EXISTING BUILDING LEGISLATION

BACKGROUND

To achieve a sustainable built environment, it is important to ensure that existing buildings continue to operate efficiently throughout their life cycle. On 01 December 2012,  Part IIIB—Environmental Sustainability Measures for Existing Buildings was introduced to the Building Control Act (Act), requiring building owners to:

  • Comply with the minimum environmental sustainability standard (Green Mark Standard) for existing buildings;
  • Submit periodic energy efficiency audits of building cooling systems; and
  • Submit information in respect of energy consumption and other related information as required by the Commissioner of Building Control.

These measures will help building owners to benchmark their current building operations, achieve the minimum efficiency standards required and reap the benefits of the energy efficient systems.


SCOPE AND DETAILS

MINIMUM ENVIRONMENTAL SUSTAINABILITY STANDARD (GREEN MARK STANDARD) FOR EXISTING BUILDINGS

Before 2nd January 2017

The Building Control (Environmental Sustainability Measures for Existing Building) Regulations 2013 shall apply to offices, hotels, retail malls and the mixed of the aforesaid types of buildings:-

  1. having a gross floor area of 15,000 m2 or more;
  2. installing or replacing the central water-cooled / air-cooled chiller(s)

In the case of any mixed-use development, the minimum environmental sustainability standard will be applicable as long as there is any hotel, retail building or office building therein and the GFA of a combination of these parts is 15,000m2 or more. Any mixed-use development which includes any industrial building, industrial retail building, light industrial building, special industrial building, railway premises, port services and facilities or airport services and facilities shall not be required to comply with the minimum environmental sustainability standard.

EXPANSION OF BUILDING TYPES

On and after 2nd January 2017

The Building Control (Environmental Sustainaibility Measures for Existing Building) (Amendment) Regulations 2016 will apply to all buildings with centralised cooling systems and GFA greater than 5,000 m2, when installing or replacing the building cooling system.

Only the following types of buildings will be excluded from the above requirement.

  1. any industrial buildings;
  2. any railway premises, port services and facilities or airport services and facilities;
  3. any religious buildings;
  4. any data centres;
  5. any utility buildings; or
  6. any residential buildings but not including serviced apartments.

Submission Requirement

The Regulations require building owners to achieve a minimum of 50 Green Mark points and meet the pre-requisite requirements, using the scoring methodology as specified in the Code on Environmental Sustainability Measures for Existing Buildings, and such other requirements as may be specified in the Code. Building owners are required to submit to BCA for approval:

  1. a design Green Mark Score for the building including other specified documents before installing or replacing of chillers (major energy-use change) ; and
  2. an as-built Green Mark Score for the building including other specified documents after completing the installation of chillers.

The building owners will have to engage a Professional Mechanical Engineer, to ensure that the overall building design meets the requirements specified in the Code, taking into account the chiller upgrade and other energy improvement works. The major energy-use change must be completed within three years from the date BCA approves the design Green Mark Score.


Plan Fees

A plan fee is required upon submission of the design score. The computation of the plan fee is as follows:

  • $8,900 for the first 15,000m2 or part thereof, and $0.15 for every subsequent square metre (or part thereof), of the gross floor area of the prescribed building

MANDATORY SUBMISSION OF PERIODIC ENERGY AUDITS

The performance of any chiller system will deteriorate overtime if not properly operated and maintained. The aim of the periodic energy audit is to ensure the building cooling system continues to operate efficiently throughout its lifespan, allowing building owners to continuously reap the energy saving benefits. The periodic energy audit has to be carried out by a PE(Mech) or a Energy Auditor registered with BCA. 

With effect from 01 Jan 2014, building owners are required, upon notice from the Commissioner of Building Control, to engage the services of a PE (Mech) or an Energy Auditor registered with BCA to carry out an energy audit on the building cooling system BEFORE making the necessary documentary submission to the Commissioner of Building Control. The energy audit has to be in accordance to the Code on Periodic Energy Audit of Building Cooling System.

The Periodic Energy audit will be applicable to the following group of buildings:

  1. For new buildings whose application for planning permission is submitted on or after 1 December 2010, building owners may be issued a notice:
    1. at any time after the temporary occupation permit (TOP) or certificate of statutory completion (CSC) is issued,; and,
    2. at intervals of not less than three years after the date of the last notice served.
  2. For existing buildings which have undergone a major energy-use change on and after 2nd January 2014 and are required to meet the prescribed Green Mark Standard for existing building, building owners may be issued a notice:
    1. three years after the date of the approved as-built score; and,
    2. at intervals of not less than three years after the date of the last notice served.

ANNUAL MANDATORY SUBMISSION OF BUILDING INFORMATION AND ENERGY CONSUMPTION DATA

From 1 July 2013, building owners are required to submit their building information and energy consumption data annually to BCA. To make this exercise as easy as possible, building owners can enter their information through BCAs new Building Energy Submission System (BESS) using the BESS ID or SingPass from 1 to 31 July 2013.

BCA will be using the data to monitor the energy efficiency of buildings in Singapore and to formulate the national energy benchmark. The benchmarking data will be made available to the building owners so that building owners can pro-actively improve their buildings energy performance and or energy consumption behaviour of occupants and users. This would help improving the energy efficiency of existing buildings and contributing towards meeting improving the energy efficiency of existing buildings and contributing towards meeting the national target of greening 80% of the building stock by 2030.

For information on the submission procedures, please visit https://www.bca.gov.sg/BESS/Default.aspx/.
