“…The most similar finding in this investigation with existing studies 6,8,9,16–19,21,23,39 is the acknowledgement that achieving the Passive House Standard in dwellings in the Arctic is very challenging – especially at a latitude of 78° N. In particular, the finding that the one-size-fits-all space heating performance criteria of the Passive House Standard needs a climate depended adjustment. Other similarities found in this investigation with above mentioned studies are: The energy balance results of the base case ‘Kranichstein’ (Table 4) compared to the calculations of Vladykova and Rode 40 that were done for the ‘Kranichstein house’ 5 when placed in a coastal region with latitude 75° N (Figure 1): the space heating demand resulted in 58.3 versus 60 kWh/m 2 /year respectively; and the transmission heat loss resulted in 72.7 versus 75 kWh/m 2 /year respectively. The strong relationship between the absence of winter solar gains and space heating demand. The complexity and the high level of combined solutions required to reduce the space heating demand sufficiently. …”

Passive building design reduces a building’s energy consumption through mainly non-mechanical design strategies. The Passive House (or Passivhaus) Standard certifies such buildings that comply with its strict energy performance criteria. Achieving the Standard is very challenging for dwellings in extreme climates. There is limited knowledge of the Standard’s potential in Arctic regions, particularly the High Arctic. Through a review of the literature and energy modelling of a hypothetical dwelling, the challenges in achieving the Standard in Longyearbyen (78°N), Norway are investigated. Very low temperatures and 112 days without daylight create a high heating demand. Whereas previous studies measured actual building performances or used simple calculations, the findings in this investigation show the limitations of individual design parameters and technical limits of the building envelope. In theory the Standard can be achieved in Longyearbyen; however, the potential in practice is low due to the very tight margins in the heating criteria. The results show the significant impact of applying contextual (climatic) adjustments to the boundary conditions of the Standard. The investigation could contribute to a discussion on modifying the Passive House Standard for dwellings in the High Arctic and improving building design for the region. Practical application: Current knowledge regarding energy efficient building performance in Arctic climates is limited, while the urgency for improved efficiencies is extremely high. The modelling in this work shows the valuable impact of contextual adjustments to the Passive House boundary conditions; the impact of individual design parameters; and the potential for significant energy savings through adopting passive house principles for dwelling design in Longyearbyen or similar climates. This investigation could encourage new policy making, additional research and the development of an optimized Passive House Standard that considers High Arctic climate conditions, thus encouraging new energy efficient building construction in cold climates.

“…Although increasing the use of local labour is an objective for most of the countries having Arctic territories (Arctic Council, 2001; Thirunavukarasu et al. , 2015; Nenasheva, 2019) and community participation is known to be a key in the successful fulfilment of projects (Carillion, 2017), the lack of skilled labour and transportation remain a challenge (Vladyková, 2011).…”

PurposeRemote and isolated indigenous communities in Nunavik (Canada) currently face a number of housing related challenges. This paper proposes a conceptual framework to identify the factors affecting value creation within the supply chain of social housing construction in that region. The term “social” refers to the fact that governments subsidise construction and operation of these buildings intended for low-income households.Design/methodology/approachThe research used a literature review and information collected from 3 semi-structured interviews with key stakeholders to identify the desired features of improvement or solutions (e.g. prefabrication) with respect to value creation. A SWOT analysis, an influence/dependence map and a causal loop diagram were developed to represent the supply chain.FindingsLocal job creation and the number of buildings to build were identified as the key factors that can roughly represent value creation. Energy resources, construction time, type and amount of labour force, shipping constraints, number of replacement parts and waste disposal were identified as the main factors constraining the range of solutions to implement.Practical implicationsThe framework can be used to support the decision-making in supply chain management and the design of solutions for remote areas such as Nunavik.Originality/valueThis paper is the first to analyse value creation in social building construction in remote and isolated communities such as those from Nunavik. Conceptual models achieved within the framework allowed identifying the factors that could roughly represent this value creation, as well as logical relationships that link them with other factors.

“…Figure 7 represents the temperature graph for the site, and it shows a significant variation in temperature from winter to summer, where the temperature goes below zero and gets extremely cold. A similar study [16][17][18] indicates how important it is to keep all variables like moisture, fluctuating temperature, snow and gust into account while planning the house. Because of the humid nature of the climate, dehumidification is also required during certain times in the year to maintain an indoor comfortable living environment.…”

This paper present the building performance of a house in Newfoundland, Canada. This house is built under the guidelines of the Passive House Institute United States (PHIUS+2015) standards. This is an important step took towards sustainable living in Newfoundland and Canada in general. Detailed energy consumption modelling of the house has been performed along with the steps involved in the simulation process of Passive House planning and renewable energy system sizing. A significant part of the study presents the majority of the construction details of the house and the components involved. In this study, we present actual energy consumption data acquired from the house and the simulation performed in both preconstruction and post-construction phases. Additionally, steps followed during the planning and construction phase have been discussed in detail, and both static and dynamic energy modelling has been compared. Moreover, a cost comparison has been performed to calculate all the additional costs spent on the resources to build the house according to the Passive House (PHIUS+2015) standards; the analysis indicated a cost of 12% extra when compared with the house built under local regulations. Finally, a renewable energy system is proposed for the house to meet the electricity needs of the house.
