Centre for Energy (ACE) places emphasis on the implementation of CCT to curb the release of carbon dioxide (CO 2 ), sulphur dioxide (SO 2 ) and nitrogen oxide (NO) into the atmosphere. Making the Region’s Buildings Energy Efficient (Source ASEAN POST, December 26, 2018) Member states of the Association of Southeast Asian Nations (ASEAN) intend to reduce regional energy intensity by 20% by 2020 and 30% by 2025, compared to 2005 levels. According to the ASEAN Centre for Energy (ACE), the region is on track to reach its goals as energy intensity levels have seen a downward trajectory between 1995 and 2014. Nevertheless, future projections like these still require concentrated efforts to ensure that they are realised. A constructive method to reach this goal would be to improve energy efficiency. Energy efficiency is an important indicator that environmental and economic challenges are being met in a rapid and cost-effective manner. ensuring that air conditioners are installed with an energy saving inverter which reduces power consumption. This is just one of many ways buildings can be made to be more energy efficient. According to recommendations by the International Energy Agency (IEA), buildings in this region should comply with building energy codes and minimum energy performance standards (MEPS). They should also aim for net-zero energy consumption and strive to improve the energy efficiency of building envelopes, systems, and critical building components. The most effective way of improving energy efficiency in buildings is to engage with energy service companies (ESCOs) which provide a broad range of energy solutions. These services include the designing and implementation of energy savings projects, retrofitting, energy conservation, energy infrastructure outsourcing, power generation and energy supply, and risk management. ESCOs have been adopted widely especially in more developed ASEAN states like Singapore, Malaysia, Thailand and Indonesia and are fast becoming a popular financing vehicle across ASEAN. Improving energy efficiency of buildings Financing energy efficient buildings Buildings are an important piece of the energy efficiency puzzle. According to the United Nations Environment Program (UNEP), buildings are responsible for upwards of 30% of global greenhouse gas (GHG) emissions. Moreover, more than 50% of the planet’s new buildings are constructed in Asia yearly and the building sector constitutes an estimated 25% of overall energy consumption. Earlier this year, it was reported that Southeast Asia was faced with a “cooling crisis” as more people are cranking up their inefficient air- conditioning systems. This has had a negative knock-on effect on the environment as the electricity used to power these systems is provided by coal-fired power stations. While it is true that one could just switch off the air-conditioner, the region’s hot and humid weather would make that an unpopular decision in most office buildings. The solution then lies in ensuring that electric devices run efficiently on as little electricity as possible. In this case, by One thing to keep in mind is that any effort to improve energy efficiency in buildings will incur additional costs. The advantage is, thanks to the energy saved, building owners or tenants will save more money in the long term. Installing energy efficiency systems opens up bountiful opportunities for investment. According to a report by the United Nations (UN) and Singaporean financial service provider, DBS, residential and commercial building sectors are estimated to have investment opportunities of USD88 billion and USD64 billion, respectively. The returns on such projects are incredibly attractive – at times exceeding 20%. While energy efficiency projects can be financed completely by private financiers, the Government can also play a role. For example, in Malaysia, the Energy Performance Contracting Fund helps finance projects with a target financing size of no higher than USD3.8 million and a tenure of no longer than seven years. 71
