Engineering Daylight into Commercial Buildings

Integrating Commercial Process Simulators into Engineering Courses

This paper presents a didactic activity concerning the use of PI/PID tuning rules, also addressing the issue of how to achieve a knowledgeable selection of the most suited one for the particular problem at hand. The activity aims at making the students aware of the rationale of said rules, and therefore of their suitability for the dynamic (not necessarily physical) characteristics of the contr...

Solar Heating in Commercial Buildings

Multispectral synthesis of daylight using a commercial digital CCD camera.

Performance of multispectral devices in recovering spectral data has been intensively investigated in some applications, as in spectral characterization of art paintings, but has received little attention in the context of spectral characterization of natural illumination. This study investigated the quality of the spectral estimation of daylight-type illuminants using a commercial digital CCD ...

Benchmarking the energy efficiency of commercial buildings

Benchmarking energy-efficiency is an important tool to promote the efficient use of energy in commercial buildings. Benchmarking models are mostly constructed in a simple benchmark table (percentile table) of energy use, which is normalized with floor area and temperature. This paper describes a benchmarking process for energy efficiency by means of multiple regression analysis, where the relat...
