This document discusses strategies for making existing hotels more sustainable through refurbishment. It outlines key considerations for sustainable hotel design like location, building envelopes, materials selection and more efficient mechanical and electrical systems. A step-by-step approach is proposed that involves assessing the building baseline, reviewing operations, establishing goals, selecting initiatives and implementing upgrades. Examples of typical upgrades that can reduce carbon emissions are also provided such as improving the building envelope, switching to renewable energy sources, and better waste management.

1. Adding Value to Existing Hotels Through Sustainability Gregoir Chikaher, Director of Global Hotels & Leisure

2. Sustainable Hotel- Key Considerations A building’s location affects commuting options, local ecosystems, building energy efficiency and much more. A properly designed and retrofitted envelope helps to maintain the desired indoor conditions and may permit the use of natural ventilation, passive heating, and daylighting. Materials selected for sustainable buildings should have appropriate performance, durability and environmental properties. Material selection can affect issues ranging from our planet’s resources to occupant comfort and health. Economic and Environmental indicators favour the lowest possible man-made changes to the natural hydrological-cycle. The functionality and energy consumption of a space is highly dependent on the lighting and daylighting design. A passive system uses the building characteristics to mitigate negative effects of the external environment or to enhance the internal environment. Efficient mechanical and electrical systems will add value, reduce energy consumption and operational costs and provide better comfort to guests. The resource use of a building is affected by the way in which it is used, operated and maintained Renewables including solar, ground source heat pumps, PV cells and wind power are necessary to reduce Carbon emissions and for a better planet.

3. Sustainable hotel – step by step approach Assess the condition and performance of the building Monitor and control the new performance to obtain the greatest advantage from the capex Benchmark them against industry best practice Step by Step approach Implement the work, which may include staff training and measures to alter the behaviour of guests around water, energy and waste. Identify interventions which are aligned with the goals of the business Package the preferred interventions to suit commercial funding arrangements & Operations Evaluate those in terms of capex, opex, carbon emissions and other indicators
