MAN-3 BUILDING TUNING

Technical Clarification

Vertical Transportation

 

Technical Clarification Number

MAN3-T-OB1-2122

Guidance
2017-11-07

Lifts/Escalators are a part of Man 3 as per MAN2 -T-OB1-1562; however in some instances lifts have no adjustable set points which means they are static and cannot be altered during the tuning process. Therefore, the Vertical Transportation Building Tuning Requirements can be regarded as Not Applicable in this instance for some projects.

Projects are to demonstrate that the lifts have no adjustable set points in order for them to be excluded from the Man 3 requirements.

Guidance on building services / sub-services included within the scope of Man-02 and Man-03 - UPDATED

Technical Clarification Number
MAN2 -T-OB1-1562

Guidance
2016-08-25

Please refer to the 'Man-02 and Man-03 Supplementary Info Document - UPDATED' attached (below), it shows which services are required to be addressed under both the Man-2 and Man-3 credits, and for Man-2, shows which ASHRAE / CIBSE documents are applicable to each in terms of the credit criteria. Where no suitable ASHRAE / CIBSE document is available, the project team’s ‘Nominated Commissioning’ applies. Please note further guidance on ‘Nominated Commissioning’ is given below the table in the document.

Technical Clarification

Building Tuning TC pertaining to Roles & Responsibilities 

Technical Clarification Number
MAN3-C-OB1-1043

Guidance
2015-09-17

The GBCSA acknowledges that some circumstances make it prudent that a different party to the original installer or design consultant be responsible for particular aspects of the building tuning scope: e.g. adjusting of set points or controls should feedback from the monthly tuning indicate that this is necessary and the facilities manager has been trained and is capable to make these adjustments. This is acceptable as long as there are two parties involved, one carrying out the duties of the of the installing party and one carrying out the duties of the design team party. This is to ensure that there is a continuation of the design intent in the building tuning process so that changes made are still within that design intent, but performed to adjust the particular system to the actual occupant’s habits or variation in climatic conditions by a party with sufficient knowledge or experience of that system to carry it out successfully.

Project teams may choose to split these responsibilities on condition that the following documentation is submitted in addition to the rest of the documentation requirements:

  • Description of the split in scope and the related responsibilities of the parties involved (both from a design perspective and an implementation perspective demonstrating that all aspects of the credit criteria are being met – e.g. via a responsibility matrix
  • Short motivation as to why the particular scope is being split
  • Demonstration that the additional member is suitably qualified, experienced or trained to undertake the designated scope
  • Demonstration that sufficient information has been handed over by the relevant party initially involved to the new party taking the tuning responsibility 
  • Description of what activities related to re-commissioning are required for this scope and who will carry it out, and that this party is suitably qualified, experienced or trained to undertake the designated scope.

The above scope is required to be undertaken for each system where new parties will be involved.

Technical Clarification

Simple Domestic Hot Water Systems

Technical Clarification Number
MAN3-T-OB1-0797

Guidance
2014-05-09

The project team’s proposal for excluding from the credit requirements minor domestic hot water systems that have no adjustment barring thermostats and have no timer settings is approved.

The GBCSA notes that the said DHW system may be excluded from compliance requirements of the Man-3 credit for the following factors:
• The scale of the DHW system (200 litre cylinder with electric element and solar collector) is not highly significant in terms of overall building energy consumption
• Provided the system does not operate on timers which may require adjustment based on occupancy, there is no adjustment for seasonal or occupancy variation

Alternative Documentation

Technical Clarification Number
MAN3-T-OB1-764

Guidance
2014-02-14

This email pertains to the Technical Clarification (TC) submitted for the Man-2 Commissioning and Man-3 Building Tuning credits, seeking approval to submit alternative documentation (extracts from building contracts) for the Man-2 and Man-3 credits in place of ‘Extracts(s) from the Commissioning Specification’ and ‘Extract(s) from the Specification(s)’.

The CIR request is conditionally approved. The approval of this CIR is thus contingent on the following:

All the information required to demonstrate compliance with the credit criteria in both the ‘Extracts(s) from the Commissioning Specification’ and ‘Extract(s) from the Specification(s)’ for Man 2 and Man 3 respectively is included in the proposed alternative documentation (i.e. extracts from the building contract).

Please note that the other documentation requirements stipulated in the Green Star SA – Office v1 Technical Manual must still be adhered to.

Note that this Technical Clarification will be uploaded to the TC, CIR & Errata database available on the GBCSA website.

• Optimisation of time schedules to best match occupant needs and system performance; and
• Alignment of the systems’ operation to the attributes of the built space they serve.

Credit Interpretation Request

Building tuning period commencement

Credit Interpretation Request Number
MAN3-C-OB1-0274

Ruling
2011-05-30

The Credit Interpretation Request (CIR) seeking approval to commence the 12 month building tuning period, as prescribed in Man-3 Building Tuning Credit Criteria in the Green Star SA Office v1 Technical Manual, at a date beyond the practical completion date of the Green Star SA project, is conditionally approved.

The CIR Review Panel holds the opinion that it is likely that some Green Star SA projects will not be in a position to commence the 12 month building tuning period immediately upon practical completion for reasons which may limit the beneficial outcomes intended (e.g. speculative development with low occupancy levels etc.). It is therefore acceptable that the 12 month building tuning period (in accordance with the Green Star SA Office v1 Technical Manual) commences at a date after the Green Star SA project’s practical completion date. However the 12 month building tuning period must commence within 2 years of the practical completion of the Green Star SA project (in acknowledgement of Green Star SA ‘Eligibility Criterion 4: Timing of Certification’.
