Viitekehys ja metodologiat lähes nZEB-korjausrakentamisen edistämiseksi Suomessa

The emerging trends for deep retrofit of existing buildings in Europe require the formulation of strategies for nearly zero-energy buildings (nZEBs) and achieving benchmarks as outlined in the Energy Performance of Buildings Directive (EPBD) recast. The fundamental process of retrofitting to an explicit high performance necessitates the development of robust and diverse methodologies to be used during the early stages of planning in retrofit projects. The construction sector lacks the extensive use of such methods for early decision-making that are essential to accelerate building renovation in Europe. "Perhaps literature suggests that the huge mismatch between the predicted and measured performance, referred to as the 'Performance Gap ". The most prominent causes of this uncertainty of energy performance savings as identified in the literature are; specification uncertainty in building modelling, poor practice in operation, lack of proper knowledge and skills in the construction industry, facility managers, etc. Low carbon building energy technologies for low carbon generation are diverse. People's adoption of low carbon buildings increases the use of different types of renewables, and each technology utilizes various natural resources in a variety of ways, with economic, social, and environmental impacts. Thus, it is important to evaluate the social acceptance of low carbon buildings to understand people's perceptions regarding their usage and the challenges posed by climate change. The role of key stakeholders in the industry becomes highly responsible for achieving the energy performance targets. Thus, this research presents the application of combined i) research techniques and ii) building simulation and optimization strategies that shall support the decision making in retrofitting buildings to low-energy, Nearly zero energy, and comfortable buildings. The findings of this research can provide classical knowledge in many ways. For example, (1) they provide us with a new approach to know how and what kind of steps have already been taken to create awareness about low carbon building energy technology and climate change so far in Finland, and (2) they help us to analyse public perceptions towards low carbon building applicability and to acquire knowledge about what different kinds of low carbon building energy technologies they (participants) are aware of. 3) Attitudes and approaches of the stakeholders towards nearly zero energy buildings (nZEBs).
