Abstract The Swedish National Research programme for Energy Efficiency in historic buildings was initiated in 2006 by the Swedish Energy Agency. This article gives an overview of the programme: objectives, projects and the general results of the programme. The research programme aims to develop knowledge, methods and technical solutions that contribute to energy efficiency in historically valuable buildings without destroying or damaging the historical value of the buildings, including decoration, furnishings, interiors or equipment. The programme is not limited to listed and monumental buildings but covers a wider range of historic buildings that account for a large part of the energy use in the building sector. For one and two-family houses, around 25 % of the energy use is associated with buildings built before 1945. The same number for multifamily houses is around 15 %. The programme is currently in its third consecutive four-year-stage. Previous four-year-stages were completed in 2010 and 2014. Over time, the scope of the programme and the projects have developed from mainly dealing with indoor climate control in monumental buildings towards addressing more general issues in the much larger stock of non-listed buildings. Technical research, based on quantitative analysis, dominate throughout all three stages, however most projects have had interdisciplinary components. The results from the programme have been presented in 31 journal papers, 67 conference papers, five books and five PhD theses. The projects have also contributed to CEN standards and resulted in a number of Bachelors and Master’s theses. An equally important long-term effect of the programme is that the number of Swedish researchers in the field have increased from practically none in 2007 to 18 senior researchers and twelve PhD students from ten universities in 2014. The research programme on Energy Efficiency in historic buildings is unique in an international context. Hopefully it can serve as an example for other countries on how to address an important interdisciplinary research challenge.

Energy Retrofit

One of the main targets of SHC Task 59 is to provide a solid knowledge base on deep renovation of historic buildings. The Historic Building Energy Retrofit Atlas (HiBERatlas, www.hiberatlas.com) provides a bestpractice database of exemplary energy efficient  interventions in historic buildings. The database presents bestpractice examples of how a historic building can be renovated to achieve high levels of energy efficiency while respecting and protecting its heritage significance.

The article presents the main problems of street lighting associated with the presence of large volumes of electricity losses, which are the reason for its irrational use. A method for solving these problems through the use of energy service contracts is described. The possibility of implementing these contracts together with state support mechanisms is considered, which allows for an integrated approach to achieve the main goals of modernizing street lighting systems aimed at ensuring energy conservation and improving energy efficiency. The results of the application of this approach are presented on the example of the Smolensk region, which justify the feasibility of its use.

Environmental Quality Assessment

Michigan State University and the Michigan Department of Natural Resources established a partnership for sustainable park planning in October 2011. The purpose of the partnership was to enable students in the design fields to work on real-world projects and provide practical solutions. One of the notable projects was to assess old historic buildings in one state park and propose renovation plan to improve its indoor environmental quality and energy efficiency. The buildings in the park functioned as the traveler’s destination in the 1920s and still preserve original interior and exterior features. The team of undergraduates and faculty in interior design visited the park and assessed the interior and exterior conditions of two of its buildings. They used an assessment tool which was designed on a basis of the elements in the indoor environmental quality category (IEQ) of the US Green Building Council’s LEED. Results revealed that the indoor environmental conditions of the buildings should be improved. The energy efficiency of the buildings was low. Based on this assessment, this study offered practical suggestions for improving the building’s indoor environmental quality. This study also proposed an assessment tool for the historic buildings in the state parks in Michigan to assess current indoor environmental quality of those buildings.

Support Decision Making

The UK government made significant commitments to upgrading the energy efficiency of seven million British homes by 2020, aiming at reducing carbon emissions and addressing fuel poverty. One alternative to achieve better energy performance in existing houses is retrofit. However, there are difficulties associated with retrofitting social housing. It is currently challenging to compare scenarios (retrofit options) considering costs, potential energy efficiency gains, and at the same time minimising disruption to users. This paper presents a Building Information Modelling (BIM) protocol aimed to support decision making by social housing owners. It adopts BIM to simulate alternative retrofit options, considering: (a) potential reductions in energy consumption, (b) 4D BIM for retrofit planning and reduction of users’ disruption and (c) simulation of costs. A what-if scenario matrix is proposed to support decision making in the selection of social housing retrofit solutions, according to client and users’ needs. A case study of the retrofit of a mid-terrace house is presented to demonstrate the workflow. The main output of the work is the BIM protocol, which can support client decision making in diverse social housing retrofit projects, considering all three elements (energy simulation, planning for reduced disruption and cost estimation) in an integrated fashion. Such an integrated approach enables clients to make better informed decisions considering diverse social housing retrofit options through a simple process using readily available BIM technology.

Legal requirements as well as life quality requirements demand to increase energy efficiency of existing buildings, that has been seen to represent a huge potential in energy savings, based on the size of the segment and the individual potential. The biggest challenges during the renovation of buildings occur when it comes to historic buildings where the facade cannot be modified to maintain its unique architectural appearance and integrity. Policy makers and building owners are facing “building energy efficiency versus heritage value” dilemma when on the one hand it is important to preserve a building’s architectural value and on the other hand, energy consumption should be reduced significantly. Internal insulation is one of the energy efficiency measures that can be applied. However, this is one of the most challenging and complex energy efficiency measures due to changes in boundary conditions and hygrothermal behaviour of walls, especially for buildings in cold climate Applying of interior insulation significantly modifies the hygrothermal performance of walls and, as a consequence, may induce a risk on interstitial condensation, frost damage, mould growth and other damage patterns. The behaviour of internally insulated wall strongly depends on the properties of the used materials. There is a need to develop new methods and guidelines for decision makers on how to implement energy efficiency measures in historic buildings. The aim of this Thesis is to offer safe and effective solutions for internal insulation systems of historic masonry buildings. To achieve this goal, the following tasks have been set: to perform historic construction material testing and analyse the test wall in a laboratory environment to determine the factors influencing the accumulation of moisture and the risks associated with it; to predict hygrothermal conditions of internally insulated masonry building using dynamic simulation program and to validate said models based on long term in-situ measurements in internally insulated case buildings; to estimate potential energy savings using dynamic simulation program. Several methods are combined within the research, including regression analysis, sensitivity analysis and heat and moisture transfer simulation validated by long-term in situ measurements.
