National Cinema Center, is a three-storey building, composed of 10 cinema rooms, a fast food and an entertainment area. The building was awarded the consolation prize for the Refurbishment Building category in the Energy Efficient Building Contest organized by the Ministry of Industry and Trade in 2013. Many energy saving solutions have been applied such as a solar heat water system, louvers and reflective films.
Third Party Verified: No

Methods of data collection: interviews with manager and data collection via email.
The building main entrance is orientated to the northwest direction which is unfortunately not the most favorable orientation.
The window to wall ratio (WWR) is 30%. According to the Energy Efficient Building Code – Building Envelope Guideline (EEBC), WWR must be between 30%-50% (EEBC 2013).
All windows are double-glazed. In addition, a reflective film was installed on the outside of west façade, which helps reducing the cooling load for AC systems.
Light – yellow painted walls allows a high solar reflection capacity. It helps to reduce the thermal inertia of the building.
The louver system is made of aluminum plate thickness of 5 cm which to prevent solar radiation from entering the building directly.
Solar water heating panels are used to collect solar energy but also contribute to reduce solar radiation on the roof surface.
Centralised air conditioning
Installation of a Variable Refrigerant Volume system with a capacity of 8.93 kW each and COP of 2.8, a 17% improvement compared to the EEBC requirement (of 2.4).
Control of lighting
Installation of a lighting control system to better controlled operation by following a predefined schedule and avoid unnecessary energy consumption.
A lighting control system
Hot water system
Installation of a solar water heater with a capacity of 100 liters/day, which provides 80% of the hot water for the fast food area.
Commitment to energy efficiency policies
The Board of Director makes decisions to issue official documents to guide energy saving procedures.
Installation of sub-meters to precisely monitor energy consumption in the fast food and entertainment areas.
Implementation of a preventative maintenance, repair and replacement plan for equipment.
There are 12 Qualified Technical Staff in several fields such as eletricity, electronics, plumbing,…
They perform 15,000 hours of maintenance work per year to ensure continuous operation for the building.
Organisation of training courses to enhance skills in specific fields, including efficient energy management and operation, labor protection and fire protection
