The review of the design and construction details of the external wall assembly of a 122 m (400 ft) tall building in a Canadian city is presented. Inadequate tolerance consideration for the steel frame structure and elements of the building envelope and changes in the fireproofing method led to a series of changes and conflicts, delay in the project, and added costs. This case study is presented to show the need to adopt integrated building design principles from the conceptual stage to achieve compatibility between building subsystems while they are being assembled and during the life of the building and to accelerate the construction process.

Users’ satisfaction on quality is a key that leads successful completion of the project in relation to decision-making issues in building design solutions. This study proposed QFD (quality function deployment) based benchmarking logic of market products for building envelope solutions. Benchmarking logic is composed of QFD-TOPSIS and QFD-SI. QFD-TOPSIS assessment model is able to evaluate users’ preferences on building envelope solutions that are distributed in the market and may allow quick achievement of knowledge. TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) provides performance improvement criteria that help defining users’ target performance criteria. SI (Suitability Index) allows analysis on suitability of the building envelope solution based on users’ required performance criteria. In Stage 1 of the case study, QFD-TOPSIS was used to benchmark the performance criteria of market envelope products. In Stage 2, a QFD-SI assessment was performed after setting user performance targets. The results of this study contribute to confirming the feasibility of QFD based benchmarking in the field of Building Envelope Performance Assessment (BEPA).

AbstrakKaidah struktur seringkali merupakan penghambat proses kreativitas arsitek dalam merancang bentuk bangunan. Banyak karya arsitektur yang hanya bermain pada kemasan saja, tanpa mempertimbangkan efisiensi struktur terutama pada rancangan gedung besar, baik gedung tinggi, maupun bentang lebar. Umumnya gedung tinggi walaupun fungsi dan tampilannya berbeda menggunakan struktur yang sama, yaitu struktur inti dan rangka (core and frames), yang dibedakan dari bentuk (aditif, substraktif, rotasi, repetisi), warna, jenis material, sehingga ketidakteraturan struktur disembunyikan demi mengejar bentuk bangunannya. Hal ini dikarenakan transformasi bentuk sebagai langkah eksplorasi arsitek dalam mewujudkan desainnya tidak menyertakan pertimbangan estetika struktur sebagai bagian dari proses kreatifnya. Pendekatan struktur masih terkesan penuh dengan rumus dan angka yang dianggap akan menghambat proses kreatif dalam olahan bentuk dan ruang. Oleh karenanya tidak sedikit rancangan yang memanipulasi bentuk luarnya dengan konstruksi tambahan, yang cenderung ornamental. Arsitek umumnya menghindar menampilkan struktur sebagai bagian dari estetika,  padahal analisis struktur merupakan proses yang harus dilalui dalam konsep perancangan demi terbangunnya sebuah rancangan gedung. Kajian ini adalah suatu model pendekatan struktur pada gedung tinggi dengan mengikuti tahapan dasar dalam proses analisis struktur. Diharapkan kajian ini dapat memberikan gambaran pendekatan kualitatif pada konsep struktur dan diterapkan dalam proses penyusunan konsep perancangan arsitektur sehingga dapat menghasilkan bentuk struktur yang baik.kata kunci: kaidah struktur, bangunan tinggi, kreativitas arsitek, estetika strukturAbstractRule of structure often is an inhibitor of the process of creativity of architects in designing building’s shape. Many architectural works only play on the packaging, without considering the efficiency of the structure, especially in the design of large buildings, both tall and wide-spanning buildings. Generally, tall buildings although their function and appearance are different use the same structure, namely the core and frame structure, which is distinguished from shape (additive, subtractive, rotation, repetition), color, type of material, so that structural irregularities are hidden in pursuit the building shape. This is because the transformation of form as exploration step in realizing the design architect does not include aesthetic considerations structures as part of the creative process. The structural approach still seems full of formulas and numbers which are considered to hinder the creative process in processing forms and spaces. Therefore many designs manipulate the outer shape with additional construction, which tends to be ornamental. Architects generally avoid presenting structures as part of aesthetics, whereas structural analysis is a process that must be passed in the design concept in order to construct a building design. This study is a structural approach model in tall buildings by following the basic step in the structural analysis process. It is hoped that this study can provide an overview of qualitative approach in structural concepts and could be applied in the process of architectural design concepts so that it could produce the right structural design.key words: rules of structure, tall building, architect creativity, aesthetic structures

Abstract From 2016 until 2019, the Circular Retrofit Lab (CRL) was realised within the H2020-funded project Building As Material Banks (BAMB). The CRL was an experimental pilot project concerning the refurbishment of eight student housing modules in Brussels, Belgium. The lab aims to demonstrate how to implement circular building design in a retrofitting project. This paper discusses the design choices and the outcome of the CRL’s building envelope. That envelope consists of a modular façade system of prefabricated panels. The innovative, adaptable and reusable building solutions applied in the CRL have been developed in collaboration with various construction stakeholders and included, exceptionally in the design and construction process, also industrial partners. In this study, we go deeper into the impact of the multi-disciplinary approach on the resulting implementation of a circular building envelope. Through a reflexive learning-history workshop, we can show how the involvement of various actors and unconventional circularity requirements increase the complexity of the project, but also how they positively impact the reactivation of existing buildings and proved to be a lasting learning opportunity to all partners involved.

The built environment remains a strategic research and innovation domain in view of the goal of full decarbonization. The priority is the retrofitting of existing buildings as zero-emission to improve their energy efficiency with renewable energy technologies pulling the market with cost-effective strategies. From the first age of photovoltaics (PV) mainly integrated in solar roofs, we rapidly moved towards complete active building skins where all the architectural surfaces are photoactive (Building Integrated Photovoltaics - BIPV). This change of paradigm, where PV replaces a conventional building material, shifted the attention to relate construction choices with energy and cost effectiveness. However, systematic investigations which put into action a cross-disciplinary approach between construction, economic and energy related domains is still missing. This paper provides the detailed assessment of a real multifamily building, taking into account retrofit scenarios for making active the building skin, with the goal to identify the sensitive aspects of the energetic and economic effectiveness of BIPV design options. By assuming a real case study with monitored data, the analysis will consider a breakdown of the main individual parts composing the building envelope, by then combining alternative re-configurations in merged clusters with different energy and construction goals. Results will highlight the correlation between building skin construction strategies and the energy and cost parameters by identifying the cornerstones for enhancing efficiency. The outcomes, related to the total life cost, self-consumption/sufficiency, in combination with different building design options (façade, roof, balconies, surface orientations, etc.), provide a practical insight for researchers and professionals to identify renovation strategies by synergistically exploiting the solar active parts towards lower global costs and higher energy efficiency of the whole building system.

Purpose There are a number of decision-making problems encountered by a building design team. This issue is apparent in assessment of building envelope materials and designs in the early design stage. The purpose of this paper is to develope a decision support tool based on a quality function deployment (QFD) approach integrated with a knowledge management system (KMS) and fuzzy theory to facilitate a building design team to simultaneously mitigate the decision-making problems when assessing the building envelope materials and designs for the first instance. Design/methodology/approach This study engaged a design team comprising three decision makers (DMs) to test the developed decision support tool through a case study of a representative building project. The study employed deductive qualitative data analysis with use of a framework analysis approach to analyze perspectives of the DMs after completing the case study through a semi-structured interview. Findings A mapping diagram derived qualitatively from the framework analysis suggested that the tool can help mitigate the identified decision-making problems as a whole. Originality/value Practical contributions of using the decision support tool include achievement of a more efficient design and construction management, and higher productivity of a project. In terms of academic contributions, this study expands capabilities of a conventional decision support system, KMS, and QFD tool to handle decision-making problems.

Current approaches to the estimation of wind-induced wind effects on tall buildings are based largely on 1970s and 1980s technology, and were shown to result in some cases in errors of up to 40%. Improvements are needed in: (i) the description of direction-dependent aerodynamics; (ii) the description of the direction-dependent extreme wind climate; (iii) the estimation of inertial wind effects induced by fluctuating aerodynamic forces acting on the entire building envelope; (iv) the estimation of uncertainties inherent in the wind effects; and (v) the use of applied wind forces, calculated inertial forces, and uncertainty estimates, to obtain via influence coefficients accurate and risk-consistent estimates of wind-induced internal forces or demand-to-capacity ratios for any individual structural member. Methods used in current wind engineering practice are especially deficient when the distribution of the wind loads over the building surface and their effects at levels other than the building base are not known, as is the case when measurements are obtained by the High-Frequency Force Balance method, particularly in the presence of aerodynamic interference effects due to neighboring buildings. The paper describes a procedure that makes it possible to estimate wind-induced internal forces and demand-to-capacity ratios in any individual member by: developing aerodynamic and wind climatological data sets, as well as aerodynamic/climatological directional interaction models; significantly improving the quality of the design via rigorous structural engineering methods made possible by modern computational resources; and properly accounting for knowledge uncertainties. The paper covers estimates of wind effects required for allowable stress design, wherein knowledge uncertainties pertaining to the parameters that determine the wind loading are not considered, as well as estimates required for strength design, in which these uncertainties need to be accounted for explicitly.

The nearly Zero Energy building (nZEB) renovation market is currently the key feature in the construction sector. RenoZEB aims to develop a systematic approach for retrofitting by assembling different technologies in a plug and play building envelope. This paper presents the methodology used to transform the RenoZEB concept in the design system. A multi-criteria decision matrix is used for the selection of the best façade technologies within the market while the analysis of the existing building conditions allows to develop a replicable approach for designing deep retrofitting intervention through a plug&play façade. The methodology appears to be a valuable support for the selection of technologies and allows to define a design guideline for the envelope.

AbstractRising global emission have led to a renewed popularity of timber in building design, including timber-concrete tall buildings up to 18 stories. In spite of this surge in wood construction, there remains a gap in understanding of long-term structural behavior, particularly wood creep. Unlike concrete, code prescriptions for wood design are lacking in robust estimates for structural shortening. Models for wood creep have become increasingly necessary due to the potential for unforeseen shortening, especially with respect to differential shortening. These effects can have serious impacts as timber building heights continue to grow. This study lays the groundwork for wood compliance prediction models for use in timber design. A thorough review of wood creep studies was conducted and viable experimental results were compiled into a database. Studies were chosen based on correlation of experimental conditions with a realistic building environment. An unbiased parameter identification method, originally applied to concrete prediction models, was used to fit multiple compliance functions to each data curve. Based on individual curve fittings, statistical analysis was performed to determine the best fit function and average parameter values for the collective database. A power law trend in wood creep, with lognormal parameter distribution, was confirmed by the results.

Abstract This study investigates the stability of timber members subjected to simultaneously acting axial compression and bending moment, with possible risk for torsional and flexural–torsional buckling. This situation can occur in laterally supported members where one side of the member is braced but the other side is unbraced. In this case, the free side will buckle out of plane while the braced side will be prevented from torsional and flexural–torsional buckling. This problem can be evident for long members in timber-frame structures, which are subjected to high axial compression combined with bending moments in which the member is not sufficiently braced at both sides. This study is based on the design requirement stated in Eurocode 5. Solution methods discussed in this paper can be of interest within the framework of structural and building Engineering practices and education in which the stability of structural elements is investigated. Article Highlights This case study investigates some design situations where the timber member is not sufficiently braced. In this case, a stability problem associated with combined torsional buckling and flexural buckling can arise. The study shows that the torsional and/or flexural–torsional buckling of timber members can be important to control in order to fulfil the criteria of the stability of the member according to Eurocode 5 and help the structural engineer to achieve safer designs. The study investigates also a simplified solution to check the effect of flexural torsional buckling of laterally braced timber members.
