With all the environmental problems caused by CO2 emissions, energy saving is a hot topic at the moment. Buildings represent a sizeable amount of enery consumption and also a great potential for energy savings still to harvest.

But how much do energy savings cost? How long does it take until you recover your investment? Where can you save energy? And how much CO2 emissions are actually avoided?

This document provides answers to questions such as these, based on commonly used methods of saving energy. Various possibilities for saving energy are discussed in detail.

The five case studies presented in this document are:

  1. Frequency regulator and oxygen sensor for superheated boilers
  2. Energy management system
  3. Thermal bridges
  4. Ventilation
  5. Lighting

How about the *really* simple energy-saving measures?

By Martin Bromley (Energy Efficiency Software) / Published on Tue, 2008-01-29 2:25 Some of the measures highlighted in the report clearly offer a favourable payback. But I wonder if it would have been possible to find some simpler energy-saving measures that would have offered even better payback. Things like:
  • Changing the power-saving settings on office computers.
  • Fitting occupancy sensors to corridor lighting.
  • Basic energy monitoring to discover and target simple sources of energy wastage like office equipment being left on overnight.
