• Buildings potential for climate change mitigation is high. • Mitigation actions in the buildings sector can have significant social and economic values. • These enable the achievement of 4 SDGs, reinforce 7 other. • And are linked to the achievement of 5 SDGs (SDG3, SDG7, SDG8, SDG11, and SDG13). • Trade-offs were identified for 9 SDGs. Buildings are responsible for a big part of total GHG emissions; therefore, their climate change mitigation potential is high. But research shows that mitigation actions in the sector can have significant social and economic values beyond reduction of energy consumption and the associated GHG emissions. This paper summarizes these multiple impacts of mitigation actions in buildings, which are related to microeconomic and macroeconomic effects, health impacts, environmental benefits, better management of natural resources, impacts on social well-being, and energy security implications, and assesses their interactions (synergies and trade-offs) with the UN SDGs. The findings of our analysis show that climate change mitigation actions in buildings enable the achievement of 4 SDGs, reinforce 7 others, and are inextricably linked to the achievement of 5 SDGs, namely SDG3: good health and well-being, SDG7: affordable and clean energy, SDG8: decent work and economic growth, SDG11: sustainable cities and communities, and SDG13: climate action. On the other hand, trade-offs were identified for 9 SDGs, with rather minor implications, which can be further eliminated with the implementation of appropriate policies. [ABSTRACT FROM AUTHOR]

In this paper the application of the travel cost method for estimating consumer surpluses and total values attributed to the Poseidon temple in Sounio, Greece, is presented. The monument in question is one of the most important archaeological sites in Greece, built in the middle of the 5th century BC. The implementation of the method was supported by a survey of the visitors of the monument, through the completion of an appropriately designed questionnaire with personal interviews. The results of the analysis show that the consumer surplus for visiting the Poseidon temple ranges from € 1.5–24.5 million per year, giving useful insights for the amount of money that are socially acceptable to be spent by the Greek state for the protection and maintenance of the monument. Treatment of travel costs associated with multipurpose trips as well as the type of functional form used to estimate how travel costs influence visitation rates, seem to be the two most important parameters affecting the final results.
