an-imo is a building physics consultancy company assisting designers and contractors in realising energy efficient, sustainable and healthy buildings.

Annalisa Simonella (Director)

Annalisa has been working in the building envelope physics field for over 20 years, providing design support in hundreds of prominent projects.

She studied Building Engineering at the University of Padova and received her Master of Science in 2001. She has worked for the engineering consulting company Arup in London where she lead the Building Envelope Physics team within the Facade Engineering Consulting Group. Prior to Arup she worked for the R&D department of the facade contractor company Permasteelisa in Italy. In the past 5 years she has been working as a co-director in the design engineering company Loud1 Design. She founded an-imo in 2018 to provide building envelope physics services in addition to sustainable and healthy buildings design consultancy.

Annalisa is a LEED Green Associate, and a WELL Accredited Professional.

Annalisa has developed and delivered professional training course on building envelope physics and energy efficient façades for CIBSE, architects and contractors. She has been an occasional lecturer at the Mackintosh School of Architecture (Glasgow School of Art) and other institutions.
