Abstract text During World War II, over 10,000 buildings across North Norway were burnt to the ground by the German military in a scorched earth policy. In the aftermath of the war, over 20,000 reconstruction houses, ´gjenreisningshus´, were built to rehouse the population. Based on a set of standard designs, with some variations, these homes were a new architectural style for the north, and were usually placed and aligned in a standardised way in accordance with contemporary ideas on urban design.

The University of Tromsø´s Northern Homes 21 research programme is considering these homes in a range of ways: historical and cultural, and in terms of their potential for being incorporated into the green shift through new technologies. One of the options being examined is the potential to integrate photovoltaic panels into the roofs and other locations. To provide information on the potential for solar availability, a methodology and methods are being developed to produce a database that will include: roof alignment, biological conditions, and localised elevation data to ascertain any obstructions by landforms or other structures.

Central to the research is respectful engagement with the Peoples of the North to coproduce knowledge requested by them. There will be a strong emphasis on providing communities with opportunities and support for knowledge and transfer of skills in utilising remote sensing resources.

Remote sensing data from spaceborne platforms are expected to provide significant input to the programme. Roof alignments will be extracted from sub-metre resolution imagery using machine learning methods, and Digital Elevation Models and estimates of building density will be used to estimate seasonal insolation factors. Remote Sensing data at coarser resolution will also be used to model climate interactions with the urban fabric and to characterise the urban-rural setting. Remote sensing has several potential applications to the safety assurance aspects of the Northern Homes 21 project. Regeneration of the historic built environment needs to occur within the modern legal context and the associated safety expectations. To meet these, it is hoped to utilise remote imagery of northern Norway to complement other techniques in creating a safety assurance justification for the regeneration. Remote sensing imagery would prime a comprehensive map of the NH21 properties, identifying their orientation relative to anticipated future wind directions, separation from adjacent properties and the potential combustibility of surface material on the surrounding terrain. The product of this analysis would have a number of components. First, a catalogue of properties by risk level for local fire services, to assist in the planning of fire prevention and response. Second, data to prime models for virtual firefighter training. In addition, the data would be used in the planning of new infrastructure such as external batteries and other energy storage facilities. This would identify minimum safe distances to ensure that in the case of fire, the incident heat flux on surrounding structures – particularly the wooden buildings that are the focus of this project – remains lower than the 12,6 kW/m2 value adopted in many building codes (Pesic, et al. 2018.
