Energy efficiency sometimes is considered to be an easy solution for achieving immediate energy savings. Efficient technical solutions are available already today for most applications and uses. Technological developments are offering and will offer in the future a range of technical solutions for improving energy efficiency, but there are barriers: organizational, financial and behavioral which need to be addressed holistically.

The ambitious goals for energy efficiency are reaching beyond purely technical solutions and go much further in terms of cost-effectiveness, financing, acceptance, innovation, and environmental impact assessment. Cost-effectiveness of technical solutions: the profitability of investing in energy efficiency technologies are often unknown or questioned. Financing: energy efficiency requires a long-term commitment, and the financing framework should take this into account. Innovation: technology roadmaps can be useful tools for the design of possible futures and help householders to agree on short-term solutions. Environmental impact assessment: using energy-efficient technologies should be based on a full life-cycle analysis, and be realistic and achievable.

WINERGY helps householders meet energy-efficient technologies and products hence enabling householders to cut energy bills and reduce carbon emission to the environment. By doing this, WINERGY presents personalized and home-specific technologies to householders. Through the instrument of Analytic Tool, we take personalized information about the energy efficiency of any type of house. So, the cost-effectiveness of technical solutions, innovative developments in technical solutions, environmental impact assessment and even financial condition of householders are included in the process of presenting energy efficiency technologies to householders.
