What if all new homes had a car-charging point?
All new homes having a car-charging point would be a step in the right direction, says Ashley Osborne, but, in the short term, it could create more problems than it solves.

In recent years, the energy efficiency of building stock has been recognised as a significant route to contributing towards meeting European Union energy targets, by reducing energy demand and associated greenhouse gas emissions.
Furthermore, improvements in energy efficiency across the built stock can provide energy security by lessening the reliance on external suppliers and increases energy affordability, which has numerous social benefits. The overall driver pushing energy efficiency higher up the priority ladder is to achieve the EU’s energy savings targets of 20% by 2020, rising to 32.5% by 2030. To try and achieve this the EU has implemented a variety of policy instruments.
Due to energy efficiency being viewed as an essential mechanism to assist the EU in meeting energy and climate change targets, the need to assess the effectiveness of these policies has arisen. Thus, a database – EU Building Stock Observatory – was created to facilitate the continual evaluation of the impact of energy efficiency policies concerning existing buildings across the EU
The BSO is a European Commission initiative which monitors the energy performance of buildings across Europe’s 28 member states and the EU as a whole. The BSO database holds over 170 energy efficiency indicators for each member state, which cover five broad topics:
These topics were developed to facilitate the assessment of energy efficiency improvements of the built stock and the impact of this on the actual energy consumption of the building sector overall.
The overall driver pushing energy efficiency higher up the priority ladder is to achieve the EU’s energy savings targets of 20% by 2020, rising to 32.5% by 2030.
Through the energy efficiency indicators in the BSO and associated topics, the data presented gives an overarching view of energy consumption patterns within each building typology across the EU. Thus, the primary driver of the BSO is to provide a clear understanding of the effectiveness of EU policy measures and of market support mechanisms, which will steer an improvement in the depth and rate of building renovations to enhance energy efficiency across the EU.
The BSO aims to provide a snapshot of which building typologies across the EU built stock can garner the most significant energy efficiency and energy performance improvements, through enhancements in policy and technologies. The significance of this is that the project will steer future EU energy efficiency policies, support mechanisms, and initiatives to contribute towards meeting energy and climate change targets.
However, at present there is a significant obstacle facing the BSO, the database currently lacks enough robust data to allow conclusions to be drawn. One of the main issues is that a number of indicators within the BSO do not have reliable data that is measured, known, or publicly available (eg. EPC rating by floor area).
A further concern is that approximately 10% of indicators in the database, were filled through various EU funded service contracts (ie. Inspire, Tabula, Entanze) which have now reached completion and are not likely to be repeated, suggesting that they will likely remain as persistent data gaps unless other sources can be identified.
