International Building Physics Conference 2018
In order to evaluate the impacts of volatile organic compounds (VOCs) emissions from building materials on the indoor pollution load and indoor air quality beyond the standard chamber test conditions and test period, mechanistic emission source models have been developed in the past. However, very limited data are available for the required model parameters including the initial concentration (Cm0), in-material diffusion coefficient (Dm), partition coefficient (Kma), and convective mass transfer coefficient (km). In this study, a procedure is developed for estimating the model parameters by using VOC emission data from standard small chamber tests. Multivariate regression analysis on the experimental …

Evaluation Of The Physical Interpretability Of Calibrated Building Model Parameters, Sarah Juricic, Simon Rouchier, Aurélie Foucquier, Gilles Fraisse
International Building Physics Conference 2018
Identifying building envelope thermal properties from the calibration of a lumped model raises identifiability issues. Not only needs the simplified model to be structurally identifiable, i.e. deliver unique estimates after calibration, but also the data used might not be informative enough to result in either or both accurate estimates and physically interpretable values. This could particularly be the case when data is extracted from non intrusive in situ measurements, in the sense not disturbing potential occupancy. In this frame, this paper develops a method to investigate the physical interpretation of the parameters of lumped models through a numerical tests procedure. …

Considerations On The Thermal Modelling Of Insulated Metal Panel Systems, Ligia Moga, Ioan Moga
International Building Physics Conference 2018
The very strict regulations imposed by the European directives regarding low energy consumptions of buildings imposes the availability of thermal and energy efficient solutions for the building envelope. One common solution is given by insulated metal penal systems, which are typically used for industrial buildings but lately also used for other types of buildings (e.g. residential buildings, hotels, hospitals). These types of solutions must be properly addressed from the thermal modelling and simulation point of view considering a different thermal behaviour due to its detail components. For insulated metal penal systems the typical calculations are done by considering only the …

Dynamic Environment, Adaptive Comfort, And Cognitive Performance, Richard De Dear, Fan Zhang
International Building Physics Conference 2018
Since the invention of airconditioning over 100 years ago a central research challenge has been to define the indoor environmental temperatures best suited for occupants. The first scientific approach to this question was framed in terms of optimising occupant thermal comfort, commonly expressed as a U-function, symmetrical around a single optimum temperature for any given combination of the remaining comfort parameters (ISO, 2005). The inescapable conclusion drawn from such logic in the minds of risk-averse design engineers is that the only strategy able to reliably deliver occupant comfort is HVAC applied to sealed-façade architecture. A rigorous scientific rebuttal of the …

Hygrothermal Performance Of Historic Massive Wall: When Is 2d Simulation Necessary?, Dario Bottino Leone, Marco Larcher, Alexandra Troi, John Grunewald
International Building Physics Conference 2018
Hygrothermal analysis of historical building envelopes is crucial in ensuring their durability and enhancing their performances. The use of hygrothermal dynamic simulation is the most effective approach to predict moisture related damages or risk of mould growth on ancient masonry envelopes. However, simulating the hygrothermal behaviour of a historic wall composed by stones or bricks and mortar joints, with a detailed two-dimensional (2D) model, is typically a complex and time-consuming process. For this reason, in numerical models, composite walls are often simplified with a one-dimensional (1D) layer, neglecting the mortar joints. An oversimplified numerical model could affect the evaluation of …

Simulation Of Building Physics For Beginning Design Students, Alexander Timmer
International Building Physics Conference 2018
Concepts such as heat transfer, stack effect, natural ventilation, and other problems related to building physics are taught to beginning design students through architectural examples, deterministic diagrams, and rules of thumb. Unlike the approach to teaching form, which involves exploration and iteration within a studio environment, often suspending disbelief to allow exploration, these exercises see architecture through the lenses of optimization, equilibrium, and objective outcomes. They are taught as steady state concepts. Instead of leaning on teaching techniques derived from an engineering standpoint, often technocratic and deterministic, it would serve beginning design students well to explore these concepts through experimentation …
