The actual cooling loads are smaller than the heat gains while the lights are on. This is because a large portion of the heat gain is thermal radiation. This radiant heat is absorbed by the mass or the floor, walls and furnishings in the room, stores in the mass and then released by convection to the room air where it then becomes a cooling loads. This process causes a delay between the time a heat gain occurs and the time its full effects as a cooling load.<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US>The lighting we are modeling is "recessed unvented", and it shows the lowest amount of direct heat gain to the space. During the first hour, 0700 of the total heat gain, approximately 66 % becomes an instantaneous space load by convection, while the remaining 34% of the heat gain is either convected into the ceiling space above or into the room directly. The remaining load is radiant energy, which is stored in the room mass and released over time. The cooling loads continue long after lights are turned off, at 1600 hs. This is due to the radiant heat and the heat storage effects. When the lights are turned off, some radiant heat from the previous nine hours is still stored in the room mass and continues to be convected to the room air over time.<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US>This is why scheduled lights, where they are on for say 8-10 hours per day, then off the remainder of the time, can result in more quantity of hours of operation than the ones that were scheduled.<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US>I would appreciate your opinion on the thoughts above.<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US>Thank you,<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US>Paula Hernández<o:p></o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US style='mso-fareast-language:ES-AR'><o:p> </o:p></span></p><p class=MsoPlainText><span lang=EN-US style='mso-fareast-language:ES-AR'>Ingeniera Paula Andrea Hernández LEED AP (BD +C) / Edge Exper</span><span style='mso-fareast-language:ES-AR'>t & Auditor<o:p></o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'>Capitulo Argentino de ASHRAE <o:p></o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'><o:p> </o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'>Estudio Ingeniero Mario Pedro Hernández<o:p></o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'>Cel: 11 1559221377 (+54 9 1159221377)<o:p></o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'>Tel.: 11 1544712688 (+54 11 944712688)<o:p></o:p></span></p><p class=MsoPlainText><span style='mso-fareast-language:ES-AR'>Av.
