  • The built environment is in a state of change. Irish building regulations, driven by EU policy, are moving towards a nearly zero-energy standard for all new buildings. However, in the current context, the impact of new-build in reducing overall greenhouse gas emissions is limited. Ireland’s per capita emissions are among the highest of all developed countries, and existing buildings account for an important share. Moreover, in cities like Dublin historic buildings form a significant part of the building stock, and if no action is taken they could potentially hinder the achievement of national energy efficiency targets. In the European context, the EU is funding several research schemes aimed to explore and resolve the tension between the objectives of energy efficiency and building conservation. The present paper introduces parts of the Built to Last body of research carried out for Dublin City Council. This research examines approaches to achieving reasonable standards of energy efficiency in pre-1945 dwelling types of historic significance. While the issues being addressed are common to many European cities, the context of Dublin is quite unique: apartment buildings are largely absent from the urban fabric, and the dominant dwelling typology of the city has consistently been the own-front-door house regardless of scale and construction system. The study identifies that a significant proportion of Dublin districts in fuel poverty are built as long two-storey terraces with rendered concrete walls. These dwellings are located in the inner suburbs, in excellent location in terms of access to the city and public services, and their occupants often form vibrant communities. An innovative proposal is presented for carrying out large-scale energy retrofits to these terraces. The interventions feature an innovative integration of external wall insulation with extract ventilation, and are designed to improve the energy efficiency of each dwelling while ensuring minimal disruption inside the home. The scale of the works facilitates higher quality work, lower cost, and greater control and cohesion of the resulting architectural character, compared to standalone retrofits. The proposal shown here is ideally suited to being trialled, and if successful, could play a significant role in mitigating fuel poverty in Dublin suburbs and provide a valuable model for district-wide improvements in energy efficiency for terraced housing while maintaining the original architectural character.
