IEA PVPS BIPV Design and Performance Modelling: Tools and Methods
Abstract and Figures
The given state-of-the-art review of BIPV design and management tools presents recent developments in BIPV modelling concerning design and management processes with different levels of detail, targeting various stakeholders and their requirements in the BIPV value chain in relation to geophysical, technical, economic and environmental aspects. It goes beyond focusing only on PV modelling and gives an overview of the BIPV tools from the perspective of BIPV integration in design and multi-performance modelling and planning. The report examines features and functions, as well as potential development
and limitations of currently available tools used in BIPV planning process, including tools specifically designed for BIPV and PV tools with capacity to simulate certain BIPV cases. Moreover, report provides information on limitation and reliability of these tools in different settings and for different BIPV categories, indicating pathways and tools’ selection that would provide the highest confidence and fidelity of results as well as positive user experience throughout the process. The report streamlines workflows according to the type and complexity of BIPV integration and offers pathways and tools suitable for required case. The report included 15 domains of BIPV planning such as
geophysical, technical, economic and environment which affect successful BIPV integration. 27 software, 9 online tools and 4 apps were compared against the aforementioned domains.
The findings of this review showed none of the examined software and apps can cater to all the factors pertaining to PV project design and management. Results have shown that majority of tools used in BIPV modelling come from PV domain and consequently still lack important features regarding BIPV integration, especially for vertical or externally mounted BIPV. Therefore, this study propose a decision support system which will address stakeholders’ practical difficulties by providing the main features: (1) a localized data repository which will include weather information, building regulations, energy consumptions in different building sectors, utility prices,
construction and maintenance costs, contract types, financial modes, carbon prices and government incentive schemes; (2) efficient 3D model creation of the physical environment; (3) Hourly comparison of energy input and output; (4) PV layout design optimization; (5) Simulated installation process and
impact analysis; (6) Monitoring and inspection modules with auto diagnosing function; (7) PV system performance recording; and (8) sensitivity analysis and scenario-based decision making support.

... Hence, the surface temperature and emission of longwave radiation of the photovoltaic façade is lowered. It still remains inconclusive which aggregated effect results 7 . ...
Building facades offer considerable potentials for climate and energy activation in urban areas by means of
vertical greenery systems and photovoltaic facades. The optimal exploitation of these potentials requires a
profound understanding of the interdependencies of the two technologies with the urban microclimate and of
the arising synergies when used in combination. District-wide simulations with green walls and photovoltaic
facades as elements in the urban heat balance can enhance the knowledge. Thus, corresponding modeling
requirements are identified and a modeling workflow combining the strengths of microclimate simulations
and thermal building simulations is derived.
Industrial parks, distributed widely and with high energy consumption, show the demand for and provide favorable conditions of application of photovoltaic(PV) systems in a large-scale. Innovative PV technology allows more building integration options, bringing new opportunities for energy conservation.In the study, an evaluation framework was constructed in order to evaluate the expansion potential of PV systems. Taking the green integrated energy park in North China as an example, the construction and energy supply–demand data were reviewed.The scalable area of PV, the application effect of varied PV technologies and the impact on pollutant emission reduction were quantitatively analyzed. The roofs, facades and sites in the park were divided into seven types, These are then simulated to deploy mono c-Si modules, poly c-Si modules, CdTe film modules and CIGS film modules to obtain the best solutions by comparison. The results shows that the PV expansion of the park has significantly increased the power generation. The proportion of the energy supply meeting the overall energy demand increased from 4.3 % to 25.9 %. The wall of the production area where CdTe standard film modules were deployed is the place with the highest PV potential, followed by the parking shed and other sites. The deployment of diverse PV modules controlled the economic cost. The power generation trend also would better matches the hourly load of the park's power consumption, which can cover the sub item power consumption of the park. After the PV expansion, CO2 emissions would be reduced by 4757.8 t per year. Based on the results, the correlation change characteristics and the influences of PV available area, PV capacity and power generation index are discussed. Considering the declining PV cost and the demonstrative nature of the case Park, the above results can guide the industrial parks to improve the utilization level of renewable energy and promote the realization of carbon emission reduction targets.

This paper provides a theoretical perspective of how modeling and simulation on a CAD platform can be used to teach science concepts and inform design decisions. The paper discusses the educational implications of three recent advancements in CAD technologies: system integration, machine learning, and computational design. The challenges to design energy‐efficient buildings that harness solar energy are used as the engineering examples to illustrate the learning and teaching opportunities created by the modeling, simulation, and data mining capabilities of the Energy3D software, which is a CAD tool developed from scratch along the directions of the three advancements to support engineering research and education. Preliminary results from students in a physics classroom and an online course shed light on the effects of these features on guiding student to design cost‐effective rooftop solar power systems for their own home buildings.
Cityscapes provide a complex environment, where solar radiation is unevenly distributed, especially since urban features started to propagate more and more vertically. Due to the dynamic overshadowing effects present on building surfaces, quantifying these phenomena is essential for predicting reductions in solar radiation availability that can significantly affect potential for solar energy use. Numerical radiation algorithms coupled with GIS tools are a pathway to evaluate those complex effects. Accurate representation of the terrain, vegetation canopy and building structures allows better estimation of shadow patterns. Higher spatial and temporal resolutions deliver more detailed results, but models must compromise between accuracy and computation time. In this paper, models ranging from simple 2D visualization and solar constant methods, to more sophisticated 3D representation and analysis, are reviewed. Web-based solar maps, which rely on the previous features to successfully communicate the benefits of the solar resource to the public and support in the policy-making process, are also addressed.
This report contains notes, observations and recommendations about the use of batteries in small stand-alone photovoltaic (PV) systems. The conclusions of this work are based on the results of more than a decade’s worth of battery testing at the Florida Solar Energy Center and related work with Sandia National Laboratories, the PV industry and user groups. The most critical findings were the relationship between battery state-of-charge and battery life and the importance of an adequate PV array-to-load ratio.
Distributed solar PV design and management in buildings is a complex process which involves multidisciplinary stakeholders with different aims and objectives, ranging from acquiring architectural visual effects to higher solar insolation in given location, efficient energy generation and economic operation and maintenance of the PV system. Therefore, proper PV design tools are necessary for achieving unique aims, objectives and performance goals of a PV project. This paper presents 23 solar PV design and management software and 4 smart phone/tablet applications, analyzing their features against 15 key aspects of solar PV design and management. The results show that the selected PV design and management tools cannot satisfy all aspects of PV design and management. 14 solar PV design and management application problems were identified. An integrated platform which will provide cost-effective solutions for PV project development is proposed at the end of the paper. The proposed platform should open a new outlook on potentially wider multidisciplinary usage of solar PV design and management tools world wide.
