"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 …"
"Does the home have its' own well?? This can often be wired to the main service entrance which might place it in front of your metering equipment. Well pumps and automated lawn irrigation can require a significant load increase an could…"
"We're in the same ballpark but we might be on different teams. More likely due to location than ideology. I also rely on thermal load calculations and am particularly vested in solar impacts in a heat dominant climate. I have …"
" The MPG analogy has been a concern for those of us that design and build Passive Solar homes. A blower door test and a check list just didn't present the real energy consumption of these types of homes and most modeling programs…"
"I believe that consumer access to smart metering data (gas, electric, etc.), combined with environmental monitoring, can give consumers the same desire to embrace energy efficiency that speedometers and fuel gauges have given them in their…"
