genetic algorithm based approach to optimize building Envelope Design for residential buildings
Building and Environment, 2010Co-Authors: Daniel Tuhusdubrow, Moncef KrartiAbstract:Abstract A simulation–optimization tool is developed and applied to optimize building shape and building Envelope features. The simulation–optimization tool couples a genetic algorithm to a building energy simulation engine to select optimal values of a comprehensive list of parameters associated with the Envelope to minimize energy use for residential buildings. Different building shapes were investigated as part of the Envelope optimization, including rectangle, L, T, cross, U, H, and trapezoid. Moreover, building Envelope features were considered in the optimization analysis including wall and roof constructions, foundation types, insulation levels, and window types and areas. The results of the optimization indicate rectangular and trapezoidal shaped buildings consistently have the best performance (lowest life-cycle cost) across five different climates. It was also found that rectangle and trapezoid exhibit the least variability from best to worst within the shape.

a review on optimization methods applied in energy efficient building geometry and Envelope Design
Renewable & Sustainable Energy Reviews, 2018Co-Authors: Farshad KheiriAbstract:Abstract Building Envelope parameters and geometric configurations can considerably influence the building energy performance. However, determining the best trade-offs of different building shape and Envelope configurations to yield near-optimal Design alternatives with respect to their energy performance is not a straight-forward task. Consequently, different methods have been utilized to optimize building Envelope parameters and geometric configurations to achieve better energy performance. The objective of this paper is to provide an extensive review of the optimization methods and their application in energy-efficient architectural building Design to better identify the potentials and applicability of different optimization methods. This paper reviews the optimization research, where building Envelope parameters and geometric configurations are considered remarkably as the optimization independent variable(s) and building energy consumption/demand is included as an objective in the optimization process. The associated derivative-free and derivative-based optimization methods and their application in energy-efficient building Design are included in this review. In addition, decision-making approaches are discussed for multi-objective optimizations. Current optimization tools are demonstrated. Finally, crucial considerations, including limitations and suggestions for the related future studies are concluded.

The role of integrated performance model in sustainable Envelope Design and assessment
International Journal of Sustainable Engineering, 2014Co-Authors: Joseph Iwaro, Abrahams Mwasha, Rupert G. Williams, William WilsonAbstract:The issue of sustainable Design and assessment of the residential building Envelope is a complex process that requires considering many factors including life cycle performance. As such, in an effort to develop an integrated approach that combines relevant sustainable development factors and life cycle concepts for sustainable Designs, an integrated performance model (IPM) was developed. The IPM is an essential tool to aid the sustainable Design of the residential building Envelope, reduce the carbon emission and the whole residential building energy consumption, thereby ensuring sustainable performance of the building Envelope and building sustainability. The IPM application indicates that sustainable performance of the building Envelope in extreme weather and climatic condition is significantly influenced by the energy efficiency performance of the development.

Original Article/Research The impact of sustainable building Envelope Design on building sustainability using Integrated Performance Model
2014Co-Authors: Joseph Iwaro, Abrahams MwashaAbstract:Sustainable Design is a Design approach put in place to promote the environmental quality and the quality of building indoor environment by reducing negative impacts on building and the natural environment. Also, it is a Design philosophy that seeks to incorporate sustainable development concept in terms of initiatives and values into sustainable building Envelope Design. However, the problem remains as to what constitutes sustainable development concept required for sustainable Envelope Design. Therefore, this paper is aimed at examining the role of sustainable development concept in sustainable Envelope Design by investigating the impacts of sustainable Envelope Design on building sustainability using Integrated Performance Model. This was validated by comparing the energy efficiency performance from selected case studies of buildings with sustainable development concept and building Envelope without sustainable development concept. It is expected that the incorporation of sustainable development concept in terms of initiatives and values will enhance the energy performance of building envelopment development and bring about building sustainability. 2014 The Gulf Organisation for Research and Development.

an integrated criteria weighting framework for the sustainable performance assessment and Design of building Envelope
Renewable & Sustainable Energy Reviews, 2014Co-Authors: Joseph Iwaro, Abrahams Mwasha, Rupert G. Williams, Ricardo ZicoAbstract:Weighting and selection of criteria for the sustainable performance assessment of building Envelope are onerous process for building Designers, since the process needs to be carefully undertaken in order to adequately assess the sustainable performance of the building Envelope. However, the process of selecting performance criteria and weighting the importance of these criteria for the assessment of the building Envelope sustainable performance is both challenging and technically complex. A lot of multi-criteria aggregating methods have been developed, many of which require appropriate criteria and weights to evaluate sustainable performance. Some of these methods lack quantitative weighting mechanism while some lack subjective weighting mechanism. Since the weight plays a major role in ranking, assessing and selection of the sustainable Envelope Design, this paper presents an Integrated Criteria Weighting Framework incorporated into an Integrated Performance Model (IPM) for determining integrated weight for criteria involve in assessing the sustainable performance and selecting a sustainable Envelope Design. On the basis of the numerical findings, this study concludes that the proposed framework can successfully address the problem of criteria weighting and assessing the building Envelope sustainable performance towards achieving building sustainability.

Envelope Design optimization by thermal modelling of a building in a warm climate
Energies, 2017Co-Authors: Cristina Baglivo, Paolo Maria Congedo, Matteo Di Cataldo, Luigi Damiano Coluccia, Delia DagostinoAbstract:Finding the most appropriate configuration of building components at the Design stage can reduce energy consumption in new buildings. This study aims to optimize the Design of the Envelope of a new residential building located in a warm climate (southern Italy). The thermal behaviour of the building has been analysed to evaluate the indoor operative air temperature for several configurations. The building prototype has been modelled using the dynamic simulation software TRNSYS 17 (A transient system simulation program, University of Wisconsin, Solar Energy Laboratory, USA, 2010) using a sequential search technique. Starting from the simplest building configuration, the main evaluated components are: walls, slab-on-ground floor, roof, shading, windows and internal heat loads. For each of these components, different Design options have been modelled and compared in terms of indoor thermal comfort. Comfort parameters have also been taken into account to evaluate users’ satisfaction with the optimized configurations. The study of the operative air temperature demonstrates that the absence of insulating layers in the ground floor ensures a lower internal temperature in summer. The paper shows how each component impacts the thermal behaviour of the whole building. It highlights the usefulness of the Envelope Design optimization that is characterized by high values of heat storage capacity, enabling internal temperature fluctuations to be kept under control, especially during summer.
