Towards Nearly Zero Energy

Annarita Ferrante, Ph.D, post-doctorate researcher at national and European level, School of Engineering of the University of Bologna, is now Associate Professor in the same Department. She is the author of 3 monographs and author/co-author of 100 national and international papers on issues related to the sustainability, with special reference to the energy and environmental rehabilitation in existing contexts. She is a reviewer in scientific journals like Applied Energy, Energy and Buildings, Building and Environment, Advanced Energy Research.She was and is actively involved in the participation of national and European research program (PRIN 2007-2009), municipality of Bologna, CEPA_WIND Agreements, Minister of Environment, etc.

1. (INTRODUCTION) 1.a) Urban Environments and energy related issues 1.b) Heat Island in the mediterranean cities. The case study of the Athens Metropolitan Area (AMA) 1.c) Policy background and zero energy case studies at urban and building scales 2. nearly Zero Energy Urban Settings (ZEUS) 2. a) Urban discretized model: homogenous urban areas and urban units of the city 2. b) Case studies’ selection and potential reiterative units at the district city scale 2. c) Three representative Urban environments in the AMA 2. c1) The Energy Demand in the selected urban environments 2. c2) The Energy Saving potential of retrofitting options at the building’s scale 2. c3) The Energy generation and balance by renewable energy sources at the building’s scale 2.c4) The energy saving potential of green and passive techniques in the selected urban environments 2. d) On the technical feasibility of nearly ZEUS 3) OVERCOMING EXISTING CONSTRAINTS TOWARD ZEUS 3. a) Is the technical feasibility associated to the economic feasibility in the ZEUS? Important Economical barriers for ZEUS 3. b) Why do we believe in the economic feasibility of nzebs in existing urban environments? Energy and Non- Energy related issues in the energy retrofitting as Possible incentives towards ZEUS 3. c) To what extent is deep renovation towards nZEBs competitive with respect to shallow or standard retrofit? Cost-benefit analysis of deep renovation and volumetric additions in energy retrofitting actions towards ZEUS 3. d) Expandable Architecture, Add-Ons and Tailored solutions to increase the techno-economical Feasibility of ZEUS 3. e) Legislative barriers and designed solutions 4.
