"Good data will provide good analysis. Monthly energy bills and weather data from a local airport will only get you in the same town as the ball park. Actual delta T's and hourly fuel consumption will get you to home plate. The…"
I collect hourly energy use data using a TED 5000 for electric use and Lascar EL-USB-5 event data logger that is connected to the pulse output of an Elster BK-4G diaphragm meter for LPG usage. Environmental data is…"
"A four year (hourly) monitoring and verification project has proven the need for passive solar gain calculations in heat dominant climates. We have found up to 45% discrepancy between yearly energy use measured vs. modeled. Wile the heat…"
"Bob, is there a mechanism that compares the amount of gas that enters that pipeline circuit and compares it with the amount that is metered and billed. Accounting for losses in the delivery infrastructure must be included in the rates, but I…"
" Tedkidd might be on to something with program accountability. I recently spent time in the crawl space, of a building that is owned by the government agency that administers the WAP program in my area. I informed the director that…"
"Meg has my attention and I share her philosophy on VERIFICATION. The DOE has become a government beast with many heads and tails. Neither looking in the same direction nor wagging at the same accomplishments. Standardized testing, with…"
"I am curious as to which energy modeling tools have been providing accurate results for the experts in this community? Has anyone reviewed results from Greenbuild Studio (autodesk Revits' cloud based analysis using eplus as its'…"
I have been collecting hourly energy use and environmental data for two homes for nearly four years. One is superinsulated with minimal solar and internal gains (seasonal home) and the other is a passive solar primary…"
"Do not forget to consider Passive Solar Design for heating and day lighting solutions. We can offset 30 to 50% of the annual heating needs (depending on location) with common sense design. A proper design will also temper the summer…"
"Extruded (of course). I also like the way that you achieve the R15 edge requirement. I have modeled energy loss comparing 2" XPS with 1" XPS in well drained + soils climate zone 6. and have reservations about the added cost of…"
"Do you have a moisture barrier below the slabs' EPS? I have found that a 1" layer of sand, placed over the EPS helped to protect both the insulation and vapor barrier. This may have also provided some amount of moisture control…"
"Can you describe your data acquisition method and sensor type/location. I just completed 24 months of hourly monitoring on a passive solar residential building and have a Very large excel file of data that has been evaluated in many different…"
" I just left a job site where the builder is convinced that he followed the IECC 2009 heated slab on grade specifications for zone 6 (Montana). He passed local inspections so I am now second guessing myself. He has 2 inch EPS …"
