“…The results in Paper III display a wide range of objectives regarding energy efficiency, with different terminology use (or ways of measuring efficiency), target levels, and years of fulfilment [33]. Furthermore, as Paper V suggests, energy efficiency appears to be emphasized more in the organizations' agendas today compared to 2010 [35]. To further analyze an increased implementation of energy efficiency measures, it is important to address the progress and development of barriers to and drivers for energy efficiency, as in the appended Papers IV and V.…”

Despite the need for increased energy efficiency in the residential and service sector, cost-efficient energy conservation measures are not always implemented. This is explained by the existence of barriers to energy efficiency. By using surveys, the perception of barriers and drivers for energy efficiency in the Swedish residential and service sector is studied, together with changes in the perception of barriers and drivers during the 2010s. The perception of a lack of time or other priorities is the most hindering factor for implementing energy efficiency measures, along with the experience of a slim organization. On the other hand, the major drivers are reducing costs, followed by drivers of an organizational or behavioral nature. The results illustrate a challenging situation among publicly owned organizations, small organizations, and those in rural areas, as -relative to other groups -they experience barriers to a greater degree and drivers to a lesser extent. Positive factors that emerge between 2010 and 2020 are that energy strategies are integrated, and energy efficiency is given high priority throughout the organizations' working methods. Lastly, by using simulation and optimization model, energy end-use measures of (1) large-scale renovation of a multifamily building stock and (2) the use a hydronic pavement system for snow and ice clearance are studied. These are analyzed in terms of energy performance and GHG emissions based on different system boundaries. The results regarding the large-scale renovation of multifamily buildings reveal a potential conflict. The measure resulting in the best energy performance of the building, which may be the most desirable measure from a building owner's perspective, risks leading to larger greenhouse gas emissions. The conflict arises due to different use of system boundaries. A hydronic pavement system -a rarely used application in present-day district heating systems -proves to be a possible sustainable solution and a suitable application for the future generation of a low-temperature district heating system. The results underline the importance of understanding system boundaries in general, but also when considering energy efficiency improvements. An overly narrow system perspective and boundaries can lead to unwanted sub-optimizations, with higher greenhouse gas emissions as a consequence. hydronic pavement system. A hydronic pavement system can use low-grade temperature heat carriers, such as the return water in a DHC system. A hydronic pavement system consists of embedded pipes in the pavement structure, where heat is transported by circulating water or other heat media. The objective is to prevent snow and ice formation that may cause slipperiness during winter periods. In Sweden, the use of hydronic pavement systems accounts for an annual district heating use of , making this a little used application but with promise for development.

“…Therefore, it is crucial to interpret our results with caution. There are additional factors that could influence the barriers to and drivers of EEMs, including variables like the level of urbanisation and regional climate variations [ 53 ]. However, due to constraints in available data, we did not investigate these aspects in our study.…”

“…Many elements can cause renovations to fail to deliver the expected energy reductions and thus block further improvements from being developed, until the next renovation cycle, phenomenon also known as the lock-in effect. For example, the energy -efficiency gap, where potential improvements to redirect energy demand appear to be cost-effective energy -efficiency technologies but are not the optimal solution [16]. Because of this, it is important to be aware of the uncertainties and risks that cause gaps and to take action to prevent them.…”

The renovation of residential stock is one of the most promising areas, in terms of energy reduction, because these buildings are highly inefficient and represent the largest part of the building stock. However, the environmental impact assessment over the life cycle of building renovation is rare. It is more common to develop an assessment for new buildings. This study presents a method that combines the evaluation of the benefits of renovating residential buildings, considering cost, energy and environmental benefits using Life Cycle Assessment (LCA). The method is based on 3 stages of development. First, the database of energy certificates, costs and LCA was analysed. The second step is to develop a workflow in Rhino/Grasshopper/E-Plus to automatically model a residential building and feed the simulation model with the data obtained from the databases. Finally, a simulation campaign was carried out to obtain an optimal renovation package, minimising energy consumption and environmental impact. The research was carried out in a case study in Uddevalla, Sweden. The residential building has different measurements including energy consumption data before and after renovation. This was used to validate the proposed methodology. The validation shows that accurate results are achievable with potential for mass application.
