Briones Llorente, Raúl Muñoz Rujas, Natalia Martín, Alexander Millán García, José Antonio Rodríguez Sáiz, Ángel Aguilar Romero, Fernando Rubio Pérez, Gabriel Cost-effectiveness Energy efficiency Energy simulation R&D Recycled materials Urban district Architecture, Engineering and Construction are currently undergoing an energy-digital transition towards a decarbonised and sustainable scene. Energy assessment of buildings through Building Energy Modelling tools allows for in-depth analyses for energy optimization and establishing quantitative proposals for building improvement. This paper shows a comparative study of three programs used for energy simulation of buildings: TRNSYS, HULC and SG SAVE. They have been applied to four Research and Development (R&D) Projects: the energy assessment of a hospital, the energy behaviour of two partially recycled construction materials, and the cost-effectiveness study of energy efficiency measures and renewable energy at the district level, to validate their handling, precision, and result reliability. The comparative assessment shows SG SAVE is the best-valued software: it is free and easy to use, complies with the Spanish energy regulations more easily than HULC, and along with Open Studio makes complex calculations similar to TRNSYS. 2026-02-18 2026-02-18 2023-07 info:eu-repo/semantics/bookPart 978-981-99-2713-5 978-981-99-2714-2 https://hdl.handle.net/10259/11401 10.1007/978-981-99-2714-2_27 eng Building Engineering Facing the Challenges of the 21st Century, p. 485–507 https://doi.org/10.1007/978-981-99-2714-2_27 info:eu-repo/semantics/openAccess Springer
