Building Envelope

Windows
The window to wall ratio (WWR) is 40% which complies with the Energy Efficient Building Code – Building Envelope Guideline (EEBC) which regulates that WWR must be between 30% and 50% (EEBC 2013).
The number of windows on the south-west facade is limited to avoid effects from the dry, hot Foehn wind. Also, the number of windows on the north-west facade is limited to reduce the solar radiation.
All windows on the top floor where the panoramic restaurant is located are covered by reflective film to reduce the heat gain throughout the floor.

Walls
Shading
Overhangs have been designed for all floor lobbies to help reduce solar radiation on the south-east oriented facade.

Over Thermal Transfer Value (OTTV) of the wall was calculated by ECC Ho Chi Minh at 45.05 W/m2, a reduction of 30% compared to the EEBC requirement (of 60W/m2).
Roof – Terrace
The roof of the building has five layers made up of:
+ Tar paper (1mm)
+ Corrugated iron roof (3 mm)
+ Concrete slab (7cm)
+ Glass wool (3cm)
+ Gypsum Ceiling

Over Thermal Transfer Value (OTTV) of the roof is calculated by ECC Ho Chi Minh at 20.94 W/m2, a reduction of 16% compared to the EEBC requirement (of 25W/m2).

HVAC

Centralised air conditioning
Installation of a Variable Refrigerant Volume (VRV) AC system that includes 15 outdoor units with a capacity of 44 kW each and COP of 3, a 5.6% improvement compared to the EEBC requirement (of 2.84).

Lighting

Usage of energy efficient lamps
250 (3W) LED lamps are used in lobbies and guest rooms.
3,500 (7W) Compact fluorescent light lamps are used in restaurant, gym room, guest rooms and public areas.
Lighting Power Density (LPD) is 4.8 W/m2, a reduction of 56% compared to the EEBC requirement (11 W/m2).

Building Loads

1. Water pumping system
Installation of VSDs for three (3.75 kW) water pumps to control operation more efficiently.

2. Lift
Installation of VSDs for four (18 kW) lift motors to ensure more efficient operation.

Monitoring
Installation of sub-meters to precisely monitor energy consumption of AC systems, pumps, lifts … to guestrooms, a restaurant and kitchen.

Maintenance
Implementation of a preventative maintenance , repair and replacement plan for each family of equipment.
Qualified Technical Staff (12 members) in several fields such as eletricity, electronics, plumbing,…etc
They perform 8,000 hours of maintenance works per year to ensure continuous operation for the hotel and provides a high level of customer services.

Training
Organisation of training courses to raise staff awareness about efficient energy usage.
Staff training on AC, lighting and pumping systems and operating modes approximately 60 hours/person/year.
