Result description
Energy retrofitting of tertiary buildings through a Business-to-Business (B2B) refurbishment contract offered by a private Energy Services Company (ESCo). The aim of the contract is to implement active and passive solutions to lower the energy demand of the buildings and guarantee that the targets are achieved through Measurement and Verification (M&V) plans.
The Spanish energy company Naturgy implemented retrofitting actions to lower the energy consumption of over 10,500 m2 of tertiary floor in Barcelona. Three buildings with very different uses were retrofitted: a hotel, an educative centre and a sports centre with a swimming pool included in its premises. A wide range of measures were deployed, such as façade and roof insulation, replacement of windows, insulation of the pool and installation of dehumidifier in the sports centre, boiler replacement, new LED-lighting, a Smart Building Energy Management System, aerothermal heat pumps and adding photovoltaics to the building façades.
Lessons learnt
In order to guarantee potential energy savings of retrofitting projects, it is recommended that minimum quality levels and performance penalties are included within the ESCo contract. The indicators to assess energy performance should be reviewed by the ESCo and facility managers in order to understand all the variables behind the M&V plan.The installation of a Buildings Energy Management System can help the building operator to optimize the energy consumption and also make users aware of the positive approach they are taking towards consumption and production (where photovoltaics were used).
Upscaling & replication potential
One aspect that impacts on tertiary refurbishment is the landlord-tenant split incentive issue (a circumstance in which the flow of investments and benefits are not properly rationed among the two parties). The company operating the facility may not invest on energy efficiency measures due to a too short concession period to recover the upfront costs. Solutions could be public concessions that consider energy efficiency investments or green leases versus a regular lease by the Private sector.
