ENERGY MANAGEMENT
Sponsored by Armstrong Fluid Technology MAKING ENERGY MAKE SENSE
Armstrong Fluid Technology takes a look at the importance of developing solutions that cut installation and operational costs whilst minimising lifecycle carbon footprint.
The carbon footprint of a building is heavily dependent on the environmental performance of its HVAC system after installation. Around 5% of carbon emissions relate to the manufacture of the product, compared to 95% involved in operation throughout its lifetime. Armstrong Fluid Technology’s objective is to lead the HVAC industry in the development of solutions that minimise lifecycle carbon footprint and offer both the lowest installed cost and lowest operational cost.
Historically, HVAC system designs have viewed the system as an assembled collection of independent components, with limited connectivity and little in the way of performance monitoring technology. Armstrong’s approach is to take a holistic view of the HVAC system, adjusting the output of each component to deliver the required heating or cooling, but with minimised consumption of energy.
Armstrong Design Envelope solutions reduce costs and improve environmental performance through variable speed, demand- based operation — consuming only the energy required, based on current system demand. The variable speed intelligence embedded in the controller enables the pump to respond automatically to system load, adjusting the speed of the pump and drawing only the power required to meet that load.
The same optimised performance is provided over a wider operating range than standard variable speed pumps, preventing the risk of underperformance if building usage and system demand change. This ensures a building’s hydronic pumping system consumes as little energy as possible, delivering reductions in consumption of up to 70% (compared to fixed speed models), minimising carbon impact and energy costs. Armstrong Design Envelope pumps also offer valuable installation savings, as they eliminate the need for external sensors and reduce the requirement for extra fittings and installation labour.
Armstrong’s Pump Manager performance management service helps operators ensure that pumps continue to operate efficiently and reliably throughout their complete lifecycles. Pump Manager is a cloud-based application that uses the embedded intelligence and connectivity of Armstrong Design Envelope pumps to provide performance reports to system operators.
With this information, operators can make changes and address issues to optimise HVAC performance. Online trending and

analysis across multiple parameters on single pumps, or on an aggregated basis for multiple pumps, assists in identifying performance degradation and facilitates a predictive and proactive approach. Pump Manager will, for example, report issues such as excessive vibration, a broken coupling, risk of cavitation or a dead head should they occur, or conditions such as impeller imbalance, bearing failure, seal failures and shaft misalignment that would impact on operation of the pump if undetected.
Compatible with industry-standard BMS, EMS or CMMS solutions, Pump Manager helps reduce operating costs by providing data to support continuous optimisation of pump performance. Pump Manager also increases pump availability and reliability, reducing unexpected failures and providing early problem detection. Lastly, Pump Manager helps organisations report their energy use and environmental performance. This is particularly important for those organisations required to provide Streamlined Energy and Carbon Reporting (SECR).
Armstrong solutions are delivering tangible energy savings across the world. To provide even more value for our customers, we are building out our global Emergency Response Network. This will involve global cooperation and coordination with Armstrong Service Partners, employees, customers and consulting engineers, as well as our sales and channel partners.
