I am carrying out a research project simplified building energy modelling tools, and I am looking for simplified tools that provides reasonably accurate estimates of annual energy consumption (isn't everyone ;-). Ideally the tool would allow for the input of approximate building geometry and floor area, envelope performance (perhaps a way to choose from different constructions), lighting, equipment and occupant loads, and some way of selecting different HVAC system types and efficiencies. I know in Canada we have RETScreen and the Screening Tool. Are there similar such tools developed for US/Europe that you might recommend investigating?
Thank you, Dan
