Passivhaus or Passive House buildings are low-energy buildings in which the design is driven by quality and comfort, hence achieving acceptable levels of comfort through post-heating or post-cooling of fresh air. Additionally, Passivhaus building design follows the Passivhaus design criteria, as described in the Passive House Planning Package (PHPP). This article aims to introduce the Passivhaus background, development, and basic design principles. Finally, it also presents a brief description of the performance of Passivhaus buildings.

Well-being is an ephemeral condition in relation to the complex system of interconnected components changing from culture to culture and person to person together with time and space. Therefore, it is very important to investigate the intersections of architecture and humanities in order to understand how design can contribute to the way we build up well-being. The specific contribution of this chapter is the introduction of the well-being framework for interiors and its application to design process. The framework proposal, consisting of contextual, functional, psychological, social, ergonomic, aesthetic, and sensory requirements as basic design criteria, aims to support both theoretical and practical activities regarding well-being in all living environments. Since interior space is one of the most important determinants of our everyday experiences, its role in well-being as a conscious construct needs to be an important concern of spatial design.

Our objective was to develop basic design criteria for use in fabricating a functional chamber for a red meat carcass cleaning unit. Emphasis was placed on eliminating the doors. A model carcass cleaning chamber was constructed to test effects of selected design parameters on direction and velocity of airflow. Based on data from the tests using the model, a full-scale chamber with no doors was designed, fabricated, and installed in a commercial packing plant for testing. The air moves into the chamber at both the entrance and the exit. This movement of air into the chamber prevents water droplets entrained in the air from escaping into the slaughtering area and causing condensation on the walls and roof.

The world’s first full-scale fluidized bed reactor co-disposal facility located at the Western Lake Superior Sanitary District’s (WLSSD) central waste-water treatment complex in Duluth, Minnesota, began its shakedown operation in the fall of 1979. The authors present herein basic design criteria, a system description, November 1979 system status, and areas of operational concern.


This chapter aims to propose an environmental design framework in order to contribute to sustainability with well-being criteria focusing on human factors. Designers need to handle the issue of well-being with a methodological approach, as it is very difficult to achieve with an intuitive attitude. There are several requirements that need to be fulfilled in order to create the environment that can promote user well-being. The framework proposal, consisting of contextual, functional, psychological, social, ergonomic, aesthetic, and sensory requirements as basic design criteria, aims to support both theoretical and practical activities regarding well-being in all living environments, as a crucial component of sustainability. In this sense, this chapter discusses all the components of the well-being framework and evaluates the effect of cultural differences on the hierarchy of these requirements.

The helicoids pushing chain mechanism is a novel telescopic mechanism used to push target from one position to another rapidly. The structure of the telescopic mechanism is developed and the basic design criteria are given. The position precision of the pushing chain influenced by various factors is very important to accomplish the task of pushing target. The mathematical model of position precision under the static condition is established in order to forecast the final effects and achieve some desired results by the machining. The influence of each factor is obtained through the numerical simulation. Furthermore, the bended deformation of the extended chain is calculated using the mechanics of materials method. According to the influences and the bended deformations, an error compensation method for a certain pushing distance is proposed so as to improve the position precision of chain head and achieve a satisfactory shape of the extended part. This research provides theoretical and methodological guidance for controlling machining errors and manufacturing of the pushing chain.

A new coal fired power plant constructed by the Israel Electric Corporation on the Mediterranean coast off Hadera, Israel, requires the import of 3.3 million tons of coal per year. As there is no port on the Israeli Mediterranean coast capable of handling the 60,000 to 140,000 DWT bulk carriers required for transferring of coal, several studies were conducted in order to decide on the most feasible facility for mooring and unloading these boats. Rather than expand existing ports or build a new protected port, a decision was finally taken to construct an unprotected offshore terminal at the power plant site. The terminal was designed to accommodate bulk carriers of up to 140,000 DWT in the first stage, and up to 170,000 DWT with future expansion. The design of the coal unloading terminal in an unprotected environment created the need to develop design criteria as well as operational and structural systems that will respond to problems arising from unloading bulk in the open sea. As there was no known precedent of an unprotected unloading terminal, the criteria was based on experience in existing offshore loading terminals, laboratory tests and engineering judgment. The construction of an unprotected offshore terminal, at a cost of $60 million (excluding mechanical equipment), represents a considerable saving of time and money in comparison to the expansion of existing ports or construction of a new protected facility.
