Changes in awareness and attitudes
Those targeted by the programme recognize that their knowledge and attitudes toward EE options and opportunities has changed after the programme.
Adoption of energy-saving behaviours
Those targeted by the program decide to adopt energy savings practices such us switching off the lights more often, using less water, or following specific instructions.
Uptake of the technology
Beneficiaries of the programme decide to act and uptake a certain technology.
Upgrade of the efficient technology
Decision by the beneficiaries of the programme to act and upgrade a certain technology.
Usage of the technology (once received)
Measurement of usage of the technology after it has been received (for examples disseminated by an organisation, or purchased by the beneficiaries).
Energy net savings or consumption
Net energy or demand savings refer to the portion of gross savings that is attributable to the programme. This involves separating out impacts that are a result of other influences, such as consumer self-motivation.
Energy security or access
Energy security is intended as the uninterrupted availability of energy sources at an affordable price. In this context, an EE intervention might have increased energy security by reducing the energy costs due to more efficiency technologies, for example.
Water consumption
Net water consumption deriving from the EE intervention.
Air quality index or pollutions rates
Air pollution or greenhouse gases that would have been emitted if more energy had been consumed in the absence of the energy efficiency program. These emissions can be from the combustion of fuels at an electrical power plant or from the combustion of heating fuels, such as natural gas and fuel oil, at a project site.
Income savings
Increased economic savings due to more efficient new/upgraded equipment or changing energy savings behaviours.
Job creation
New job creation due to the installation of new equipment or adoption of innovative practices that require more expert personnel or simply additional workers.
Building stock value
Increased property value due to the installation of new equipment/ renovation.
Health status comfort and wellbeing
Health status, comfort and wellbeing due to energy efficiency interventions.
GHG-emissions
Carbon related emissions (CO2) and non carbon related emissions i.e. methane (CH4), nitrous oxide (N2O) and fluorinated gases
Codes or standards with enforcement mechanisms policies
The introduction of EE standards, for example, in the construction or renovation of buildings/houses to make them energy efficient, (i.e. building energy codes which are a subset of building codes, that establish baseline requirements and govern building construction to ensure energy efficiency).
Utility-based programmes
Utility based programmes, are also called Energy Efficiency Obligations, Energy Savings Obligations and White Certificates. These mechanisms place obligations on utilities to find energy savings equivalent to a certain percentage of their energy sales; depending on the program design, utilities can invest in end-use efficiency with their customers, or purchase energy savings from third parties. Some schemes also allow for trading of the energy savings. (Denysenko et al. 2018).
Disclosure policies
Disclosure policies seek to reduce information asymmetries between building owners and prospective investors or renters so that this information can factor into decision-making processes (Kontokosta et al. 2020). Disclosure laws improve, for example, consumers’ awareness of the energy use of homes and buildings, which can have a significant impact on its economic value.
Other overarching EE legal framework
Any type of law or policy framework that encourages users to adopt energy efficiency technologies/services.
Bank lending (credit lines and guarantees)
Credit lines or green mortgages from local banks to support EE investments. They can be, for example, support the portfolio of EE smaller investments, or increase the energy efficiency of production process in factories/businesses/SMEs. Examples of this are: - renovation of existing housing stock to adapt it to better preserve the temperature over different types of weather reducing the amount of energy to heat or cool the building/house (i.e. weatherization interventions, insulation, retrofit), or
-energy efficient improvements in industrial facilities (i.e. interventions to increase the efficiency of factories' power plants by upgrading old ones, or replacing them with more efficient models);
-upgrades of energy transmission systems to reduce the leakages and waste of energy.
Subsidies or monetary incentives
Subsidies/monetary incentives (i.e. cash transfer) to uptake energy efficiency technologies/behaviours. For example, renovations, weatherisation, or purchases of more EE efficient technologies.
Residential home appliance credit
Private or public credit lines for households to purchase more EE appliances.
Energy pricing incentives
Interventions to change the energy price inducing reduction of energy consumption. This can be, for example, based on time-of use (TOU) pricing, aimed at reducing the energy consumption in peak hours. Another example is prepaid electricity meters.
Equipment leasing for EE technologies
Leasing schemes to adopt more efficient technologies, especially in the industrial sector.
Education and campaigns
Contagion processes such as education, communication campaigns, or peer comparison to nudge people to change their behaviours and practices for energy consumption. This could be delivered for instance, by flyers or face-to-face discussions to explain to consumers how to reduce their energy consumption by changing their behaviours and/or adopting a certain technology or service (i.e. pre-commitment and simplified information highlighting the new technology/practice benefits).
Monitoring and displaying energy consumption
Interventions that provide households with their energy consumptions records inducing them to use less energy. Some examples are home energy reports, feedback, and smart meters delivered to the household (i.e. Power program).
Capacity building
Interventions to build people’s or communities’ capacity (including local authorities) to understand, implement, and use the energy efficient technologies, services, practices and behaviors by, for example, delivering training, workshops (i.e. training associated with the introduction of an energy efficient technology).
Energy audits
Energy audit requirements aim to improve building owners’ awareness of cost-effective EE technologies opportunities.
Provision of EE technology/ services
Direct provision by public/private organisations of more efficient technologies (or appliances) to heat/cook, cool, and light up the house/building (i.e. replacement of old refrigerators and air-conditioners with energy-efficient models) |

High, Medium and Low Confidence refersto confidence in conclusions about effects. It indicates the overall rating given to a systematic review based on a careful appraisal of the methods applied in a systematic review, using a standardised checklist.
