Novel super-reduced, pedagogical model for scoping net zero buildings

Since early-stage decisions have the largest impact on climate related emissions, if modelling is to help deliver zero carbon designs, tools are needed that can be used by those involved at this stage. By contrast, require a detailed description of building or specialist less usefulness point in design cycle. So, just how simple models (mathematically and interface-wise), give meaningful answers such as shape glazing ratio? The ideal tool would pedagogical leave user with knowledge they could apply even earlier next project. In work we present ZEBRA, highly simplified, quick-to-use, model for scoping zero-carbon buildings. only requires approximately 33 inputs, no training, considers embodied emissions renewables leaves upskilled design. predictions from 5 very low energy buildings placed into 559 climates obtained new compared leading high-performing average difference was 0.9 kWh·m?2·a?1 (SD = 0.6). mean time taken someone not previously exposed ZEBRA 35 min 8), 17 3) second use. Therefore, accurate when best-in-class quickly uninitiated. Hence has potential useful first-pass whilst simultaneously rapidly upskilling industry.
