. Typicalmaximum flows for noise is 4ft/sec,and for pressure drop is 4ft/100ft.
Ryan asked why choose a hydronicsystem? Water is a very good heattransfer medium. It has muchgreater heat transfer capability thanair, it is easier to install smaller pipesin a system than larger ducts to getthe same heat transfer, water is safeto use and is readily available, andit’s easy to make piping changes tothe system for zoning.
Typical heating supply temperaturesare 210F, 180F, 160F, and 110F;typical chilled water temperaturesare 45F, 60F, maybe even 25F.Domestic hot water productionneeds over 160F.
Originally, 210F was based on woodfired boilers with no temperaturecontrol. With the transition tonatural gas, controlling the burningprocess allowed the watertemperature to be controlled to180F. More recently, there’s been ashift away from high temperatureboilers to low temperature boilers,which offer better control andefficiency when the return water isbelow 130-134F. The 130-134Fthreshold is when condensationbegins to occur in the flue gasesdepending on the amount ofoxygen in the burner. Condensing
boilers provide the system withextra efficiency. This can beachieved with a supply temperatureof 160F and a 30F temperature drop.
Europe has been designing around a20C (36F) temperature drop forsome time. The higher temperaturedrop allows for lower flow rates,smaller pipe sizes, and smallerpump requirements. Just as there isan upper limit to flow rates, there isa limit to the minimum flow that ispractical. Too slow of a flow and itmay no longer be in turbulent flow,so the heat transfer will change.
Older hydronic systems can beupgraded to make use of newertechnologies and lowertemperatures. Heat loss calculationsshould be confirmed to determinewhether a lower average watertemperature would achieve theoutput capacities required with theexisting terminal units. Additionalterminal units, such as more wall finpiping, may be needed to meet theload with the lower temperatures, orthe terminal units may need to bereplaced with higher output units,such as fan coils.
Ryan concluded his presentation bydiscussing heat exchangerfundamentals. Heat exchangerstransfer heat between mediums.Examples include a boiler whichtransfers heat from gas to water, ora steam to water heat exchanger.
The three main types of heatexchangers are:• Shell and tube: straighttube, u-tube, horizontal, vertical.• Coiled: typically used fordomestic hot water production usingboiler water flowing through a coiland domestic water in the maintank.• Flat plate: plate and frame,brazed plate.
Heat exchangers can either operatein Parallel flow or counter flow;however, most heat exchangers aredesigned for counter flow because of
5Capital Communiqué November 2019
the better heat transferperformance. Heat exchangerperformance is dependent on theheat transfer coefficient, area, andlog mean temperature difference.Fouling inside the heat exchanger
occurs over time and will reduce theheat transfer capabilities.
President Aaron Dobson thankedRyan MacGillivray and remindedattendees of the survey which will be
emailed. The next meeting isscheduled for November 19th at theCenturion Conference and EventCenter.

News UpdateASHRAE Recognizes 2019LowDown Showdown ModelingChallenge Teams
ATLANTA (Oct. 9, 2019) – ASHRAErecognized the 2019 LowDownShowdown modeling competitionteams. The competition was held inconjunction with the 2019 ASHRAEBuilding Performance AnalysisConference, Sept. 27-29 inDenver, Colo.
The ASHRAE LowDownShowdown engages architects,engineers, designers and energymodelers by working on integratedteams in the creation of effective
workflow and outstanding design inreal-word building efficiencychallenges.
“The competition not only challengedteams to achieve near net-zero, butalso to include design and modelingelements to create a resilientbuilding capable of withstandingnatural disasters and providingprolonged emergency operations,”said Annie Marston, competitionchair.
This year’s model building was a90,000 square foot city hall (newconstruction) located in San Diego,Calif. The project involved designing
a facility that is meant to be amulti-functional building, housingmany of the cities vital publicservices including being anEmergency Operations Center intimes of disaster or crisis.

Teams were evaluated in sixcategories:
Energy useTeamworkInnovative approachCreativityWorkflowPresentation
First place and fan favorite wereawarded to C.R.E.A.M. (CarbonRules Everything Around Me) for aproposed city hall that can maintainoperations for 14 days during a utilityoutage to coordinate emergencyresponses while maintaining criticalfunctions like prisoner life safetyand security. During an event, thebuilding will transition to a setbackmode, minimizing energyconsumption by relaxing thermalcomfort targets. Building systems willthen draw energy from a 10,000 kWhbattery system & 427 KW PV arrayfor power and 10 kgal potable & 20kgal non-potable water storagetanks.
“We saw the Lowdown Showdownas an opportunity for our team tocollaborate across Built Ecologyoffices coast to coast and toexperiment using new tools andworkflows,” said Jason Lackie, teamcaptain for C.R.E.A.M. “With thewide-ranging scope of this year’scompetition - encompassing aspectsof energy, water, resiliency, andhealth and wellness - everyonehad a chance to step up andshowcase their expertise while alsobeing challenged to integrate thatwork with an evolving design. Asmuch as the pallet of tools we drewon helped with this multifaceted
design problem, our team’s successdepended on our ability tocollaborate through obstacles.”
Other teams presenting their resultsare as follows:
Highway to Sustainability – Thissecond place team designed a newcity hall with a 3-story atrium toprovide ample space for greenwalls, skylight and naturalbreeze. The project included aspacious semi-outdoor area forfitness activities and the deploymentof EnergyBox, an in-house webplatform which speeds up designexploration by automating processesand encouraging collaboration byeffective visualization.
Operation ReSHED – The team’sproject included elevated walkwaysto surrounding critical governmentbuildings for quick access to theEmergency Operations Centerresiding inside the new city hall. Thevertically massed city hall would bedesigned not only to transform theskyline, but creates opportunities forresiliency against forecasteddisasters, increasing energyefficiency during the regularoperation and to provide a safe andhealthy environment for theoccupants.
Parametric Posse – The teamincorporated parametric modelingto replace design assumptions madewith data-driven simulations toachieve a holistic design thatexceeds technical requirements,leverages passive strategies, andsupports use during emergencysituations. Using both proprietary
and open-source software for theparametric modeling, the base digitalmodel allowed for interface withenergy, daylighting, and climateanalysis tools.
Ulti-Performance - The team’sproject included assembling anintegrated team using a variety ofdesign tools to achieve a netpositive building designed forcomfort, using dynamic glazing,natural ventilation, and a greenroof outdoor amenity.
Resilience features includedunderground water cistern, PV andbattery storage.
