When To Use Energy Labels or MEPS (Minimum Energy Performance Standards)

Energy Labels
It is important to remember that labeling and MEPS programs aim to influence the selection of products by consumers at the point of sale by making higher efficiency units more attractive (through labeling) or by making less efficient ones unavailable (through MEPS). Labeling or MEPS cannot be expected to have any significant ongoing influence on consumers’ use of products once they have been purchased and installed. (more…)

Energy Endorsement Labels: Dial Label, Bar Label, Linear Label

Energy Labels
Endorsement labels indicate that the products carrying the labels belong to the ‘‘most energy-efficient’’ class of products or meet a predetermined standard or eligibility criteria. These labels generally consist of a logo or mark that indicates the products have met the standard and generally contains little or no comparative energy efficiency information (although this may be available through lists of endorsed products). These labels merely inform consumers that the products meet the required standard. Criteria for some schemes are updated on a regular basis; therefore, these labels may carry the year of qualification. Endorsement labeling programs are mostly of a voluntary nature. (more…)

Energy Efficiency Improvements and Variations

Energy performance ratings tell what the energy performance of a building is, but if the energy performance of a building is to be improved, the causes of lower than desired performance must be understood, and methods of achieving improved performance must be determined. Causes of variation in energy performance among commercial buildings are understood to a degree, but much remains to be learned. (more…)

Measuring Energy Performance for Residential and Commercial Buildings

Interest in rating the real-life energy performance of buildings has increased in recent years, and the real life efficiency performance rating of buildings is important for any sustainable energy future. (more…)

Usefulness Of Fuel Cycle Analysis Results based on ISO 14040

ISO document 14040 identifies four areas for using life cycle analysis (LCA) results:

(1) identifying opportunities to improve the environmental aspects of products,
(2) helping industry, governments, and nongovernmental organizations make sound environmental decisions,
(3) selecting relevant environmental indicators for measuring the environmental performance of products, and (more…)

Compulsory and Voluntary Energy Efficiency Programs

There are only a few compulsory energy efficiency programs aimed at industrial facilities. It is only recently that the EU introduced a Directive aimed at the energy performance of buildings that makes it mandatory to carry out energy audits of large commercial buildings at regular intervals.
