    This paper describes the use of transient building performance simulation in order to develop design guidelines for educational buildings in Turkiye. The premise of the work is that design decisions taken during early stages of the building process have a large impact on the performance of the resulting building and hence need solid underpinning. Yet straightforward application of building performance in these early stages has proven to be difficult. Hence this paper applies sensitivity analysis to the outcomes of simulations carried out with the ESP-r simulation program in order to identify the most relevant parameters in school design. This allows building designers to make informed decisions, without having to revert to modelling and simulation. The research described in this paper is part of an ongoing project of preparing a design guideline for Turkish building designers who intend to design with climate

    An exploration of the option space in student design projects for uncertainty and sensitivity analysis with performance simulation

    Get PDF
    This paper describes research conducted to gather empirical evidence on extent, character and content of the option space in building design projects, from the perspective of a climate engineer using building performance simulation for concept evaluation. The goal is to support uncertainty analysis and sensitivity analysis integrated to building performance simulation (BPS) tools. The integration will need to assist design rather than automate design, allowing a spontaneous, creative and flexible process that acknowledges the expertise of the design team members. The paper investigates the emergent option space and its inherent uncertainties of an artificial setting (student design studios). The preliminary findings provide empirical evidence of the high variability of the option space that can be subjected to uncertainty analysis and sensitivity analysis

    This paper describes the results of a computational study on the feasibility of cooling houses in the Netherlands with a system consisting of a heat exchanger in the soil, a heat pump, and a low temperature heating system. The study is based on simulation of the building using the transient thermal simulation tool VA114, simulation of the thermal storage system using the dedicated Earth Energy Designer (EED) program, and simulation of the indoor air flow using the CFD-tool WISH3D. The results indicate that cooling with such a system is indeed feasible in the Netherlands, if care is taken of the limitation in specific cooling power to prevent condensation. Using constant temperature control, the temperature difference between water and air is limited to 5 K, resulting in a specific cooling power of 12 W/m2. Other passive measures, like solar shading and night ventilation therefore are also required. With this peak load limitation the capacity of the thermal storage system for cooling is sufficient when it is designed for heating only

    An investigation of the option space in conceptual building design for advanced building simulation

    This article describes research conducted to gather empirical evidence on size, character and content of the option space in building design projects. This option space is the key starting point for the work of any climate engineer using building performance simulation who is supporting the design process. The underlying goal is to strengthen the role of advanced computing in building design, especially in the early conceptual stage, through a better integration of building performance simulation tools augmented with uncertainty analysis and sensitivity analysis. Better integration will need to assist design rather than automate design, allowing a spontaneous, creative and flexible process that acknowledges the expertise of the design team members. This research investigates and contrasts emergent option spaces and their inherent uncertainties in an artificial setting (student design studios) and in real-life scenarios (commercial design project case studies). The findings provide empirical evidence of the high variability of the option space that can be subjected to uncertainty analysis and sensitivity analysis

    On selecting weather data sets to estimate a building design's robustness to climate variations

    The integration of techniques for uncertainty and sensitivity analysis in building performance simulation (BPS) has a number of potential benefits related to design. It allows assessing the accuracy of performance predictions; it can be used to provide concept specific design guidance, and it enables a robustness assessment of the design proposal to different future climate scenarios. The later is considered here. The problems associated with using climate data sets as input to sampling based uncertainty and sensitivity analysis techniques are; (1) these represent time series data with history, and (2) when used as reference data sets, are purpose bound. To address the problems a typical office room is exposed to measured historic weather files, projected future weather data and a derived artificial reference weather data set representative for the period and location. Its response is compared using peak cooling load as criterion for the buildings robustness. It is found that the individual artificial reference data sets are not suited to predict the peak cooling load and its uncertainty band, as they were created for the prediction of a specific performance metrics and for specific building types. However scenario based multi-year future weather data sets show the potential to be successfully used with sampling based uncertainty and sensitivity analysis techniques

    Development of a thermally robust school outline design for the different climate regions of Turkiye

    This paper presents the development of a novel school outline design, which can be applied in the different climate zones of Turkiye, underpinned by building performance simulation. The work builds on an earlier study, presented at the Building Simulation 2007 conference, which analysed the sensitivity of an existing scheme that had indeed been applied in all different climate zones, with different degrees of success. This follow-on project goes one step further and attempts to develop a new, more thermally robust school outline design. The underlying research bases itself on building performance simulation, using the ESP-r simulation engine and applying global sensitivity analysis (Monte Carlo Method) to assess the robustness of different design variants in a large, multidimensional option space of outline design parameters. The outcome of the study is an outline design concept called Modulsco that is significantly more robust than the current general scheme. Overall, this paper demonstrates how building simulation can contribute to the pre-design of better (school) buildings. It is hoped that the scheme will help make these future buildings more comfortable and more energy efficient
