Kalwall Translucent Panel System

Kalwall Translucent Panel System

•  Kalwall is a translucent, highly insulating light diffusing building system for walls and roofing

•  Kalwall comprises of fiberglass sheets bonded to a grid core of aluminium I - beams

•  A – External face sheet

•  B – Glass fiber insulation

•  C – Aluminium I-beams

•  D – Internal, shatterproof face sheet

What is Kalwell?

•  Unmatched thermal performance and solar heat gain reduction creates climate stability within the environment that leads to a reduction in HVAC systems useage

•  Natural daylight reduces artificial lighting requirements leading to a reduction of building energy consumption

•  Natural light has a positive impact on health and wellbeing of workers

•  High impact resistance •  Customisable solutions

Benefits of Kalwall

•  Kalwall is a structural translucent sandwich panel that is either 70mm or 100mm thick.

•  I Beams can be solid aluminium or thermally broken to increase the thermal performance of the system.

•  The kalwall panel is encapsulated by an extruded aluminium cill and mullion section to keep it watertight.

•  Panel widths are 1200mm and 1500mm standard. •  The Kalwall panel is the key to several systems available.

Benefits of Kalwall over Glass

“U” value measures thermal transmission through the product USA = BTU / hr . Ft². °F SI (System international) = w / m² . °C R Value measures the Thermal Resistance of the product R Value = m² . °C / w Note: Most imported products will be using the SI “U” value. As the “R” value is the inverse to this value, use the formula 1/U to convert the value. i.e: SI “U” value of 0.52 is “R” 1.9 (1 / 0.52)

“U” value vs “R” value

Face sheets are made with kalwalls unique resins and fiberglass design. Erosion veil barrier is integral to the resistance of fiber bloom and delamination. The face sheets are of full thickness color stability and not a coating.

Why Kalwall?

LED backlighting gives endless options for façade designs

Additional Features

Daylight design is the use of translucent products that allow natural daylight from the sun to emit through the product and into the building. This can be in the form of walls / windows / roofs or skylights. There are a number of benefits of designing with natural light dispersion inside the building including the reduction of energy costs from less artificial lighting and health benefits for occupiers of the building are also improved using natural daylight. Lighting levels and requirements are at the forefront of design priority and the building is designed around it accommodating these parameters.

Daylight Modelling

Computer generated daylight model simulations are the most effective way to design. Multiple scenarios can be generated at the touch of a button. Buildings and openings are modelled based on any time or date within the year to show typical light emitting patterns and real world weather data for a specific site.

How do we Design using Daylight?

•  Simulation shows the behavior of natural light within a space – a visual tool to demonstrate design choices.

•  Ideally used in the design development. •  Use daylight/sun as the first layer of ambient light. •  The building itself = luminaire. •  300lux is becoming the average for daylighting levels in a building but the

modelling can be tailored to custom requirements.

What is daylight modelling?

Designing with the correct light levels and diffusion for a specific building

Typical Daylight Studies

Renders can give client realistic views of the end result

Typical Daylight Studies

•  The building as a whole •  Its global position (site) •  Obstructions (external and internal) •  Surfaces •  Key design features that effect daylighting •  The intended use of the space – how much light needed? •  Size and location of skylights/walls •  How can we positively effect the outcome �

�

Daylight analysis should look at:

•  Radiance – a snapshot in time. A time on a day (noon, sept 21st) Shows exact light levels (within accuracy of solar deviations).

•  Daylight autonomy – yearly average/

sliding scale. Choose hours of operation Lux level – tied to space function What % of time does the space reach the target?

300 lux – 60% of the time during hours of Operation i.e.7 am to 6 pm…. goal is good ambient light as the first layer of light!

Radiance vs Daylight Autonomy

Original design by architect

Let’s work through a simulation

Modelling shows way too much light in the pool area which can result in glare reflection off water

Summer solstice at Noon

Note: Glass is transparent and not translucent which lets direct sunlight through causing extensive glare patches

Revision 1: Change upper 3m of glass wall to Kalwall Translucent Panel

Result: Still too much daylight

Revision 2: Reduce rooflight area

Result: Improved but need to look at glare management

Revision 3: Upper 3m of glass changed to Kalwall for glare reduction

Upper 3m of glass area changed to Kalwall

Upper 3m All glass walls = too much glare creating intense reflectivity on water surface and is a life safety

hazard of glass area changed to Kalwall

Direct sunlight is away from the pool area eliminating glare blinding on the water surface meaning lifeguards are able to see people in the pools at all times

Result achieved with upper 3m of glass changed to Kalwall

3D section views

•  Specific light level requirements can be achieved •  Identifies excessive light or under-illumination •  Used as a submittal item for day lighting credits in

programs such as LEED, Greenstar •  Compare different materials – glass / translucent /

overhangs / light shelves •  Size and spacing of day lighting options – Bigger is not

always better! •  Eliminates potential solar glare and hotspots for smooth

diffused lighting throughout.
