The energy saving potential of the building stock is large and considered to be the most cost efficient to contribute to the CO2 reduction ambitions. Severe governmental policies steering on reducing the energy use seem essential to stimulate and enforce the improvement of the energy performance of buildings with a focus on reducing the heating and cooling energy demand. In Europe the Energy Performance of Buildings Directive is a driving force for member states to develop and strengthen energy performance regulations for new buildings and energy certificates for the building stock. The goals are to build net zero energy new buildings in 2020 and to reach a neutral energy situation in the whole stock by 2050. More and more research projects deliver insight that the expected impact of stricter regulations for newly built houses is limited and the actual effects of energy savings through housing renovations stay behind the expectations. Theoretical energy use calculated on base of the design standard for new houses and assessment standards for Energy Performance Certificates of existing dwellings differ largely from the measured actual energy use. The paper uses the findings of some Post Occupancy Evaluation research projects. Is the energy saving potential of the housing stock smaller than expected and should we therefore change the policies?

The City

The aim of the research project was to develop a City Energy Audit (CEA) for Lublin, Poland. CEA collects information on the built environment and city infrastructure in a systematic way, and provides structural analyses with special focus on housing stock. The purpose of CEA is to provide reliable input for analysing current and future energy consumption patterns, i.e. the basis for planning effective and viable energy saving measures at urban level. The CEA’s fitness for purpose was confirmed in practice – it was used by the local authorities in the process of preparing the Study of the conditions and directions of spatial planning for the City of Lublin in September 2011. To present the idea of applying CEA, the authors use their original template of Possible Retrofit/Repair and Energy Saving Measures (further referred to as MDN/R+E) and develop it into detailed solutions using the example of an 11-storey prefabricated block of flats.

The article discusses the main aspects of the Federal program of energy saving and energy efficiency of the housing and communal complex. The algorithm of energy survey of the building is given. The calculation of the temperature field of structural units using the ELCUT software package is considered. The operational risks of implementing the energy saving Program and improving the energy efficiency of the housing stock are determined.

PurposeMany studies on policy implementation have emphasized the difficulties of putting policies into practice. This paper presents several ways in which Dutch social landlords incorporate their energy saving policies in their “regular” housing management, such as planned preventive maintenance, renovations and other physical improvements.Design/methodology/approachSeveral housing associations were selected that have formulated an energy saving policy and that have at least some experience in implementing these policies into projects. Interviews were held with managers of asset and maintenance management and with policy staff of housing associations. The extent to which the policy ambitions, both at the portfolio level and at the project level are carried out, and in which way these ambitions are embedded in the organisations’ regular working processes are investigated. Also, the main stimuli and barriers for the implementation of the energy saving policies are identified. Special attention has been paid to the feasibility of combining of energy saving measures with other physical improvements in the housing stock.FindingsResults show that the implementation of energy saving policies in annual improvement and maintenance plans is in most cases not problematic, and that the most significant problems arise during the realisation of the policies in the preparation of specific investment projects.Research limitations/implicationsEnergy saving policies are relatively new to the sector in The Netherlands. Therefore, the number of case studies is relatively low.Originality/valueThe paper offers case studies which illustrate and explain the gap between energy saving policies and realisation of these policies.

Concrete Plate

Managers of large housing estates whose stocks consist mainly of precast concrete plate buildings of 1970ies, due to their sheer size and technical condition far from being perfect, are especially concerned with searching for solutions that would reduce energy consumption. Thermal modernization projects provide an opportunity to adopt a holistic approach to the problem of obsolescence of this relatively new housing stock and to consider it in terms of urban regeneration. The paper describes the energy saving policies in Poland and results of pilot studies of Building Research Institute (ITB) aimed at defining optimal scope of thermomodernization of precast concrete plate housing. The paper investigates into the effects of thermomodernization of a particular, though typical, housing estate in Lublin in order to give grounds for future actions in the field of energy saving measures.
