NGS COMPARE: PRODUCTS
About & CAWS Index:
COMPARE Product Group Comparison Assessment Sustainability Screening & conclusions
- COMPARE establishes the Key Performance Indicators KPIs, Environmental Performance Indicators EPIs and Social Performance Indicators SPIs for each product group.
- COMPARE places Energy & CO2 as the EPI and noise as the SPI e.g. for electric hand driers.
- KPI Cost of use should equate to the energy per use, e.g. hand driers.
- COMPARE collects data on as many products as we can find easily; applies any calculations necessary to determine comparable data.
- COMPARE then sorts the results in each EPI, KPI and SPI to determine average or normal performance and determines which are above and below the average performance.
- COMPARE then compares individual products to determine where and how they are better or worse than the average or normal.
- COMPARE encourage manufacturers to bring their latest product data to improve the collected data.
NGS COMPARE Group Comparisons
COMPARE took manufacturer or reviewer declared data:
- declared power in watts or kilowatts
- declared duration in seconds
- EPI determined power use
- EPI declared power per number of uses or period of time
- KPI if product is eligible for the ECA Enhanced Capital Allowance scheme
- KPI if product is on the ETL Energy Technology List
- Determine if those not on the list are ‘Or equivalent’
- EPI declared CO2 outputs use
- EPI declared CO2 outputs per number of uses or period of time
- SPI manufacturer declared noise levels dBA at 1 m
- SPI if product is on the Noise Abasement Society Quiet Mark list
- Determine if those not on the list are ‘Or equivalent’.
Average or Normal Performance:
- EPI Calculated power per use in kWh
- EPI Declared power per use of duration in kWh
- EPI Declared CO2 outputs per use: in kgCO2/kWh
- EPI CO2 per 1000 uses or duration in kgCO2/kWh
- SPI Declared noise pressure levels: in dBA at 1 m
- In the absence of comparable data manufacturers can be optimistic in their marketing and sales talk.
- There is some considerable greenwash going on about some below average products.
- In the absence of knowledge specifiers can be fooled by the greenwash.
- Facilities Management catalogues describe readily available low cost kit, but manufacturers improving their kit may not see seen on these lists.
- Some manufacturers develop a model and sell it, other manufacturers create a model and continually develop and refine it; one is on their 8thgeneration of refinements; they are way ahead of the competition.
- If you product is standing still, its effectively going backwards.
- Enhanced Capital Allowance ECA threshold set too high: few are worse and fall below this threshold.
- There is no Market Transformation Programme (MTP) going on in some product groups
- few models are better than average in all these KPI, EPI & SPI.
- COMPARE encourage manufacturers to bring new or better products to drive down energy and CO2 demands and improve efficiency to reduce noise.
- When one manufacturer produces many products or many variants of one product, whose performance varies enormously from variant to variant, it is essential that the exact model name, reference prefix and reference suffix is in the contract specification.
- NBS would argue that is enough, NGS argue that the performance characteristics, the reasons for choosing the product and the model, are also included, so there is a basis for checking deliveries on site and a basis for comparison in the event of substitution; all of this on site or at the point of substitution without reference to other documents.
"Unless workmanship and performance
are defined as part
of the Contract Documents
then any control over the end result
becomes entirely speculative."
