Economy Analysis

The article analyzes the concepts and indicators for assessing energy saving and energy efficiency, which revealed a clear terminological relationship between the studied concepts and the absence of evaluation criteria that characterize important components of energy efficiency by type of economic activity and economic spheres. The most important components of energy efficiency were identified and calculations confirming the importance of the national policy to improve the energy efficiency of the housing stock as the sector with the highest energy saving potential were made. It was confirmed that in order to achieve high indicators of real economic growth, both consistent and constructive measures are needed to create energy facilities of a new formation, as well as to improve existing capacities and facilities, for example, in the form of major repairs of the housing stock.

Integrated Estimation

Ensuring the energy efficiency functioning of housing and communal services and increasing the energy efficiency of Ukraine's housing stock, which is one of the largest consumers of heat energy, requires the search for potential opportunities for managing energy efficiency of buildings. Integration into the world economy obliges Ukraine to adhere to international economic principles, one of which is the growth of energy efficiency.The article examines the experience of the world countries in the field of energy efficiency of buildings on the basis of sustainable building concept.  The methodology of calculating the integral rating point of the regions of the country based on their energy saving potential is developed. It can be used to evaluate the potential of energy efficiency management of buildings in Ukraine. As a result of the calculations of the integrated estimation of the energy saving potential, an appropriate ranking and grouping of the regions of Ukraine has been carried out.Improvement of the organizational and technical potential of providing energy-efficient functioning of the housing and communal services of Ukraine and the introduction of effective mechanisms for its modernization on the basis of the sustainable building concept should ensure an increase in the efficiency of energy efficiency management of buildings.

New Buildings

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?

Air conditioning and refrigeration equipment are more and more widely applied, It’s energy efficiency proportion of total energy consumption is growing. To evaluate energy efficiency and apply high grade energy efficiency of air conditioning , that can bring considerable economic benefits and improve energy-saving initiative for the enterprises. This has great practical significance to realize Chinese energy-saving task. In this paper the air conditioning energy efficiency ratio(EER), seasonal energy efficiency ratio(SEER) and integrated part load value(IPLV) are proposed and analyzed, Many evalution methods are put forword to provide appropriate evaluation criteria for enterprise, and the energy-saving measures on the different assessment criteria are also put forward, It has some guiding significance to improve the efficiency of air conditioning and refrigeration equipment.

Existing Housing

The existing housing stock has a major energy saving potential and is mostly considered to be the sector in which energy efficiency most cost effectively can be achieved. About 30% of all energy use is consumed in the housing stock. The European union formulates saving targets, policies and regulations that have to be implemented by the member states and a considerable share of the EU budget for research and innovation is dedicated to this challenge. In recent years many policies, investment programmes, technical innovations and process innovations have been developed and been put into practice. However, it appears to be very difficult to realise massive renovation programmes in the existing housing stock and really make a step forward towards the energy efficiency goals. This special issue presents an overview of actual insights of the perspectives of energy efficiency in the housing stock based on several research projects and analyses and discussions about how the current policies will work out and which are the barriers that still have to be taken. We focus on the policies, the processes and the people.

Consumption Intensity

This article proposes using passenger transportation energy intensity to measure the energy utility efficiency and energy-saving potential of the passenger transportation, uses the complete decomposition model to decompose the passenger transportation energy intensity from 1990 to 2007, and then investigate how various factors impact passenger transportation energy intensity. As is shown in the results, transportation structure increases passenger transportation energy intensity, while energy efficiency decreases it, however the decline is limited. Thus energy saving caused by adjustment of transportation structure is much more considerable.

This study evaluates energy efficiency of pastoral (PDFs) and barn (BDFs) dairy farming systems in New Zealand through application of data envelopment analysis (DEA) approach. Two models constant return to scale (CCR) and variable return to scale (BCC) of DEA were employed for determining the technical (TE), pure technical (PTE) and scale (SE) efficiencies of New Zealand pastoral and barn dairy systems. Further, benchmarking was also performed to separate efficient and inefficient dairy farms and energy saving potential was identified for both dairy systems based upon their optimal energy consumption. For this study, the energy inputs data were taken from 50 dairy farms (including PDFs and BDFs) across Canterbury, New Zealand. The results indicated that the average technical, pure technical and scale efficiencies of pastoral (PDFs) dairy systems were 0.84, 0.90, 0.93 and for barn (BDFs) systems were 0.78, 0.84, 0.92, respectively, showing that energy efficiency is slightly better in PDFs system than the BDFs. From the total number of dairy farms 40% and 48% were efficient based on the constant return to scale and variable return to scale models, respectively. Further, the energy saving potential for PDFs and BDFs dairy systems through optimal energy consumption were identified as 23% and 35%, respectively. Thus, energy auditing, use of renewable energy and precision agricultural technology were recommended for energy efficiency improvement in both dairy systems.
