An energy performance contract (EPC) can guarantee energy savings for an existing building without an initial financial outlay.
To help building owners overcome the initial financial barrier to retrofit their buildings, the Singapore Green Building Council (SGBC) has collaborated with the Building and Construction Authority (BCA) to develop a standard EPC template for building owners and EPC firms to use. The EPC template was developed in consultation with several established EPC firms and building owners. The standard template assists in accelerating the retrofitting process by clearly spelling out the key conditions of contract for both the building owner and the EPC firm so that building owners can better focus on the critical component in any EPC: the amount of energy savings guaranteed.
The EPC template complements the Building Retrofit Energy Efficiency Financing (BREEF) scheme by BCA which offers financing to building owners, Management Corporation Strata Titles (MCSTs), Special Purpose Vehicles and EPC firms for energy efficiency retrofits.
In an EPC, the EPC firm will guarantee specific energy savings for the building over a set period of time, either in monetary terms or a savings percentage. The EPC firm can either provide financing to undertake all the necessary works to complete the retrofit of the building, or the building owner can finance the retrofit. For the first option, the building owner will not need to incur an initial financial outlay to start saving energy. In both cases, the cost of these works will be offset by the energy savings as a result of the retrofitting.
“With this standard template, building owners can ease into building retrofit projects, allowing their buildings to become more energy efficient, with a healthier environment for their occupants. Having in place an EPC will also allow building owners to focus on other aspects of the building, knowing that the building’s energy efficiency and performance is in the hands of professionals,” said Mr Chia Ngiang Hong, President of SGBC.
As buildings present a tremendous opportunity to reduce emissions and mitigate the effects of climate change, this new EPC template is part of SGBC’s commitments made during Buildings Day at COP21 in Paris on 3 December 2015 to drive change and market transformation for green buildings.
“As Singapore remains committed to reduce its emissions through its Intended Nationally Determined Contributions, retrofitting existing buildings through an energy performance contract can lower the carbon emissions intensity of buildings and create a more sustainable and greener built environment,” Mr Chia added.
In the latest BCA Building Energy Benchmarking Report 2015, a study on 83 existing buildings which are certified to have met the Green Mark Gold rating or higher, showed that retrofitting existing buildings can save up to $41 million annually.
“There is a strong business case to retrofit energy inefficient buildings. The EPC provides a market solution to help building owners achieve energy savings and it has been gaining popularity over the years. It is now timely to launch the standard template contract, putting together the best practices. We hope that this will inspire confidence in building owners to make the decision to embark on energy-saving initiatives,” said Dr John Keung, CEO of BCA.
Sim Lim Tower, Ngee Ann City and Treetops Executive Residences are proof of older buildings that have gleaned tremendous benefit from EPCs.
36-year old Sim Lim Tower has achieved 41 percent savings in electricity bills (excluding tenants) with average monthly energy savings of approximately 86,000 kWh since the retrofits were completed in March 2015 under an EPC arrangement.
Mr Lee Ong Chun, Chairman of MCST of Sim Lim Tower, is satisfied with the results of the EPC retrofit: “The retrofit has improved our building’s energy performance, efficiency and occupants’ comfort. In achieving the BCA Green Mark GoldPLUS Award, the entire exercise has added value and enhanced the image of our building. The EPC firm can help to oversee the efficiency upkeep of the retrofitted works to ensure the same efficiency is maintained at all times, hence sustaining long term energy savings.”
25-year old Ngee Ann City, an iconic building along Orchard Road, is expected to enjoy estimated energy savings amounting to more than 20 percent of electricity bills (excluding tenants) or equivalent to more than six million kWh per year through its energy efficiency retrofits.
Mr Eric Chan, General Manager of Ngee Ann Property Management Pte Ltd, said: “Under the EPC, energy savings generated will be sufficient to pay for these retrofits over the term of the contract. After the contract ends, we will still continue to enjoy energy savings and at the same time, be able to do our part to protect the environment by reducing our carbon footprint. The retrofits also enhance the building asset in terms of its value. Any prospective buyer is willing to pay more for an energy efficient building as the operating expenses will be kept to its minimum.”
Treetops Executive Residences, a 16-year old residential building, has reaped energy savings of 52 percent after its retrofit.
“By having an EPC with a professional vendor, the energy savings and measures that have been proposed can be constantly measured and guaranteed,” said Mr Tay Hock Soon, General Manager of Treetops Executive Residences. “The team can also give professional advice on how the targets can be achieved and ensure that the improvement in energy efficiency is sustained in the long term even upon completion of the retrofits. As the expert in this area, the EPC firm can also advise on new and better green initiatives that tap on the latest technology advancements to push for greater sustainability. This green retrofit has also helped us to anchor our brand position as an eco-friendly building in an increasingly competitive market.”
The standard template EPC will be available for purchase from SGBC in early 2016. EPC firms certified under SGBC’s Singapore Green Building Services (SGBS) labelling scheme will also use this contract in their EPC projects.
Mr Lim Fatt Seng, managing director of SGBS-certified Comfort Management Pte Ltd and the project lead for the EPC template, is confident of the document’s utility to the industry, “This standard template comes at an opportune time as building owners are increasingly looking for ways to improve the efficiency of their existing buildings especially older buildings. With this template, there will likely be a greater and faster take-up for EPC projects, which will benefit building owners, the occupants and our future generations.”
