environment, because buildings are a leading contributor of GHG, with the building’s HVAC system making up a significant portion of the energy use.”


Clearly, the HVAC and building management systems manufacturer is a business which understands the extent of its influence and takes its green credentials very seriously, consciously designing and providing solutions which enable its customers to prioritise sustainability. Jose La Loggia, vice president and general manager for Trane Europe, explains that Trane offers its customers a multi-pipe HVAC system for high efficiency, simultaneous heating and cooling.


Stressing the complexity of modern, multi-function buildings, he says: “Simultaneous heating and cooling capability is increasingly important for operating and providing comfort within the building, but there is also a great need to reduce carbon footprint and save energy.


“The best way to save energy is to not use it. However, if you must use it, the second best way to save energy is to recover and repurpose it. This system repurposes rejected energy, or uses renewable energy, for heating the facility, delivering a more sustainable solution that reduces the amount of investment costs, use of floor space and total operating expenses.


“The multi-pipe system further contributes to lowering the environmental footprint of a building due to significantly lower energy use and minimised refrigerant content.” Meanwhile, Trane’s EcoWise products have been developed to reduce climate impact while offering lifecycle performance. It was in 2014 that the business introduced the Trane Series E CenTraVac, the first available chiller for use with ultra- low global warming potential (GWP) refrigerant, R1233zd. Since then, Trane has continued to expand this pioneering product portfolio, with Europe leading the way. One notable


addition has been the Trane Sintesis eXcellent air-cooled chiller series, with three levels of performance and sustainability options.


Mr La Loggia explains: “This portfolio combines the best efficiencies of the global market, as all 10 best-certified air-cooled chillers are Trane Sintesis eXcellent; the lowest refrigerant content; dual circuits, which offer reliability and refrigerant containment; and the lowest available GWP impact of the used refrigerant. The Sintesis platform also allows further energy savings such as integrated free cooling in four different versions.” Trane in Europe has also redesigned its complete screw compressor chiller offering, which is now available with R1234ze – a near zero GWP refrigerant. “The full optimisation is illustrated by the smallest physical footprint as well as a capacity reach to 1700kW – air- cooled – and 2700kW – water- cooled – which is unique in the industry”, says Mr La Loggia. He adds: “With the technology available today, we balance our choice of refrigerant with safety factors, such as toxicity and flammability; environmental impact, seeking the lowest possible greenhouse gas emission; and energy efficiency, to lead the industry with the first portfolio that uses next generation refrigerants and offers our customers choices.” For Ingersoll Rand to keep its Climate Commitment going forward, the EcoWise range will play an integral role.


Indeed, Mr Simmons explains that the business set an even more demanding target here: “We committed to cut the GHG footprint of our refrigerant-bearing products by 50% by 2020, and to incorporate lower GWP alternatives across our portfolio by 2030. To meet this, we are transitioning to lower GWP refrigerants – without safety, efficiency or other trade-offs – faster than required.”


Across the business as a whole,


CLIMATE ACTION


sustainability has been factored into the product development process, with Ingersoll Rand’s Center for Energy Efficiency and Sustainability (CEES) being partnered with consultancy UL Environment (ULE) to develop the Design for Sustainability (DfS) Certificate Program. In addition, Ingersoll Rand plans to extend the reach of its sustainability-driven agenda through its supplier base.


“We have collaborated with our preferred suppliers to jointly own goals around sustainability and identify solutions – whether it’s sourcing materials from new places or improving packaging”, says Mr Simmons.


Sustainable futures


It is through dedicated research, innovation and collaboration that Ingersoll Rand has met its Climate Commitment – in an approach which it must sustain as environmental issues continue to grow in magnitude and consumer-consciousness increases.


While acknowledging these challenges, Mr Simmons is positive about their influence and the role Ingersoll Rand has to play in contributing to a more sustainable and energy efficient future: “The energy grid is transitioning and the ways we think about energy supply and energy demand are evolving in exciting ways.


“Customers have an increasing number of options related to energy sources – bio-based, reneweable, traditional – which lead to innovations in the marketplace. In addition, energy management solutions provide customers like building owners with new ways to understand efficiency opportunities and to use data and analytics to better manage energy resources. “We are seeing increasing interest in pursuing goals such as zero energy buildings thanks to efficiency innovations, like storage, that can enable a new level of energy use and resource conservation.”
