“…Comparison of the methods is on the level of energy demands included and the provided energy balance. In earlier research, the methods were compared on applicability to a wide range of mixed usages, district level, detail, accuracy, energy technologies and possible data inputs [13].…”

“…Also, models need to be able to include energy system and building (use) specifics. One of the main challenges identified in simulating PED energy performance is limited access to reliable input data [13]. A source of input data that can support transparency is the Energy Performance Certificate (EPC) calculation.…”

“…The tool performs detailed hourly simulations of the interaction between buildings, users, and their surroundings to produce energy demand forecasts, and other features. Following a detailed evaluation of various energy modeling tools, CEA can be considered as a middle point between accuracy and detail [13]. To investigate its accuracy we performed a validation study on a single building, before applying it to the PED case study at district level presented in section 3.…”

Positive Energy Districts (PEDs) are potential high-impact climate change mitigation actions towards low carbon or even climate neutral cities. This implies that the energy performance and greenhouse gas emissions of PEDs need to be assessed. To this end, an accounting methodology, metrics, supporting (accounting) tools, and reporting are necessary that capture the full energy and climate impact of PEDs. The European Commission's Building Energy Specification Table (BEST) provides a methodological approach for calculating the energy balance of PEDs. The BEST is a formal requirement of the European Commission’s proposal process, with respect to the Horizon 2020 funding program. An improved methodology for calculating the annual energy balance of a of PED, based on the international standard ISO52000, was developed by the Making City project in 2020. In this paper, we evaluate and compare accounting methods for assessing the energy performance of PEDs and conclude on their use and shortcomings. The hypothesis to be explored is that current accounting practices are based on accounting at a building level and alternative methodologies are needed to capture the full impacts at a district level. To this end, we apply the current approaches on the ATELIER project's PED pilot in Buiksloterham, Amsterdam, which will serve as a case study to illustrate the differences in outcomes and in the use of the results in evaluation and policy making. Consequently, we reflect and recommend on improved approaches and methodologies.

“…Overall, there are no established standard approaches for modelling huge building clusters because the modelling methodologies and frameworks of large-scale building areas and cities are still undeveloped and have many issues and challenges to tackle. A recent comprehensive study by Belda et al [5] has identified the key challenges and limitations of energy modelling software in the assessment of PEDs using five case studies in Denmark, Netherlands, Spain, Italy, and Canada. Recently, a variety of building cluster and city energy modelling approaches have been developed and implemented, allowing the estimation of the energy consumption of building districts and cities on a small-to medium-scale basis [6].…”

The Danish island of “Ærø” has the ambition of becoming the first Danish island to be self-sufficient in renewable energy and CO2 neutral by 2025, as well as fossil fuel free by 2030. This work investigates the feasibility of re-designing part of the island’s energy system to become the first Danish positive energy island (PEI), evaluating various design scenarios and opportunities for improving and modifying the current energy supply and distribution scheme. The district is modelled considering all building specifications and characteristics and the energy supply systems using the urban scale modelling tool City Energy Analyst (CEA). A simulation of the base-case scenario is performed to calibrate the performance. Different energy improvement strategies targeting building envelopes and energy generation and supply systems are created and implemented in CEA. Six improvement packages are created and simulated. It is demonstrated that a PEI could be built in the district under consideration through a comprehensive energy improvement package of envelope-targeting techniques, energy system upgrades, and the expansion of renewable energy systems. The package includes LED lighting, heat pump installation, and photovoltaic-thermal units. This will enable meeting the annual net need for electricity while producing 20% excess heat.
