In the development of the applications described in NCL language, it was noticed the reusing for some document models and structures, enabling repetitions for common codes in the applications.Thus, due to the need to generalize the development of applications described in the NCL language was created the Luar templates processing system. The Luar system has a templates processor developed with the Lua language and a library to keep and aggregate the collection of templates, sharing them between the developers.This paper has as goal to present the evaluation of the Luar system through software engineering experimental techniques. Language NCL and Lua courses were taught for undergraduate students group and compared the development time of two applications utilizing the different languages. The result showed that development with the Luar language is more productive than the development purely with NCL. It having the development time economy of 60% to 78% approximately, depending on the kind of application, compared with the authored with NCL.
