Sabadell executed a domestic energy saving campaign for 29 private dwellings, as voluntary families were granted a Smart-meter (Efergy e2) for a six-months period. The aim of the campaign is to promote co-responsibility of citizens in GEH reduction through awareness raising. Instant information (kWh, kg CO2.eq and euros) provided by the smart-meter allowed the beneficiaries to monitor consumption and implement energy saving practices to promote behavioural change. Housing type under study is a multi-family housing, 76 to 100 m2, with a contracted power/tariff of 4,4 kW and a natural-gas heating system and air conditioning for cooling, with 8,8 kWh of average daily consumption, or GEH emissions of 3.32 kg of CO2. Extremely positive assessment by the beneficiaries were gathered by individual questionnaires and participatory meetings. Savings achieved by families are summed up to 14,3%. Expected CO2 yearly saving for 2020 is 180,6 Tones of CO2 eq as the project will be developed in four phases with an average of 30 dwellings per phase. This campaign has shown extremely positive results in implementing energy saving projects to final domestic energy users. It can replicated everywhere anytime, so it is universal on its application as each family or inhabitant has to improve by themselves its energy profile.

Acronym of the case
This campaign has shown extremely positive results in implementing energy saving projects to final domestic energy users. It can replicated everywhere anytime, so it is universal on its application as each family or inhabitant has to improve by themselves its energy profile.
As main factors of success, it is to be highlighted that the project worked at the household-level, individually, and being in close contact with smart-meter users. Specific, detailed and real data related to appliances’ consumption, daily pattern of consumption, etc were gathered by the users with smart-meter’s help to better take energy-related decisions in the future. This project can really help users to get this information, which is key to move on habits acquisition. Taking into account the energy market liberalization process going on within several EU countries in the last few years, this campaign is specially oriented to guide individual energy users for tariff comprehension and selection.
When replicating this experience, it would be very helpful to get “associated” households or families, that have previous contacts, so the impact on daily-life behaviour shall be multiplied. If possible, a campaign of twelve-month period would better help to see if behavioural practices.

Source of funding
The project will be sustained by own financial sources of the municipality and a limited number of dwellings per year. Project has attracted very positive attention by other local and regional public administration within the Mediterranean area.
The cost is 329,22 euros/dwelling, being 90 euros for the appliance and the rest for staff and overheads.
Financial resources for the project came from two main sources: own sources of the municipality and external funding (32%) from the Catalonian regional government (Environmental and Housing Department of Generalitat de Catalunya).
