ELISA Tool : Life Cycle Analysis for Solar Cooling Systems
ELISA Tool : Life Cycle Analysis for Solar Cooling Systems
February 2019
Publisher: Task 53

Another Excel-based tool is the Environmental Life Cycle Impacts of Solar Air-conditioning Systems (ELISA). This user-friendly Life Cycle Assessment (LCA) tool can assist researchers, designers, and decision makers in evaluating the life cycle energy and environmental advantages for solar cooling systems in place of conventional ones. This easy to use tool, designed for educational and research activities, takes into consideration specific climatic conditions and building loads.

ELISA Tool

ELISA was developed by the University of Palermo to carry out simplified LCAs and to compare SHC systems with conventional systems. It can:

  • Be used for different geographic contexts
  • Compare up to 4 typologies of systems:
  1. SHC system
  2. SHC system with photovoltaic panels (PVs)
  3. Conventional systems
  4. Conventional systems with PVs
  • Calculate for:
  1. Global warming potential (GWP)
  2. Global energy requirement (GER)
  3. Energy payback time (EPT)
  4. GWP payback time (GWP-PT)
  5. Energy return ratio (ERR)

T53E4 Tool – To Assess a System’s Technical and Economic Potential
February 2019
Publisher: Task 53

T53E4, a technical and economic assessment tool, rates and benchmarks new developments at the system level (proper design and operation). This assessment tool provides a comprehensive database of boundary conditions that are used in various configurations and applications, which means that tool users can assess entirely different types of configurations. Users can obtain information on the efficiency and cost of a solar heating and cooling (SHC) installation and the reference system in a common comparable format. As part of this work, the Task researchers assessed and benchmarked 28 solar heating and cooling systems with the cooling capacity ranging from 5 kW to more than 150 kW.

The tool’s reference system consists of a natural gas boiler and an air-cooled vapor compression chiller. All key results are provided in a normalized form. This means that a specific reference was selected to avoid a discussion about the absolute values and the right choice of boundary conditions.

T53E4 Tool

Results of analyses using the T53E4 tool: The cost ratio is shown on the y-axis over the non-renewable primary energy savings fsav PER-NRE on the x-axis. The graph on the left shows the configurations at southern sites, where cooling demand dominates over the summer. The graph on the right shows results from northern locations, where the need for cooling is lower during the same period

Two main parameters were calculated from the monthly energy balance of each configuration: • The non-renewable primary energy savings (fsav PER-NRE), which compares the non-renewable primary energy demand of an SHC system to those by a reference system. The fsav ranges from 0.3 to 0.94, which means that solar energy replaces 30% to 94% of non-renewable primary energy demand of the reference system.

The cost ratio (CR) to describe the levelized cost of energy (LCOE) of an SHC system as opposed to the LCOE of a reference installation. The LCOE is derived from annuities paid over the lifetime of a system (typically 25 years). A CR below 1, such as 0.8, indicates that the solar device offers a 20% reduction in costs compared to the baseline, while a CR above 1, such as 1.4, describes a system that raises costs by 40%.

The configurations were then grouped by boundary conditions, for example, whether the location is in the south or north, and identified separate lines for solar heat and PV. Northern installations consist of those in Austria, Finland, Germany, Sweden, and Switzerland. Sites in the south are found in Italy, Spain, France, and China. The southern locations depicted on the left graph below show promising results, with between 40% and 70% of energy savings at a total cost lower than that of the reference systems. This amount of saving is possible for both PV (see dotted line) and solar heat (see continuous line). If the industry could offer reduced system costs by only 15%, energy savings could be as high as 80% and the units would be cost competitive in southern locations.

The cooling systems in northern locations, where there is less demand for air conditioning (graph on the right-hand side above), paint an entirely different picture. Only if primary energy savings are kept to 40% systems can be cost-competitive to references. Aiming for savings of between 60% and 80% will increase costs tremendously. Again, it is the investment that had the strongest impact of all parameters. If investment costs are reduced by at least 30%, cost-effectiveness could be guaranteed along the entire trendline.

What this tool shows is that cost-competitive solar cooling configurations are possible even with today’s investment cost models. And, that solar technologies can be optimized for solar heating and cooling. Whether solar thermal or PV is the more favorable option will mostly depend on the location and the design of the system.

Heat accounts for more than half of global final energy consumption. However, heat production remains heavily fossil-fuel based and is a significant contributor to CO2 emissions, accounting for 39% of total annual energy-related emissions globally. To achieve the ambitious targets of the Paris climate change agreement, heat decarbonization is a must. But what role can solar thermal play?

June 2016. The International Energy Agency, Solar Heating and Cooling Programme (IEA SHC) released the 2016 edition of its report on the global status of the solar thermal heating and cooling market. As the 2014 solar thermal market felt the impact of slowing markets in China and Europe, the largest world markets, growth was seen in two important areas – large-scale solar thermal systems and solar heat in industrial processes. And, solar heating and cooling still remains by far the solar technology with the largest total capacity (435 GWth) compared to PV (227 GWth) and solar thermal power (5 GWth).

Publisher: IEA SHC
This is an update of the April 2009 Solar Update article. The objective of the 2009 article was to put in perspective the potential of often-cited nuclear and renewable alternatives to Greenhouse Gas (GHG) emitting fossil energy sources. Its main conclusion was that although a mix of alternatives, including hydropower, biomass/biofuels, geothermal, ocean thermal energy conversion, waves, tides, wind and solar, appeared like a sound approach to bringing about the desired economically and environmentally sustainable energy future (akin to putting future energy eggs in different baskets), a review of their potential clearly showed that the solar resource dwarfed all other renewables (and fossil/nuclear alike) by orders of magnitude. And therefore, the desired economically and environmentally sustainable energy mix of the future should be essentially solar-based.

Solar heating and cooling (SHC) can provide low-carbon emission energy from solar resources that are widespread throughout the world. SHC describes a wide range of technologies, from mature domestic hot water heaters to those just entering the demonstration phase, such as solar thermally driven cooling. This roadmap envisages development and deployment of solar heating and cooling by 2050 to produce 16.5 EJ (4 583 TWhth; 394 Mtoe) solar heating annually, more than 16% of total final energy use for low temperature heat, and 1.5 EJ solar cooling, nearly 17% of total energy use for cooling by that time.
