Building Services Engineering l March/April 2020
Sirus and Engie offer EPIC solutions EPIC, the Irish Emigration Museum located in Dublin’s Docklands, was the wonderful and very appropriate setting for the recent Sirus educational seminar, presented in partnership with Engie Refrigeration, on recovering and recycling heat from buildings. Sirus Group is one of Ireland’s leading building services solutions providers with offices in Cork and Dublin. Its team of 100 people represents BMS, QBMS, mechanical, refrigeration, controls, electrical and thermodynamic skillsets, and delivers services throughout all of Ireland and across Europe. On arrival at EPIC invited guests were greeted by Martin Keogh, Business Development Manager and Niamh Lynam, Marketing Manager, Sirus. They then entered the museum where breakfast was served in one of the many vaults. Shortly after Felipe Ruiz (pictured),

International Sales Manager, Engie Refrigeration, gave the main address. In his presentation he noted that every building could be a ”heat source”, either as a collateral effect of the building activity (occupants, heat rejection from devices, fresh air exchange), or as a primary effect of the building thermal systems (refrigeration circuits within the building’s HVAC system). “In order to recover or recycle heat from a building,” said Ruiz, “you first need to understand the heat cycles within the building. Recovering heat from a building can be profitable from an economical point of view, and also from a sustainability point of view, by reducing total energy consumption, reducing carbon emissions, gaining CO2 credits and improving return on investment (ROI). Eventually, heat recycling could become compulsory if new regulations are imposed (i.e. compliance with nZEB standards). “Furthermore, recovering or recycling the heat from buildings will support EU 2020 targets which are: 20% greenhouse gas emissions reduction; 20% increase in
renewable energy sources use; and 20% increase in energy efficiency. “The heat pump is a clear and present solution to support heat recovery from buildings. The European Heat Pump Association (EHPA) defined three pillars for the heat pump contribution as – Sustainability: mostly on reducing CO2 emissions and total energy consumption; Security of energy supply: diversifying the energy sources while stabilising the supply grid; and finally Competitiveness: improving energy efficiency, thus making the energy more affordable. “Efficient cooling can also be a direct contributor to reducing total energy consumption and sustainable building operation,” concluded Ruiz. The session finished with some Q&A and another presentation before being wrapped up.
