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.

Underflow baffles have gained in popularity over the years as a viable mean to intercept floatables in Combined Sewer Overflows (CSOs). This choice was mainly justified by the extremely low capital cost (CAPEX) and operational cost (OPEX) of this solution, although the efficiency of underflow baffles has never been clearly proven. The only similar application to underflow baffles are scum boards in grit chambers and clarifier. However, the flow conditions at CSOs vary considerably from those in grit chambers and clarifier. For this reason, review of the behavior of floatables in a rapid flow is paramount. Only then can comprehensive design criteria for underflow baffles and overflow chambers be suggested. Pilot scale tests, performed in a 17 metres long basin at various flowrates, had already shown that a critical horizontal velocity for floatables (Vcr) may develop in the overflow chambers. In this follow up study, the fate of intercepted floatables was investigated. It appears from this latest data that permanent capture of floatables decreases rapidly with an increase in the horizontal velocity of the flow, no matter what the baffle depth. Baffle depth increases capture at lower velocities (0.17 m/s) but become irrelevant at higher velocities (0.61 m/s). This data suggests that capture efficiency of existing underflow baffles in overflow chambers can be, at best, very low whenever the horizontal velocity increases above 0.30 m/s or 1 ft/s.

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.

Underflow baffles have gained in popularity over the last few year as a viable means to intercept floatables in Combined Sewer Overflows (CSOs). This has happened although the efficiency of underflow baffles has never been clearly proven. Furthermore, there are no guidelines helping planners in the correct and efficient design of underflow baffles. This article proposes design criteria deduced from pilot scale essays performed in a 17 meters basin at various flowrates. These new informations can be used in two different ways. First, these criteria can be used to correctly design a new overflow chamber. Secondly, these criteria can be used to evaluate the efficiency of existing overflow chambers. Preliminary analysis of existing chambers show that interception efficiency of floatables can be very low.


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.
