In Nigeria, there is an estimated deficit of 17 million housing units. Power supply is insufficient, and the electricity supply for about 60 million Nigerians relies on private generators, causing noise, pollution, and high expenditures for mainly imported fuel. Altogether, current challenges clearly demonstrate the need for effective energy efficiency policies targeting also the building sector. The Nigerian Energy Support Program began in 2013, among others, with the objective being to support the Nigerian Government in developing the Nigerian Building Energy Efficiency Code. This paper presents two preparatory activities carried out in order to come up with suggestions for a legal framework well suited for the situation on the ground: the Case Study Building Analysis carried out in collaboration with a Nigerian developer and the Nigerian Building Energy Efficiency Guideline, elaborated together with stakeholders. The results of preparatory activities pointed out that the code must put emphasis on climate adaptive design and must define requirements and procedures in a clear and simple way to allow for effective enforcement. Only then can energy-efficient mass housing be feasible in Nigeria. The paper concludes with a description of the Nigerian Building Energy Efficiency Code (BEEC), officially approved and launched by the Federal Minister of Power, Works and Housing on 29 August 2017.

The European building stock is mature, and expanding cities need inclusive and innovative renovation solutions for all citizens while intensifying city densification. The European project EU-GUGLE aims to reduce primary energy consumption by 40–80 % and increase renewable energy use by 25 % through nearly zero-energy building renovation models for initiating large-scale, Europe-wide replication in cities and communities. About 200,000 m2 of residential and public buildings are being refurbished by implementing a balanced mix of technical, socio-economic, and financial solutions adapted to local needs. Six EU partner cities are participating, each revitalizing an urban district: Aachen, Bratislava, Milan, Sestao, Tampere, and Vienna. The comprehensive integrated approach used in EU-GUGLE is in line with the European Smart City initiative, and each participating city has created nearly zero-energy Smart City master plans based upon lowest-energy thermal renovations coupled with innovative renewable energy services incorporating every aspect of smart district life. All stages of the planning, construction, and post-occupancy phases of the large-scale district renewals are being documented, monitored, and evaluated to create sustainable district renovation methodologies for "smart renovations for smart cities" to meet the objectives of the European Commission's Smart Cities and Communities Initiative for reducing greenhouse gas emissions by 40 % within the European Union by 2020. The paper outlines the approach each city has taken and highlights case studies of the individual solutions created in three of the six cities. ; This is a pre-print of the following work: Bisello, A., Vettorato, D., Stephens, R., Elisei, P.
