The Impact

The buffer effect provided by an atrium is one typical passive strategy used in sustainable building design. Based on a comprehensive evaluation framework that includes both satisfaction and comfort, this research develops two types of graphical visualisation info-graphs. One is a compass reflecting the occupant satisfaction voting, which conveys the level of satisfaction occupants have with the architectural design. The results reflect the health level of the occupants, as well as how efficiently resources are used. The second info-graph is a data cloud that can be used to display a building’s physical environment, and thus convey the distribution of the characteristics of physical environment, such as thermal comfort, lighting, and the acoustic and indoor air quality throughout the entire building. This data cloud directly displays the impact of the passive space on the main building space. Its results illustrate how effectively the building’s indoor environment provides the required levels of occupant comfort and quality of life. Finally, this research uses an example of a green building in a cold climate in China to display its unique method of graphical visualisation analysis. The results highlight the level of environmental performance of the object building in two kinds of info-graphs, as well as optimised possibilities for the atrium and the entire building in both the design and renovation phases.

The Impact

Objectives, Purpose, or Aim: This article investigates whether the physical environment in which childbirth occurs impacts the intrapartum intervention rates and how this might happen. The study explores the spatial physical characteristics that can support the design of spaces to promote the health and well-being of women, their supporters, and maternity care professionals. Background: Medical interventions during childbirth have consequences for the health of women and babies in the immediate and long term. The increase in interventions is multifactorial and may be influenced by the model of care adopted, the relationships between caregivers and the organizational culture, which is made up of many factors, including the built environment. In the field of birth architecture research, there is a gap in the description of the physical characteristics of birth environments that impact users’ health. Method: A scoping review on the topic was performed to understand the direct and indirect impacts of the physical environment on birth intervention rates. Results and Discussion: The findings are organized into three tables reporting the influence that the physical characteristics of a space might have on people’s behaviors, experiences, practices and birth health outcomes. Eight building spaces that require further investigation and research were highlighted: unit layout configuration, midwives’ hub/desk, social room, birth philosophy vectors, configuration of the birth room, size and shape of the birth room, filter, and sensory elements. Conclusions: The findings show the importance of considering the physical environment in maternity care and that further interdisciplinary studies focused on architectural design are needed to enrich the knowledge and evidence on this topic and to develop accurate recommendations for designers.

Abstract The impact of the Belt and Road Initiative (BRI) to global development will be unprecedented and significant, and developmental impact evaluation is therefore central to understanding BRI projects and making informed decisions. Compared with evaluations of individual projects and programs, evaluation of large and mega infrastructure projects under the BRI is particularly challenging and complex in integrating stakeholder objectives, accounting for social benefit and costs, and tracking long-term project impact. In this paper, we summarize the key drawbacks of existing BRI evaluation frameworks, propose a systematic evaluation framework elicitation method based on the inputs from BRI subject matter experts and verified through stakeholder participation, and apply an interim evaluation framework in understanding the Mombasa-Nairobi Standard Gauge Railway project in Kenya, as a proof of concept of a comprehensive evaluation framework. In doing so, we seek to provide a tool for BRI decision makers and stakeholders to assess these projects holistically at planning, construction and operation stages.

Bird Collisions

Green buildings should respect nature and endeavor to mitigate harmful effects to the environment and occupants. This is often interpreted as creating sustainable sites, consuming less energy and water, reusing materials, and providing excellent indoor environmental quality. Environmentally friendly buildings should also consider literally the impact that they have on birds, millions of them. A major factor in bird collisions with buildings is the choice of building materials. These choices are usually made by the architect who may not be aware of the issue or may be looking for guidance from certification programs such as LEED. As a proof of concept for an educational tool, we developed a software-assisted approach to characterize whether a proposed building design would earn a point for the LEED Pilot Credit 55: Avoiding Bird Collisions. Using the visual programming language Dynamo with the common building information modeling software Revit, we automated the assessment of designs. The approach depends on parameters that incorporate assessments of bird threat for façade materials, analyzes building geometry relative to materials, and processes user input on building operation to produce the assessment.

Purpose The purpose of this paper is to explore and rank the benefits and barriers (technological and non-technological) of using Building Information Modelling (BIM) in sustainable building design. It also employs the use of a design tool analysis of a case study using BIM compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North. Design/methodology/approach The paper explores the benefits and barriers of using BIM through a literature review. Regression and factor analysis were used to rank these benefits and barriers. A questionnaire was distributed to a sample of 120 practitioners with 69 completing the survey. Finally, the paper employs the use of a design tool analysis of a case study using BIM-compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North riverside. Findings The key findings of the statistical analysis indicated that professionals ranked the integrated project delivery as the most established benefit, while the lack of interoperability was ranked the greatest technological challenge. Only three of the attributes of non-technological challenges made statistically unique contributions, namely, training costs and software costs, client demand and potential legal issues. It was also discovered that BIM delivers information needed for environmental performance. In a forward-looking approach, the paper attempts to provide some recommendations that would encourage the continuous application of BIM in sustainable building design. Research limitations/implications This paper does not cover all features of BIM functionality, as the scope of BIM is very enormous and the resources of this research were limited. Practical implications The implication of the study is that it will assist in exploring and ranking the benefits and barriers (technological and non-technological) of using BIM while proffering recommendations for future use. This research will be of interest to industry practitioners and academic researchers with an interest in building information modelling. Originality/value This paper contributes with new outlooks aimed at syndicating sustainability with environmental performance and adds to the limited empirical studies on the benefits and barriers of the application of BIM.

The Impact

The quality of most buildings may be affected during the initial phase of architectural design. It is therefore to optimize input parameters, which significantly influence energy efficiency. In principle it is possible to speak of a deterministic approach, which consider the input parameters to be fixed or a stochastic approach, which takes a wider set of input parameters into account. A single-storey house is evaluated in terms of energy performance in the initial phase of building design, where input parameters are changed in order to determine a correlation coefficient. The methodology is based on a sensitivity analysis (SA) and MonteCarlo simulation based on a stochastic random selection. Regression (RA) were written to express the impact architectural design has on energy performance. Feedback from the regression model estimates annual heating demand of single storey house.

Abstract. Processes that describe the distribution of vegetation and ecosystem succession after disturbance are an important component of dynamic global vegetation models (DGVMs). The vegetation dynamics module (ORC-VD) within the process-based ecosystem model ORCHIDEE (Organizing Carbon and Hydrology in Dynamic Ecosystems) has not been updated and evaluated since many years and does not match the progress in modeling the rest of the physical and biogeochemical processes. Therefore, ORC-VD is known to produce unrealistic results. This study presents a new parameterization of ORC-VD for mid-to-high latitude regions in the Northern Hemisphere, including processes that influence the existence, mortality and competition between tree functional types. A new set of metrics is also proposed to quantify the performance of ORC-VD, using up to five different datasets of satellite land cover, forest biomass from remote sensing and inventories, a data-driven estimate of gross primary productivity (GPP) and two gridded datasets of soil organic carbon content. The scoring of ORC-VD derived from these metrics integrates uncertainties in the observational datasets. This multi-dataset evaluation framework is a generic method that could be applied to the evaluation of other DGVM models. The results of the original ORC-VD published in 2005 for mid-to-high latitudes and of the new parameterization are evaluated against the above-described datasets. Significant improvements were found in the modeling of the distribution of tree functional types north of 40° N. Three additional sensitivity runs were carried out to separate the impact of different processes or drivers on simulated vegetation distribution, including soil freezing which limits net primary production through soil moisture availability in the root zone, elevated CO2 concentration since 1850, and the return frequency of cold climate extremes causing tree mortality during the spin-up phase of the model.
