Environmental protection technologies in hotel energy systems: prioritising energy efficiency in post-war recovery

Abstract

This article develops an integrated conceptual framework for post-war hotel energy reconstruction grounded in the synergistic application of the Build Back Better principle and the Energy Efficiency First doctrine. In conditions of large-scale infrastructure destruction, hotels represent energy-intensive assets whose rebuilding creates a critical opportunity to prevent carbon lock-in and accelerate low-carbon transition pathways. The study applies structured conceptual and thematic synthesis of international scientific literature and policy documents to systematise technological, architectural, digital and governance dimensions of resilient energy architecture. The paper argues that reconstruction must prioritise intrinsic energy demand reduction through high-performance envelopes, passive design strategies and efficient HVAC systems before expanding supply capacity. Renewable integration, electrification and decentralised generation should follow minimised demand profiles. The proposed model demonstrates that aligning EE1st sequencing with resilience objectives generates reduced lifecycle consumption, enhanced energy security, lower emissions and improved operational continuity in post-war recovery contexts.
