Purpose: Hospital construction projects often suffer from relatively late changes in the project lifecycle, which disrupt the project execution and impact project productivity. The purpose of this paper is to explore the root causes of changes in hospital construction projects. The paper aims to propose ways to prepare for the changes. Design/methodology/approach: The study focuses on changes duri

Pedestrian dynamics is concerned with understanding the movement patterns that arise in places where more than one person walks. Relating theoretical models to data is a crucial goal of research in this field. Statistical model fitting and model selection are a suitable approach to this problem and here we review the concepts and literature related to this methodology in the context of pedestrian

This paper provides an overview of Subtask B: Tools and methods for solar design, of IEA SHC Task 41: Solar energy and architecture, 2009-2012. The focus of this Subtask was on identifying obstacles that architects are facing when implementing passive and active solar strategies in their design, especially during the early design phase (EDP) of building projects. The results of this Subtask also a

Människans reflektioner över etiska frågeställningar befinner sig i spänningen mellan att formulera vad som är allmänmänskligt och vad som kan betraktas som särskiljande för olika individer och grupper av människor. Hur ska vi leva tillsammans? Och vad är ett gott samhälle? Det som ska vara gemensamt och gränserna för olikhet måste (åter)erövras i varje tid. Och i varje tid samsas ”eviga” etiska s

A method is presented for assessing daylighting quality based on metrics related to illuminance, distribution, glare and directivity. The calculations are done using the programs RADIANCE and DAYSIM for a south-west and a north-west oriented offices in the CDP building in Montreal (latitude 45° 30'N). The results indicate that the following set of metrics is the most useful for assessing the dayli

This article presents the results of a study where the effect of five window glazing types on daylight quality was investigated using a scale model (1:6) of a room with a single, south east-oriented window exposed to the natural sky. The space studied simulated a typical, fully furnished living room. A total of 30 research subjects took part in the experiment, observed the room and filled question

The impact of seven shading devices on daylight quality in a south-oriented office was investigated by simulations with Radiance at three specific times on three sunny days. Daylight quality was assessed for a large number of desk positions by considering simple performance indicators: the absolute and relative work plane illuminance and the absolute and relative luminance of surfaces. The results

What has previously been referred to as terrorism or ideologically motivated crime in Sweden has recently increasingly been referred to as violence-affirming extremism. The new language use implies an expansion of the focus from actual violence use to including also those groups and ideologies that affirm the use of violence to fulfill political goals. The significant changes in the new language u

Establishment in flocks by juvenile marsh tits, Parus palustris, was simulated in outdoor aviaries. Encounters between established and intruding juveniles were won by the established ones, irrespective of sex, size or age. As existing flock size increased, establishment became successively harder. Intruding females received less aggression from already established juveniles than did intruding male
