After two rounds of review our model was denied because according to the reviewer’s comment it still “it remains unclear whether the energy savings modeled for space heating are justified”. The project claims a reduction in heating energy by 95%. However, we did address all comments of the preliminary review and additionally the issues described as outstanding in the final design review do not seem substantiated. The comments at the final review do not indicate particular errors in the process but only generic comments with some of them having being totally misinterpreted by the reviewer. Moreover, after having used a similar approach to various other projects we are trying to understand what would be the best approach to resolve this issue. Would it be possible to speak directly to the reviewer?
