Summary: | During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction. Most of the apartments that are in need of reconstruction is leased and residents. No matter what kind of measures as deems most appropriate in a reconstruction project, it brings the different types of disturbances that affect the residents. The major disturbances that are perceived as most disturbing of the tenants are dust, noise and difficult accessibility. Temporary electricity, water and ventilation failure are other types of disturbances that often occur at a reconstruction project. In this thesis, most of the disturbances are identified and also some approaches to achieve the best possible way to reduce them. A reconstruction project in Karlskrona was visited, where participants as the property owner, contractor, professional men and tenants were interviewed. It is important to both the property owner and the contractor to ensure the reduction of disturbances as much as possible. It is obviously not easy to eliminate some of the disturbances but through good planning, sufficient information and to set requirements to the contractor in the form of legal framework for procurement and restrictions which should be register in the AF part (General Regulations), the effect of disturbances will successfully being reduced. The key to a successful reconstruction project with minimal disturbances to residents is primarily depended on the property owner's ambition, empathy and commitment to their tenants.
