[Music] hello everyone my name is evan logan senior sustainability consultant at cads group and today i'll be giving a brief introduction on applying the performance solution process with the much needed introduction of more stringent energy provisions with new technology and products on the market with the increased uptake of best practice industry benchmarks we are coming across more diverse and technical solutions for compliance and the increased use of performance solutions as part of its efforts to encourage the increased and competent use of performance solutions the abcb has produced a number of guidelines and educational materials to support performance solutions use more recently a new provision a 2.2 section 4 the process for developing and documenting performance solutions has been included into the national construction code it has been introduced into the ncc 2019 amendment one with an implementation date of the first of july 2021 this instructional video will provide background information on the application of performance solution with respect to energy efficiency it will outline the methodology for documenting our performance solution in line with aid 2.2 section 4 and it will apply it to an energy efficiency case study firstly some background information on the use of performance solutions to meet performance requirements performance solutions are satisfied by one of the following a performance solution a deemed satisfied solution or a combination of the two a performance solution our focus for today is achieved by demonstrating compliance with all the relevant performance requirements or demonstrating that the solution is at least equivalent to the deemed to satisfy provisions so when applying this to section j energy efficiency provisions on your screen you can see an example of applicable performance requirements these performance requirements can be achieved by either a performance solution using a verification method as the assessment method as you can see on the screen the performance solution must be shown to comply with the relevant performance requirements through one or a combination of the following assessment methods evidence of suitability in accordance with part a5 of the governing requirements that show the use of materials products plumbing and drainage products form or construction or design meets the relevant performance a verification method including the verification methods provided in the ncc for example jv3 verification using a reference building or other verification methods accepted by appropriate authority that show compliance with the relevant performance requirements expert judgment and comparison with the deemed satisfy solutions are two other assessment methods the process for undertaking a performance solution in line with provision a 2.2 section 4 involves the following steps firstly you want to prepare a performance-based design brief this is in consultation with relevant stakeholders and the appropriate authority so it may include the architects service consultants building certifiers to client or relevant experts in a specific field for example energy and fire the brief is to include a minimum of three sections a scope of works for the performance-based analysis the technical basis for analysis and the acceptable criteria of the relevant performance solution as agreed by the stakeholders once the brief has been prepared you want to carry out analysis as documented in the brief and then evaluate the results against the acceptance criteria in the brief and finally we want to put this into a report that includes at least all performance requirements and deemed to satisfy provisions identified in the brief and identification of all assessment methods used the details of step one to three of the brief as seen on the screen and confirmation that the performance requirements have been met and details of any conditions or limitations if they exist regarding to the performance solution let's now apply this to a case study so be using a simple petrol station in south australia ncc climate zone 5.
The consultant group undertook a section jai review of the design of a proposed petrol station in australia south australia in ncc climate zone 5 an initial deemed to satisfy assessment has deemed the floor as non-compliant with j1.6 floors the required total r value of the floor to comply is two the current r value when applying table two b r value in soil in contact with the floor of specification 1.6 subfloor thermal performance is 1.4 so the floors are deemed to be non-compliant the stakeholder group being the architect the client service consultants sustainability consultant and building certifier meet to determine if the uninsulated floor has a significant impact on the heating and or cooling loads of the building compared to another building with deemed to satisfy elements to things such as the walls roof and glazing the stakeholder group agree to undertake a whole building model to test the impact of the insulated floor has on the petrol station in comparison with other building elements the stakeholder agree group agree that all other deemed satisfied provisions can be met the group agree on undertaking a thermal comfort analysis to make sure thermal comfort is achieved a predicted main vote or a pmv of negative one to plus one is to be achieved across not less than 95 of the floor area of all occupied zones for not less than 98 of the annual hours of operation of the building so step one we want to prepare a performance based design brief which includes a scope of works the scope of works proposed by the stakeholder group is to analyze undertake analysis to test whether the heating and cooling lights for the proposed building with no floor insulation is less than that of a reference building with them satisfied compliant walls ceilings floors and windows it is proposed that the performance solution is achieved by demonstrating the solution is at least equivalent to the deemed to satisfy provisions and as such comparison with the deemed to satisfy provisions is used as the assessment method we then identify the technical basis for analysis in this case the consultant intends to utilize ies be energy modeling to calculate the annual load of the building which has been approved for the use for this purpose being compliant with ashrae 1400 2007 best test the modeling software will be used to demonstrate equivalency with section j building fabric when with added compliance for additional deemed satisfied provisions not covered by a model solution including for general thermal construction compliance with j 1.2 and the building ceiling of the building to comply with j3 all other provisions not covered by the modeled solution including j5 to j8 will be designed compliant with a dts solution we then identify the criteria criteria for acceptance that is what needs to be met to demonstrate either compliance with all the relevant performance requirements or the solution is at least equivalent to attempt to satisfy solutions in this instance we provide drip propose that under 2.2 section 1 the performance solution is achieved by demonstrating the solution is at least equivalent to the dense satisfy provision and the remaining clauses in a 2.2 when we undertake the analysis the results of the load analysis undertaken through ies software being on your screen modeled inputs are pers specification jvb and gvc we then evaluate the results identified in step 1b the technical basis for analysis against the step c acceptance criteria in the performance based design brief the analysis demonstrates the difference in performance between the proposed building load and the reference building ie dts fabric allows for a quantifiable comparison of the building's fabric performance as a whole in a different comfortable levels are achieved throughout the year in addition to this the following theme to satisfy semester assessment was achieved to reduce limitations in the software this includes for general thermal construction j 1.2 and the building ceiling of the building to comply with j3 the building services to be designed in accordance with deemed to satisfy provisions of parts j5 to ja we then compile the data and create our report which should include as a minimum all performance requirements and deemed to satisfy provisions identified as applicable identification of all assessments methods used record of details from the brief relating to steps a to c just described before confirmation that the performance requirements have been met and details of conditions of limitations if any exists regarding the performance solution comfort may have been impacted and the group agree on undertaking a thermal comfort analysis to make sure thermal comfort is achieved a predicted mean vote of negative one to plus one is to be achieved across not less than 95 percent of the four of all occupied zones for not less than 98 of the annual hours of operation of the building in summary the process for undertaking a performance solution in line with provisions a 2.2 section 4 involve the following steps one a performance-based design brief this is in consultation with relevant stakeholders being the architect service consultants or client and involves the following a scope of work the technical basis for analysis and the acceptance criteria of a relevant performance solution two we want to carry out the analysis as per the proposed brief three we want to evaluate the results against the acceptance criteria of the brief and four we want to prepare our final report in closing there is further supporting resources including a guidance document and handbook which are available on the abcb website in the resource library thank you for your time [Music]
