<div><br></div><div>1. We have modeled a boiler with 82% <b>combustion efficiency</b> in eQUEST with HIR = 1.219 which is just the inverse of boiler efficiency . But from LEED reviewer, we got comment saying that, HIR of 1.219 is equivalent to 77% efficiency. Could you please let us know, how to convert combustion efficiency to HIR</div>
<div><br></div><div>2. We have two buildings, one is Main Office building (7 day week, 8hr running and Air-Conditioned, Main Office building has 5 to 7% of total two building areas) and the other is Factory+Office building (7 day week, Factory is 24 hr running and Air-Conditioned with 100% of occupancy, lighting and equipment on all the time. While the Factory's Office is 24hr running and Air-Conditioned with 50% of occupancy, lighting and equipment on all the time) which are connected by enclosed bridge (air conditioned). These buildings are modeled together in eQUEST and it comes to be System 7 (Boiler for heating) as per Table G 3.1.1. After reading it for many number of times and to confirm my understanding of the section, doubts are as follows on ASHRAE Appendix G Section G3.1.1</div>
<div><br></div><div> - What should be the system type for Main Office building (Conditioned area is around 45000 Sq ft)? and let me know the exception of G3.1.1 if any gets applied</div><div>
- What should be the system type for factory's Ground Floor Office building? (Area is around 150000 Sq ft) and Does the exception "Schedules that differ by 40 <b>equivalent </b>full load hours" gets applied? since the diversity is 50% for factory's office, if this exception is not applicable, let me know how the equivalent full load hours need to be calculated )</div>
<div> - What should be the system type for Factory's First Floor office building? (This floor is total office, and ground floor factory area is of double height from ground)</div><div> - Does the exceptions of Section G 3.1.1 applies at building level or at each system level? Exception "b" says both the things, so there is confusion<br>
</div><div> - Does the term "Peak thermal loads" in exception "b" consider the load added due to outside air as well?<br></div><div><br></div><div>Let me know, if you need any further clarification to resolve my doubts.</div>
<div><br></div><div>Thanks,</div><div>Vamshi.</div></div>
