Sustainable Maritime Interiors - 2022 Report

82 Procurement practices come in for enhanced scrutiny when planning for sustainable interiors. Factors to consider include use of salvaged or recycled materials; choosing materials with carbon sequestering properties; specifying that manufacture incorporates the use of renewable energy; sourcing locally; and using low-emission transportation to move materials.1 Maritime interiors are also taking influences from ideas about green building best practices in the hotel construction sector, spanning a range of best practices, from avoiding environmentally harmful materials to using energy-efficient technology in construction. The 2019 IFC report ‘Green Buildings: A Finance and Policy Blueprint for Emerging Markets’ defines a green building as satisfying all three of the following criteria: certified as green under one of the internationally recognised certification standards or an approved national standard; at least 20 per cent more resource efficient than a baseline building without resource-efficient design; and able to quantitatively report impact metrics, such as energy, water and materials savings, and GHG emissions reductions.2 The Global Sustainable Tourism Council for hotels sets three green design criteria: use of local materials, practices and crafts where practicable and appropriate; sustainable design, materials and construction practices, with appropriate certification where possible; and environmentally sound sorting and disposal of waste from construction.3 Building certification schemes Certification schemes such as BREEAM and the US Green Building Council’s LEED system encourage sustainable choices to be made in the early stages of design. Although they were conceived for land-based construction needs, ship owners are increasingly exploring if it is possible to certify through them. LEED Promoted as “the world’s leading green building project and performance management system,” LEED (and in particular, the latest set of strategies established by LEED 4.1) seeks to deliver a comprehensive framework for green building design, construction, operations and performance, focusing on material selection, human comfort, air quality and human health features of a building as well as social equity. LEED 4.1 certification prioritises the use of sustainable materials by manufacturers, lowering a building’s environmental impact and helping reduce “energy, water, waste during manufacturing, carbon footprint during distribution and transportation and overall carbon emissions through the entire production life cycle”.4 1 Source: Carbon Smart Materials Palette, Whole Building 2 Source: International Finance Corporation, Green Buildings 3 Source: Global Sustainable Tourism Council, G5TC 4 Source: US Green Building Council, LEED 4.1 INTERNAT IONAL WI SDOM
