 In this video about Solar Radiation Analysis in Ecotec, you will learn how to do analysis of solar exposure, how to subdivide your surfaces and how to calculate incident solar radiation on your building. And you will also get insights on analysis results and how these results have impacted this actual design project from Henning-Wassen Architects. In this video about Solar Radiation Analysis in Ecotec, I want to start out in Project Vasari. So just to argumentate why to use Ecotec and not Vasari, in reality I would always use both programs and it's really based on the same equations and calculations functionality with inside Vasari or Ecotec. With inside Vasari we can look at the amount of solar radiation that will hit the surfaces in our model, but we are only able to see the total amount of radiation and we are not able to see the different types of solar radiation, absolved, transmitted and incident as we can in Ecotec and it's also just a lot faster to work with this type of analysis with inside Vasari. One of the key things is that we're not able to work with the scale inside Vasari. That means that we're not able to say okay where is between 350 watts to 750 watts which is something we can do in Ecotec. So starting out I want to take a look at this project from Henning-Wassen Architects and right now we're not able to display the solar radiation analysis on the model. So to see the analysis result we can go to display object attributes to look at the average daily radiation. I do in many cases prefer to look at the average daily values which is more qualitative because it's easier to do comparisons and argumentate for the specific amount of radiation for a specific day. In this project here what we used solar radiation analysis for was really to decide the amount of glacing and to place the glacing on qualitative spaces according to this analysis here. So to do that and show how we work with this we can turn on the facade which consists of closed panels with solar panels embedded and windows here. So what we tried to do was really to first of all to have an equal amount of distribution on the surfaces in the model. As you can see here we have kind of divided the amount of radiation by excluding the volumes in the model. And then what we want to do here is to make the facade more closed where we have more radiation and to make it more open on the north side to have more daylight coming into the building. And there's different ways that we can look at it and we can set to say display text values and we're able to set looking at vectors to have a visual interpretation of where we'll have the most of radiation on the model. So just taking that off and we can also do it from here on the display settings here where we're also able to export the data from the property dialog and then say analyze data to make this cool graph with inside e-project. And the argumentation for taking the data out as numeric data is that we're able to take or pull this data together to do comparisons of different proposals and we are also able to validate the amount of solar radiation that will have hit the different components in the model. A really cool thing about doing this in ecotech is that if we go here to scale we can now begin to work with the scale to say okay I want to see where there is between 350 to 750 watts per square meters here. So that makes it a bit more easy to use the analysis in ecotech and to visualize it in multiple ways. Also in ecotech I'm just hitting out a very simple model that I did. What we can do here is that we can actually go to the analysis tab or to calculate to look at the solar exposure. This is really cool that from the beginning just looking at the site we can get an overall sense of the different months and times a year where we'll have more and lesser solar radiation. And we're also able to hit a specific surface that we can measure this on to say update surface. And now we can really look at the amount of solar radiation that will hit this specific surface in the model. Something that we can do to dimensioning solar panels and stuff like that. So let's take a look at how we actually apply the analysis with the inside ecotech. So here I just have a simple context and the volume or the involvement of the new building. So what I did here was that I went in and subdivided these surfaces by going to modify surface subdivision, rectangular tiles, and then specify the size of the tiles and the way that I wanted it to be aligned on the model. And then I placed these subdivisions in the zone here sub and made that a thermal zone. So the next thing I'll do is I'll go to calculate and say solar access analysis and there is multiple ways that we can look at the amount of radiation inside ecotech. We can look at the incident solar radiation or the absorbed transmitted solar radiation, especially for windows and stuff like that. And we're also able to look at the exterior surfaces, looking at the side, looking at shading or shattering and sunlight hours, which can be quite a good way to look at the amount of radiation coming from the sun. So in this case here, let's just hit the incident solar radiation for a specified period and select the period I want to take a look at the whole year in the time span where we'll assume that people will use the building and say just every daily values because I like this way of looking at it and say only use objects and thermal zones because I placed the objects that I want to simulate on in the zone here and then I want to clear all values in next, say perform detailed shading calculation and then I can store the results for later to speed up the analysis processes if I want to do this later on and just say okay and now you could check this calculating the amount of solar radiation that will hit this form here. One important issue and one important factor to understand is how this is calculated. A lot of different energy analysis program are doing these types of analysis. One great thing here which also applies for ASARI is that this is really connected to the physical context of the building and the way that it does that is by a shading mask which is really defined by a dome on the sun path and to show how this sun path is working I can mark out an element here and I'm going to calculate and say sun path diagram and here I can now say update shading just takes a bit of while here so now I'm actually able to see the shading mask here. The shading mask is here but these round lines here and the way that this is working I can show you by going to shown visualized page and now we're actually able to see the stone surrounding the buildings here so the shading mask is really all the points that will define trace lines to the geometry and trace the shading conditions for the new involvement here so that's really the way to go about it and I hope you enjoyed this video. Thank you.
