The objective of this work is to evaluate how different building parameters can impact on the building’s energy efficiency, while testing a Surrogate Model implementation for office buildings in Singapore. We train and validate a surrogate model derived from a physics-based building energy model, the City Energy Analyst, aiming to expand the analytic capabilities which are often limited due to model’s computational expenses. Our method ...

Water-related problems affect several billion people’s lives and represent an annual challenge assessed at multitrillion US dollars (WEF 2019), which substantiates their core role in the UN Sustainable Development Goals (UN 2020). Preventing direct and indirect impacts associated with water excess or water scarcity events requires expert judgement based on reliable information. Observations and measurements are fundamental prerequisites ...

The current state of preservation of cantilever retaining walls has attracted considerable attention in the last decade in Switzerland, as destructive tests have detected strongly lo-calised corrosion of the main reinforcement in many walls built in the 1970s. This has been identified as a potential threat that could lead to an unpredictable brittle collapse of the wall, which may cause severe damage to high-traffic roads and even victims. ...
