Things to consider… • The ‘link’ between the PHPP and DesignPH is not ‘live’. It’s a one-way export from DesignPH into the PHPP. • If you change something in PHPP, it does not change in the DesignPH model. • It may (often) be easier to experiment with building variants in PHPP rather than DesignPH. • You’ll still have many inputs that need to be completed in the PHPP after import (DHW, Cooling, PER, Variants, etc…)

Things to consider… • DesignPH simulation results preview in Sketchup are approximate only. PHPP is the more accurate. • DesignPH doesn’t give any preview results for cooling or Primary Energy • DesignPH has no inputs for DHW, appliances, etc… • DesignPH has no inputs for Non-Residential • DesignPH is an EXPORTER. Not a replacement for the PHPP bldgtyp
