A detailed study on the building stock of Liege urban area (Belgium) has been conducted during 2011-2012. The study is focused on historic buildings, which were constructed before 1945 and represents a very significant share (68.33%) of Liege building stock. …
Among the policies and regulations aimed at reducing the energy use in building stocks, the retrofit of historic buildings is one of the hardest challenges both for research and practice, because it is necessary to combine the traditional energy/economy targets …
Buildings have a significant impact on energy use and the environment. Across the European Union, they are responsible for approximately 40% of the energy consumption and 36% of CO2 emissions. The majority of buildings in Europe are located in cities, …
The research project EEPOCH consists of a multiple case study. It has been carried out over three years, studying selected buildings restored within the Halland Model. EEPOCH was permeated by traditional system thinking for solving complicated problems during its first …
Retrofitting of existing buildings offers significant opportunities for reducing global energy consumption and greenhouse gas emissions. This is being considered as one of main approaches to achieving sustainability in the built environment at relatively low cost and high uptake rates. …
The energy policy about energy performance of buildings, including minimum energy requirements and energy performance certificate (EPC), is applied to new and existing buildings, especially in the case of energy retrofit. Among existing buildings, heritage buildings are a special case. …
Since historic buildings constitute 25% of the European built environment they have a role to play in delivering CO2 emissions reduction targets along with the rest of the domestic stock. However, historic buildings have significant cultural value and were built …
Worth aged buildings represent among the existing buildings a special case when it comes to their energy refurbishment. Unfortunately, the available technologies for building components characterized by high level of thermal performances show, not rarely, a limited compatibility with the …
From an economic point of view, it is crucial to minimize the life cycle costs (LCC) of buildings undergoing energy renovations, hence an optimization approach is needed. Building energy use and power demand as well as energy efficiency measures are …
The life cycle cost (LCC) optimization is a vital method when performing building energy renovation. The present paper provides an evaluation of cost-optimal energy renovation strategies for historic buildings using LCC optimization software OPERA-MILP. The evaluation is performed based on …
