“…The systems have had some problems in meeting users' expectations, since the energy-saving systems work counter intuitively to the expectations of the inhabitants. This interaction between house and inhabitant can become increasingly problematic with the shifting climate, as the house has to employ cooling measures with greater frequency (Hansen et al 2013).…”

Climate change is a threat. Houses we inhabit should conform to changes in the environment. The housing sector is vulnerable to climate changes, since the inhabitants are more exposed than in commercial buildings. Studies find modern sustainable buildings are at risk from thermal changes due to lower resilience from a focus on energy savings. Through simulation studies of three sustainable houses in Denmark, their viability to climate change is tested. Four thermal adaptation strategies were simulated: defensive, reactive, embedded, and air conditioning. The operative temperature and energy use for heating is registered for occupancy rooms in the buildings. The simulations show a tendency that adaptation through passive means use the same or up to 5% less energy as the unmodified buildings in the simulations but are unable to uphold thermal comfort, where active technologies use 25%-260% more energy than the baseline in 2080. Reactive strategies provided best thermal comfort in most rooms and scenarios, balancing energy and thermal environment. Air conditioning removed most thermal discomfort but increased the energy use with 45%-260% by 2080. The recommendation would be to enable upscaling of mechanical ventilation by a factor of two over the minimum regulation of 0.3 l/s/m 2 with the ability to bypass heat recovery, aided by passive solutions such as strategic planting of deciduous trees and solar shading to reduce energy use further.

“…The houses are primarily constructed by prefabricated elements. Therefore, Danish residential architecture might have some adaptive capacity in the high-tech system integration, due to the use of active technologies in plenty of the sustainable houses that have been designed both for testing and habitation to meet the strict and increasing energy standards of the Danish building code [22], [28]. The houses that already adapt to changes over seasons and could be resilient, if the systems are designed with a level redundancy.…”

Vulnerabilities and resilience in Danish housing stock: A comparative study of architectural answers to climate change in Danish housing in relation to other oceanic climates

Climate change will affect the same climate zones relatively similarly. When considering how to design residential architecture for future climates it is therefore relevant to understand how residential architecture can adapt within the specific climate zone. Denmark is placed within the oceanic climate zone and shares many of the same problems that countries in similar climates do. However, the architectural responses have developed radically different. Denmark has been building heating efficient housing for the last decade, which have lately caused increased overheating problems and surging energy demands for cooling. This paper compares the architecture of different oceanic zones with Danish architecture. The strategies for adapting to climate change represents a broad variety. Western European tradition has itself created varied methods for coping with the climatic struggles their societies meet. Danish architecture has for centuries been focused on heavy robust constructions that would withstand the large amount of precipitation and wind that is predominant in the country. In Holland flood danger has been a constant threat to society, which has led both to defensive and reactive measures in the form of dykes and amphibious housing. On the other side of the globe, New Zealand’s traditional architecture has adapted to similar problems but with a much lighter construction, leading to architecture that is resilient to lateral forces like wind and earthquakes. While lacking the thermal properties of northern European houses the New Zealand homes show a remarkable flexibility and mobility through simple timber-frame constructions. The vulnerabilities in the Danish building stock is due to an unwillingness to invest in adaptive measures. It might be necessary to integrate a flexible building style to future sustainable housing and build up a different expectation for how a house is used. In the face of climate change, architecture need to be adapted to the problems apparent on the building site and draw on experiences from other cultures that might have faced similar problems in the past. Danish architects might likewise use the non-rocky ground for water retention through planting and landscaping strategies in relation to architecture.

“…This implies that these developer-driven sustainable buildings often lack any kind of connection with the landscape or any actual understanding of the climate or of climate change. In Denmark, the discourse on climate change with regard to the building stock is centered on precipitation and flooding, which is the most immediate economic threat to the building stock [18,19].…”

The Historical Influence of Landscape, Ecology and Climate on Danish Low-rise Residential Architecture

architecture has historically had to respond to landscape, ecology and climate. The paper investigates how this relationship has developed in Danish architecture, and how architecture of the future may develop during climate change. Through literature studies on the subject of Danish low-rise residential architecture and on climatic adaptation, it has been examined how late vernacular, modernistic, regional, modern and ecological/sustainable residences have responded to landscape and climate. Vernacular architectural designs were based on inter-generational knowledge of how to design according to the landscape and environment with materials locally available within communities. The connections with the landscape were intrinsic but were wholly anthropocentric by necessity. The 1920s' introduction of modernism and the International Style reduced the importance of local landscape and climate. Danish architects of the era started to incorporate architectural elements and colors from foreign climates, at the expense of lessons from the vernacular. The regional modernism in Denmark sought to reconcile a regional architecture with the functionality of modernism. This architecture was better suited to the local climate and connected with local materiality. The 1960s saw a demographic and housing boom, the consequence of which was hastily built 'cookie-cutter' housing and concrete apartment blocks that still dominate the housing stock. The oil crisis of the 1970s hit Denmark hard, enforcing energy savings on architecture, which over time developed to become reliant on passive solar strategies and thermal mass. The current Danish sustainable architecture has a primary focus on minimizing greenhouse gas emissions; the control of the indoor climate diminishes the connection to the exterior environment. Danish architecture must merge the vernacular understanding of climate and landscape with the mitigating properties of sustainable architecture. an embedding in the landscape and climate will reduce the impacts of climate change.
