2014.118 (Obsoleted) IA 2 Performance Enhancement

2018.147 (Revision 2) EU P1, EU 1 and EU2 (All NB, EB, BI Versions) - Compliance of Building Energy Code & Energy Audit Code and Baseline Criteria for Energy Simulation - Clean Version / Version with Track Change

2019.154 (Revision 1) EU 10 Testing and Commissioning - Clean Version / Version with Track Change

(EU) - New
a. Process load is defined as "the load on a building resulting from the consumption or release of energy consumed in support of a manufacturing, industrial, or commercial process other than conditioning spaces and maintaining comfort and amenities for the occupants of a building”.
b. Process load could be excluded from the energy simulation.

EU 1 and EU 2, For BEAM Plus New Buildings Version 1.1 and 1.2, what are some of the examples which could be classified as "process load”?

"Process load” typically includes the load on a building resulting from the consumption or release of energy consumed in support of industrial laundry washing and drying, commercial cooking devices, industrial waste water treatment, and other manufacturing, industrial, or commercial process.

(IEQ) - New

Yes. Water seal traps are required for all floor drains located in kitchen, bathroom, plant room, meter room and refuse storage to reduce the potential for transmission of harmful bacteria viruses and odours.

By common practice, the water in the trap may dry up through evaporation unless water is replenished. Therefore, the following approaches should be considered for the maintenance of water seals:

i. Divert some of the waste water from a sanitary fitment to the U-trap of floor drains;

ii. Provide the declaration letter from building owner / property management company to demonstrate manual water refilling will be conducted on regular basis for floor drains outside domestic flats; and

iii. Provide notification, such as resident’s handbook, pamphlet, tenant handbook and notices to demonstrate that building users are encouraged to conduct regular manual water refilling for floor drains inside domestic flats.

For the second Bonus credit, it could be achieved if the IAQ Certificate covers the majority of development, which means at least 60% of the project’s gross floor area (including tenant areas) in the past three years.

One credit can be achieved under IEQ 22 if the Applicant provides at least 3 different enhanced provisions as stipulated in the "Recommended Design Requirements” of the Design Manual - Barrier Free Access 2008. To facilitate for the assessment, the Applicant is recommended to provide evidence in the form of report prepared by a suitably qualified person (e.g. architects, landscape architects or building surveyors).

(SA) - New
SA 14, For BEAM Plus New Buildings Version 1.1 and 1.2, please clarify the assessment criteria if the project proponent intends to only provide a space (e.g. A/C platform) for the future installation of A/C equipment?

The objective of this credit is to encourage proactive design techniques to reduce the nuisance caused to neighbors by noise from building services equipment. Since the credit assesses mainly on the location and disposition of the building services equipment, the credit shall be applicable even if the project proponent only provides a space for the future installation of A/C equipment.

To demonstrate the compliance of this credit, the Applicant shall provide a noise assessment calculation, with the assumption of a hypothetical A/C equipment with a sound pressure level of 55dB(A) being installed at the space designated for the future installation of A/C equipment.
