Following upon the Stockholm exposition in 1930 and the introduction of a new aesthetical and architectural thinking, some Swedish building companies and real estate owners fully embraced the new ideal. They started to assemble their own socio-political welfare ambitions concerning housing with additional services into housing projects. From 1930 to the beginning of the Million Housing Project in 1965, innovative building projects by either of these players, especially in the larger Swedish cities like Gothenburg, Malmö, and Stockholm, were realized. The project targeted different user groups in different ages, with different social background and preferences, stretching from collective housing to individualized design solutions. In these projects, both aesthetics and architecture played an essential role as material and immaterial assets for promoting the new housing and the long-term management of the estate. An often-used term in colloquial Swedish for this type of building with subsequent real-estate management is the Master Builder’s Management model, in the following MBM model.The MBM model refers to a former legal requirement of the first national Swedish building act of 1874 that building entrepreneurs had to be approved by the municipal building administration as means to avoid overcrowding in poorly built housing. Even after the reform of the building act in 1931, the title was associated with great societal esteem, but achieved during the rest of the 20th century a connotation of being either obsolete or representing building quality. The MBM model is in stark contrast to management models that have evolved since the 1990s. These models are influenced by new public management in which the practical knowledge of building and maintenance becomes secondary to financial calculations and predictions.Nevertheless, the large majority of privately owned Swedish rental housing companies are managed according to principles that can associated with the MBM model. These principles suggest a continuous maintenance in line with the aesthetical and architectural vision, careful alignment between tenant profile and type of flat, and financial planning based on building degradation and local knowledge of market. The present study is focused on a housing company in the city of Malmö which openly adheres to the MBM model. Preliminary findings suggest that the choice of management model can be related to a personal view by the company owners that is motivated by an emotional attachment to the building craft and the building itself. The combination of architecture and an engaged ownership constitutes a complex system of agency in which maintenance, tenants and mutual connections creates a specific being-in-the-world-ness of real estate management. This phenomenon seems to be an essential factor for creating successful smaller rental housing companies that are mainly active on a local market.

The National Board of Housing, Building and Planning (Boverket) has initialized a compilation of knowledge about the current situation in Swedish ventilation. The purpose being to summarize an as broad and correct understanding as possible of who the industry is, what rules that applies, where there are knowledge centres and what development needs are required to be supported for the industry. Ventilation systems has developed from simple to high-tech sensor-controlled with the main task of removing unwanted airborne substances (e.g. odours) and excess heat, in an energy efficient way. 

Data was collected from stakeholders dealing with ventilation and indoor climate. A group of knowledgably consultants and scientists have collected information, analysed different aspects of ventilation, and presents the results in a report available in Swedish. 

Ventilation situation in residential buildings varies from other types of buildings that house widely differing businesses. Different types of activities place different demands on the buildings' air quality, thermal comfort, etc. For the operation of a building, it is important to clarify the conditions and requirements that determine needed airflow. Quite small, oversights and mistakes can ruin the possibilities for the ventilation system's to function properly. 

The main outcome of the project is the presentation of the state-of-the-art position of ventilation in Sweden. Ventilation is a vital part of the building's system and the prerequisites for correct ventilation function. Seemingly, banal user behaviours can have a major impact on the control of the indoor climate. 

Regulations and rules that govern and apply for ventilation and indoor climate comes from a number of international, national organisations. More than ten Swedish authorities define regulations influencing ventilation. This affects how measurement and verification of indoor climate and ventilation can take place with different methods and instruments depending on which properties are studied. 

The survey contributes to the dissemination of knowledge about the industry, stakeholders, technology, systems, construction, controls, operation and maintenance as well as research and development. 

Stakeholder management is an important task for project managers in housing renovation. Compared with new construction project, a great challenge is managing the tenants living onsite before or during the renovation. This paper is a teaching case based on a real-life housing renovation of a Swedish real estate company between 2009 to 2016. The project confronted difficult stakeholder management problems. The case provides teaching materials that can be used by instructors for helping students and trainees to analyse and summarise the lessons learned from a troublesome stakeholder management process and to come up with suggestions that will ensure a smooth implementation of the housing renovation project. The case contains two main parts, namely the case description and teaching notes. It can be used by teachers and trainers, as well as university bachelor students and industrial practitioners in courses and training programs about real estate project management.

This article applies Hirschmans’ concepts exit, voice and loyalty to a Swedish case of housing renovation in an estate with comparatively strong tenants. Renovations can be considered as shocks or critical junctures to an existing tenant-landlord relation, and therefore expose power relations on the housing market. Renovation processes are complex both technically and socially, and our study indicates that the exit, voice and loyalty framework is a useful tool for analysing such processes. In the case studied, tenants were not able to affect the renovation process per se, but tenant voice did affect the outcome in other respects. We argue that this strong tenant group represents an extreme ‘most likely’ case, making it possible to test the limits of tenant influence.
