“…(3) The average GHG impact of all project design possibilities within one zone is calculated, followed by the calculation of the available GHG impact in accordance with the building area and usage, as defined by SIA2040 norm. Contextual targets are then calculated by attributing the share of the total site impact proportionally to the average impact of each zone (Nault et al 2020).…”

Target values for creating carbon budgets for buildings are important for developing climateneutral building stocks. A lack of clarity currently exists for defining carbon budgets for buildings and what constitutes a unit of assessment-particularly the distinction between production-and consumption-based accounting. These different perspectives on the system and the function that is assessed hinder a clear and commonly agreed definition of 'carbon budgets' for building construction and operation. This paper explores the processes for establishing a carbon budget for residential and non-residential buildings. A detailed review of current approaches to budget allocation is presented. The temporal and spatial scales of evaluation are considered as well as the distribution rules for sharing the budget between parties or activities. This analysis highlights the crucial need to define the temporal scale, the roles of buildings as physical artefacts and their economic activities. A framework is proposed to accommodate these different perspectives and spatio-temporal scales towards harmonised and comparable cross-sectoral budget definitions. Policy relevance The potential to develop, implement and monitor greenhouse gas-related policies and strategies for buildings will depend on the provision of clear targets. Based on global limits, a carbon budget can establish system boundaries and scalable targets. An operational framework is presented that clarifies greenhouse gas targets for buildings in the different parts of the world that is adaptable to the context and circumstances of a particular place. A carbon budget can enable national regulators to set feasible and legally binding requirements. This will assist the many different stakeholders responsible for decisions on buildings to coordinate and incorporate their specific responsibility at one specific level or scale of activity to ensure overall compliance. Therefore, determining a task specific carbon budget requires an appropriate management of the global carbon budget to ensure that specific budgets overlap, but that the sum of them is equal to the available global budget without double-counting.

“…Although similar thermal zones were considered in each building, the simulated EUIs were considerably varied among the buildings in each stock. In addition to the description of such variations for lighting systems and equipment (Section 3.2), solar heat gain and loss through the different WWRs, external wall composition, and orientation of the buildings can contribute to the differences (for HVAC systems) [45,70]. The PDF of the simulated EUIs for the studied building stocks followed a lognormal distribution (Figure 8).…”

Urban building energy models (UBEMs), developed to understand the energy performance of building stocks of a region, can aid in key decisions related to energy policy and climate change solutions. However, creating a city-scale UBEM is challenging due to the requirements of diverse geometric and non-geometric datasets. Thus, we aimed to further elucidate the process of creating a UBEM with disparate and scarce data based on a bottom-up, physics-based approach. We focused on three typically overlooked but functionally important commercial building stocks, which are sales and shopping, healthcare facilities, and food sales and services, in the region of Pittsburgh, Pennsylvania. We harvested relevant local building information and employed photogrammetry and image processing. We created archetypes for key building types, designed 3D buildings with SketchUp, and performed an energy analysis using EnergyPlus. The average annual simulated energy use intensities (EUIs) were 528 kWh/m2, 822 kWh/m2, and 2894 kWh/m2 for sales and shopping, healthcare facilities, and food sales and services, respectively. In addition to variations found in the simulated energy use pattern among the stocks, considerable variations were observed within buildings of the same stock. About 9% and 11% errors were observed for sales and shopping and healthcare facilities when validating the simulated results with the actual data. The suggested energy conservation measures could reduce the annual EUI by 10–26% depending on the building use type. The UBEM results can assist in finding energy-efficient retrofit solutions with respect to the energy and carbon reduction goal for commercial building stocks at the city scale. The limitations highlighted may be considered for higher accuracy, and the UBEM has a high potential to integrate with urban climate and energy models, circular economy, and life cycle assessment for sustainable urban planning.

“…Yet there appears to be general agreement among those seeking a definition of environmental secondary analysis that it should include the study of data that has already been collected by another researcher and is open to further investigation (Li and Wang, 2022). Other professionals and researchers highlight the environmental secondary analysis's ubiquity as a set of research endeavours that make use of existing resources rather than a particular regime of analytical techniques or statistical technique (Nault et al, 2020). Nevertheless, other researchers point out how environmental secondary data analysis requires the use of innovative analytical techniques to data that has already been obtained by others, which distinguishes it from primary data analysis, which involves both data collection and examination (Li and Wang, 2022).…”

Assessing environmental major development projects requires using advanced levels of environmental secondary data (ESD). This is particularly challenging in developing countries. Hence, a systemic literature review was performed. Along with structured interviews and online questionnaire designed for professional planners and researchers were used to investigate the factors affecting secondary data collection and processing for environmental assessment systems in Egypt as an example of developing countries revealing potentials and challenges. The results pinpointed critical problems for ESD associated with poor sufficiency, availability, relevance, and accuracy of data. Thus, using these four defined criteria, an assessment framework was developed to evaluate the status of ESD for development projects. This provides guidelines for establishing an integrated data collection and management system to support the environmental assessment process. This is further applied to 'Elqattara depression national development project' to investigate the environmental impact of various desalination development scenarios. This case study project pinpointed problems for the ESD used related to both relevance and sufficiency.
