ETTV Façade Designer released to Singapore Market
With the Inhabit team thinking up creative ways to make the design process easier, we’ve set our sights on the ETTV process as a foundation to access a more efficient and cost effective design process.
Available for Free, Inhabit are excited to release the ETTV Façade Designer to the Singapore design and construction industry.
With much of the Singapore design community needing to undertake ETTV assessments throughout the design process, the ETTV Façade Designer aims to minimise the time and energy spent on a process in an intuitive and effective way that yields measurable results quickly.
Taking users through an intuitive process, with both simplified and detailed interfaces, it is now possible rapidly assess your façade design strategy against ETTV requirements in as little as 60 seconds!
Inhabit’s Regional Manager for Singapore, Gautam Bhasin comments:
“ETTV compliance presents design challenges for architects, builders and suppliers in Singapore’s building and construction market. Recently introduced benchmarks mean that ETTV has to be considered more closely when undertaking any design decisions that influence the façade outcome. The release of the ETTV tool by Inhabit for professionals to use freely is an exciting step for our industry, and I expect the assistance in day to day calculations and improved façade design by industry to start off the next chapter in Singapore’s building growth.”
2015 saw the The Building and Construction Authority (BCA) launch the ‘Green Mark for New Buildings – (Non-Residential) 2015’.
Representing the fifth edition of the Green Mark scheme for new buildings, Green Mark 2015 aims to balance sustainability outcomes, with a greater emphasis on:
. Contextual design that incorporates climatic variations more closely
. Energy effectiveness
. A greater focus on health and wellbeing of building occupants
. Supporting Smart Building creation
. A systematic approach to addressing embodied energy and resource use.
Of the proposed changes to Green Mark (2015) from Green Mark (4.1), the approach to reduce air conditioning energy consumption due to thermal heat gain through the building façade has seen increased focus through the adoption of the more stringent Envelope Thermal Transfer Value (ETTV) target. Continuing to set the reference for an sustainable building design, the maximum façade performance (prerequisite) requirements for ETTV have now been reduced by 5% (Gold Plus + Platinum) and 10% (Certified and Gold), supported by a new focus on Tropical Façade Performance.
Traditionally, ETTV assessments have been undertaken by practitioners generating spreadsheets using standardised equations. This method of calculation was often inaccessible to Architects, with the glass performance specifications being manipulated to produce ETTV design values.
