Fig.1: Annual air and ground temperatures (daily averages)A building exchanges heat not only with the outside air but also with the ground. The ground temperature depends on the location and the depth. At six meters under and deeper, the temperature re…
Two time series and their cross-correlation functionsIn a previous post, I showed you what autocorrelation function (ACF) is and how it can be used to detect temporal patterns in student data. The ACF is the correlation of a signal with itself. We are …
Cormac Paterson, a 17-years old student from Arlington High School in Massachusetts, has created yet another set of beautiful architectural designs using our Energy3D CAD software. The variety of his designs can be used to gauge the versatility of the …
Technology allows us to record almost everything happening in the classroom. The fact that students’ interactions with learning environments can be logged in every detail raises the interesting question about whether or not there is any significant meaning and value in those data and how we can make use of them to help students and […]
The National Science Foundation funds SmartCAD—an intelligent learning system for engineering design
We are pleased to announce that the National Science Foundation has awarded the Concord Consortium, Purdue University, and the University of Virginia a $3 million, four-year collaborative project to conduct research and development on SmartCAD, an intelligent learning system that informs engineering design of students with automatic feedback generated using computational analysis of their work. […]
An array of heliostats in Energy2D (online simulation)A new class of objects was added in Energy2D to model what is called a heliostat, a device that can automatically turn a mirror to reflect sunlight to a target no matter where the sun is in the sky….
Figure 1. A stock-and-flow model of building energy. Our Energy3D CAD software has two built-in simulation engines for performing solar energy analysis and building thermal analysis. I have extensively blogged about solar energy analysis using Energy3D. This article introduces building thermal analysis with Energy3D. Figure 2. A colonial house. The current version of the building […]
Many users asked if there is any good tutorial of Energy2D. I apologize for the lack of a User Manual and other tutorial materials (I am just too busy to set aside time for writing up some good documentations).So Carmen Trudell, an architect who curren…
Energy3D supports the design of some basic architectural styles commonly seen in New England, such as Colonial and Cape Cod. Its simple 3D user interface allows users to quickly sketch up a house with an aesthetically pleasing look — with only mouse c…
The behavior of a house losing or gaining thermal energy from the outside in a 24-hour cycle, when visualized using Energy3D’s heat flux view, resembles breathing, especially in the transition between seasons in which the midday can be hot and the midn…
