<div>Nuno,</div>
<div> </div>
<div>I have used the IndoorPoolCalc.xls spreadsheet tool for analyzing indoor pool heating and dehumidification energy.</div>
<div> </div>
<div>It is available here:</div>
<div><a href="http://www.energyideas.org/documents/spreadsheets/IndoorPoolCalc.xls">http://www.energyideas.org/documents/spreadsheets/IndoorPoolCalc.xls</a></div>
<div> </div>
<div>It can be used to find energy savings resulting from using a pool cover, changing air/water temperature and humidity setpoints, new boiler, new dehumidifier and so on. It is based on the Shah Method--see "Calculating Evaporation from Indoor Water Pools", HPAC Engineering, March 2004.</div>
<div> </div>
<div>I hope this helps,</div>

Content-Type: text/plain; charset="us-ascii"<br><br>Hello All,<br><br><br><br>I am trying to compare the difference in glare given off a building<br>after a cladding retrofit (from the perspective of occupants in<br>
neighboring buildings). The original curtain wall cladding is a<br>white/grey marble and glass spandrel panels with a white patterned frit<br>are proposed for the retrofit. I am using Radiance in IES' Virtual<br>Environment program; this is my first time using the simulation<br>
software.<br><br><br><br>I have some questions about determining/selecting material properties,<br>specifically deciding what material type (plastic/metal) and secularity<br>to use for the two cladding options.<br><br><br>
<br>Specifically how do I choose a realistic secularity value for the<br>material I am using? Is there a definitive way to select a value or is<br>it dependant on multiple iterations comparing how the images produced<br>look? I'm trying to use the program to show me how much glare I could<br>
expect to see, if the results are based on constantly tweaking the<br>parameters so the image "looks" right for me I don't see how the results<br>can be accurate.<br><br><br><br>Is a more extensive database of materials and their properties (beyond<br>
what is provided with the program) available? For the materials<br>described below what specularity values would you recommend - and what<br>is the basis behind choosing those values?<br><br><br><br><br><br>My assumptions:<br>
<br><br><br>Marble - Originally white, but panels have become grey with dirt over<br>time, not polished, dull finish<br><br>Type: Plastic<br><br>Colour: (0.91, 0.91, 0.83)<br><br>Specularity: ?????? (I think this may be low because it is not<br>
polished marble)<br><br>Roughness: 0.05 (???)<br><br><br><br><br><br><br><br>Glass Frit - Composed of: Clear glass, 60% coverage white frit, clear<br>glass, 100% coverage white frit. From Window 6, I estimate the solar<br>
reflectance of the system to be around 25-35%.<br><br><br><br>Typle: Metal ??? (Does the frit have specular and diffuse<br>reflection of light?)<br><br>Colour: (1.0,1.0, 1.0)<br><br>Specularity: ????? (Clean polished glass)<br>
<br>Roughness: 0.00<br><br><br><br><br><br>If anyone has information from doing a similar simulation or has any<br>suggestion on what specularity values I should use to model these<br>materials it would be very much appreciated.<br>

Content-Type: text/plain; charset="iso-8859-1"<br><br>Hi Nuno,<br>I have not used Energyplus before. But I guess you would have to do a hand calculation to determine the evaporation rate and model it as a latent load. You could input that latent load as a plug load or even add to people latent load. I know that there is some ASHRAE journal/article which talks about how to calculate the evaporation rate in swimming pools. But unfortunately, I am not able to point you were to download that article. I am sure you can find it if you do some Google search. Hope this helps!<br>
If you end up modeling in a different way, please let me know. I would be interested to know.<br>Regards,<br>Yuvaraj<br><br>________________________________<br><br>From: <a href="mailto:bldg-sim-bounces@lists.onebuilding.org">bldg-sim-bounces@lists.onebuilding.org</a> [mailto:<a href="mailto:bldg-sim-bounces@lists.onebuilding.org">bldg-sim-bounces@lists.onebuilding.org</a>] On Behalf Of Nuno Brandao<br>
