Determine the Overall Heat Loss

6m 42s

In this ARE 5.0 NCARB-approved Project Development and Documentation Exam Prep course you will learn about the topics covered in the ARE 5.0 PDD exam division. A complete and comprehensive curriculum, this course will touch on each of the NCARB objectives for the ARE 5.0 Project Development and Documentation Exam.

Instructor Mike Newman will discuss issues related to the development of design concepts, the evaluation of materials and technologies, selection of appropriate construction techniques, and appropriate construction documentation.

When you are done with this course, you will have a thorough understanding of the content covered in the ARE 5.0 Project Development and Documentation Exam including integration of civil, structural, mechanical, electrical, plumbing, and specialty systems into overall project design and documentation.

And, then, we're gonna do a similar thing for the infiltration and for the ventilation if we're doing anything for ventilation in this, and we're gonna be able to add up those total numbers and have a full total BTU heat loss that we're compensating with our heating system or our cooling system, so, from this, once we have that total loss, we now know how much energy in total through a year, now obviously it's averaged, so it's not necessarily an exact number, that we're saying this is what it would be generally, typically, on a typical year, so we have a pretty darn good idea of what the total heat loss is gonna be for that year, so, therefore, we have a pretty good idea of how much heat we're gonna have to put into the system through our heating system or cooling system if we're talking the other way, and if we understand the cost of the fuel, well, if we know how much the heat loss is gonna be, we know how much heat we have to put in, and we know how much the fuel costs, and we know how much heat we get out of the fuel, we could figure our what our annual costs are and so we can determine what our total fuel use and costs to get that fuel, we could have all of that sort of figured out for us. So, not only would that be useful because it's just handy to know how much everything's gonna cost, but also, if we're trying to do any sort of lifecycle comparisons, so let's say we have two different systems that we're considering putting in for one project, if we just look at, say, the first cost and the efficiency of the unit, well that'll tell us something, first cost, one's gonna be more expensive than the other and in terms of straight efficiency, one will presumably be more efficient than the other, but that isn't really all that telling. What we really wanna know is what in terms of the actual use, how much will that efficiency be meaningful over the span of the year.
