Automation systems are generally made upof three main subsystems, namely mechanical, electricaland software. The interactions among these componentsaffect the integrated system in terms of reliability, quality,scalability, and cost. Therefore, it is imperative that thethree components of automation systems are designedconcurrently through an integrated design paradigm.This leads to the need to teach integrated design conceptsto students in programs such as process automation,electrical and computer engineering, and mechanicalengineering. However, due to the time constraint, it isalmost impossible to run full integrated design classprojects. Therefore, instructors have to decide on theparts of the design process that their class projects haveto focus on, and the parts that have to be reviewed for thecompleteness of the integrated design process. In thispaper we present the design and implementation of amicrocontroller based, 3D printable, low cost robotic armsuitable for teaching integrated design. Moreover, thepaper presents how the robotic arm design is used in anintegrated design project of an Industrial Networks andControllers course. Since the focus of this course is theelectrical and software subsystems of the robotic arm,and we do not have enough time to do a full design,students review the design of the robotic arm presented inthis paper and use it to either 3D print the robotic arm orpurchase the mechanical subsystem of the robotic armthat meets the specification.

This paper discusses the application of Integrated Design Process for the design of low-cost housing in Chile. It aims to question common practice for the development of housing based on prescriptive regulations and non-interdisciplinary work, which has resulted in poor quality building requirements. The first stage consisted in defining performance requirements for aspects such as energy demand, U value, air tightness and indoor air quality for a specific case of low-cost houses located in the city of Temuco. An integrated design process was carried out by an interdisciplinary team of professionals specialized in each of the performance aspects that were taken into account. The construction and post-occupancy stages were characterized by verifying the performance requirements, which resulted in a low-cost house prototype that included strategies for energy efficiency and a healthy indoor environment.

Today, natural resources of urban areas have been given the rank of a necessary tool for combating climate change. Many cities are trying to manage biologically active areas of great quality by applying a blue-green infrastructure (BGI) strategy. Designing areas such as riverside areas belonging to BGI is particularly challenging. On the one hand, they are environmentally valuable areas requiring protection. On the other hand, they form urban public spaces subject to requirements of urban continuity as well as social and cultural conditions. The authors of the article argue that the optimal way of shaping riverside areas in cities that responds to diverse conditions (environmental, economic, legal, social) can be achieved by applying an integrated system of cooperation between designers known as the integrated design process (IDP) in the design process. The study aimed to answer the question of whether the integrated design process (IDP) that combines both the expert and social approach at the first stage, in the pre-concept phase may be optimal when developing riverside areas as part of blue-green infrastructure (BGI). The method was originally applied to architectural design, therefore the authors analyzed to what extent its assumptions may be used in the waterfront design process. First, the authors’ study compares design processes (traditional and integrated) for use in these processes of expert and social perspective. As a result, the integrated design process (IDP) has been considered as an optimal design process to create such areas. Then, the authors analyze the waterfront design process in Żmigród. The authors wanted to see to what extent the process corresponds to the assumptions of the IDP method. The authors point out the stages that implement assumptions of the IDP method partially or not at all and indicate the reasons for such a situation. The authors evaluated the role of various stakeholders. The analysis and critique of Żmigród case study presented here provide conclusions regarding the possibilities and limitations of the IDP method when implementing blue-green infrastructure projects in a small town.

Integrated Design Process

The quest for a sustainable built environment brought dramatic changes to architectural design because of the integrated design process. The integrated design process is the modern way to realize “performance architecture,” that is, design with a view to field performance. Integrated design process permits merging of concepts from passive-house designs, solar engineering, and an integration of the building enclosure with mechanical services. In part 1 of this series, the emergence of many new multi-functional materials was discussed. Yet, current innovation is guided by lessons from history. Thermal mass in heavy masonry buildings allowed periodic heating. The authors postulate integration of a hydronic heating system with the walls and the use of smart temperature control of the heating system to modify and optimize the thermal mass contribution. To use the mass of a building, one must accept transient temperature conditions where the indoor temperature varies but is confined by comfort requirements for both summer and winter conditions. On the other side, resiliency requirements dictate that in the absence of electricity the air temperature does not fall below about 12°C over a period of several hours. This requirement implies that summer cooling will likely be separated from the heating systems and that operation of a low-energy building is heavily dependent on the design of smart control systems. Analysis of control systems provided in this article for earth-to-air heat exchangers and cooling of houses with lightweight walls lead us to the requirements of separation between heating and ventilation and needs for different sources of fresh air. Finally, a new concept emerges.

Integrated Design Process

INTRODUCTION Current green building practice has been largely advanced by an integrated design process. This integrated design process involves multiple disciplines, such as architecture, civil, mechanical, and electrical engineering. The design method heavily relies on utilizing building performance simulation to illustrate how design parameters affect the energy consumption and quality of the indoor environment before actual design decisions are made (Anderson, 2014). The architectural design tools in the integrated design process supersede traditional geometrical exploration instruments, such as Sketchup, Revit, ArchiCad, and Rhino (Negendahl, 2015). More building performance simulating tools, such as Ecotect, Computational Fluid Dynamics (CFD), Radiance, and EnergyPlus, have been developed to help architects measure building performance (e.g., natural ventilation, daylighting, solar radiation, and energy uses) in the design process and attain green building standards such as Leadership in Energy and Environmental Design (LEED). The information presented by these tools guide architects at a certain level in achieving green building goals. However, building simulation is generally beyond the architect's knowledge domain. Many architects have difficulty in understanding these technical terms and models, as well as their design implications. Therefore, specific consultants have emerged to help architects grasp the meanings of these numbers and models, which require architects to implement a high level of design collaboration and coordination (Aksamija, 2015; Gou & Lau, 2014). Simulation consultants can work in parallel with architects at the early design stage to intervene in the conceptual and schematic design; they may also work behind architects to verify the building performance after the design is finished and make their design green through technical alterations. Most existing literature argues for an early intervention of building performance simulation in the architectural design process and explores different algorithms or models for optimal intervention (Degens, Scholzen, & Odenbreit, 2015; Sick, Schade, Mourtada, Uh, & Grausam, 2014; Svetlana Olbina & Yvan Beliveau, 2007). However, the difference between early intervention and late verification is often not investigated. Few qualitative studies can help understand how the building performance simulation is actually implemented, and how it influences the quality of design solutions in addition to the quantity of performance outcomes. The current research presents two case studies that compare building performance simulation as an early intervention and a late verification tool in the architectural design process, which contextualizes the building simulation research in real building practices.

The atrium space is widely found in nearly all types of architecture. In the twenty-first century, some of our values and objectives are being focused on ideas of the adaptive reuse of old building and sustainability. By selecting several cases allowing adaptive reuse of historic buildings into contemporary icons, this paper analyzes the strategies of applying atrium in the adaptive reuse of old building through the section of space and energy conservation, demonstrates the great potential that the atrium has to offer in this area. The conclusions show the “integrated design process” and sustainability can be attributed to successful execution of atria designs in the adaptive reuse.

Abstract This article investigates the feasibility of replacing metal robot links by wooden bodies for eco-sustainable design’s purpose. Wood is a material with low environmental impact and a good mass-to-stiffness ratio. However, it has significant dimensional and mechanical variabilities. This is an issue for industrial robots that must be accurate and stiff. To guarantee stiffness and accuracy performance of a wooden robot, we propose an integrated design process combining (i) proper wood selection, (ii) adequate sensor-based control strategies to ensure robot accuracy, and (iii) a robust design approach dealing with wood uncertainties. Based on the use of this integrated design process, a prototype of a wooden five-bar mechanism is designed and manufactured. Experimental results show that it is realistic to design a wooden robot with performance compatible with industry requirements in terms of stiffness (deformations lower than 400 μm for 20 N loads) and accuracy (repeatability lower than 60 μm), guaranteed in a workspace of 800 mm × 200 mm. This study provides a first step toward the eco-sustainable mechanical design of robots.
