I running simulation for a house on different configurations, I ran without HVAC system and I got a Kwh/year, the I ran with a HVAC and I got more kwh/year. Í chanced the configuration on 2 ways adding a green roof and a water proof paint, but I got the same kwh/year as with HVAC, does anyone knows how to fix it?

Title could be made more descriptive. It isn't really a question the reports or how to use them, it seems to be about why you don't get the values you expect with cool roof and water proof paint.

To the question of the results, it is a little confusing what the last two models look like. There is model (A) without HVAC. Model (B) which is the same as A but with HVAC. It seems there is a model (C) that has green roof and model (D) that has water proof paint. Are those both variations on model (B)? I wouldn't expect the paint to do much, but more details on the roof modeling would be helpful.

There are variations in models, as you described; I get the same kWh/yr on models B, C, D. I changed these models to simulated if we have change for kWh

Is the roof in models B-D set to be exterior and set as sun exposed. Do you also have a non-zero heat and cooling consumption in model B? What property are you changing of construction to show it as waterproof? and how would you expect that to impact energy use?

Is the roof in models B-D set to be exterior and set as sun exposed? yes, I´m setting for exterior Do you also have a non-zero heat and cooling consumption in model B? I get consumption for heating and cooling for this model What property are you changing of construction to show it as waterproof? I set construction with concrete, stucco, and waterproof paint to simulate this house adding this material as waterproof paint and how would you expect that to impact energy use? I expected to get less energy use on all of them or different consumption anergy

Next step, I would report out hourly inside and outside surface temperatures, as well as zone temperatures. You can view the SQL Dview or another application. This should help to identify where things are breakdown down. Is the outside surface temperature changing between the models? If it is changing, is the inside surface temperature changing. If that is changing is the zone temperature changing?
