Heritage Buildings

Sustainable design is believed to stand on the opposite side of heritage conservation. This view is supported by the fact that sustainable design requires invasive measures to implement new technologies and treatments that challenge the principle of minimum intervention in heritage conservation. Another point of view sees heritage conservation as an already act of sustainable development that protects and preserves social and cultural resources such as heritage buildings and their intangible values. On the other hand, research and practice have proven that heritage buildings can be the subjects of sustainable design projects that achieve outstanding measures of sustainability and energy efficiency while not compromising the authenticity of the heritage value of the building. This sustainable conservation reaches its peak in adaptive-reuse projects of heritage buildings as reusing the building guarantees its ongoing maintenance and promotes its social, cultural and economic values to society, while giving it the ability to withstand modern users’ comfort and energy efficiency standards. This research presents a case study of the adaptive-reuse project of Villa Antoniadis in Alexandria; a heritage building built in the mid-nineteenth century and in the process of a major adaptive-reuse project. The history and significance of the building will be studied as well as the conservation values of the current project, then some proposals for interventions that could achieve more energy efficiency for the project while conserving the building are discussed. The research included a simulation of the building, using building energy modelling software for the current adaptive-reuse project as a base case, and the hypothetical application of different proposed sustainable interventions such as thermal insulation, double glazing, shading, lighting control, natural ventilation, and photovoltaic energy generation, where the energy savings potentials for each proposed intervention were studied. The simulation proved a possible reduction of 36.5% in the cooling, heating and lighting energy consumption as well as generated 74.7% of the energy required for cooling, heating and lighting from renewable energy sources.

A proper systematic approach to the restoration of historic buildings is crucial in the preservation of heritage buildings. This paper presents the unity between the restoration of a historic building and sustainability. The aim of the research is to establish an effective method for the restoration of historic buildings and their reuse and sustainable renovation in terms of energy efficiency, in accordance with modern needs and conservation requirements while maintaining the authentic appearance. The main method in the paper is the observation of a historic building during its restoration and exploitation, analysis and evaluation of the results achieved in improving energy efficiency and energy saving in the example of the building within the Žica Monastery in Serbia, a cultural monument of exceptional importance. The subject of the research is the Dining Room within the Žiča Monastery and the analysis of the restoration results in order to ensure energy refurbishment and cultural heritage enhancement. The research findings are recommendations for the restoration and adaptive re-use of historic buildings, in accordance with modern requirements for comfort and environmental protection. The greatest contribution of this paper is the practical verification of energy refurbishment of the restored historic building, the Dining Room, by applying the principles and measures of energy efficiency, maintaining the authentic appearance of the building, in accordance with the conservation requirements.

Historic and heritage buildings present a significant challenge when it comes to reducing energy consumption to mitigate climate change. These buildings need careful renovation, and increasing their energy efficiency is often associated with a high level of complexity, because consideration for heritage values can often reduce and impede possibilities and sometimes even rule out certain improvements completely. Despite these issues, many such renovation projects have already been carried out, and therefore the IEA SHC Task 59 project (Renovating Historic Buildings Towards Zero Energy) in cooperation with Interreg Alpine Space ATLAS has developed a tool for sharing these best-practice examples—the HiBERatlas (Historical Building Energy Retrofit Atlas). The Internet serves as a best-practice database for both individual energy efficiency measures and whole-building renovation projects. This paper presents two of the Danish projects featured in HiBERatlas. The first project, Ryesgade 30, is a Copenhagen apartment building with a preservation-worthy period brick façade. The second project is the Osram Building, a listed Copenhagen office building from 1959 with a protected façade, which today acts as a culture centre. Both renovation projects achieved significant energy savings and consequently CO2-emission reductions, and the indoor climate in both buildings have also improved significantly. Furthermore, a detailed analysis was carried out regarding possible window solutions and ventilation systems in Ryesgade 30, and for the Osram Building regarding daylighting technologies. This paper investigates the two renovation cases through the available measurement and calculation results before and after renovations and demonstrates that it is possible to reduce energy consumption significantly and at the same time improve the indoor climate without compromising the cultural values of buildings.

Abstract A guidance was developed to find a sustainable balance between energy savings and heritage preservation when retrofitting heritage buildings. It was applied in a study on the retrofitting of typical Alsatian heritage buildings. Seven buildings were analysed before retrofitting to evaluate them on five criteria: energy savings, heritage preservation but also comfort in winter and in summer and moisture damage. Then, compatible retrofitting works on walls, ceilings, floors, front door, windows, ventilation and heating and hot production water systems were selected in order to create three retrofitting scenarios: a high-energy efficiency scenario with moisture-permeable materials, a balance scenario between energy efficiency and heritage preservation and a high heritage preservation scenario. The results of the study showed that these sustainable retrofitting scenarios preserve heritage while saving energy and are available in a web publication headed to Alsatian private individuals. The guidance in itself can be easily replicated to other types of heritage buildings.
