📌 Use of LoD decision plan in BIM-projects
@Reference_Energy
🔺A B S T R A C T
Building Information Modelling (BIM) is new to many companies, and the implementation is consequently challenging. Challenges include unstructured processes that often leads to time and cost overruns. This study assesses how the creative design processes can be scheduled in projects using BIM tools. More specifically, it seeks methods that assures a proper schedule by decision planning. One of the decision tools studied uses the theoretical concept of Level of Development (LoD) to structure design processes. This paper is based upon a literature review followed by four case studies. The cases, which are all using BIM, are studied through interviews and document studies of execution plans, decision plans and BIM-manuals. Three general interviews and twelve semi-structured interviews were conducted with key personnel from owners, contractors and consultants. The study reveals that decision plans are seldom used in the design process and decisions about design elements are seldom formally locked during the process. This demands much from the design manager who has to point out the critical path to assure keeping schedule. It also reveals that several models are delivered with a higher or lower LoD-level than necessary. This can lead to a high number of change orders. The paper concludes with a conceptual model of a LoD decision plan. Furthermore, the findings show that such a LoD decision plan can help owners, designers and contractors to communicate decisions in a timely manner and control the design process. In the long run, the conceptual model facilitates for knowledge transfer from one project to another. It is not common to use LoD decision plan in Norwegian BIM-projects. This conceptual model can be of use for companies who want better control over their BIM design processes

📌 Using BIM to Retrofit Existing Buildings
@Reference_Energy
🔺A B S T R A C T
A large number of ongoing research programs are looking into the implementation of Building Information Modelling (BIM) platforms to optimize design and construction processes. BIM based tools (e.g., Bentley AECOsim Building Designer, Tekla Structures, Autodesk Revit’s Architecture, Structure, MEP, and Navisworks) can handle numerous types of data input (e.g., 3-D design, energy models, schedules, cost estimates) and offer rigorous simulation and visualization options in an integrated manner allowing engineers and contractors to track and control their projects effectively. A similar set of research projects are investigating the use of sustainability principles (e.g., waste reduction, energy savings, healthy indoor environment) to optimize the management of projects throughout design and construction. The link between BIM and sustainability has been flagged in the literature especially in energy-driven retrofits. Nonetheless, the application of BIM to retrofit existing buildings faces challenges which could be due to the multi-disciplinary nature of information exchange, the timeliness of the exchange, and the wide array of technological components that are needed to ensure an optimal exchange. This paper describes, through a critical review of the literature, the areas which are mostly covered under BIM and sustainability. The purpose of this paper is to examine the overlap between the two topics where BIM offers a platform for reducing energy consumption in existing buildings. Finally, a research agenda on enhancing the role of BIM in energy-driven renovations is proposed.

📌 Sustainability assessment through green BIM for environmental, social and economic efficiency
@Reference_Energy
🔺A B S T R A C T
BIM is representing a shift in the traditional process of building delivery. Its adoption in US reached 71% in 2012 rising from 17% in 2007; moreover, Europe is going to adopt BIM for public contracting as promoted by the European Union Public Procurement Directive. Meanwhile, BIM is widely diffused in UK and Northern Europe, as it includes a more accurate documentation, less rework and shorter project timelines. The use of BIM to provide data for energy performance evaluation and sustainability assessment is defined Green BIM and pioneering design organizations are adopting this approach to enable integrated design, construction and maintenance towards Net Zero Energy buildings. Green BIM includes Building Energy Modelling dealing with project energy performance to identify options optimising building energy efficiency during the life cycle. By allowing revisions during the design phase, project teams can ensure that customers’ green ambitions beyond regulation compliance can be realized, together with technical and economic requirements. Thus, BIM can provide information to support the calculation of a number of credit points to define goal levels of sustainability related to rating systems. The aim of the paper is to investigate the opportunity to include the “green dimension” in BIM considering the more diffused rating systems.

♻️ انرژی های تجدیدپذیر برای هند پول و آبرو آورد
✅ هند سال گذشته با پشت سر گذاشتن ژاپن، چین و آمریکا توانست به چهارمین بازار بزرگ انرژی خورشیدی جهان تبدیل شود. این در حالیست که نارندرا مودی نخست وزیر این کشور هدف تولید 100 گیگا وات برق از منابع خورشیدی در سال 2022 را مطرح کرده است.
✅ دهلی نو در حال حاضر بر روی ساخت یک پارک خورشیدی وسیع به نام پاواگادا در جنوب این کشور کار می کند که انتظار می رود پس از بهره برداری با تولید دو هزار مگاوات، بزرگترین ایستگاه نیروی برق خورشیدی جهان باشد.
✅ ساخت این نیروگاه های خورشیدی تنها بخشی از برنامه های هند برای مطرح کردن خود به عنوان یک قطب اصلی مبارزه با آلودگی های کره زمین در غیاب آمریکا است. واشنگتن با نادیده گرفتن توصیه های کارشناسان سال گذشته با دستور مستقیم دونالد ترامپ رئیس جمهوری این کشور تصمیم گرفت از معاهده بین المللی آب و هوا خارج شود.

📌 استانداردهای ملی سیستم برق خورشیدی و پنل خورشیدی
به گزارش برق نیوز، با توجه به وجود مجموعه استانداردهای تبیین شده از سوی سازمانهای استاندارد جهانی، پارامترهایی مانند شرایط محیطی مانع از جامعیت چنین استانداردهایی میگردد و برای همین سازمان استاندارد ملی هر کشور، مجموعههایی را در نظر میگیرند که میتواند به عنوان مکملی در کنار استانداردهای جهانی در نظر گرفته شوند.
🔹استانداردهای ملی ایران مربوط به ماژولهای فتوولتاییک
🔹استانداردهای ملی ایران مربوط به سلولهای فتوولتاییک
🔹استانداردهای ملی ایران مربوط به قطعات سیستم فتوولتاییک
🔹استانداردهای ملی ایران مربوط به کلیات سیستم فتوولتاییک
🔺ساتبا در فایل زیر فهرستی از استانداردهای ملی در حوزه انرژیهای تجدیدپذیر ارایه کرده است.
📌جزییات مجموعه استانداردهای فوق را میبایست در طراحی، ساخت، نصب و پشتیبانی پکیج برق خورشیدی استفاده نمود.
