Abstract Poultry farming is one of energy intensive industries that consume large amount of energy to provide the suitable indoor environment for chicken health and production like meat and eggs. Currently, there are extensive researches and practices of applying renewable and sustainable energy technologies to poultry farming to achieve energy saving and carbon dioxide emission reduction. Therefore, it is worth to retrospect the state-of-the-art development and summarize the key features in this field. The main technologies include photovoltaic (PV), solar collector, hybrid PV/Thermal, thermal energy storage, ground/water/air sources heat pumps, lighting and radiant heating. It is found that up to 85% energy saving can be achieved by using these advanced technologies in comparison to the traditional poultry houses with a payback time of 3–8 years.

Poultry Farming

Poultry farming is one of high energy consumption and energy-intensive industries that requires significant amount of fuel fossil to provide the desired internal temperature for health and production level of chicken, which results in high running cost and growth of greenhouse gas (GHG) emissions. Renewable and sustainable energy technologies are being employed in the area of poultry farming in order to achieve energy saving, GHG emission reduction and to some extent supply potential selective benefits for farmers. Therefore, it is very necessary for generalizing the state-of-the-art technologies including the solar photovoltaic, solar photovoltaic/thermal, ventilation and wind turbine, air/water/ground sources heat pump and thermal energy storage. It is demonstrated that the system energy saving could achieve up to 85% with a payback time of 3–8 years, compared to the conventional heating system.

The objective of this research is to establish an appropriate operating strategy for a radiant floor heating system that additionally has an air source heat pump for providing convective air heating separately, leading to heating energy saving and thermal comfort in residential buildings. To determine the appropriate optimal operating ratio of each system taking charge of combined heating systems, the energy consumption of the entire system was drawn, and the adaptive floor surface temperature was reviewed based on international standards and literature on thermal comfort. For processing heating loads with radiant floor heating and air source heating systems, the heating capacity of radiant floor heating by 1 °C variation in floor temperature was calculated, and the remaining heating load was handled by the heating capacity of the convective air heating heat pump. Consequently, when the floor temperature was 25 °C, all heating loads were removed by radiant floor heating only. When handling all heating loads with the heat pump, 59.2% less energy was used compared with radiant floor heating only. Considering the local discomfort of the soles of the feet, the floor temperature is expected to be suitable at 22–23 °C, and 31.5–37.6% energy saving compared with those of radiant floor heating alone were confirmed.

District heating is seen as an important concept to decarbonize heating systems and meet climate mitigation goals. However, the decision related to where central heating is most viable is dependent on many different aspects, like heating densities or current heating structures. An urban energy simulation platform based on 3D building objects can improve the accuracy of energy demand calculation on building level, but lacks a system perspective. Energy system models help to find economically optimal solutions for entire energy systems, including the optimal amount of centrally supplied heat, but do not usually provide information on building level. Coupling both methods through a novel heating grid disaggregation algorithm, we propose a framework that does three things simultaneously: optimize energy systems that can comprise all demand sectors as well as sector coupling, assess the role of centralized heating in such optimized energy systems, and determine the layouts of supplying district heating grids with a spatial resolution on the street level. The algorithm is tested on two case studies; one, an urban city quarter, and the other, a rural town. In the urban city quarter, district heating is economically feasible in all scenarios. Using heat pumps in addition to CHPs increases the optimal amount of centrally supplied heat. In the rural quarter, central heat pumps guarantee the feasibility of district heating, while standalone CHPs are more expensive than decentral heating technologies.

In this paper, we perform a literature review on the current state of knowledge about homeowners in the context of the adoption of renewable heating systems. Despite a considerable number of studies about homeowners, homeowner–installer interactions, and ways to improve the effectiveness of renewable heating programs, based on homeowner knowledge, have not yet been studied in much detail. To address these knowledge gaps, we conduct a qualitative study on single-family house owners who installed heat pumps and took part in a renewable heating program in Geneva, Switzerland. We cover homeowner practices in choosing installers and heating system types, homeowners’ feedback about heat pump installation and use, as well as their experience in participation in the renewable heating program. Based on the literature review and the findings from the interviews, we provide the following recommendations on how to increase the effectiveness of renewable heating programs: (a) support for homeowners should not be limited to financial incentives; (b) partnership programs with installers could help to increase the quality of installation services and enable homeowners to choose qualified installers; and (c) assisting homeowners in pre-qualification and ex-post analysis, in learning how to operate their renewable heating systems and in solving problems during the post-installation period, can contribute to improved technology reputation, which can, in turn, increase technology uptake by other homeowners.

The literature suggests different approaches towards modelling of the environmental impact caused by the production processes. The present paper attempts to establish a framework for multicriteria comparison of agricultural sectors of the European Union Member States and identify the performance gaps in terms of energy-related carbon dioxide emission. The research relies on the two approaches, viz. the by-production approach and the multi-criteria decision making approach. The environmental performance indicators were evaluated in regards to the desirable output (gross value added), inputs, and the undesirable output (carbon dioxide emission). The results indicate that Slovakia, Estonia, Lithuania, and Hungary should attempt to improve their carbon factors by implementing cleaner energy technologies. The combinations of by-production sub-indices suggest that productivity gains are more important for Sweden, Belgium, Poland, and France. Czech Republic, Latvia, and Finland are specific with low performance in terms of both the intended production and the undesirable output. The MCDM approach identified similar trends in performance as suggested by country ranking and correlation analysis.

Poultry Farming

Backyard chicken farming is as an effective tool for poverty reduction in rural areas, by providing living to resource poor communities; it is an important source of extra cash income other than eggs and meat for family consumption. The present study was carried out to assess the role of backyard poultry farming in supplementing household economy of rural farmers dwelling in district Quetta, Pakistan. Information from ninety-nine randomly selected female backyard poultry farmers were gathered during November 2016 to March 2017. Owing to previous government and non-government interventions backyard poultry keeping was found as an established practice. Women were found the main custodian of backyard poultry birds and consequently were the main beneficiary of the activity. Poultry birds of Fayoumi and Golden / Rhode Island Red (RIR) breeds were the main types. Majority of the farmers reared these birds under scavenging conditions in combination with feeding on household left over dry bread (52%); most of the respondents (62%) were taking care of the birds by themselves which resulted in overall low production cost. Income included the earning received from sale of birds, eggs and the home consumption of poultry meat and eggs. Net income per annum per household was estimated as Pakistani Rupee (PKR) 79290/- (US$ 566). The estimated Rank Based Quotients (R.B.Q) based on farmers perception disclosed backyard poultry keeping as an important domestic source of meat and eggs with almost no or very little capital investment, ranked (I, 80%) followed by a substantial source of supplementary income and was ranked (II, 79%). Amongst the problems, disease outbreaks were the most prevailing problem (I, 90%) followed by unavailability of vaccines (II, 85%). The backyard poultry farming generated subsistence income and provided high quality valuable food that improved household nutrition.
