introduction
The Energy Smart Buildings Scheme, developed by the Energy Sustainability Unit (ESU) of the National University of Singapore (NUS) and the National Environment Agency (NEA), aims to promote the active management of energy use by according recognition to buildings that are ranked in the top band of the total building cohort using an energy efficiency benchmarking system. Presently, the Scheme is ready for office buildings. |

benefits
Saves Energy Costs |
|
a) |
The energy bill is typically the building’s single largest operating expense and any energy-inefficient system would only increase the energy costs. In working towards attaining the Energy Smart Office Label, building owners and managements would save money by actively managing the energy efficiency performance of their buildings. |
|
|
|
|
|
|
|
|
| |
|
b) |
Energy efficiency improvements are easily tracked by comparing the building’s performance against the national reference. |
|
|
|
|
|
| |
|
Healthy Indoor Environment |
|
Building occupants are assured of a healthy and comfortable environment, as the performance in areas such as indoor air quality, illumination, thermal comfort and ventilation rates are measured to ensure that the relevant indoor environmental quality standards are met before the Energy Smart Office Label is awarded. |
|
|
|
| |
A Comprehensive System |
a) |
The Scheme provides resources such as a national benchmarking system, an online assessment tool and technical guidance on various systems performance for building owners’ and managements’ easy adoption and use. |
|
|
b) |
Building owners and management of office buildings that are not ranked in the top band would also find the Scheme very useful. The Scheme offers performance indicators and energy efficiency targets as management tools for performance tracking and improvements. |
