E-efficiency is NHER's online energy assessment, calculation and advice system. It is has been used by major energy providers such as npower, Scottish and Southern, Marks & Spencer and the Energy Saving Trust (EST).

E-efficiency is designed for use by:

  • Members of the public e.g. householders
  • Corporates concerned with energy efficiency e.g. energy companies

The system is available in two forms: the full solution and the calculation engine only.

The full solution:

The full E-efficiency solution was developed for UK energy companies. The system comprises three distinct elements.

  • An online energy efficiency survey for use by members of the public. This displays immediate results and recommendations to the user
  • A searchable online energy efficiency advice centre specifically aimed at householders
  • An administration interface that allows configuration of the application, including the linkage of product offers to the recommendations provided by the system and access to the underlying database

The calculation engine:

Our calculation engine is also available to licence as a discrete applicatio and can be hosted by NHER on secure servers, or your own.

  • Uses the NHER DIYSAP set of data input items
  • Generates an energy rating, running costs, and a set of improvement recommendations

The calculation engine was licensed to the Energy Saving Trust, the government agency responsible for encouraging energy efficiency in the UK's 25 million homes.
