- Resource Efficiency:
As for its existing hotels, Amata is planning to integrate several water and energy conservation measures in the design of the project, such as:
- Better use of natural light and ventilation (high Window to Wall ratio, vertical and horizontal exterior shading on windows with a high shading factor, Naturally ventilated non air-conditioned corridors);
- Energy and water efficient fixtures and fitting (Individual air conditioner units with inverter technology; high efficiency LED lights, occupancy sensor control of lights in corridors, low-flow showerheads; aerators for taps; dual flush for all water closets; installation of solar hot-water collectors)
- Selection of energy efficient equipment in kitchen and laundry.
In addition, UIG is exploring the possibility for the project to achieve IFC’s EDGE certification (
http://www.ifc.org/EDGE) for green building design.
- Energy Supply and GHG Emissions:
For all the operational properties, as well as those proposed under the project, electricity, sourced from the national grid, is/will be used for lighting, air conditioning, elevators, water heating and other mechanical and electrical systems in the back of the house. As a backup for emergency use, diesel generator sets are provided. In all its hotels, air-conditioners and electrical heaters for generating hot water are installed as individual units in each room and there are no centralized chillers or boilers. As such, there will be minimal air emissions from the project.
GHG emissions from the project are primarily due to energy consumption (electricity and gas) and any leakage from refrigeration systems. Accordingly, it is estimated that the project will result in GHG emissions of *** tons of CO2eq/year, once it is fully operational. Actual records will be used to review GHG emissions from the project once it becomes operational.
- Water Supply and Wastewater Management:
UIG sources water for its hotels from deep wells in its premises, and treats this water to potable levels. Treated water is regularly tested to ensure its conformance with WHO drinking water quality standards.
Currently, sewage treatment for its existing hotels is by septic tanks across its facilities. However, for the expansion project, UIG is exploring zero discharge packaged wastewater treatment systems provided by Japanese suppliers, where the treated wastewater shall be used for gardening.
Thus, in Amata Inle Lake there will be two ways of managing sewage waste: First, a conventional septic system for the existing hotel building, where a settling and decomposition chamber will allow sewage solids to separate from liquid and undergo partial decomposition. Decomposed solid waste will be stored as sludge at the bottom of the tank; while the effluent from the tank will flow by gravity into a subsurface absorption field where it will infiltrate into the soil. When septic tanks are full, these will be emptied by the Nyaungsh
we township municipality.
For the proposed expansion project, a packaged 3-Chamber bio-tank system will be used. The first chamber will allow for disinfection of sewage using micro-organisms. The second chamber is the sludge sedimentation tank and the last chamber is equipped with an evaporation funnel to store fluids. Treated wastewater from this system shall be used for gardening. A similar system is being explored for the new hotel development in Bagan.
Regular monitoring will be carried out on the septic tank and bio-tank systems to ensure that they are not overloaded.
As described in the IEE report for Amata Inle Lake project, there will be no direct discharge of treated sewage into the lake, and impacts of treated sewage disposal (through land application or reuse for gardening) on the Inle Lake water environment and its ecological carrying capacity are expected to be very limited when compared with the potential impacts of treated sewage disposal and nutrient loading from other neighboring hotels.
- Solid and Hazardous Waste Management:
As in the existing hotels, post-expansion for the hotel will also follow the process of reduction, segregation, recycle, reuse for the solid waste. While recyclable waste (such as glass, paper and cartons) is sold to local recyclers, the other waste is disposed of through the municipal solid waste management systems. Leftover food waste is given away to nearby villagers as animal feed.
