Hatton National Bank's (HNB) Jaffna Green Building, the state of the art bank building which maximizes resource efficiency, won the 'Silver Flame Award' in the Medium Scale Commercial Buildings category at the prestigious Sri Lanka National Energy Efficiency Awards (SLNEEA) 2014 held at BMICH recently.
This is the fourth consecutive year that HNB has been recognized for energy efficient buildings with HNB Towers, Nittambuwa and Kalmunai buildings rewarded in 2011, 2012 & 2013 respectively.
HNB Jaffna Green Building, commissioned in May 2013, accommodates Jaffna Metro Customer Centre, Northern Regional office, a private banking floor and a fully equipped training centre. It set several precedents in the Northern Province as the first building to employ integrated sustainable services monitored by a BMS system, the first building to have a state of the art 260 seat auditorium and the first building to have elevated gardens along with a solar sensitive automated louvre system.
Architecturally, the landmark building established a new post-war regional architecture trend which went beyond the Dravidian architectural style popular in Jaffna by carefully conserving the spatial characteristics of local domestic architecture but moving forward with an ultra modern design on par with any building in the western world.
The double screen on the eastern and western sides of the building reflect glare and excess sunlight while the thick vegetation of vertical landscaping filters polluted air. The Chill water Central Air Conditioning System consists of a high efficiency water cool chiller connected with variable temperature and variable water flow while chill water piping system and air side includes pressure independent variable air volume (VAV) terminal boxes.
Furthermore, a sophisticated solar shading system enables the building to react to changes in the weather and the sun's position to optimize the flows of heat and light through the façade. This, in turn, reduces heat gain and glare and enhances the use of natural daylight, reducing the building's operating costs.
A 15kVA Roof mounted solar PV system with net metering facility generates 1,800 kWh of electricity and as a result electricity consumption in the building has been reduced by 15%. A separate overhead tank which collects rain water from the roof is made use of to water the plants while waste water is also treated and used for the same purpose.
SLNEEA is an annual event conducted by Sri Lanka Sustainable Energy Authority of Ministry of Environment and Renewable Energy and the awards are given in recognition of contribution to reduce energy usage through energy management efforts.
