News from LPCB and BRE Certification

New roofing system approval
LPCB has approved Liquid Plastics Limited’s Decothane Gamma 20 and
Decothane Delta 25 Roofing Systems to BS 476:Part 3 and ENV 1187: Test 1,
Test 2 and Test 3. This is the first liquid roofing membrane to be approved by
LPCB. The product is applied cold and therefore there is not the fire risk
associated with flame applied roofing products.
By using LPCB approved roofing products, roofing contractors are
demonstrating their commitment to reducing the number of hot work
fires and this will hopefully drive down their liability insurance premiums.


Transportable pressure equipment directive
BRE Certification (incorporating LPCB) is now a Notified Body under the
Transportable Pressure Equipment Directive. Following a successful
assessment, the manufacturer may apply the ‘Pi’ Mark shown here. This Mark
symbolises the conformance of individual elements or assemblies with the
requirements of the directive. Such marking does not provide an indication
of performance, but rather that the equipment is safe to transport
pressurised fluids.

Waste
The operation of retail businesses can involve particularly large
amounts of waste because of the quantities of packaging that
must be dealt with on a daily basis. The BREEAM Issue Category
for ‘Materials’ has been adapted for retail (and renamed ‘Waste
and Resources’) to reflect this.

stage. As part of the package the user will be trained to apply the
methodology to their retail development, and to gain an accurate
benchmark of their performance which is comparable to the
BREEAM standard. This allows retailers to start a process of
assessment and improvement using the BREEAM Retail
assessment methodology without actually having to commit to
a formal independent audit. The BREEAM Retail self-assessment
package will be available from November 2003.

Summary
The Directive provides a significant and realistic opportunity to
substantially reduce energy use in buildings. Major issues remain
to be resolved – including those associated with building labelling,
certification and plant inspection – with important implications in
terms of research, development, demonstration and training.
Early engagement by industry, professional institutions and trade
associations with the relevant government departments is vital to
ensure that the Directive is successfully transposed into law within
the three-year deadline set by the European Parliament and
Council. At a time of increasing corporate social responsibility the
Directive could deliver significant benefits for energy managers by
ensuring that major organisations invest in cost-effective energy
efficiency measures.
