HEATING, VENTILATION AND AIR CONDITIONING WHY IT PAYS TO BE PREPARED In September, mandatory requirements relating to NOx emissions are set to come into force for space heating under the Energy-related Product directive (ErP). Where like-for-like boiler replacements are no longer a possibility, it pays to be prepared, says Chris Meir, sales director at Remeha Heating is a critical service in a building – and particularly so in educational establishments where a reliable heating system is central to achieving a comfortable, productive learning environment. As budgets continue to tighten, ensuring that the heating system operates efficiently also helps avoid unnecessary energy waste, resulting in lower operating costs and a reduced carbon footprint. Legislation like the European Union’s Energyrelated Product directive (ErP) aims to support improved heating efficiency with minimum performance standards for heating technology. In September 2015, ErP introduced tighter energy efficiency requirements for all space heaters including boilers up to and including 400kW. And from this September, ErP turns its attention to air quality, with the enforcement of new mandatory requirements for nitrogen oxides (NOx) emissions from heating. With many school, colleges and universities relying on commercial boiler plant for their heating, where boiler replacements are concerned, it pays to be prepared. 40 BUILDING PRODUCTS | MARCH 2018 More stringent NOx requirements Under the Ecodesign Directive of ErP, maximum NOx emissions of 56mg/kWh will be enforced for gas and liquefied petroleum gas (LPG) boilers and 120mg/kWh for oil-fired boilers. The legislation, which comes into effect from 26 September, applies to new equipment up to and including 400kW on both new build and replacement projects. The implications The new legislation will have implications for building managers and facilities providers. On new build establishments, the focus should be on ensuring that only ErP-compliant high efficiency low NOx heating products are specified and installed. The same is true for refurbishment projects. However, it pays to plan ahead as ErP may well mean that like-for-like boiler replacements are no longer possible. Instead, ErP may require a switch of technology and/or fuel supply to a cleaner, more efficient heating alternative for compliance. Future-proof option The good news is that ErP-compliant boilers are readily available in the shape of condensing boilers. Of all the boiler types, condensing boilers are the most energy efficient. With the latest advanced models capable of achieving near maximum gross efficiencies, they easily comply with all regulatory requirements. At the same time, these high-performing boilers are engineered to meet ultra-low NOx criteria, at or below 40mg/kWh. As such, they meet the EU standard EN15502 Pt 1 2015 Class 6 for NOx and are future-proofed to ErP 2018 NOx requirements. Importantly for educational establishments in off-grid locations, some of these advanced condensing boilers are also certified for operation ErP may mean that like-for-like boiler replacements are no longer possible Clifton College has replaced old cast iron boilers with ultralow NOx boilers to make its heating system more efficient
