Energy consumption data, in particular those involving public buildings, are impacted by many factors: the building structure, climate/environmental parameters, construction, system operating condition, and user behavior patterns. Traditional methods for data analysis are insufficient. This paper delves into the data mining technology to determine its application in the analysis of building ene...

This paper examines the use and accuracy of a moisture probe used in the walls of a straw-bale building. The performance of the moisture probe is assessed against laboratory based measurements. The measurements from a number of moisture probes placed in the walls of a case study straw-bale building over a two-year period are presented. The moisture content measurements from the building are dis...

pavement materials have great impact on heat island control under the urban canyon layer. understanding the properties of pavement materials can help to reduce the heat island effect. introducing the main properties of pavement surfaces affecting sol-air temperature and mean radiant temperature - such as albedo, permeability, conductivity, thickness, emissivity, irradiation and convective air f...

Building a self-gravitating hydrodynamic code as a combination of a hydrodynamic solver and a gravity solver is discussed. We show that straightforward combining those two solvers generally leads to a code that does not conserve energy locally, and instead a special Consistency Condition ought to be satisfied. A particular example of combining Softened Lagrangian Hydrodynamics (SLH) with a PM g...

Passive and active solar heating systems have drawn much attention and are widely used in residence buildings in the Qinghai-Tibetan plateau due to its high radiation intensity. In fact, there is still lack of quantitative evaluation of the passive and active heating effect, especially for residential building in the Qinghai-Tibetan plateau areas. In this study, three kinds of heating strategie...

A comparison of the performance of two fault detection and diagnosis methods applied to a cooling coil subsystem in an air-handling unit installed in a real building is presented. Both methods employ a first principles based reference model of the target system. One scheme carries out diagnosis using expert rules and the other recursively re-estimates selected parameters of the system model tha...

building contraventions have become one of the important dilemmas of many cities like tehran. the wide aftereffects of the contraventions and the large cost of removing their negative effects, make the reduction of the possibility of their occurrence essential. this paper tries to find the reasons and roots of building contraventions in order to prevent their occurrence through appropriate plan...
