The Glass Explorer was developed to enhance the process of exploring and selecting glass products that suit project requirements.

Conventionally, available products are shared via large spreadsheets or tables. Searching data in this manner is laborious, particularly when there are multiple thermal, optical, and aesthetic goals.

Inhabit has adopted a highly visual and responsive workflow to demonstrate the market availability of glass products to:

. Simplify the process of glass product selection via key thermal, optical, and aesthetic goals
. Easily contrast specifications between glass products
. Reveal a wider range of glass suppliers and product lines

The DTS Facade Designer was developed by Inhabit in accordance with Section J (2016) – Part J2.4 Glazing, Volume One (Method 1).

It aims to demonstrate energy efficiency Deemed-to-Satisfy Provisions for façade design and applies to Class 2, 3, 6, 9c (aged care) or Class 4 parts of a building in Climate Zones 1 – 8.

As opposed to the standard approach, where an Excel spreadsheet is downloaded from the ABCB website and completed by an engineer or external consultant, DTS Facade Designer is an online tool to rapidly test your façade design strategies against compliance. Say goodbye to the DTS Calculators!

Via a simple and intuitive user interface, users gain an understanding of the influence of key parameters to:
. Retain Architectural Intent
. Assess against NCC Section J 2016
. Design Value Management

Via a simple and intuitive user interface, users gain an understanding of the influence of key parameters to grow DTS design strategies as design ideas develops from early stage through to detailed design.

Such key parameters include:

.  System Glazing U-Value
.  System SHGC
.  Frame U-Value
.  Glazing Window to Wall Ratio
.  Glazing Frit Density and Coverage
.  Horizontal Shading

It is intended that the DTS Facade Designer is simple enough to be used by all of those involved with or interested in the design of buildings.

In developing the ETTV Façade Designer Inhabit worked within the parameters defined in the Singapore Building and Construction Authority Guidelines on Envelope Thermal Transfer Value for Buildings Version 1.01, 2004.

ETTV Façade Designer is an online tool that demonstrates Envelope Thermal Transfer Value (ETTV) performance and compliance for Green Mark for BCA Green Mark V 4.1 and BCA Green Mark 2015.

ETTV Façade Designer’s simple and intuitive interface enables designs to be investigated from early stage through to detailed design.

Developed with Architects in mind, users gain an understanding of the influence of key parameters to:

. Retaining Architectural Intent
. Assessing against the proposed changes to ETTV within Green Mark 2015
. Design Value Management

Developed with Architects in mind, users gain an understanding of the influence of key parameters to grow ETTV design strategies as design ideas develop and mature.

Such key parameters include:

. Glazing U-Value
. Wall U-valu
. Glazing Shading Coefficient (SC)
. Glazing Window to Wall Ratio
. Inclination of façade
. Glazing Frit Density and Coverage
. Horizontal Shading, inc louvres
. Vertical Shading, inc louvres
. Results are displayed clearly and respond to parameter changes instantly.

Air leakage is the infiltration and exfiltration of air through a building envelope or component due to imperfections in its construction. It takes place, for example, through cracks around doors, windows, structural penetrations, service entries and porous constructions. Inhabit has developed the Air Permeability Designer to demonstrate the implications of air permeability goals for building outcomes.

An air leakage test is carried out by mounting a fan (or fans) in a suitable aperture within the building envelope to either depressurise or pressurise the building. An internal/external pressure difference is created across the building envelope, typically aiming for a with a maximum difference of 50Pa.

This quick and simple tool aims to highlight the:

. Differences between industry standards and Green Star best-practice permeability rates
. The extent of testing equipment required
. Implications of air permeability rates for HVAC systems

Inhabit Bubble represents the thoughts, ideas and experience across our network of discipline experts. Our focus is the ongoing improvement of building design and construction.  Part of this is the sharing of knowledge with our peers – we have developed a series of in-house tools that we use ourselves and we think that you could gain the benefit of our collective experience too.

All tools are free to use.

With a focus on upfront design information, these free to use tools represent part of a series of R&D projects, so watch this space for updates and more.
