<p>According to urban theorist Jan Gehl (2004), Wellington’s central business district (CBD) lacks pedestrian vibrancy. Gehl identifies impermeability, caused by many large footprint commercial buildings with closed street frontages and privatised ground floors, as the main weakness in the city’s urban fabric . This thesis seeks to address Gehl’s findings that commercial buildings create a sterile pedestrian environment because of their disengaged street frontages, lack of programmatic diversity and negative impact on the connectivity of the pedestrian network.  A current lack of high end commercial office buildings in Wellington’s CBD creates an architectural opportunity to reconsider the way in which office buildings are integrated into the urban environment. In this thesis the office building is used as a tool to realistically investigate how these new buildings can address the urban issues raised by Gehl, and enhance the pedestrian experience.  This research uses the design principles in Nan Ellin’s Integral Urbanism to find a solution for the urban problems identified by Gehl. Three architectural and urban principles are used as devices to integrate the vertical office tower into the horizontal streetscape; hybridity, porosity and connectivity. This design proposition investigates an office building on the corner of Jervois Quay and Willeston Street in the Wellington CBD. This site is identified as a particularly weak area of the urban fabric challenged by a disconnection from the nearby waterfront; by the six lane highway, Jervois Quay.  The site-specific problem combined with the challenges of the market driven Wellington office typology is explored through an iterative design process to create a commercially feasible, site-specific design solution. Ultimately this research found that through applying urban design principles, office towers can better integrate into the urban environment to create a more pedestrian orientated city.</p>

The market of Adaptive Building Skins has been growing at a slow but incremental speed, as these technologies ensure better indoor climatic comfort and more efficient energy management than traditional solutions. Nonetheless, if we acknowledge the building as a system of physical qualities oriented to overall environmental performance, the resource optimization has to be extended to considering a wider range of environmental impacts along the entire building life cycle. For this purpose, the Life Cycle Assessment (LCA) method is recognized by stakeholders as the most world-renowned standardized tool for weighting environmental impacts. The aim of this study is to scrutinize the state of the art of LCA among stakeholders enrolled in the design and manufacturing of building and adaptive facades in the Italian market. Data have been collected throughout interviews and an online survey focusing on investigating the knowledge and experience level of participants. Results not only draw the attention to develop new market models by implementing sustainable building protocols concerning adaptive technologies, but also provided a positive assessment on the usability degree of a parametric design mapping based on a systemic and life-cycle-oriented approach to achieve environmental scopes and introduce competitive factors and boost innovation in the Italian building industry.

The Impact

Extensive cost in the building industry comes from cooling and heating to create thermal comfort. Hence, it is necessary to utilize passive solutions, in addition to suitable design, in order to reduce energy consumption. This research attempts to investigate the impact of archetype patterns in office buildings on annual energy consumption for cooling, heating and daylight loads. For this purpose, the DesignBuilder software was used to compare the forms. In this study, four conventional construction forms were considered, including the single and dense form, central courtyard buildings, U form and linear form, and each was considered with two, four and six-stories. Forms were simulated in the three cities of Bushehr, Shiraz and Tabriz, with hot-humid, hot-dry and cold climates, respectively. The results revealed that the office building with a linear form in Bushehr had the lowest energy consumption in the two and four-story forms, and also in the six-story form, the central courtyard form had the lowest energy consumption. Additionally, the central courtyard forms in Tabriz and Shiraz had the lowest energy consumption in all cases. Finally, the linear form possessed the most natural daylight through all of the studied cases for the three cities in terms of natural light gain.

Shading Device

(1) Background: considering multiple, and somehow conflicting, design objectives can potentially make achieving a high-performance design a complex task to perform. For instance, shading devices can dramatically affect the building performance in various ways, such as energy consumption and daylight. This paper introduces a novel procedure for designing shading devices as an integral part of daylightophil architecture for office buildings by considering daylight and energy performance as objectives to be optimal. (2) Methods: to address the topic, a three-step research method was used. Firstly, three different window shades (fixed and dynamic) were modeled, one of which was inspired by traditional Iranian structures, as the main options for evaluation. Secondly, each option was evaluated for energy performance and daylight-related variables in critical days throughout the year in terms of climatic conditions and daylight situations (equinoxes and solstices including 20 March, 21 June, 22 September, and 21 December). Finally, to achieve a reliable result, apart from the results of the comparison of three options, all possible options for fixed and dynamic shades were analyzed through a multi-objective optimization to compare fixed and dynamic options and to find the optimal condition for dynamic options at different times of the day. (3) Results: through different stages of analysis, the findings suggest that, firstly, dynamic shading devices are more efficient than fixed shading devices in terms of energy efficiency, occupants’ visual comfort, and efficient use of daylight (roughly 10%). Moreover, through analyzing dynamic shading devices in different seasons and different times of the year, the optimal form of this shading device was determined. The results indicate that considering proper shading devices can have a significant improvement on achieving high-performance architecture in office buildings. This implies good potential for daylightophil architecture, but would require further studies to be confirmed as a principle for designing office buildings.

Abstract- Many of high-rise office buildings in Indonesia applies efficiency and effectivity of building form, cost, and time for construction as a number one priority. As a result, high-rise office buildings appears with a minimum-articulated form, and show the dominance by using glass materials as a facade. However, there are also high-rise office buildings that have an articulated form and its facades that are not dominated by glass, although they appear in small numbers. Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya are one of them. Moreover, both buildings were designed by foreign architect, Paul Rudolph. Based on the potentials of both buildings, this research focused on Paul Rudolph’s principles in designing high-rise office buildings in Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti SurabayaLooking at the phenomena of high-rise office buildings in Indonesia as described earlier, this small number and the articulated form of high-rise office buildings designed by Paul Rudolph in Indonesia are interesting to be understood even more. The main purpose of this research is to reveal the relationship between Paul Rudolph’s design principles with buildings, which are Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya. Using an interpretative method in a qualitative research, this research utilized theories that helps understanding of an office building, theories that related to Paul Rudolph’s background and common thought about architecture, and also Paul Rudolph’s theory about determinants of architectural form as a literature study. Building’s Anatomy Theory is used as a surgical tool to disect the study cases, which happens to be Wisma Dharmala Sakti Jakarta and Wisma Dharmala Sakti Surabaya.Result of this research are six points of Paul Rudolph’s principles in designing high-rise office building which are: repetition, space, scale, rotation, light, and context. Implementation of Paul Rudolph’s design principles in both study cases can be seen in the dominance of rotation and repetition of building elements. The application of these two principles can fulfill all the three aspects of Paul Rudolph’s design ideal, which are form, context, and cycle.Benefit of this research is to enrich architectural vocabulary about design principles of a high-rise office buildings in Indonesia for the concerned educational institution, as a consideration and input to architects and the stakeholders to be more sensitive and critical in designing high-rise buildings in Indonesia, as a reference and study case about design principles of a high-rise office buildings for students, academics, architects, and the public with the focus of study concerned, and enrich the knowledge about Paul Rudolph’s design principles especially in designing high-rise office buildings in Indonesia for researcher. Keywords: Paul Rudolph, Design Principles, Office, Wisma Dharmala Sakti Jakarta, Wisma Dharmala Sakti Surabaya.

Purpose – The purpose of this paper is to address two major challenges faced by sustainable building owners: first, address the gap between an occupant’s expectations of sustainable building outcomes and what the building actually provides and second, overcome the lack of user knowledge about sustainability design and operation for a particular with regards to performance. Design/methodology/approach – This study used a focus group approach to investigate the gap between: user expectations and sustainable building performance. The study surveyed occupants of sustainable office buildings in Melbourne, Australia. Findings – There is no significant relationship between users’ expectations and users’ experience of sustainable building performance and users’ knowledge about sustainability and the building they were worked in. Research limitations/implications – The research was limited to sustainable office buildings. New office buildings seeking to incorporate sustainability which need to focus on the needs of tenants in order to maximise value. Practical implications – There is an urgent need to ensure sustainable office buildings meet the needs of present and future occupiers without compromising short and long-term occupier satisfaction levels with regards to sustainability and operation of the building. Social implications – Increasing the level of sustainability in office buildings has been a major trend over the past decade however the tenants need to be consulted in the post-occupancy phase. Originality/value – Little attention has been given in the property management literature to sustainable office buildings and value drivers. This is an original and innovative study, partly due to the recent developments in sustainable buildings.

Sustainable development is a priority for the future of our society. Sustainable development is of particular importance to the Architecture, Engineering, and Construction (AEC) industry, both for new buildings and for the renovation of existing buildings. Great potential for sustainable development lies in the renovation of existing office buildings. This paper introduces a new framework for identifying the best set of renovation strategies for existing office buildings. The framework applies selected green building rating system criteria and cost-effective sustainable renovation solutions based on cost-benefit analysis (CBA), and thus provides a novelty in decision-making support for the sustainable renovation of office buildings at an early-stage. The framework covers all necessary steps and activities including data collection, determination of the required level of renovation, selection of the green building rating system, identification of impact categories and criteria, and final evaluation and decision-making using CBA. The framework can be used in conjunction with different systems and according to different regional characteristics. The applicability of the addressing procedure is shown through a case study of a comprehensive renovation of an office building in the city of Maribor.

Convolutional neural networks (CNN for short) have made great progress in face detection. They mostly take computation intensive networks as the backbone in order to obtain high precision, and they cannot get a good detection speed without the support of high-performance GPUs (Graphics Processing Units). This limits CNN-based face detection algorithms in real applications, especially in some speed dependent ones. To alleviate this problem, we propose a lightweight face detector in this paper, which takes a fast residual network as backbone. Our method can run fast even on cheap and ordinary GPUs. To guarantee its detection precision, multi-scale features and multi-context are fully exploited in efficient ways. Specifically, feature fusion is used to obtain semantic strongly multi-scale features firstly. Then multi-context including both local and global context is added to these multi-scale features without extra computational burden. The local context is added through a depthwise separable convolution based approach, and the global context by a simple global average pooling way. Experimental results show that our method can run at about 110 fps on VGA (Video Graphics Array)-resolution images, while still maintaining competitive precision on WIDER FACE and FDDB (Face Detection Data Set and Benchmark) datasets as compared with its state-of-the-art counterparts.
