FAQ Q4. EU 1, For BEAM Plus NB / EB v1.1 and v1.2, Do I need to include Fan energy in the energy analysis calculation? Ventilation fan energy for bathrooms and kitchen in residential units and club house, plant rooms, RS&MRR/RS&MRC and car park including the jet fans should all be included in the calculation where applicable. Input power of motor should be used instead of absorbed power of fan. (Released on 9 March 2015)

24

Q1. EU 1, What type of Baseline Model setting for office building should be used in energy simulation? Referring to the BEAM Plus templates, it is stated that the use of the simulation method of either Performance-based Building Energy Code or ASHRAE Standard 90.1-2007 for commercial building is acceptable to BEAM Plus. The selection to use which simulation method is opened for the BEAM Pro to choose. Q2. EU 1, Will passive energy saving strategies contribute to the CO2 emission reduction calculation? The passive energy saving strategies can contribute to the CO2 emission reduction calculation. Initiatives such as natural ventilation and natural daylight would also be counted in EU1. Q3. EU 1, What kind of software is acceptable for BEAM Plus Energy modeling? In principle, BEAM Plus Assessment would accept the use of most of the building energy analysis simulation software listed in the Appendix II of the EMSD Performance-based Building Energy Code 2007 Edition for the energy simulation required in BEAM Plus. However, the Technical Review Committee might review the acceptance of any other software that are not in the list (Appendix II) but embrace those simulation general requirements as highlighted in Appendix G2 of the Appendix G Performance Rating Method of ASHRAE Standard 90.1-2007. The applicant will have to submit verification report of the software to prove their suitability for the purposes. Q4. EU 1, For BEAM Plus New Buildings / Existing Buildings Version 1.1 and 1.2, Do I need to include Fan energy in the energy analysis calculation? Ventilation fan energy for bathrooms and kitchen in residential units and club house, plant rooms, RS&MRR/RS&MRC and car park including the jet fans should all be included in the calculation where applicable. Input power of motor should be used instead of absorbed power of fan. (Released on 9 March 2015) Q5. EU 7, Is table 8.7 at EU 7 applicable to outdoor units of split-type air-conditioning units? All dimensions specified in Table 8.7 in current BEAM Plus Ver. 1.1 and should be applicable to the outdoor units of split-type air-conditioning units except dimension J and K.
