Understanding the dynamic hygrothermal behavior of building elements is very important to ensure the optimal performance of buildings. The Laboratory for Quality Control in Buildings of the Basque Government tested a flat roof designed by a construction company that developed a building to be constructed using prefabricated modules. This is a five to eight floor building with ventilated façade and a flat roof covered by gravel with the possibility of changing it to a green cover. The paper aims to discuss this issue.

The interest of this research was threefold. The first objective was to accurately test, under real dynamic weather conditions, the roof design in a PASLINK test cell to obtain the U-value and the thermal capacitance of the different roof layers, and of the roof as a whole, through the precise calibration of resistance-capacitance mathematical models of the roof. Based on the parameters and experimental information of these calibrated models, a second goal was to calibrate and validate a Wufi model of the roof.

This second calibrated model was then used to simulate the dynamic hygrothermal behavior of the roof, obtaining the roof’s hourly thermal demand per square meter for a whole year in different locations considered in the Spanish Building Code. These simulations also permitted the authors to study the risk of condensation and mold growth of the tested component under different climatic conditions.

The successful combination of the PASLINK method to calibrate the Wufi hygrothermal model is the main novelty of this research.

The purpose of this paper is the analysis of a methodology for the buildings' intelligence assessment through the development of a matrix tool. Techniques and technologies for use in designing, constructing and operating intelligent buildings are well known or available on the market and many intelligent buildings have been built. However, just how intelligent these buildings actually are in comparison to conventional buildings is often a question. Due to the lack of commonly accepted methods and pertinent supporting data, the assessment of the overall performance of intelligent buildings cannot be carried out. It remains difficult, if not impossible, to carry out a fair comparison between different buildings in term of intelligence. As a result, the construction industry proceeds without adequate knowledge about the best practice in intelligent building.

For the purpose of the present assessment, the definition of an intelligent building has been reviewed and refined. Based on the adopted definition, a matrix tool is developed. The objective of this tool is to provide facilities managers with an effective methodology for improving the energy and indoor environmental performance of their building stock. With appropriate development, the methodology could also form the basis of voluntary or regulatory methodology for building intelligence accreditation.

The paper describes the matrix tool's global performance indicators and specific performance indicators for the intelligent buildings' assessment. Moreover the application of the matrix tool in assessing two buildings is described.

The paper encourages a deeper analysis of the buildings' intelligence providing the initial framework.

The present paper proposes an innovative methodology for intelligent buildings assessment.
