This objective can be reached using two different and complementary approaches-measurements and simulations. Worldwide energy reduction will then benefit from the improvement of energy efficiency in buildings. Although both methods require high expertise from operators and showed good results in terms of accuracy, automatic calibration presents better performance and consistently helps with speeding up the procedure. Differences, advantages and disadvantages are evidenced applying both methods to a dynamic simulation model of a real office building in Rome, Italy. This paper aims to compare a manual calibration procedure with an automatic calibration method developed by the authors, coupling dynamic simulation, sensitivity analysis and automatic optimization using IDA ICE, Matlab and GenOpt respectively. Automatic calibration relies on mathematical and statistical methods that mostly use optimization algorithms to minimize the difference between measured and simulated data. Manual calibration consists of an iterative trial and error procedure that requires high skill and expertise of the modeler. Two approaches can be adopted-manual or automatic. High modelling accuracy can be achieved only through calibration. For this purpose, simulation models can be used both as diagnostic and prognostic tools, reproducing the behaviour of the real building as accurately as possible. So, while there are still situations where manual testing is unavoidable, automated testing is what more testers are choosing to deal with large volumes of tasks and to detect as many bugs as possible.Energy reduction can benefit from the improvement of energy efficiency in buildings. The possibilities of automated testing are now really big and growing, but sometimes there are situations where automated testing programs find bugs that don’t exist, and then the testers have even more work to do trying to figure out whether the bug they found is correct or not. Sometimes the testing process is so complex that different scenarios need to be tested and changed during the process. This can only be done by doing everything yourself from the beginning to the end of the testing process. There are times when a tester needs to know the whole testing process and pay attention to the smallest details. With a higher testing volume, you can be more productive! Unlike manual testing, automated testing allows you to test an entire app, device, or software at once. Automated testing allows for better results because it can detect more bugs per test. Scripts are written with programming languages such as JAVA or Python, and most importantly, they can be used more than once. However, automated testing also requires manual work (the tester has to create the basis for the test scenario), but it is incomparably less. Anyone who has ever done manual testing knows how much repetitive work is involved. And this problem is becoming more and more acute as the volume of work requiring testing in IT grows at a tremendous rate. Automated testing was developed primarily to solve the problem of manual testing – lack of time. This is why choosing automated testing increases productivity. This is by far the biggest advantage of automated testing over manual testing. There are many advantages to automated testing In automated testing, testers have to write scripts that run the tests automatically.Īutomation testing involves testers writing test scripts that run tests automatically. Manual testing requires analysts and engineers to be heavily involved in the various stages of the development and launch of the product under test. The biggest difference between manual and automation testing is who executes the test case. We will discuss the differences between these two types of testing in this post. Websites and mobile apps should work flawlessly, which is why testing is an inevitable part of a developer’s routine.
