Biography [eng]

My research focus is to identify sustainable technologies based on results from energy and material flow analyses and to understand their diffusion through the application of systems of innovation concept and sociological and marketing theories. I have researched on a wide range of topics including diffusion of multi-storey wooden buildings, attitudes and perceptions towards adoption of space heating systems and building envelop energy efficiency measures in residential buildings, one-stop-shop business models for energy efficiency renovation of detached houses, stakeholder attitude towards intensive forest management practices, and factors contributing to tropical deforestation.

Abstract [en]

The selection of the most appropriate window and blind design is a challenging task due to the existence of potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. Resolving these conflicts relies on a trade-off window and blind design. This research applied a decision-making framework to select a trade-off window and blind design for an office room in Sweden. The decision-making framework was developed based on integrating the non-dominated sorting genetic algorithm-II and the analytical hierarchy process. The first step in the application of the framework was to generate a model of the office room using EnergyPlus. Six types of window and four types of blind; an internal venetian blind, an internal roller curtain, an external venetian blind and an external overhang panel, were modelled in EnergyPlus. The second step was to run an optimisation using non-dominated sorting genetic algorithm-II. For this purpose, various window and blind design variables were specified in modeFRONTIER platform. The third and last step in the application of the decision-making framework was to select a trade-off window and blind design using analytical hierarchy process. The results show the strength of the decision-making framework in selecting a trade-off design, and thereby the ability to resolve conflicts through intelligent use of simulation in analyzing big-data in built environment, energy and cost sectors. Since, the computation and processing power for performing simulations is constantly increasing, architects and designers can exploit the decision-making framework and locate a trade-off design in a relatively short period of time.

Abstract [en]

Existing studies of heating products have analyzed the adoption of energy-efficient heating technologies from diverse micro and macroeconomic aspects, such as diffusion of innovation, willingness to pay, business models, energy pricing, etc., but the analysis from a marketing management approach based on end customer insight is still lacking. Understanding the decision-making process of end customers, and the influence of social environment at the diverse stages of the purchase process leads to a focused market strategy, thereby contributes toward overcoming the multi-level segmentation challenge faced by the manufacturers of heating products. In this context, a two-step exploratory research was conducted in December 2013 with end customers of the residential heat market in Hungary. The end customers were found to be active decision-makers engaged in deliberate planning in the purchase of heating products. They start searching for information by turning mainly to online information sources and they actively integrate their social network in all stages of the decision-making process, which means that the role of the installer is relatively less influential along the whole purchasing process. Identified influencing communication channels at the diverse stages of the purchase process may support manufacturers to develop a user-centric marketing strategy by optimizing the communication instruments in their marketing mix by, for instance, including direct end customer communication via online channels and by de-emphasizing offline communication channels.

Abstract [en]

Swedish government adopted national targets to reduce total energy consumption and mitigate environmental impacts. At this point, detached houses play an important role, since they account for a large share of dwelling stock in this country. The majority of these buildings are affected by technical deteriorations in building envelopes and heating, ventilation and air condition systems. Accordingly, there is a need for a deep renovation strategy, which covers both energy efficiency measures and economic issues. Additionally, a deep renovation can improve indoor climate, which contributes to the enhanced health and wellbeing. Thus, the aim of this study is to compare the efficiency of eight different renovation packages in reducing energy consumption and providing economic benefits in a detached house in Sweden. The renovation packages include 1) improving the U-value of building envelopes; 2) adding a heat recovery for ventilation system; 3) installing a ground source heat pomp for supporting heat demand and domestic hot water; 4) combination of renovation package 1 and 2; 5) combination of renovation package 1 and 3; 6) combination of renovation package 2 and 3; 7) combination of renovation package 1, 2 and 3; and 8) combination of renovation package 1, 2, 3 along with installing photovoltaic cells for producing electricity. The reduction in energy consumption was calculated in kWh/m². year for each renovation package, while the economic benefit was obtained by calculating the payback period during a lifespan of 50 years and internal rate of return with interest rates of 1%, 3% and 6%. The results indicate that renovation package 8 has the highest potential in reducing total energy consumption, while renovation package 3 is the most profitable solution since it provides the shortest payback period with the highest internal rate of return. The results help to define and project efficient energy policies in Sweden.

Abstract [en]

The building sector is responsible for more than 40 % of the energy use and 32 % of carbon dioxide emissions in the European Union (EU). Previous research has shown that the present rate of energy retrofit and refurbishment in Europe is far below (<50 %) than that is required to meet the EU's building related energy efficiency goals for 2020. Appropriate policy interventions for deep renovation is perceived as a catalytic agent in promoting energy efficiency and leveraging more investments in the building sector. EU directives regarding Energy Efficiency reflects in various member states' national targets and policy measures to improve the energy performance of the existing building stocks. Economic policy instruments seem to be influential in steering the deep renovation market, but this alone may not be sufficient for the sustainable growth of the market. There is a need for market-based approach to enhance the private sector involvement, both in terms of technical and financial capabilities. This paper evaluates the policy instrument used for promoting deep renovation of residential buildings in the Netherlands. A "Theory-based evaluation" technique has been used in analyzing the content of the policy instrument, and the underlying theories and policies, at output and impact level. A set of the evaluation criteria have been applied for assessing such policy instruments in leveraging energy efficiency investments and their effectiveness in terms of energy savings. The assessments are done based on the meta-analysis of relevant literature and data sources, and finalized in consultation with the Dutch partners from INNOVATE (Integrated solutions for ambitious energy refurbishment of private housing) project under Horizon 2020. Further, the challenges for scaling up such existing effort for the sustainable growth of the deep renovation market has been explored.

Abstract [en]

Windows and blinds play a significant role in both shaping energy consumption and enhancing indoor comfort. But there are still difficulties with selecting windows and blinds due to the existence of potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. A literature review was conducted with the purpose of developing a decision-making framework that resolves the conflicts, and allows selecting a window and blind design based on trade-off between visual comfort, thermal comfort, energy consumption and life cycle cost. The decision-making framework was developed by integrating non-dominated sorting genetic algorithm-II as an optimisation algorithm with analytical hierarchy process as a multi-criteria decision-making method. The optimisation algorithm considers different window and blind design variables and analyses multiple designs, while the multi-criteria decision-making method ranks the optimization results and selects a trade-off design. An operating package enabled the decision-making framework to be automated. The operating package was obtained by coupling EnergyPlus as a simulation tool and modeFRONTIER as an integration platform. The decision-making framework was developed to select a trade-off window and blind design through intelligent use of simulation in analysing big-data in built environment, energy and cost sectors. Application of the framework ensures the minimum visual and thermal comfort thresholds with the lowest energy demand and cost. Architects and designers can use the framework during the design or renovation phase of residential and commercial buildings.

Abstract [en]

This paper examines the views of construction SMEs in Sweden regarding innovations, in particular the one-stop-shop business concept,and its adoption for renovation of detached house. The investigation is based on interviews with 10 construction SMEs and by applying aconceptual framework for organizational innovation adoption. The results suggest that, even though the one-stop-shop businessconcept is perceived as a means for growth, at present, construction SMEs in Sweden are unlikely to adopt it at present. This lackof interest is mostly related to the perceived complexity of this model and the underlying risks and uncertainties. That complexity isseen as a preventing factor as it puts at stake their current business. The interviewees proposed that there should be an entrepreneur to coordinate the actors involved in the renovation process, whose role can be further studied.

Abstract [en]

In this paper, we identify the socio-economic attributes and attitudes that have influencedhouse owners in renovating their homes in the past. Our study is based on responses to an onlinequestionnaire survey of 971 house owners living in Kronoberg County in Sweden. Results showedthat the interest and willingness of the house owners to perform a renovation varied dependingon their demographic background and the age of the house. The latter positively affected pastrenovations, only when combined with the residence time. Furthermore, the age of house ownersstrongly and positively affected the probability of performing aesthetic type of renovations, becauseof a long time of residence in the house. Younger, town living, and highly educated house ownersseem to be more concerned regarding saving energy, which motivated them to perform physicalrenovations on their house. Our results also suggest that income, level of education, and place ofresidence have an effect on renovation decisions only through their effect on the energy concern ofhouse owners, and a varied effect on renovation decisions, when combined with the time of residencein the house.

Abstract [en]

The majority of single-family houses in Sweden are affected by deteriorations in building envelopes as well as heating, ventilation and air conditioning systems, since they are about 30 years old. Theses house are therefore in need of extensive renovation, which provides an excellent opportunity to incorporate energy efficiency measures to reduce both the energy consumption and also operational. Although former studies analyzed the cost effectiveness of various renovation packages, they mainly excluded the evaluation of energy price implications on cost effectiveness of different renovation package in Sweden. Accordingly, this study considers three energy prices and quantifies the payback period (PBP) and internal rate of return (IRR) of the packages, when renovating a single-family house in Sweden. The renovation packages included three distinct energy supply systems, commonly installed when implementing energy renovations: ground source heat pump (GSHP), photovoltaic solar panels (PV), and an integrated GSHP and PV system. The analyses of results show that a the GSHP system provides higher IRR and the lowest PBP compared to the other two renovation packages, due to its high performance in reducing energy consumption and its relatively low investment cost. Furthermore, results show that raising the energy price can increase the IRR and reduce the PBP of the renovation packages and respectively. Moreover, increasing the interest rate adds on PBP of renovation packages, since it depreciates the cost for saved energy.

Abstract [en]

Based on an online survey, this paper analyzes the attitude of house owners in Sweden towards future renovations and one-stop-shop (OSS) services for deep renovation of detached houses. With the aid of a house owners’ decision-making journey for renovation, personal and contextual variables have been analyzed to identify those house owners having renovation plans in the near future, what they are going to renovate, and which needs led them to that decision. Furthermore, we examine if there is an interest in OSS concept. Results suggest that deep renovation is not yet prioritized. The priority for house owners is to change specific components of their dwelling and follow a step-wise approach. Aesthetic renovations are high on the agenda, with some structural and energy-related renovations following them. House owners between 29- 49 years of age could be the customer segment to target for deep renovations. The OSS concept seems interesting to a number of house owners, who can form an early adopters segment that could develop the market. There is a need for a cost-efficient OSS concept for deep renovations, ensuring the quality of work, and the optimization of financial products and tax incentives to accelerate the deep renovation market.

Abstract [en]

To address the renovation needs of detached house stock in Sweden, micro and small-sized enterprises (MSEs), a subgroup of small and medium-sized enterprises, are expected to introduce more comprehensive house renovation solutions. One-stop-shop (OSS) is an innovative Product-Service System model that can enable MSEs to offer comprehensive renovation packages instead of existing fragmented solutions. We have applied a conceptual framework for innovation adoption in organizations and conducted an interview of 21 construction MSEs in three different geographical areas in Sweden to examine their perceptions and preparedness to adopt the OSS business concept. Findings showed that the examined MSEs are positive towards OSS as it could address the needs for the comprehensive renovation of detached houses. However, presently, are not prepared to take the coordinator’s role in such a concept mainly due to the perceived business risks, the lack of flexibility to organizational restructuring, and lack of resources and management competency to coordinate multiple tasks and actors. Those organizations lacked awareness of existing policy support and access to funding mechanisms to try new business models. As a solution, they proposed an external coordinator to be the provider of OSS, on the trial phase, whose role and characteristics need to be further examined.
