The Armstrong Design Envelope Circulator has received a Diamond-level product Sustainability Award for its impact on reducing energy consumption and associated carbon emissions in buildings. This award acknowledges the product’s contribution to more sustainable building operations.
The Problem with Traditional Pumps
Conventional heating and cooling systems often use constant-speed pumps, which operate at full capacity regardless of the actual heating or cooling load. The continuous operation at maximum output leads to unnecessary energy expenditure, particularly during periods of low demand
The Intelligent Solution: Variable Speed Technology
The Armstrong Design Envelope Circulator uses variable speed technology to dynamically adjust output to match real-time building requirements. Instead of operating at a fixed speed the new design envelope circulator modulates output based on current conditions, minimising energy use by only delivering the necessary fluid flow.
Energy Savings: A Win for Buildings and the Environment
Independent studies have shown that the Design Envelope Circulator can achieve substantial energy savings compared to traditional constant-speed pumps – saving an enormous 82% on energy costs per year. By optimising pump performance, the Circulator reduces the electricity required for fluid circulation within the building’s HVAC system. These reductions translate to lower operating costs for building owners and a decreased overall energy footprint.
Sustainable Design and Packaging
The product is designed to be quickly and easily repaired. The Design Envelope Circulator is also significantly lighter than other similar products, weighing only 4kg. This, along with bulk packaging and 97% recyclable components, reduces the waste and transport footprint of the product.
Diamond-Level Award Recognition
The Diamond-level Product Sustainability Award recognises the Design Envelope Circulator’s exceptional environmental impact, and its contribution to advancing sustainable building technologies. It shows how innovative engineering can create effective and environmentally responsible solutions for HVAC systems.
Industry Impact and Future Directions
This award recognises the exciting potential of sustainable technology solutions to drive positive change and improve business outcomes across the building, real estate, and hospitality sectors. The impressive results of the Armstrong Design Envelope Circulator serves as an example to encourage further innovation and wider adoption of leading efficiency-focused technologies.
