Building Energy Modeling - Algorithmic Design - Extra
14.06.2017 - DAY 3 - CONFERENCE
First day in Ankara started fast. Early in the morning waking up to prepare for conference. Inside Metu (middle east technical university) my friend Uğur take me to a place where is near bus stop to breakfast. 'Arkabahçe' is place that you can get your meal to your plate and you pay as what you got. About 09:00, we get on the ring and arrived to faculty of architecture at 09:10. Conference room is near the entrance of faculty that's how I can find easily the crowd. My thesis partner Gökhan and I were existed th see such an activity about computational design approach. Meeting started at 9.45 with Prof.Dr.Arzu Gönenç speech. She talked about history of MSTAS which started 2007 at same place in the Architecture Faculty of Metu and after that conference has started. There were 10 presentations and the content was big long to explain one by one I will mentionfew about hot topics. Firstly, faculty of architecture has started new tech laboratory wnich students can improve their CAD/CAM skills. Secondly, there were research and discussion about benefits and disadvantages of difital programs for design education and 3d thinking on design. Thirdly, there were another research on education and parametric tools. To additionly, there were doctorate and master research presentations about shape grammars, design production, program evolution. Between presentations, there were questioning sessions, at some part there were discussion about computatiınal design terminology and lack of right usage in turkish language. It was open minding and tiring day. After conference, I came home and directly slept on couch. I hope second day will be good as today the first day and also we will present our research that is totaly fascinating. For today that's it.
How to modify a weather (EPW) file or create new ? Elements is a free, open-source, cross-platform software tool for creating and editing custom weather files for building energy modeling. The goal of the project is to develop a comprehensive, integrated application suitable for handling all of the common tasks associated with weather files. link: http://bigladdersoftware.com/projects/elements/ How to modify a weather (EPW) file with other data? run the weather converter on the original file (Energyplus component) convert the file to "EnergyPlus CSV" (it exist in excel) open the EnergyPlus CSV file in your favorite spreadsheet program. (excel) make the mods, saving it as CSV from the spreadsheet program. run the weather converter again, this time selecting the CSV and make sure the File type is "EnergyPlus CSV" convert it to EPW. link : http://bigladdersoftware.com/epx/docs/8-3/auxiliary-programs/energyplus-weather-file-epw-data-diction
Figure.Thermometer Actual thermal comfort is dependent on environmental factors, such as air temperature , air velocity, relative humidity and the uniformity of conditions, as well as personal factors such as clothing, metabolic heat, acclimatisation, state of health, expectations, and even access to food and drink. Operative temperature (air temperature + mean radiant temperature + air velocity) Operative temperature is indictaion of thermal comfort comes from air temperature , mean radiant temperature and air speed. It is helpful to define or predict thermal comfort for occupants of a building. Basically, thermal comfort is related with environmental elements, which are air temperature , air velocity, relative humidity and the consolidation of conditions, also individual properties such as clothing, metabolic heat, acclimatisation, state of health. In many spaces, with low air velocity and where air temperature and mean radiant tem
Abstract: The urban population increases continuously since the industrial revolution, and the residential buildings have the primary responsibility for the total energy demand. There is a need for the analysis of the residential building stock for energy efficiency and sustainable planning. However, energy modeling and simulation in urban scale is expensive in computational complexity and time, due to various building geometries and occupancy types. This research proposes a method to increase the efficiency of the simulation process by reorganizing the building geometries with functional clustering and radiation analysis scaling. In order to accelerate the urban building energy modeling (UBEM) process, the building geometries are modified based on energy simulation standards, then, clustering is determined based on radiation analysis and outside boundary conditions. The candidates are selected according to the selection percentage that has been identified before the process to simul
