HDD and internal gain.

HDD and internal gain.Using a standard 5° allowance for internal gain, base 65°, is a rough enough approximation from the start. But to use it for both test-in and test-out introduces a known…Continue

The Short-Circuit Theory, Keep or Remove Those Gable Vents?

Bud Poll replied to Bud Poll's discussion HDD and internal gain."Hi James,
The BizEE web page deals with the inaccuracies of selecting a particular base for one's HDD. What I'm pointing to is the additional error created by presuming the same base used on test-in will be appropriate for test-out. A base…"
James McGarvey replied to Bud Poll's discussion HDD and internal gain."Heating degree days are very miss used. Here is good article on subject http://www.energylens.com/articles/degree-days

Bud Poll replied to Bud Poll's discussion HDD and internal gain."Here's some added thinking/questions.
Q. Does anyone have any real numbers on internal gain and what is and is not considered the source?
Q. Do the majority of EE programs use base 65 and is it used for both test-in and test-out?
Q. If base…"

HDD and internal gain.Using a standard 5° allowance for internal gain, base 65°, is a rough enough approximation from the start. But to use it for both test-in and test-out introduces a known error. Since the math for that -5° produces a percentage of the heat loss, the "new and improved home" results in a smaller test out allowance for internal gain. My thoughts are, we should try to be consistent and use the same allowance for both before and after tests, adjusted for any known…See More

Bud Poll replied to Patrick Michaelyan's discussion Hot Upper Stories"Hi Patrick,
Give us a big city so we will know what climate zone you are dealing with, summer and or winter heat. A few years back I worked with a home owner who had over 3' of attic insulation, but his problems hadn't changed. …"
Bud Poll replied to Melissa Baldridge's discussion Changing 80 Percent Furnaces to 90+"Hi Melissa,
I'm sure others will weigh in here, but I always find it interesting to test this change with current and improved energy efficiency. Often the saving for the change is difficult to justify once the home becomes very well…"
Bud Poll replied to Bud Poll's discussion Attic ventilation with mixed soffit heights. in the group Best Practices (Residential)"Bob, what do you use for guidelines for ventilation, 1/300 with 40% high and 60% low? Where do you want the air to enter and exit? I would assume some of your buildings, new and old, have soffits located all over the place, so given your preference…"
Bob Blanchette replied to Bud Poll's discussion Attic ventilation with mixed soffit heights. in the group Best Practices (Residential)"In our area attic ventilation is primarily about not overheating the attic, ice dams aren't an issue for us. There is almost always a breeze of at least 5MPH, south in summer, north in winter. If the wind shifts in the day the temperature can…"
Bud Poll replied to Bud Poll's discussion Attic ventilation with mixed soffit heights. in the group Best Practices (Residential)"Hi Bob, I agree that there are other factors that must be considered when deciding upon how much and where our venting should be, but natural air flow is still part of the equation and the NPP is important, especially when the standard advice is…"
Bob Blanchette replied to Bud Poll's discussion Attic ventilation with mixed soffit heights. in the group Best Practices (Residential)"I've found even a mild wind of 5MPH throws all the NPP theories straight out the window. Structure your vents to work with the prevailing wind rather than NPP if you live a windy climate."
Bud Poll replied to Bud Poll's discussion Attic ventilation with mixed soffit heights. in the group Best Practices (Residential)"I've made some progress on how to assign the vent areas to achieve the air flow direction we want. There will eventually be some associated math, but for now the basic logic will at least provide some guidance, and note, that guidance is…"
Bud Poll replied to Tom Delconte's discussion Energy Myths- Fact or Fiction?"Hi Tom, I always enjoy myth busting as it is often amazing and amusing how they grow and take root. I'd like to add a couple of my favorites which are well rooted yet need to be corrected as they are very important to our energy profession.

Bud Poll replied to Nick Helmholdt's discussion Backup Power for Pump on Radiant Heat System"Hi Nick,
I'm way out of my comfort zone discussing HVAC, but I have run into a couple of situations where check valves failed to close and the resulting convective flow of water resulted in over heating the affected area. Install the ability to…"
Bud Poll replied to Andrew Aliferis's discussion Cost of training and certification"Hi Andrew, It's not. At the start there was a rush to create 10,000 auditors in two weeks, (I'm exaggerating), we needed to "SAVE ENERGY" at all cost, and if the process created extra jobs, training, certification, verification,…"
