Indoor humidity levels of houses in Pacific coastal climate
9th International Conference on Indoor Air Quality, Ventilation & Energy Conservation (IAQVEC), October 23-26, 2016, Songdo, South Korea. This project studied the relative humidity and indoor temperature variations in three houses in the pacific coastal climates. The houses have been monitored for one month in each four different seasons under different size of occupants, temperature variation and living conditions. These three houses represent different air tightness, number of occupants and floor size. The temperature and RH data loggers are used in every room in each house to better understand which rooms in a certain living conditions are more susceptible to moisture related problems. In addition, three existing models (European Indoor Class Model, ASHRAE 160P simple and intermediate models) are used to generate the indoor humidity level and the calculated values are compared to the measured field data., Conference paper, Published.

Integrated life-cycle design of building enclosures
In spite of the progress in developing methods and tools to support sustainable building design, there is still a lack of a formal approach to bridge the "no man’s land” gap between the traditional building engineering disciplines, and between these and the architecture, to achieve the level of building integration required for sustainability. This paper presents an integration framework that aims at facilitating the inclusion of life-cycle considerations in the design process from the outset, so that materials and systems are selected not only from environmentally friendly resources, but most importantly, to match service life performance expectations. The framework describes an iterative methodology to evaluate these expectations in practice, which is based on an understanding and modeling of the dynamics of the built environment to which materials, components, and systems are exposed. Quantitative methods and test protocols can be incorporated into the framework for assessing function-performance aspects of alternative solutions. Due to its complexity stemming from its inherent exposure to variable environmental loads and its multi-functionality, the framework focuses on addressing the life cycle of the building enclosure system. It is expected that the organization of the underlying principles of building life-cycle performance described in this paper will become a knowledge core that will facilitate a more integrated treatment of buildings in research, education, and practice., Peer reviewed, Peer reviewed article, Received 29 October 2010 ; Revised 13 January 2011 ; Accepted 18 January 2011 ; Available online 27 January 2011., Life-cycle, Service life, Building science, Building enclosure, Building integration

Interaction with an edu-game
We present the results of a study that explored the emotions experienced by students during interaction with an educational game for math (Heroes of Math Island). Starting from emotion frameworks in affective computing and education, we considered a larger set of emotions than in related research. For emotion labeling, we started from a standard methodology that relies on trained judges to report emotions over 20-s intervals, however, we asked judges to report all observed emotions in each interval, as opposed to only choosing one, as is standard practice. This variation allows us to discuss the appropriateness of this interval for emotion labeling. We present a detailed analysis of interrater reliability, both aggregated and over individual students, that considers not only labeling agreement among judges in terms of emotion type, but also with respect to the number of emotions detected. We also provide an analysis based on in-depth one-to-one interviews with judges, to gain insights on the challenges they encountered in labeling emotions., Peer reviewed, Peer reviewed article, First Online: 07 January 2016., Learning, Educational games, Emotion labeling, Interrater agreement, Interviewing judges, Affective states

Investigation of the moisture buffering potential of magnesium oxide board
Research report submitted to Peter Francis, President, MAGO Building Products Ltd in April 2016. Passive humidity control in buildings can be achieved by incorporating materials with moisture buffering potential in that these materials absorb moisture at peak times and give off the stored up moisture at low moisture production times thereby stabilizing the interior relative humidity. Some of the advantages of this phenomenon include but are not limited to energy savings, improvement of thermal comfort and perceived air quality. As such, it is necessary to investigate different materials for their moisture buffering capabilities. As part of product development, the moisture buffering characteristics of Magnesium oxide board (Magnesia board) is experimentally investigated. Other considerations such as the impact of surface finishing and ventilation are also assessed. The experiment is done by monitoring twin buildings termed the Whole Building Performance Research Laboratory (WBPRL) while measuring the relative humidity evolution in time. One is set as the reference building and finished with gypsum wallboard owing to its wide industry use. The other is set as the reference building and covered with the Magnesia board. Both buildings are first validated under non-hygroscopic conditions to ensure similar hygrothermal loading and operation of both buildings. Next, four tests are conducted to simulate surface treatments, ventilation effects, and occupancy density. For each test run, four cases are created for different surface treatment configurations. From the test, it is found that magnesia board and gypsum demonstrate similar moisture buffering characteristics. In the as-in service case where the gypsum wallboard is painted with latex paint, as it is the current common practice, and magnesia board with the company specified paint, the later demonstrates slightly better moisture buffering due to the high permeability surface treatment., Research report, Published.
Iterated belief change
Proceedings of the International Joint Conference on Artificial Intelligence (IJCAI-05) in Edinburgh, Scotland, 2005. We use a transition system approach to reason about the evolution of an agent’s beliefs as actions are executed. Some actions cause an agent to perform belief revision and some actions cause an agent to perform belief update, but the interaction between revision and update can be nonelementary. We present a set of basic postulates describing the interaction of revision and update, and we introduce a new belief evolution operator that gives a plausible interpretation to alternating sequences of revisions and updates., Conference paper, Published.
