Trimble and Nemetschek push for interoperability As a result of the alliance, workflows between products like Tekla Structures and SCIA Engineer could be streamlined

New HP inkjet ‘60% faster than LED’ P’s new PageWide XL printers, which can print up 30 A1 colour prints per minute, are the first CAD-focused printers to be based on HP’s PageWide Technology, an inkjet technology that prints from a scalable printhead across the entire page in a single pass.

HP reckons the new printers are so fast that they can do the job of two printers in one single device, providing monochrome and colour prints speeds up to 60 percent faster than the fastest monochrome LED printer.

n what appears to be a big win for interoperability in the AEC industry, Trimble has formed a strategic alliance with Nemetschek Group with a view to expanding the deployment of BIM across the entire Design-Build-Operate (DBO) lifecycle of buildings.

The companies intend to transparently share data formats and, much like the Trimble / Bentley Systems alliance of last year, tighten the connection of Virtual Design & Construction (VDC) solutions to real data from the field and real objects in the physical world. Both companies say they are committed to open standards and workflows.

“Across the DBO spectrum, customers want the freedom to choose the best tools for the job and the security of knowing those tools will work together. But too

often they find that the data they need is not interoperable across their different software workflows,” said Bryn Fosburgh, VP, Trimble’s Construction Technology Divisions. “Our companies’ shared vision is to give users a choice, rather than dictate what they use.”

Trimble and Nemetschek plan use the Trimble Connect platform (Trimble’s cloud-based collaboration environment) to integrate design modelling and 5D construction management workflows and create close interoperability between selected Trimble solutions—including SketchUp, Tekla Structures, Vico Office, Trimble Prolog, Trimble Field Link and MEPdesigner for SketchUp—and solutions in the Nemetschek portfolio, such as Allplan, ArchiCAD, DDS, SCIA Engineering, Vectorworks and Nevaris.

Tekla unveils analysis and design tool ekla Structural Designer is a new analysis and design tool for structural engineers who work on commercial building projects. The software is designed to complement the company’s Tekla Structures BIM tool and offers features for optimising concrete and steel design.

Tekla Structural Designer enables structural engineers to create a single analysis and design model. According to Tekla, this eliminates the need for postprocessing analysis results. Fully automated loading and design includes wind loading and finite element analysis while product documentation is automatically produced.

Engineers can create and compare multiple design options to help determine the most competitive scheme and manage changes, say the developers.

Tekla claims changes can be easily managed and applied across the entire model to instantly assess impact and automatically get a re-design in seconds.

T

Calculation reports that automatically update are said to eliminate the need to generate new reports manually when changes occur.

Structural engineers can synchronise models with Tekla Structures and other BIM software using auditing tools that show what has been added, changed or deleted during integration.

Meanwhile, Tekla has also released a new version of its structural and construction-focused BIM tool. Tekla Structures 21 delivers new features for interoperability, drawing control, usability and performance. In addition, a new service — Tekla Model Sharing — allows project team members to work on the same Tekla model from any location.

Advertorial

BIM has helped the construction industry design, build and manage higher performance buildings. Now itÕ s time to take BIM to the next level, by integrating design and decision support tools within BIM solutions.

Our buildings are key to our lives. They provide for our shelter, production, community, culture, education, justice, etc. Many governments recognized that our buildings also consume most of the energy we use, create about half of our greenhouse gas emissions and contribute greatly to health, efficiency and productivity of the population. Higher performing buildings can create sustainable economic advantage.

But buildings are deceptively complex to design, build and operate. Their economics can be equally complex.

Success requires vast teams of experts and specialists many of whom use disparate tools to make their decisions.

The promise of CAD (Computer Aided Design) has always been to design buildings Ô inside the computerÕ , automate calculations, predict material and system behaviours, optimize design decision making, manage construction, usage and maintenance throughout the buildingÕ s life. BIM (Building Information Modelling) as a modern CAD tool has become a key software component enabling buildings to be designed, constructed and managed through their life cycles.

Many countries are driving building industry initiatives to gain economic advantage or, at least, not fall behind.

For example: Whole Building Design (ref: US Institute of Building Science) or BIM level 2 and 3 in the UK or the Dutch governmentÕ s Vabi research institution as the countryÕ s center of expertise on building service calculations.

For over 40 years Vabi¨ has produced Innovative Software to create better and more energy efficient buildings that mprove the lives of owners and tenants.

Vabi¨ is the market leader for building performance software in the Netherlands and serves more than 2,000 clients in the engineering and building owner markets; from international blue-chip organizations to small practices.

The Vabi BIM Apps support our preliminary design in Revit¨ " Sander Flach-Klunder Architecten The Vabi¨ ¥

¥

Privatized in 2010 and now expanding internationally Vabi¨ has created Apps to make their software solutions available worldwide and within Autodesk¨ Revit¨ . The Apps extend BIM to a new higher level by incorporating building performance calculations, providing design decision support, monitoring design iterations and supervising goal achievement within your Revit¨ model.

The Vabi¨ apps plugin to and extend Autodesk¨ Revit¨ to integrate more decision making, monitoring and supervision into your BIM model. This provides goal alignment, decision visibility and supervisory transparency to the whole team during the design process and beyond. They make simulation available to everyone Ð not just to specialists.

The Vabi¨ Apps help everyone, especially architects and MEP engineers, make better design decisions throughout their buildingÕ s lifecycle - from conceptual design though detailed design, financing, construction, maintenance and operation. Results from all the Apps are reported in the Performance Dashboard so you have just one place to check your BIM model against all requirements.

Revit 2016 tuned for speed utodesk has focused a lot of its development efforts for Revit 2016 on user productivity with the new release incorporating a number of new features and settings to boost model performance.

With the new ‘Navigation during Redraw’ feature Autodesk says models can be navigated smoothly and continuously without having to wait for the software to finish drawing elements at each step when panning and zooming around a view.

Model performance in large projects can also be improved by new settings in the calculations drop-down.

According to Autodesk, Revit 2016 also takes better advantage of video hardware to provide faster updates to views that contain multiple instances of families. Improved linked file performance also means Revit models with links display faster, with geometric display calculation working only on links that appear within the crop region.

Interoperability has been enhanced with improved IFC linking, With IFC Links and Rooms when creating rooms in the host model, you can use many IFC-based

New Z+F solution registers point cloud data on the fly

Point cloud processing and meshing

oller + Fröhlich’s new 3D laser scanner, the Z+F IMAGER 5010X, is said to come with a unique navigation system which works both outdoors and indoors. This is made possible by GPS and MEMSbased inertial measurement unit (IMU) sensors, combined with an automatic registration capability, which estimates the scanner position and orientation without any external targets. The scanner will also track the movements while carrying the device on to the next scanning position.

Things appear to get even more interesting when combining the Z+F IMAGER 5010X with the new Z+F LaserControl Scout Windows tablet software. This resulting so-called ‘Blue Workflow’ allows users to check data and target quality and register scans before leaving the site. If any gaps are found in the data users can then fill them in with more scans, helping ensure the point cloud dataset is complete.

As data registration and verification is traditionally done back in the office this could be a huge time saver by reducing

hinkbox Software used last month’s SPAR International conference in Houston, Texas to preview Sequoia, its AECfocused software that converts point cloud data into geometry.

the need for site re-visits.

Z+F LaserControl Scout software automatically synchronizes all scan data locally and, after registration, updates all scans on the scanner.

Data transfer between the LaserControl Scout software and IMAGER 5010X is carried out over high-speed WiFi (802.11n with dual antennas), which can move 200MB of data in 30 seconds.

Both devices can be used in parallel, which helps minimise time on site: the Scout software can register scans while the laser scanner captures new data.

New point cloud tools target Revit users he annual SPAR conference was the launchpad for two new point cloud / laser scanning tools for Revit: PointSense for Revit and EdgeWise 5.0.

PointSense for Revit is a brand new laser scanning software from FARO, designed to evaluate and convert point cloud data into BIM models inside Revit.

The software provides tools for ‘fast and precise’ creation of walls, including automatic generation of different wall types and thicknesses.

Faro says tools for fully automatic wall alignment create continuous wall ranges and orthogonal floor

plans, even on varying floor levels. Wall angle tolerances can be defined by the user.

Additional functions include automatic generation of family types based on dimensions extracted from the point cloud and the creation of digital ground models (so called Toposurface).

PointSense for Revit also provides a range of 3D design utilities. The application allows for the creation of 3D model lines and construction points via an all new 3D point snap within the point cloud.

EdgeWise 5.0 from ClearEdge 3D is the latest release of a product that

Ultra portable 15-inch mobile workstations CAD folks with hefty laptops have long envied the Ultrabooks and MacBooks of fellow travellers. But a new generation of slimline mobile workstations is changing the way you can do CAD and BIM on the go, writes Greg Corke.

T

he first mobile workstations were 5kg beasts, almost guaranteed to put your back out on work trips.

Weights have now come down, but most 15-inch machines still come in at a hefty 3kg. Bruised shoulders from laptop bags are no longer guaranteed, but you will likely feel the strain at the end of the day.

Until recently, attempts at ultra mobile workstations have meant serious tradeoffs in both performance and screen size.

When your job relies on detailed architectural or engineering design, running CAD or BIM software on a 14-inch laptop simply will not cut it for some.

Everything changed in 2013 when Dell unveiled the Precision M3800, the first proper ultra portable mobile workstation with a 15.6-inch screen.

At 1.88kg in weight and 8mm at its most slender, this MacBook Pro look-alike certainly turned some heads.

Since then HP, Lenovo and MSI have all followed suit, delivering 15-inch machines that are certified and optimised to run 3D CAD and BIM software but also offer the same mobility as a slimline business laptop.

Compared to a standard 15-inch mobile workstation, there are some compromises.

On the whole, performance is lower.

There is a maximum 16GB of RAM (instead of 32GB), which could be a stumbling block for those with complex Revit models. There is only room for one or two drives (instead or two or three) and you can forget about having a DVD drive.

But they are considerably lighter. Most come in under 2kg and when power adapters are included the savings can be as much as 1.5kg.

There is no standard template for these next generation mobile workstations.

HP Zbook 15u This new addition to the HP ZBook family goes all out for portability but still retains the key enterprise features of its older siblings Portability is clearly a big focus for HP at the moment, launching not one but two slimline 15-inch mobile workstations in the space of six months.

The HP ZBook 15u is the more enterprise-focused of the two (the HP OMEN Pro (p22) being the other) and delivers many of the features you would expect to see in a higher-end mobile workstation.

This includes fingerprint scanner, Smart Card reader, (side) docking port and the impressive HP Easy Access Door (more on this later).

The big pitch for the ZBook 15u is its portability and HP is focusing much of its marketing efforts around the machine’s ‘Ultrabook’ standing. For those not familiar with this Intel classification, for a laptop to be called an Ultrabook manufacturers have to meet certain specifications relating to battery life, thickness, performance, wake from sleep time and others.

With the HP ZBook 15u (and Lenovo ThinkPad W550s) things get a little confusing as not all models qualify as an Ultrabook — specifically, we think, those that do not use an SSD for the OS — but on the whole one can expect all models to come close.

Key to the ZBook 15u achieving its Ultrabook status is the Intel Core i7-5600U, an Ultra low voltage (ULV) dual-core CPU based on the Broadwell architecture.

This CPU might lack the multi-threaded power of the quad core chip found in the HP OMEN Pro and Dell Precision M3800, but with a clock speed of 2.6GHz rising to 3.2GHz, it still delivers where it matters for CAD and BIM. And it does so without breaking into a sweat. Fan noise was kept to an absolute minimum, even www.AECmag.com

p12_13_15_17_18_21_22_25_Mobile workstations.indd 15

under heavy loading.

Like most mobile workstations, the HP ZBook 15u relies on switchable graphics with a view to saving power. It uses the built in Intel HD Graphics 5500 for mainstream apps and swaps over to the higher performance CAD-focused AMD FirePro M4170 (1GB GDDR5) as and when required.

This should happen automatically, as it did for our CAD test suite, but individual apps can be matched to GPUs in AMD’s Catalyst Control Center software.

Despite its entry-level positioning, the AMD FirePro M4170 delivered some decent scores in our 3D tests.

Compared to the more powerful Dell Precision M3800 with Nvidia Quadro K1100M, it was only 19% slower in Creo and 27% slower in SolidWorks. In practice it should give users a good experience when working with small to mediumsized CAD and BIM models.

While compromises have been made with CPU and GPU, there is nothing entry-level about the storage with a PCIebased 256GB HP Z Turbo Drive for operating system and applications and a 512GB SATA-based SanDisk X210 2.5inch SSD for data.

Our tests showed that the HP Z Turbo Drive delivered around 70% better sequential read speeds and 40% faster sequential read speeds than the SanDisk X210, which is great news if you frequently copy large files. 3ds Max also opened slightly quicker, taking 17.3 secs on the HP Z Turbo Drive and 18.4 secs on the SanDisk X210.

However, in the AS SSD benchmark, the SanDisk X210 SSD actually scored higher in random read/write performance and access time so the benefits of PCIe storage are not as broad as one might presume.

As you would expect from an HP ZBook, build quality is excellent and despite its 1.91kg weight the machine feels solid and well built.

Serviceability is superb with all key components easily accessible behind the

excellent HP Easy Access Door. Simply remove the optional security screw, slide the switch, pull off the panel and memory, storage, WLAN and battery are all within easy reach. HP scores big points here, standing head and shoulders above the competition, which all require messing about with lots of fiddly screws.

Despite its moderate spec, the HP Long Life 3-cell, 50 WHr Li-ion battery lasted a respectable two hours 40mins under the heavy load PCMark 8 battery test.

The multi-touch image sensor Touchpad is precise and the backlit keyboard comfortable in use but a numeric keypad is noticeably absent. Dedicated power, airplane mode and mute buttons sit conveniently between keyboard and screen.

The HD (1,920 x 1,080) matte screen is of good quality but, in this age of IPS panels, nothing outstanding. There is no optional touch screen like there is with its ‘Ultrabook’ sibling, the ZBook 14.

Even with a thickness of 21.42mm HP has managed to include a standard RJ45 port in the chassis. This ingenious design has a spring-loaded hinge that expands the port to its full width when you plug in an Ethernet cable. Dual Band Wireless-AC is on tap for high-speed WiFi. There are four USB 3.0 ports, one of which is always on so smart phones and other devices can be charged even when the mobile workstation is off. DisplayPort and VGA give both digital and analogue options for connecting to external displays.

The HP ZBook 15u is an impressive addition to the HP ZBook family, giving fans of the enterprise-class CAD laptops an ultra-portable 15-inch offering.

While the ZBook 15 and ZBook 17 are pitched as desktop replacements, the ZBook 15u, with its entry-level 3D graphics feels more like a companion to a desktop machine.

But if you are after a slimline, highly portable ‘Ultrabook’ for travel that is also optimised for entry-level 3D CAD and BIM, it is an excellent choice.

However, the way that Lenovo Intelligent Cooling is one has implemented its batteries is rather of a number of features unique.

With only 2 CPU cores, performance will be restricted in ray trace rendering software. However, with a clock speed of 2.60GHz (Turbo up to 3.20GHz) it is a decent option for single threaded CAD and BIM operations.

For 3D graphics, Lenovo has taken a different tack to HP, partnering the Intel CPU with an entry-level Nvidia Quadro K620 GPU. In our hands-on 3D CAD tests the machine felt responsive, even with some relatively complex models. However, it is hard to put an exact figure on performance as a) our SolidWorks benchmark does not run on Windows 8.1 and b) the benchmark scores in Creo were a little erratic — ranging from. 3.44 to 4.12.

This inconsistency could be down to our test machine being a pre-production unit.

We did experience a few quirks with the system, specifically in relation to Lenovo’s ‘Intelligent Cooling’ technology, which seemed intent on clocking the CPU right down to 1.2GHz under most loads, significantly impacting performance.

Switching off Intelligent Cooling meant performance was restored to expected levels — and it did this without negatively impacting fan noise. Lenovo told AEC Magazine that it is working on a patch to fix this issue.

Dell Precision M3800 Recently updated with a new 4K screen and Thunderbolt 2, Dell’s slimline beauty continues to shine, albeit with a few tradeoffs.

First unveiled in Autumn 2013, the Dell Precision M3800 was the original ultra portable 15-inch mobile workstation and, in our opinion, still the best looking. This slender MacBook Pro look-alike may lack originality but it is still a thing of beauty.

Beyond aesthetics, there is an innovative use of premium materials. A CNC machined aluminium lid protects the glorious 4K touch display, while a magnesium mid panel, overmoulded with silicone does a great job of keeping the palm rest surface cool to touch. The carbon fibre base gives lightweight strength as well as keeping laps at a comfortable temperature.

The insulation is important as the machine does produce a fair amount of heat, evident by its two audible fans, which kick into action during most CPU and GPU intensive operations. Warm air is expelled at the rear underside of the machine.

What the Precision M3800 lacks in acoustics, it makes up for in performance.

With four CPU cores, the 37W Intel Core i7 4712HQ CPU cut through our 3ds Max rendering benchmark in a mere 300 seconds, twice as fast as the UltraBook-class HP ZBook 15u and Lenovo ThinkPad W550s, and not far behind the HP OMEN Pro or even the desktop Lenovo ThinkStation P500 reviewed earlier this year.

With a clock speed of 2.30GHz going up to 3.30GHz, a small improvement over the Intel Core i7 4702HQ CPU in last year’s model, it also performs well in single threaded applications.

For a machine of this size, 3D graphics performance is impressive and the 2GB Nvidia Quadro K1100M delivered solid scores in our CAD benchmarks. But there is

www.AECmag.com

p12_13_15_17_18_21_22_25_Mobile workstations.indd 21

a BIG caveat to this — and that is the impact of display resolution on 3D performance.

The new 4K (3,840 x 2,160) Dell UltraSharp touch panel is a thing of beauty. Vibrant colours certainly make the most of its pin sharp resolution and it is arguably the best laptop panel we have seen at AEC Magazine (even with its glossy finish that can be prone to annoying reflections in direct light).

But with four times as many pixels to push about on screen 3D performance can slow down. Running our SolidWorks benchmark at 4K (3,840 x 2,160) resulted in a significant drop in performance, less than half that we experienced at HD (1,920 x 1,080).

With PTC Creo the impact of resolution was negligible, so it is important to note that performance in relation to resolution will likely depend on the application, datasets and how the model is viewed (e.g. realistic effects or shaded).

The good news is, because HD uses exactly half the horizontal and vertical pixels as 4K, the image still looks good at 1,920 x 1,080 resolution. With other panels when you use a non-optimal resolution fonts and images will be blurry.

This is also an important consideration as software developers make changes to user interfaces. Many applications are still not optimised for 4K so icons and dialogues appear unreadable even with Windows settings ramped up. Having a real choice of HD or 4K in the Precison M3800 will help smooth the transition.

An HDMi and Mini DisplayPort are included to connect to external displays.

Storage is more standard, courtesy of a 256GB Solid State Drive Mini-Card (mSATA). While some may find this a little light on capacity, there are plenty of ways to remedy this — either by upgrading to a 512GB or (soon) 1TB mSATA, or adding a 2.5-inch drive (HDD up to 1TB, SSD up to 512GB or Solid State Hybrid

Hard Drive (SSHD) up to 512GB).

User upgrades are possible but you will need a T5 Torx screwdriver to remove the 12 screws that secure the back panel. In addition to storage and memory, you will also find the 6-Cell battery which is rated at 91 WHr and not bad considering the spec of the machine. It lasted 2h 11min in our heavy duty PCMark battery test but we would expect much longer operation when using standard office applications.

The backlit island style keyboard and spacious trackpad with soft touch surround are a pleasure to use, but there is no numeric keypad.

For connectivity, the laptop is well appointed with three USB 3.0 ports and Thunderbolt 2 — a nice addition for those that want lightning fast external storage.

Intel Dual Band Wireless-AC 7260 means CAD data can be transferred over WiFi more quickly than with 802.11 a/b/ g/n (providing you have an optimised network, of course). Gigabit Ethernet is still the preferred way to connect to the network but the slimline design means no Ethernet port.

A USB to Ethernet adapter is included in the box though.

Other notable omissions include fingerprint scanner, smart card reader or dedicated docking port — all important enterprise features — although the machine can connect to a USB dock.

Finding the balance between performance and portability is a major challenge for mobile workstation manufacturers. The emphasis on delivering performance in an exceedingly sleek chassis means inevitable trade offs in battery life and fan noise but the Precision M3800 continues to be an exceptional machine for CAD on the go, though be sure to consider the implications of having a 4K screen.

Both have a Quadro K1100M (2GB) GPU and 16GB of RAM. In terms of spec, storage is the big differentiator with the HP OMEN Pro having fast PCIe-based storage in the form of a 512GB HP Z Turbo Drive while the Dell has an mSATA SSD and, crucially, space for a 2.5-inch drive (SSD or HDD), which can be very useful if you want to store a lot of CAD data.

While the HP Z Turbo excels in sequential read/write tasks — i.e. copying large files or in workflows where exceedingly large files are the norm (e.g. video editing, point cloud processing and simulation) — mainstream CAD users probably will not notice much benefit. (See our PCIe vs SATA SSD article for more on this — tinyurl.com/PCIe-SATA-SSD-AEC).

It looks exceptionally smart but is prone to fingerprints.

Group test continued from page 22.... found we had to turn the machine round a full 180 degrees.

At the rear you will find four USB 3.0 ports (all charging), mini DisplayPort and HDMi. With such a slimline chassis, there is no Ethernet port but a USB to Ethernet adapter comes in the box.

Performance is excellent. Having a full 0.2GHz over the M3800 (0.4GHz in Turbo) it has a clear lead in our multi-threaded, CPU intensive 3ds Max benchmark and is only a whisker behind the MSI WS60.

With the same Quadro K1100M GPU as

the M3800 the performance increase is far less pronounced in our Creo and SolidWorks graphics tests.

Fans kicked in significantly under load, making a fair bit of noise. They also ran slowly in the background when idle but this was less noticeable than with the MSI WS60.

We actually experienced a few issues in our SolidWorks test with PhotoView 360 crashing regularly. It should be emphasised again that this was a pre-production unit and software issues like these are likely to be ironed out with the shipping

machine and during CAD certification.

Performance could also change slightly.

Overall, the OMEN Pro is an excellent addition to HP’s workstation portfolio — a beautifully styled, slimline laptop that delivers performance to rival most standard 15-inch mobile workstations.

There are some compromises, of course.

Battery life is not great and some may find the storage too limiting and rear ports annoying but, apart from these minor gripes, the OMEN looks to be a very impressive machine for mobile CAD/BIM and entry-level design visualisation.

External storage for mobile workstations Mainstream 15-inch mobile workstations can typically hold up to three internal drives but their slimline siblings are limited to one or two. This increases the importance of external storage for storing huge CAD datasets.

When you are talking about Gigabytes of data performance is important. No one likes waiting, particularly when rushing out of the door and late for an appointment.

Mechanical Hard Disk Drives (HDDs) with spinning disks used to be the only serious technology for storing CAD data but with capacities increasing and prices dropping Solid State Drive (SSD) technology is now becoming an attractive alternative — not only because of the superior performance but built-in protection against accidental drops.

Most drives are USB 3.0 but with Thunderbolt 2 now being introduced in some machines (e.g. Dell Precision M3800) this could change over time.

We tested four different portable storage options, all of which can be powered by the USB or Thunderbolt bus.

Our initial testing was simple: the time taken to transfer 7GB (13,500 files) of CAD data to and from the drive.

We then did a parallel copy test where we transferred three sets of data in quick succession so all three were being copied at the same time. If, like me, you often grab datasets from different folders as and when you find them, this can be a real bottleneck with mechanical drives.

Akitio Palm Raid (512GB) 1 £436 (scan.co.uk) 1 year warranty This high-speed Thunderbolt drive features two mSATA SSDs combined in software RAID 0 (where two drives become one to boost performance). For those that prefer to protect against data loss, it can also be formatted in RAID 1 (mirrored) so your data should stay safe even if one drive fails.

The drive is primarily designed for Mac OSX so needs reformatting for Windows. This proved to be easier said than done as some partitions were locked (needed both DISKPART and Disk Management tools).

Once up and running it was the fastest drive on test, taking just 40 seconds to read the CAD dataset and 36 secs to write. However, rather surprisingly, it slowed down in our parallel test completing it in 137 secs (read) and 133 secs (write).

With a high-quality aluminium case, built in cable, carry case and high-speed transfer, the premium grade pocket size drive is no doubt an attractive package.

However, at over £1 per GB the price is high and despite it winning our standard copy test by some margin, with performance dropping under parallel copy you need to carefully consider the way you work to choose it over the Samsung T1.

Samsung’s USB 3.0 T1 SSD fits easily within a pocket.

The performance of the drive is also excellent, taking 48 secs to read and 55 secs to write our CAD dataset.

It also performed exceedingly well in our parallel test completing the copy in 100 secs (read and write), quicker than it would have taken to copy all three in sequence.

Overall, it is a hugely impressive drive and comes highly recommended. At £0.36 per GB it is significantly more expensive than a mechanical drive, but for the performance it offers in a compact footprint it cannot be beaten.

The Samsung T1 SSD is also available in 250GB and 1TB capacities.

SSD 850 EVO M.2 (500GB) 3 £144 (scan.co.uk) 3 year warranty + Startech M.2 Enclosure £17 (uk.insight.com)

This DIY solution houses a SATA-based Samsung M.2 (2280) SSD in a metal Startech caddy. Installation takes a few minutes and, hey presto, you have a highly portable SSD, not much bigger than a USB stick.

Performance is slightly below that of the Samsung T1 (sequential — 51 secs read, 58 secs write) (parallel — 118 secs read, 120 secs write).

At £161 it is the cheapest of all the SSDs and offers flexibility, should you wish to install the M.2 (2280) SSD in a laptop or desktop, but other than that we would find it hard to recommend over the Samsung T1 SSD. Seagate Backup Plus Slim 4 (2TB) £62.50 (amazon.co.uk) 2 year warranty This slimline traditional mechanical drive is only 12mm thick. It is housed in a solid metal case which comes in blue red, silver or black.

1

For sequential read and write, performance is pretty good. Read speeds, in particular were only 1.5 times slower than the Samsung T1 SSD, completing in 72 secs (124 secs write).

The limitations of mechanical drive technology were exposed in our multiple copy test, as the drive slowed right down when transferring three separate datasets in parallel (525 secs).

This is likely to slow down as data gets scattered over different parts of the disk (as the drive head has to move further). However, a managed approach to file copy (dataset by dataset, rather than throwing everything at it at once) will help ease this bottleneck.

At 1.6 pence per GB, the Seagate Backup Plus Slim wins hands down on cost.

And it also cannot be beaten on capacity — 2TB makes it incredibly attractive to those with swelling datasets.

ArchiCAD 19: performance BIM With significant speed increases in this bumper update to ArchiCAD, Graphisoft is clearly aiming to get the attention of Autodesk Revit customers who are frustrated with slow model performance.

clues as to what you will be doing next, As you work in one tab making edits and updating the design, the software will dynamically allocate the update of the model in those tabbed views to spare cores or processing capacity. The net result is that moving from tab to tab, users will find the model ‘instantly’ updated or a long way into performing a task — such as a 3D section. So the software appears significantly more responsive and makes the most of today’s multi-core architectures.

Graphisoft explained that in addition to the ‘tabbed clues’ for predictive processing, the new predictive algorithm will do some analysis as to workflow and commonly used tools, to further refine the allocation of processing. To ensure that all this additional ‘front-loaded’ processing doesn’t impact the overall speed of ArchiCAD, the software leaves one core free. By using this unused computer capacity, even if the software anticipates incorrectly, nothing has been lost. www.AECmag.com

Tabbed workspaces make it much easier to flip between sections, model view, drawing view, render or elevations

As to how much quicker this makes ArchiCAD 19 over 18? Graphisoft stated the benefit can be from ‘Instant’ to a 70% improvement in creating 3D views. The opening time for all model-based sections, elevation or 3D documents has dropped by half. Beta testers have told me that it’s a significant improvement and absolutely screams on Apple’s new Mac Pro, which comes with an Intel Xeon processor with up to 12 cores.

OpenGL It’s not just editing and rendering that have seen speed improvements in this release; graphics performance has also been further optimised with faster and smoother OpenGL navigation. It is now possible to navigate through extremely large models with a ‘flickerless display’, reaching frame rates well in excess of 30 frames per second. In reality, this kind of performance is games software territory and brings realtime performance to BIM. www.AECmag.com

In the resulting PDF document, you can show or hide content by layers, or navigate among layers.

Teamwork and BIM Server have also seen some useful updates, such as a BIM Cloud / BIM Server diagnostic tool.

BIM X: The company’s unique portable model sharing format has been slightly enhanced, where authors can control which element information will be published as part of the Hyper model.

MEP: Collision detection now works for all elements classified as MEP-type in Element Settings and not just for MEP Modeler elements. As a result, collision detection works on all imported IFC MEP elements (regardless of which MEP application exported the IFC model), and all ArchiCAD project MEP Objects.

BIMCloud Designer: Launched last year, BIM Cloud is Graphisoft’s cloud extension for ArchiCAD teams. It can create private microsites or public clouds for teams to collaborate on BIM projects.

While mainly beneficial to large firms, it seems that small practices wanted to get some of the benefits and so have delivered a low-cost version to enhance distribution but it is missing the teamwork capabilities.

Nemetschek The final thing to note is a small corporate change, but Graphisoft also unveiled its new logo, which is actually very similar to the old one but now includes the brand ‘Nemetschek’ within it. Graphisoft is owned by Nemetschek, a German developer, which started out with Allplan — a BIM 28

May / June 2015

p26_27_28_30_AECMAYJUNE15_ARCHICAD.indd 28

system popular in Germany.

Nemetschek also owns Vectorworks (Formerly Minicad), Maxon (rendering) and Bluebeam (PDF workflow) amongst other firms. Historically the company has tended to ‘silo’ its acquisitions but now there appears to be a more cohesive approach to push the brand.

Conclusion This is another great release of ArchiCAD with loads of crowd pleasers. Putting performance aside, changes to the interface, giving maximum model room, really makes a big difference and certainly helps make the most of a laptop screen.

There are a range of useful new features and capabilities ranging from small productivity enhancements to collision detection and IFC output.

Following Bentley and Autodesk, point cloud support is now the de facto standard in the industry, as more firms experiment with importing survey data to rapidly generate BIM models from real-world measurements. This is definitely a useful future technology.

The decision to work with Rhino and Grasshopper is also a no-brainer for getting complex forms into ArchiCAD. It saves the company developing computational design tools, as Bentley (GC) and Autodesk (Dynamo) already have done and Rhino is also exceptionally popular in practice.

Despite being the most mature BIM application on the planet, you have to admire Graphisoft’s commitment to driving performance and fundamentally re-architecting ArchiCAD to utilize the capabilities of multiple cores on both Windows and Apple OSX. BIM models are big and complex and as models get ever bigger and more detailed it’s important to use whatever hardware is available to accelerate this.

When looking forward and knowing that processors will get more cores but single core performance won’t increase at the same rate, software has to be ready for this.

Autodesk Revit, which only runs in Windows, has some multi-core support, but these aren’t for discreet processes and apply to separate capabilities like rendering. A number of functions are multi-threaded (Save / Load etc.) but the software’s architecwww.AECmag.com

ture is just not designed to work that way, which is a concern, considering the way the next generation processors will work.

In a BIM discussion with an Intel employee we were told, “As processor clock speeds dip, you will see the number of cores greatly increase. We could have six or 12 cores minimum in the future. If you think of these like lanes of a motorway, software that just uses one core will be deciding to only use the inside lane, with all the other ‘traffic’ in your system.

Software that needs to provide performance will have to make use of all the other lanes, as opposed to Revit stubbornly staying in the slow lane”. We wonder if Autodesk has any plans for a major reworking of the Revit code or, which seems more likely, it may bypass updating the software architecture of the desktop version of Revit and can get better model performance by leveraging a new system architecture in ‘the cloud’?

With 19, Graphisoft is certainly seeking to have ArchiCAD’s performance on big models compared to Revit’s. At the launch event Graphisoft’s ArchiCAD/Revit comparisons were very much at the forefront.

Graphisoft showed its own benchmark results finding the insignificant’ improvement from Revit’s current multi-threaded capabilities and went on to state that ‘16GB is the minimum RAM requirement for Revit, while 16GB is the maximum you will need in ArchiCAD’.

Graphisoft’s development team feels it does a better job with 3D graphics accelera-

tion, multi core utilisation, memory efficiency and now predictive processing.

For Mac users, ArchiCAD is a much more simple choice as there’s only two BIM modellers on the market that run on OS X ArchiCAD and Vectorworks. But ArchiCAD 19 is the only multi core BIM tool that could justify the purchase of a lovely Mac Pro and make use of the cores on its Xeon processor.

From multi-threading to multi core Multi-threading is a program’s ability to break itself down to multiple concurrent threads that can be executed separately by a computer.

A multiprocessor (or multi-core) computer can run two or more of the threads at a time, which means that the program “runs faster” on a multiprocessor machine than on a single-processor machine.

“Traditional” single-thread

30

applications cannot make use of two or more processors, therefore they don’t run faster on multiprocessor machines.

Multi core processors. All Modern Intel desktop processors have multiple cores.

Depending on the product there can be 2, 4, 6, 12, even 18 cores per processor.

In a dual processor system, which has 4 cores per pro-

May / June 2015

p26_27_28_30_AECMAYJUNE15_ARCHICAD.indd 30

cessor, there would actually be 8 physical cores available.

In an ideal world, four cores would provide linear scaling of four times the processing capacity of one but most applications don’t see this kind of benefit.

Hyper-threading is a very specific technology from Intel, which aims to improve the parallelisation of tasks for software developers. Some

applications use Hyperthreading, many do not.

Hyper-threading turns each physical core into a virtual dual core system. So a dual core processor that supports Hyper-threading actually has four virtual cores.

In our example of a dual processor system, each with four cores (eight in total), the Operating System would actually see 16 virtual cores.

Hyper-threading is slower

than actually having completely separate physical cores, as there are some operations which cause ‘collisions’ of system resources, which can negate the performance advantages and actually make it slower.

Software has to be written to get the balance right.

When done well, speed benefits of around 15% can be achieved vs no Hyperthreading.

Comment

Transitioning to BIM pt2 About the author Shaun Bryant is an Autodesk Certified Professional with twenty-six years total industry experience using AutoCAD and Revit.

Introduction This is the second in a series of three articles about making the move to BIM (the first part appeared in the March / April 2015 edition of AEC Magazine).

Using the scenario from part one of the series A medium sized, multi-disciplinary CAD practice, involved in architecture, structure and services, which often works with external contractors. Based in London, UK, it has fifteen core users, with anywhere up to twenty-five users when contract CAD personnel are brought in to make up capacity. A CAD manager is in place who acts as liaison between management at director level and the users in the CAD team. The team is currently using Autodesk AutoCAD for all of its work and is up to date with the latest version, due to an active Autodesk subscription agreement.

The practice has decided to use Autodesk Revit as its BIM tool of choice. There is a need to manage both the implementation and training required to make the practice both effective and efficient.

The article is written from the CAD manager’s perspective.

Sean Bryant gives more practical advice on how a CAD manager in a medium-sized, multi-disciplinary practice can help smooth the path to collaborative Level 2 BIM.

Addressing the Revit implementation

Training Needs Analysis (TNA)

CAD manager to director level “Revit is now our tool of choice. We need to invest in our IT and server capacity to ensure we have the server space to handle our Revit central models, and make sure that our users have enough local space to work with local worksharing models.”

CAD manager to director level “We will need to ensure that all Revit users undergo a Training Needs Analysis (TNA) to assess their training needs and requirements. This will give us a picture of exactly what they need and allow us to use the training effectively and get the most out of our incumbent training provider. It is imperative we allow the team to work with their strengths but also get trained up on areas of weakness, so that we have fully rounded Revit users that are effective and productive.”

CAD manager to the CAD team “As we move forward with Revit in the practice, we will be working with much more capacity, both locally and on the servers. However, this does not allow us to be lazy. We will have to implement new strategies that allow us to be economical with this new space provided, as we will be working with much larger file sizes than we were with AutoCAD.” Revit project files (RVT files) are bigger files. The CAD manager is making sure that the CAD team is aware that new working practices will be needed to manage this on a day to day basis, and that at director level, they are fully aware that investment is needed in the IT infrastructure. On an operational level, this has to be managed to ensure effective use of the IT infrastructure, to maintain Revit productivity. The last thing the CAD manager wants is a heavy Revit server that slows down local models and hinders the CAD team’s productivity on live projects.

From an IT standpoint also, the IT department managing the servers do not want slow servers overloaded with repetitive Revit data, hence the new working practices must include suitable housekeeping policies that keep the servers quick and lean, so as to handle the Revit 3D models.

CAD manager to the CAD team “We need you all to undergo a Training Needs Analysis (TNA). This is to assess your existing Revit knowledge (if you have any) and what areas you need to work on to make sure you are fully trained on every aspect of Revit you need to perform your role within the practice effectively. We need you to make sure that you include everything in your TNA so that we can get the best training for you from our training provider.”

Effective training on any CAD product is imperative. The CAD manager is using the TNA to ensure each Revit user is trained to their strengths and that any areas where their product knowledge is weak is thoroughly assessed and appropriate training given. The TNA is done individually per user to make sure that each user gets training tailored to them. It also provides the user with the reassurance that with the new CAD product, in this case Revit, they will be fully trained and prepared to use the product on live projects that the practice is, or will be, working on.

Training delivery CAD manager to director level “We will be using our incumbent training provider to provide all of our Revit training based around the findings of the TNA exercise. We will be making sure that all training is scheduled around projects and staffing levels for those projects. We have to make sure that key project staff are trained sequentially, and to allow for at least one key member of project staff to be in the office at any given time when the other project team members are being trained.”

CAD manager to the CAD team “You will be receiving individualised training based on the findings of your completed TNA. We need each of the project teams to build a training roster that allows for one key project team member to be in the office at any given time. We have to make sure that our existing projects are covered at all times. This will be even more important once Revit and BIM are implemented, as we will need to make sure that our central Revit models are fully co-ordinated with external contractors, partners, engineers and the client.”

The CAD manager has a responsibility to manage all of the ongoing projects in the practice. Training will disrupt the smooth running of those projects unless it is managed properly. The TNA process gives exact results on what training is required per user, so the CAD manager can ask the project teams to build a training roster per team, ensuring project coverage, and making sure there is at least one project team member in the office when training is ongoing.

As CAD manager, this management is extremely important to the efficient running of the current projects. There is also a responsibility on the CAD manager to make sure that each team is trained in turn, rather than one member at a time.

You want each team to be fully trained up, so that they can hit the ground running.

But there will always be one key project member remaining (the one that stays in the office when the others are being trained). The solution here is to train that key member when another team is being trained. For example, Key Project Team A Member gets trained with Key Project Team B and vice versa. That way, full project coverage is maintained but all teams get trained with sensible timescales.

Further training and certification CAD manager to director level “Once the CAD team is bedded in and trained on Revit, we need to think about intermediate and advanced training and build a budget and a schedule for this. It is imperative we keep the CAD team lean, trained and efficient on the latest versions and methodologies. The only way to do this is regular scheduled training. We also need to benchmark their Revit knowledge by way of Autodesk Revit Certification. All of our Revit users should become Autodesk Revit Certified Professionals.”

CAD manager to the CAD team “Now that we have Revit set up in the practice and training is ongoing, we need to think ahead towards intermediate and advanced training. We would like you to keep notes of all aspects of Revit that you feel you will need to perform your role within the practice. You will also be offered the opportunity to gain Autodesk Revit Certified Professional status through our training provider.

In order to obtain this qualification, you will need to get approximately four hundred hours of active Revit usage under your belts. Keep a note of your hours and when you hit the four hundred mark, please inform us. We can then get you an examination place for certification.”

Here, the CAD manager is, in essence, future-proofing the practice’s investment both in Revit and the staff. In order to get a return on that investment, the CAD manager is already looking forward to future training for the CAD team. Staying on top of a CAD product once it is in place is imperative, to stay lean, and make sure the staff are fully aware of new version upgrades and methodologies that come with it. With Revit, though, a new version updates all of the Revit data to that particular version, and there is no backward compatibility. All of the project team, including external contractors, partners and the client would need to upgrade as well. Everyone involved with that particular project has to be on the same version of Revit.

Conclusion In this second installment about transitioning to BIM, we have looked at the implementation of Revit and training of the practice staff to use Revit. The physical implementation of the Revit software is fairly simplistic and Autodesk provides full documentation on how to do this. What is paramount here is the server infrastructure, and how it is set up to the advantage of the CAD team using Revit.

Quite often a new server is set up from scratch to allow for the worksharing of Revit projects, along with a professional cloud storage account for use with external parties and for archiving. This would be individual to each and every organisation that uses Revit, but it must be set up to ensure that Revit is used to its full advantage by way of central and local Revit models.

Training is also imperative. For any organisation to get full return on investment on any software that is purchased or subscribed to, the staff must be trained. The training should be mandatory for all appropriate staff, along with (possibly, in this case) Autodesk Certified Professional status.

The Certification qualification then provides a staff benchmark to competency levels, plus it will also highlight any further areas of training required.

Overall, a transition to a BIM application such as Autodesk Revit should not be undertaken lightly. It requires organisation, planning and a will to move forward and utilise the tools Revit provides. With BIM 2 compliance on the horizon for January 1, 2016 in the UK, it is in every organisation’s best interests to make the move to BIM and its associated CAD applications as soon as possible.

Vabi Dashboard A new range of low-cost, add-on design analysis applications aim to provide architects and engineers with a very graphical dashboard for performance feedback early on in the design process.

I

t has proven exceptionally hard to sell building analysis to architects. The vast majority still believe it is a specialism outside of core architectural design. This has not been from a lack of trying. IES gives away some low-level functionality to SketchUp and Revit customers, and Autodesk provides some access via its Suites and Subscriptions, but without widespread success.

One reason for a lack of take-up is that building analysis tools have nearly always failed to integrate well with design tools.

Results are given in measurements that only a building services engineer can understand and even progressive Building Information Modelling (BIM) architects do not prioritise a performance-based process.

The Vabi BIM Building Performance Dashboard provides performance feedback for a wide range of criteria

feedback on design performance over a wide range of criteria.

Over time, Vabi plans to develop scores of these applications, over a range of topic areas which can be ‘pick and mixed’ and displayed in the dashboard. It is not just a range of new applications, it is a whole ecosystem.

Dashboard The most instantly obvious benefit of the new Vabi applications is the dashboard display, which is in the Revit ribbon menu and gives ‘at a glance’ design performance information. Each application has a ‘fuel’ type indicator providing feedback on how well a design matches the criteria specified.

I have seen many demonstrations from Autodesk showing what they think BIM will look like in the future, providing feedback, using on-screen dashboard feedback, for example, but this is the first time anyone has delivered such a system within Revit. It is really simple to understand and does not need explaining.

Market changes The whole design tool market is changing quite rapidly and not just the move from 2D drawing to BIM. Industry silos are coming down, with more firms opting to become multi-disciplinary and benefit from the rich data that BIM provides.

Review ery and subscription. Vabi has looked ahead and designed a development, deployment and subscription payment system that works with the current desktop environment and anticipates the future changes coming to the market, such as fewer dealers, more cloud-based delivery and micro payments.

By keeping the pricing low and enabling short term per-month use, Vabi hopes to attract many Revit users to dip in and out of its software suite and use them on demand, perhaps keeping long term subscriptions to the most regularly used applications.

Modules There are currently 10 modules available in five core topic areas: Financial, Comfort, Functional, Green Building and Secure & Safe. Each application is initially available on a 15 to 30-day free trial followed by a monthly price of $10 to $30 —the difference in price indicating the perceived benefit or complexity of analysis. Apps can be used on a monthly on / off basis and are available in 135 countries.

The initial ten applications available are: Financial: Financial Energy Assessor.

Simulator

and

Financial Simulator For all those ‘what if ’ moments, Financial Simulator pulls together and displays financial performance related data and reveals the P&L, Balance Sheet, Discounted Cash Flow and Return on Investment (ROI) impact of design decisions.

It enables the consideration of design alternatives using comparisons of alternate design options from impact on overall building value, to profitability and is a useful discussion tool with owners and asset managers.

Thermal Comfort Optimizer The Thermal Comfort Optimizer allows the user to set optimal design temperatures for each room in the BIM model. This can increase understanding of energy usage and occupancy requirements.

The software takes into account occupant satisfaction, metabolism, expected clothing insulation level, relative humidity, air velocity, and room heating/cooling setpoints for indoor temperatures in winter and summer.

Lighting Organizer Lighting Organizer automates the task of ensuring the right amount of light is available in a design. As different design options are investigated it enables decisions on lux levels, lumen, lighting, brightness, electrical installation, light fittings, ceiling fittings, lighting plans, fixed and variable lighting, lighting comfort, living and working spaces, etc.

Ventilation Optimizer This application checks against building codes and client needs, considering clean air volumes, ventilation capacity, airflow capacity, air handling units (AHU), ventilators, supply, exhaust and return ducts, vents, detectors etc, as prescribed by room occupancy or space type and number of people capacity.

Review Accessibility Evaluator This application assists in checking the accessibility compliance of a building design for wheelchair or other disabled access. The software will check corridor widths, room access, ramps, door widths, multi floor or level access via lifts and lift dimensions, disabled toilet and shower facilities, etc.

Daylight Ratio Evaluator Checks daylight area per room inside the BIM model and assesses illumination, energy use and solar glare/ reflection regarding modelled floor areas, positioned glazing, glass area, artificial lighting, comfort and brightness

Spatial Requirements To ensure a design meets the functional requirement of the client’s brief and building regulations.

Spatial Requirements Assistant automates the checking of the Revit model against set criteria.

The Spatial Requirements Assistant features: • Accepts various functional requirement inputs based on Revit’s room occupancy types and user defined rule sets for custom requirements such as

Energy Assessor Minimizing energy, meeting regulatory requirements and occupant satisfaction is a modern design essential. Vabi Energy Assessor, comes with a great pedigree and works inside the Revit BIM model to assess monthly and yearly energy costs, electricity use, gas use, renewables use, CO2 emissions, green building rating, EPC, energy performance, heating, cooling, HVAC, thermal insulation and airtightness.

Conclusion Vabi’s new dashboard is more than just a building analysis tool and its approach to the delivery of its applications is truly unique. The relatively low cost of access as well as flexible subscription for third party add-ons are also untried in the Autodesk developer community. While these are all inventive it will be interesting to see just how popular they prove, there should be at least one or two listed here that appeal to most people.

board display, which is a highly desirable capability. It is now possible, at a glance, to see how well the current design conforms to many performance criteria, no training required. The benefits for building performance feedback in the iterative design process are also clearly obvious, however some of the analysis tools do require users to ‘prepare the model’, such as allocating room spaces within the Revit model, to provide important spatial information for downstream analysis.

The market will have to decide if the ‘portion size’ of the Vabi applications is right for

the incremental subscription fee it is charging. It will depend on how much benefit can be derived from their use. It strikes me as a sign of the company’s confidence in its products that the apps can be extensively trialled before purchase and turned on / off on a monthly basis. Vabi is actively encouraging feedback and wants customers to help drive development of its modules.

The buy / download system appears to be set up for individual or small firm access, for large firm global access to application suites, it is best to contact Vabi directly. www.AECmag.com

Comment

The narrative potential of daylight analysis Architects are using daylight analysis to better tell the story of a design to clients. Together, renderings and analysis build a more complete — and more compelling — case for design, writes Carl S. Sterner.

A

s architects, we are trained to use daylight to shape the character and experience of the spaces we create. We are skilled at exploring the visual, experiential aspects of daylight. We are adept at creating striking renderings — those beautiful depictions of light and shadow that viscerally communicate the character of the design.

These images are easily woven into the narrative of our design intent, and easily understood by clients.

But there is a critical element missing from this medium: the practical issue of whether the daylight actually works. Are our renderings actually representative of the lighting in the space, or are they evocative works of fiction? Do they capture typical conditions or a unique moment? Does our design actually supply the lighting required?

Renderings are unable to answer outcomes-based questions: Is this classroom well-lit for most occupied hours? Is there glare in the conference room? Are roof lights an effective strategy for improving daylighting in our office? How do they compare 42

to light shelves? Should there be more glass on the north or south façade? A good design needs more than poetry: it needs to work — not just sometimes, at that magic golden hour, but every day, every hour.

These are questions, of course, for which daylight analysis is well suited.

Nearly every space has lighting requirements, and day-lighting analysis can show how well a design meets those needs. It can help designers proactively identify problem areas, measure progress toward project goals, and compare design options.

Physics-based analysis allows designers

to build performance into the very fabric of their designs, and thereby weave a strong objective case into each concept.

This insight is increasingly easy to get, thanks to new tools that make daylight analysis accessible, quickly enough to be an integral part of the design process. www.AECmag.com

The point is that it is also a great tool for communication — for telling the story of a design to clients. The combination of qualitative and quantitative elements is especially www.AECmag.com

powerful. Renderings put an expressive face on otherwise opaque numbers; and analysis backs up the vision with clear, impartial data. Together they build a more complete — and more compelling — case for a particular design.

Take, for example, a recent project by Allan Joyce Architects (pictured). The firm was approached to retrofit a Tearoom at the Royal Horticultural Society Gardens in Harlow Carr, UK, with an eye toward improving day-lighting and comfort. The building’s existing south and west glazing took advantage of views, but contributed to uncomfortable overheating and unfavorable glare. The architects developed a series of changes that they believed would greatly improve the occupants’ experience — but wanted to bolster this intuition with metrics.

Their presentation put renderings and analysis side-by-side to communicate the impact of their proposed changes, both qualitatively and quantitatively. The renderings suggested an experience that was confirmed by the data.

800 and above

“Our client wanted to understand in detail how the proposed changes would provide the outcomes that they were after,” Toby Evison, architect at Allan Joyce Architects said. “We used a combination of rendering and analysis software to produce a report documenting the before and after conditions. Our client was delighted — they could easily comprehend the effect of the design proposals and this directly informed their decision making.”

Mr Evison sees analysis as an important tool in the architect’s kit: “As architects working on a wide range of projects for an equally wide range of clients, it is important that we can draw on a comprehensive set of tools to communicate our ideas.”

Architects are in the unique position of articulating the vision of a design while attesting to its technical feasibility and ultimate performance. The right combination of tools and imagery allows us to speak to both aspects of design, and to weave them together into a rich and compelling narrative.

n the 26th August 2013 Rafael Viñoly’s ‘Walkie Talkie’ building at 20 Fenchurch Street, London, was hitting the headlines for all the wrong reasons. A beam of sun light reflected off the 525 ft skyscraper’s concave-glass façade had just cracked tiles, blistered paint and melted parts of a Jaguar XJ as its temperature soared to a staggering 110°C. To stop this so-called ‘deathray’ damaging neighbouring properties, brise soleil sunshades had to be retrofitted to the façade. The cost to the developer was a www.AECmag.com

reported £10m (5% of the cost for the entire build).

The destructive power of the Walkie Talkie’s ‘deathray’ re-affirms how important it is for architects to accurately predict how their designs might impact the immediate environment in densely populated urban areas.

They need to ask if the design will become a danger to those around it, not through poor structural integrity, or sloppy construction, but through a lack of understanding of material and lighting behaviours in its real-world environment. www.AECmag.com

p44_45_46_47_AEC_MAYJUNE15_lightworks.indd 45

Physically-based rendering Physically based rendering, or physically based simulation, provides architects, designers and civil engineers with feedback on how their designs will behave in real-world environments.

This includes how materials interact with light sources—both natural and artificial—how light is reflected and refracted, where shadows hit and if there are any points where the material or lighting is not enhancing the environment but damaging it instead.

In the past it was common to review the

lighting and physical properties of a design after several aesthetic iterations had been made. This delay was often due to the time taken to create these visuals — up to 24 hours for a single render that showed a photorealistic still of the proposed design.

It is now easy to review the properties of the materials, lighting and environmental factors at any point in the design process with physically based rendering.

With tools like Iray+ now more widely available in packages like 3ds Max, access has become cheaper and easier for May / June 2015

designers. At the same time, processing power has become more affordable, allowing for more real time rendering.

Designers can thus create as many iterations as required.

In the case of 20 Fenchurch Street a potential problem with reflections from the concave frontage was identified during the review of the second design iteration, but it was believed that the sun would not reach a great a height, or intensity, than the example used in the model. The reflected light it was assumed would, therefore, never form a concentrated beam.

If the designers had combined physically based rendering with interactive render modes the design could have been continually tweaked and reviewed to make sure this hypothesis was correct.

In focus Design visualisation specialist Lightworks decided to do its own physics experiment into the deathray phenomenon. It took a detailed model of London around the Fenchurch Street area, inputted the exact longitude and latitude of the building, set the time and date to midday on 26 August 2013 (when the deathray occurred), and using Iray+ inside of 3ds Max, set up a physical sun and sky model and added some physically based materials, such as glass, to the model.

Using the Irradiance mode in Iray+ for 3ds Max, the light energy was calculated in the scene — with a minimum and maximum lux value. As the time was moved closer to midday, a hotspot formed on the street, with a maximum lux value of about 500,000, which translated accurately to 110°C. Further modelling found that, had the designer increased the curvature of the building by as little as 10%, the light and the heat of the sun would have been focussed into a much smaller, much more intense hotspot that the company has dubbed the ‘ultimate deathray’. This could potentially be up to 30 times the power of sunlight. Which could have been enough to melt the tarmac on the street.

When undertaking lighting reviews it is important to analyse the diffuse and spec46

May / June 2015

p44_45_46_47_AEC_MAYJUNE15_lightworks.indd 46

ular reflected light; in the case of 20 Fenchurch Street it was the specular component of the light — or caustic — that created the concentrated beam.

The combined analysis of diffuse and specular light, was, until recently, hard for designers to achieve as most applications cannot measure the specular light; it is a key feature in the Iray suite of products.

This sentiment was echoed by the building’s architect Rafael Viñoly in an interview with the Guardian newspaper, where he admitted that he predicted the building might reflect hot sun rays to the street below but “didn’t realise it was going to be so hot.”

“There was a lack of tools and software that could be used to analyse the problem

accurately,” he said.

However, Lightworks believes that with continued developments in visualisation technology and the combination of raytracing, real-time and interactive rendering, design review has become much more accessible across all areas of the product pipeline.

These visualisation programmes, when supported by scalable hardware options, means that architects and designers can easily set-up multiple interactions for review; making sure that minor changes to a building do not have a negative impact on its environment.

to 525 ft skyscrapers, the developments in physically based rendering provide information that can be used in a number of industries and applications, including automotive and green energy production.

In the case of energy production, a concentrated beam, can be specifically created and directed to an energy capture point close by, where it is then converted into electricity.

Had Rafael Viñoly and his team had access to tools like 3ds Max and Iray+ they might have been able to confidently predict the issues earlier in the design process, enabling them to specify a more absorbent glass or even an alternative design for the façade.
