GROUP SUSTAINABILITY REPORT 2010
FAIRMONT HOTEL, MUSCAT, OMAN
WSP Middle East has provided MEP and structural design services for a new 5-star, 360-key hotel and apartment complex in Muscat, Oman. This project is typical of many of the design commissions WSP is asked to undertake, in that it did not have specifi c sustainability targets, nor was it targeting accreditation to an international rating system such as LEED, BREEAM or Green Star as part of the brief.
WSP assessed the energy demand and associated carbon emission for a “business as usual” case, which was based on design standards typically applied in the region on similar projects. For this scenario, the hotel’s energy consumption was calculated to be 208kWh/m2 per year, which would result in carbon

emissions or equivalent (CO2e) of 12,200 tonnes per year.
SHANGHAI LUX, CHINA
WSP Hong Kong has been providing sustainability design and LEED consultancy services since 2007 for the Shanghai LuxChina mixed-use project. The project is located in the prime location of Changning district in Shanghai. The proposed building comprises a four-storey basement for parking and retail use, four-storey above- grade podium for retail use and 24-storey “A-grade” offi ce tower. The building will become an important local landmark, which houses fl agships for LVMH and other well-known retailers.
As sustainability and LEED consultant, WSP worked closely with the project team to achieve a cost-effective green building design. Synergies between disciplines, and between technologies, kept costs low while raising design standards. Design charrettes were held at different project stages to involve the entire team in the whole design process, allowing them to build relationships and balance the needs of each team member against all project goals.
The building is designed to consume less energy and water than conventional buildings with enhanced indoor air quality for users and workers. In addition, the project is reusing and recycling 75% of construction waste. The building aims to consume 14% less water than a ASHRAE 90.1-2004 code-compliant building and 50% less potable water than conventional buildings. By using an intelligent and high- effi ciency irrigation system, the irrigation water demand can be met by the rainwater harvesting system in the building.
The project aims to achieve a Gold LEED – Core and Shell rating upon completion and was pre-certifi ed as LEED-CS Gold in May 2009.
WSP’s proposed design had an energy consumption of 144kWh/m2. Therefore, our design sought to reduce its carbon
emissions by 30% to 8,450 tonnes CO2e/ year. This would be achieved partly through the inclusion of heat recovery systems and improving the performance of the building fabric and glazing. The balance of the reduction was achieved by connecting the hotel to a district cooling system being provided by others to service the wider development.
WSP also examined the impact of material selection and management within the structural design of the hotel. This included strategies to reuse 14,000m3 of excavated material onsite and also the specifi cation of cement containing a minimum of 66% ground granulated blast slag. This measure reduced the embodied carbon content of
the building by 29,000 tonnes of CO2e. The hotel is scheduled to open in 2013.

The intelligent and highly effi cient irrigation system means that the building’s demand for irrigation water can be met by rainwater harvesting.
