RSC – New Features
ASV gap sizes (11/1/16)
Dynamic roof properties – when a new roof type is
selected, the default reflectance and emittance are
dynamically changed to the average 3-year aged
values for that roof type (from referenced studies);
the user can still change these for their specific roof
RSC – New Features
Copper roof (11/1/16) – a roof type of
“Copper” is now available in both the
residential and commercial calculator
Mouse-over tooltip for roof type shows
the aging of copper from 1-30 years

RSC – Analysis
All non-configurable model inputs (e.g. envelope materials, internal heat sources) were assigned closely to the buildings used in Akbari & Konopacki for comparison
Python analysis file evolved over 43 iterations for conducting parametric analysis of multiple RSC revisions and generating statistics & charts for analysis of RSC simulations
Iterations of ~139 Excel workbooks were generated to aid in the analysis of energy performance and trends as revisions to RSC were made
RSC – Engine modifications
Modification to DOE-2+AtticSim executable
Dynamic duct-sizing
DOE-2 duct model replaces AtticSim’s duct model
AtticSim’s duct model (inspec-R-8, 4% leaky; uninspec-R-5.5,
14% leaky) was changed out for DOE-2’s duct model (inspec-
deltaT 4-degrees, 4%; uninspec-deltaT 6-degrees, 14% leaky)
30+ updated tooltips – text, hyperlinks, images, publications
RSC – Engine modifications
Modifications to all prototype buildings Commercial buildings’ “existing” vintage was changed from PSZ (constant volume system) to PVAVS in order to eliminate inordinate heating penalties; this taints equipment efficiencies compared to earlier versions of RSC
Sizing runs were added to the base case and used in the comparison case so that the same-sized HVAC is used in determining energy savings
Issues under investigation: Energy savings (or penalties) and indoor air temperatures still being investigated
Simulated heating penalties and indoor air temperatures higher than expected, especially in warm climates
RSC more similar to EnergyPlus
than DOE-2
RSC – Comparison to measured data
Standard House (Fresno, CA) Cool Roof House (Fresno, CA)
RSC – Comparison to measured data
1. RSC validated against measured data from
homes and offices (full lit review provided)
2. RSC warning removed
3. Provide all data - comparative parametrics (all
types, locations, ages) as well as measured vs.
simulated data for home & office in Fresno, CA
4. Cool Roof and Cool Peak to remain online
5. DOE-2 (without AtticSim) used for little or no
attic space
