5.2 Product valuelifetime extension
The material in this checklist refers to section 2.1.3.2.1 Has the product design been assessed for the following?
• Prolong the product’s useful lifetime – balancing between a legacy product and a newer more eco-
efficient product. •
Ensure durability of product and components:
minimal maintenance and minimizing failure modes;
easy repair and upgrading;
facilitate testing of components;
promote repetitive disassemblyreassembly. •
Balance between technical and economical lifetime:
ensure better cooling;
selection of more reliable components versus other trade-offs such as more expensive materials;
need to build in redundancy. •
Balance between energy use versus lifetime. •
Extend the product’s functional life by:
modularity – allow for ease of repair and upgrading;
standardization of mechanical parts;
software updates;
reuse of mechanical parts. •
Information is made available to end users if appropriate on available options for upgrading, expanding and repair of product.
5.3 Energy efficiency
The material in this checklist refers to section 2.1.3.2.2. Has the product design been evaluated for the following?
• Product meets applicable regulatory requirements, voluntary measures within the industry e.g. codes
of conduct and international standards.
• Product has been assessed for general energy efficiency measures:
Designer is aware of the product’s life cycle “use stage” and the intended patterns of use and system
interactions.
Energy savings features are documented during the design process. Information on energy
useenergy saving modes is made available to the end user.
Enable the most energy efficient “on-modes” and transitions to energy saving modes as the default
mode.
Balance the flexibility of software running on multipurpose devices and the energy efficiency of
special purpose hardware. Consider power saving modes and peak energy shaving opportunities.
Consider product or system related power savings measures:
– system architecturefeature specification;
– power dissipation of battery charging systems;
– identify power-hungry components and features;
– power added incrementally per the system capacity – do not over-specify;
– high efficiencyrenewable power sources;

– means of monitoring power consumption by the end user.
Consider power modes and related energy efficiency measures:
– establish realistic specifications;
– high energy efficiency features when selecting OEM devices.
Consider operational modes – on maximum; on-normal; low power; on-idle.
Consider automatic low power, on-idle modes, power-off modes soft-off; hard-off, and no-load
modes.
Consider operational environment improvements:
– cooling methodology;
– effect of operating environment specification to usersinstallers.
5.4 Substances and materials
The material in this checklist refers to section 2.1.3.2.3. Has the product design assessed the following substances and materials issues?
• Hazardousrestricted
substances:
Product meets applicable regulatory requirements and international standards.
Product meets other materials of concern issues e.g. issues driven by end-users, stakeholders and other interests.
• Materials
efficiency:
When specifying materials has consideration been given to: –
reduced variety of materials used; –
reduced amount and weight of materials; –
use materials with lower adverse environmental impact; –
use materials that can be easily recycled; –
avoid materials that have end-of-life concerns e.g. PVC being improperly incinerated and releasing dioxins.
Products should use consumables that can be optimized relative to the product’s functionality.
Select materials for NIE transmission infrastructure that avoid chromated copper arsenate and
creosote oils; have lower eco-impacting metals and finishes; and have materials with high recycled content; cables and wires avoid use of PVC plastic.
5.5 Emissions
The material in this checklist refers to section 2.1.3.2.4. Has the product’s potential emissions been evaluated in the design process for the following?
• Product meets applicable regulatory requirements and international standards regarding emissions to
the environment. •
Chemical emissions – reduce chemical emissions with adverse environmental impact. •
Noise emissions – reduce noise emissions which typically improve energy efficiency.
5.6 Batteries
The material in this checklist refers to sections 2.1.3.2.5 and 3.1.3.2.
