Create fossil free energy production for hospitals


Climate engineers Florent Donnard and Jean-Marie Melo discuss why, in order to create opportunities for energy and waste heat recovery in hospitals, the creation of energy profiles for such facilities is so important.


Since the Meadows report The Limits to Growth published in 1972 and the 1992 Rio de Janeiro United Nations Conference on Environment and Development, the world has gradually realised its considerable impact on the environment. As different IPCC reports have been released, the link between carbon emissions and other greenhouse gases, the scarcity of energy resources, and environmental damage has become clear. Alongside these environmental crises, the world has also experienced geopolitical and economic disruption. The combined effect of these events creates an array of constraints, leading public authorities to implement actions for a low carbon footprint and low energy consumption. In France, greenhouse gas (GHG)


emissions per business sector are distributed as shown in Figure 1. Healthcare, included within the


industry and construction and residential and tertiary activities sectors, accounts for eight per cent of French GHG emissions, according to the Shift Project studies. Considering the essential position of the healthcare sector in the French social model, we think that our French and European healthcare facilities should set a positive example in terms of controlling and reducing their carbon footprint. How can a hospital


work towards ‘zero- carbon’? After explaining the creation of energy profiles for these facilities to define their needs, we will present opportunities for energy and waste heat recovery. By highlighting the different carbon footprints of energy sources in France and

we need to understand it in three stages: l Controlling its consumption and


Florent Donnard


After his debut as a professional installer, Florent Donnard, a graduate engineer from ESSTIN (now Polytech Nancy), joined the HVAC engineering department of the AIA group’s Nantes


branch in 2007. While working on a wide range of building types (offices, teaching, technical centre), he has come to specialise in private hospital projects (several clinics for the ELSAN group – Nantes, Narbonne, Angoulême – extensions to the Clinique Jules Verne in Nantes,


several SSRs for the LNA santé group) and public projects (partial restructuring of a high-rise building at the Pontchaillou University Hospital in Rennes, Hôpital Femme Mère Enfant at the CHR in Metz, reconstruction of the Caen University Hospital). In addition to his role as an HVAC specialist, he is now also the AIA Group’s ‘healthcare design’ contact for HVAC design issues.


Jean-Marie Melo


After graduating from ESEM (now Polytech’Orléans) with a degree in fluid mechanics, Jean- Marie Melo began his career in energy management and the building industry by drawing up an Environmental Enterprise Plan for all the fire stations in the Deux-Sèvres département


(79). Following this experience and being convinced that building is a major lever for energy management, Jean-Marie continued his studies to obtain a DU in Renewable Energy and Building at the University of Chambéry. Since 2013, Jean-Marie has been working at AIA’s


Paris office, developing hospital projects such as the Institut Curie in Saint Cloud and the CHU in Caen. Today, he oversees the HVAC and plumbing design department of the Paris agency and is involved in renovating the HVAC technical services of the Centre Pompidou.
