“…23, 24 These programs are especially valuable because they can calculate the airflow and relative pressures between different building zones and AER values. 25, 26 They have been used for indoor air quality, including radon intrusion studies. 27 Recently multizone programs have been improved by coupling with CFD programs to combine the effect of indoor and outdoor air quality on pressure gradients and air flow rate distribution in a building.…”

Vapor intrusion exposure risks are difficult to characterize due to the role of atmospheric, building and subsurface processes. This study presents a three-dimensional VI model that extends the common subsurface fate and transport equations to incorporate wind and stack effects on indoor air pressure, building air exchange rate (AER) and indoor contaminant concentration to improve VI exposure risk estimates. The model incorporates three modeling programs: 1) COMSOL Multiphysics to model subsurface fate and transport processes, 2) CFD0 to model atmospheric air flow around the building, and 3) CONTAM to model indoor air quality. The combined VI model predicts AER values, zonal indoor air pressures and zonal indoor air contaminant concentrations as a function of wind speed, wind direction and outdoor and indoor temperature. Steady state modeling results for a single-story building with a basement demonstrate that wind speed, wind direction and opening locations in a building play important roles in changing the AER, indoor air pressure, and indoor air contaminant concentration. Calculated indoor air pressures ranged from approximately −10Pa to +4Pa depending on weather conditions and building characteristics. AER values, mass entry rates and indoor air concentrations vary depending on weather conditions and building characteristics. The presented modeling approach can be used to investigate the relationship between building features, AER, building pressures, soil gas concentrations, indoor air concentrations and VI exposure risks.

“…Over the past decades, computer-aided simulation of buildings has become widely available; hence these days, it is used both in research and in industry [7]. Loonen et al [8], analysed the factors that affect the success and failure of innovations in construction industry and demonstrated the potential of using whole-building performance simulation in the domain of research and development.…”

“…A model is often mathematical and describes the system that is to be simulated at a certain level of abstraction. Within a BPS program descriptions of the construction, occupancy patterns and HVAC systems are given and a mathematical model is constructed to represent the possible energy flow-path and their interactions [7,11]. Many assumptions, approximations and compromises are inevitably made on the mathematical formulations describing the physical laws within the model [40].…”

“…The use of simulation tools in general and lighting simulation tools, in particular, have been growing over the recent years [1][2][3][4][5], which led to an improved quality of lighting analysis by providing quantitative and qualitative outputs. Photometric data or performance metrics are the main types of quantitative outputs; rendered images and data visualization that help the interpretation of the results are examples of the qualitative output type [6].…”

“…(p. 3) Interest in EBD has been growing extensively since Ulrich's publication [16] addressed the effect of views of nature on patients [17]. In the building industry, EBD has been applied mainly to the design of healthcare facilities, even though, due to the flexibility of this method, it can be adopted by other types of buildings such as offices, schools, sports facilities, and so forth [18,19].…”

A Conceptual Framework for Integration of Evidence-Based Design with Lighting Simulation Tools

Abstract:The use of lighting simulation tools has been growing over the past years which has improved lighting analysis. While computer simulations have proven to be a viable tool for analyzing lighting in physical environments, they have difficulty in assessing the effects of light on occupant's perception. Evidence-based design (EBD) is a design method that is gaining traction in building design due to its strength in providing means to assess the effects of built environments on humans. The aim of this study was to develop a conceptual framework for integrating EBD with lighting simulation tools. Based on a literature review, it was investigated how EBD and lighting simulation can be combined to provide a holistic lighting performance evaluation method. The results show that they can mutually benefit from each other. EBD makes it possible to evaluate and/or improve performance metrics by utilizing user feedback. On the other hand, performance metrics can be used for a better description of evidence, and to analyze the effects of lighting with more details. The results also show that EBD can be used to evaluate light simulations to better understand when and how they should be performed. A framework is presented for integration of lighting simulation and EBD.
