1. What propelled you to look for a daylighting tool?

We know that daylight is good for people – both for their health and happiness. That’s a challenge indoors, where we spend most of our time. So we help make it easy to get quality daylight into new and existing buildings. Lots of that is based on intuition, however there’s an important role for analytic tools. That’s because how daylight varies with the climate, and we use annual sky conditions to better understand how to achieve visual comfort for occupants. There are also innovative redirecting glazing treatments that we just don’t have enough experience with to guess about.

2. Before LightStanza, what other daylighting/lighting software did you use?

We have tried several tools at Forte to predict daylight. DIVA for Rhino is a fine interface for Daysim, and IES VE works okay for Radiance. We have tried Radiosity tools such as Licaso for ElumTools and Sefaira. It was a relief to find the best parts of these tools available in LightStanza.

3. What hurdles or problems did you have with your previous software?

Radiance is the gold standard in simulation, so we rely on platforms to provide transparent access to the engine. That makes Sefaira and Licaso of limited value for us. They are good tools for simple projects but don’t offer the capability to process specular treatments – a must-have for most state-of-the-art daylight solutions. DIVA is great but also required we purchase and learn Rhino. When we last used the software it was also using Daysim to interface with Radiance. IES VE has improved with the latest release, but still has profound limitations for visualization. Having the thermal zones of our energy model wrapped up with the daylight plates means we end up post-processing our results files and generating our own maps – a time-consuming process.

4. What made you decide to use LightStanza?

LightStanza is smart in tackling the tough problems in daylight while also delivering an intuitive interface. It handles window protection and allows us to access custom scattering files for different products. Most of us are familiar with SketchUp so that was not a problem. The cloud computing also delivered faster results than running Radiance on our PCs. Getting access to the illuminance outputs and useful renderings also integrates with our workflow.

5. What was your experience when switching or getting started with LightStanza?

At first I was pretty confused because it seemed so simple. I had to remember SketchUp a bit to get started, but then I was impressed with how quickly I was looking at climate-based results. That would have taken me an over-night computation in the past.

6. Can you describe one or two of LightStanza’s features or functions you feel are most useful for your work?

Easily assigning glazing types is huge with the number of glazing protections and treatments on a typical high-performance project. We also can trust in the algorithms used by LightStanza for shade behavior based on occupant comfort.

7. How has LightStanza improved (or how do you see it improving) your projects and business?

We often see SketchUp way before we get Revit, so it’s a nice tool for early design. That’s when we’re also most likely to impact some of the first assumptions around massing and orientation. It gives us quantitative information that we can use to assign performance impacts for occupants. And at a phase of the project when very few decisions have been made.

8. Would you use LightStanza on future projects and/or recommend the tool to other colleagues? If so, why?

We are able to work with the LightStanza team on our projects in a way unlike other tools we use for daylight. Or simulation in general for that matter. We are confident to use their software because we know they are continuing to push their tool to do more. So it’s not just about choosing the best tool today – we’re trying to choose the best tool for next year. LightStanza looks very promising in that category.

1. What propelled you to look for a daylighting tool?

Sustainable & passive design principles are the driving force behind all of our firm's projects. We consider appropriate levels of natural daylight to be an essential design parameter, since this will have a major impact on the day-to-day experience of building users. Designing with daylight is conceptually simple, but "good" daylight levels are often poorly understood in the construction industry, and we were having challenges implementing [other PC-based software] into our fast-paced workflow. The alternative to using computer simulation software was building a scaled physical model. In addition to being arduous and time-consuming to produce, physical models lack the precision of virtual daylight simulations and only provide a rough rendering of how light will affect the interior spaces.

2. What hurdles or problems did you have with your previous software?

We are a Mac-based office so we had to switch between operating systems to get [Software Program 1] or [Software Program 2] running, which slowed down the design process. [The outdated software] is longer supported by its creators (the last version was in 2011), was difficult to use, and required many workarounds to generate acceptable results. The challenging modeling environment meant that we couldn't easily recreate complex geometries that might affect daylighting levels. We would often approximate geometries in this case, which reduced the accuracy of the simulation data.

3. How did these issues affect your projects and business?

Daylighting simulations were selectively implemented in our design process due to the time-consuming nature of these models & simulations. It slowed down our design process, and led to less responsive design feedback than we would have liked. As a result we often spent extra time at our own cost to sufficiently model these projects because we are committed to delivering quality work.

4. What made you decide to use LightStanza?

Several key factors made us adopt LightStanza wholeheartedly:

  • A. No need to learn new modeling software

    The fact that Sketchup models are used for LightStanza meant that we could save lots of time by using the models that we'd already constructed for design purpose, instead of having to completely recreate our projects from scratch in [the other PC-based software]. This also meant that we no longer had to switch to Windows and back again to assemble the graphics generated from our analysis.

  • B. Lots of useful daylighting data presented in a meaningful way

    We were floored when we saw the depth of information we received from a single simulation run. We used to toil over the graphic outputs from [our old software], overlaying them into floor plans using three different pieces of software, and then repeating the process for as many different metrics we needed to show. Setting up the parameters for the simulations are incredibly easy, and we are now able to make design changes with a much faster turnaround.

  • C. Cloud based means less reliance on our machines to set up and run simulations

    We used to run simulations on our computers, since there weren't many other options. This slowed down processing speed significantly, so we generally waited until the end of the day or worked on tasks that didn't require a computer while the simulations were running. LightStanza's cloud-based simulation processing means that we can get results quickly without interrupting our workflow.

  • D. It's so much faster to do everything

    Our process has greatly benefited from using this software, making it easier for us to achieve sustainability goals in our projects.

5. What was your experience when switching and getting started with LightStanza?

It was super easy: the only difficult part was feeling a bit overwhelmed with the vast amount of data that we were suddenly able to generate! After running a few simulations we understood which metrics were most relevant to our projects, and quickly put them to good use. We use SketchUp extensively in our work, so we didn't have to learn anything new for the modeling. The LightStanza team was very supportive and quick to respond to questions.

6. Can you describe one or two of LightStanza's features or functions you feel are most useful for your work?

LEED 2009 Compliance-The simulation method for this daylight credit just got MUCH easier. On past projects, we would often opt for spreadsheet calculations or site measurements, simply because it was too time consuming to do a full building simulation.

Renderings with false colour overlays-These give a great visualization of how high or low the daylight levels are, especially after setting the maximum threshold to identify glare issues.

Comparison feature between design variations-We like using this feature to see how our different design option compare for daylight performance.

7. How has LightStanza improved your projects and business?

It has saved us time while delivering very precise data, allowing us to work more efficiently. It has improved our capacity to deal with daylighting for our projects, and it gives us an edge in terms of design services offered.

8. Would you use LightStanza on future projects and/or recommend the tool to other architects? If so, why?

Our firm operates a bit differently because we are deeply rooted in sustainability and high performance building metrics drive our designs. We plan to use this on all of our future projects, because we feel that daylight performance is a big piece of the puzzle that helps us deliver high quality projects. We would recommend this tool to like-minded architects and designers, and we can confidently offer daylight simulation assistance to firms that seek this expertise to improve their projects.

1. What propelled you to look for a daylighting tool?

We were already trying to incorporate daylighting as a design tool before LightStanza but struggled to have meaningful, trustworthy, and accurate results in the necessary amount of time to incorporate into the tight project schedules.

2. What hurdles or problems did you have with your previous daylight software?

We often struggled with the accurate transfer of an existing model into the simulation software and the modeling tool that was offered within [the software] was cumbersome and not easy to use. We also didn't have a good understanding of all of the different simulation inputs or settings and couldn't easily control the variables we needed/wanted to control. Additionally, it was hard to trust the results without a comprehensive understanding of inputs and it wasn't easy to export results in a user-friendly or appropriate graphic format. Overall, the tool was not web-based so any simulations would bog down machines and take a very long time to run, often preventing us from performing enough simulations to be useful on projects.

3. How did these issues affect your projects and business?

It prevented us from incorporating meaningful daylighting results/input on many projects to influence early design.

4. What made you decide to use LightStanza?

LightStanza is cloud-based so immediately solves the problem of bogging down our internal machines, so we can launch simulations and continue to work simultaneously. Additionally, the user-interface is much more intuitive and user-friendly for architects.

5. What was your experience when switching and getting started with LS?

It was a very simple transition to using LightStanza and with each update of the interface, it becomes a stronger tool and more geared toward its end-users' needs.

6. Can you describe one or two of LS's features or functions that you feel are most useful to you in your work?

It's easy to go from working in SketchUp to uploading progress models in order to quickly test concepts. My favorite feature to date is the ability to test multiple concepts by turning on/off components, changing finishes and colors all within the LightStanza interface so you don't have to go back to the original model each time you want to test something new.

7. How has LS improved your projects and business?

LightStanza truly meets our needs for an early-design daylighting tool. It has successfully helped us inform early design concepts on projects to better realize our daylighting design goals. From a business standpoint, we're able to keep more of the daylighting design scope in-house and the tool helps us better work with engineers for meeting sustainability goals collaboratively.

8. Would you use LS on future projects and/or recommend the tool to other architects? If so, why?

Yes, we plan to use LightStanza ongoing on projects, predominantly for early design input and we continue to recommend the tool to other architects.

James Woodall, Sustainable Design Specialist
HCMA Architecture + Design
Vancouver, BC

1. What propelled you to look for a daylighting tool?

HCMA is constantly seeking new and innovative methods and means to assess, evaluate and ask questions of our own designs. The ability to carry out these processes in-house offers great potential to increase our capability and add reassurance to our design decisions. Daylighting is an important consideration in our design process, and one that we look to explore and optimize.

2. Before LightStanza, what other daylighting/lighting software did you use?

Immediately prior to LightStanza we had used daylight analysis as part of a wider analysis software package. Until this point we had not found it viable to carry out this type of analysis in-house.

3. What hurdles or problems did you have with your previous software?

The previous software provided a useful overview of daylighting levels anticipated at concept stages of design, but lacked capability in carrying out more rigorous detailed analysis.

4. How did these issues affect your projects and business?

Our potential to evaluate our building designs was 'capped' by this limitation in capability.

5. What made you decide to use LightStanza?

We wanted to explore use of a more powerful tool that would provide us with higher levels of capability to answer the questions we were asking during the design process.

6. What was your experience when switching or getting started with LightStanza?

From the outset, we were particularly impressed by the ability of LightStanza to generate a range of detailed simulations with a rapid turnaround. LightStanza is an easy-to-use and very informative tool which offers us an invaluable ability to fit seamlessly within our existing design process.

7. How has LightStanza improved (or how do you see it improving) your projects and business?

LightStanza provides very detailed design feedback that allows us as a firm to greatly increase our potential to make well-informed design decisions.

Travis McDaniel, M.S. EIT, LEED Green Associate, Net Zero Systems Engineer
Point Energy Innovations
San Francisco, CA

1. What propelled you to look for a daylighting tool?

Point Energy Innovation's search for a daylighting tool was driven by our desire to be the premier engineering consultancy for sustainable building design. To achieve this we are fostering a new design paradigm that integrates best in class comfort, health, efficiency, and affordability. Lighting quality is a critical component of this new building standard, and LightStanza allows us to quantify and visualize parameters from glare to daylight autonomy in our designs.

2. Before LightStanza, what other daylighting/lighting software did you use?

As a newer firm we were hunting for software that met our goals. We had previously relied on our experience of what we knew to be qualitatively true, sometimes substantiated by daylighting plugins of a full featured energy modeling program or other standalones that utilized some functions of Radiance. We found these programs do well at a couple things, but we needed something that performed great at many things.

3. What hurdles or problems did you have with your previous software?

Not enough freedom to customize our designs or test all the variables we would like.

4. How did these issues affect your projects and business?

Point Energy Innovations strives to convey complex ideas to clients in a way that is relevant for their decisions. Other programs required us to present information with limitations. With LightStanza we can fully convey ideas in a style clients appreciate, namely through customized quantitative LightStanza results combined with verbal explanation and photos of past projects.

5. What made you decide to use LightStanza?

We heard of LightStanza from our industry partners, and after putting it through its paces on an actual project and receiving positive client feedback we decided it was the tool for us.

6. What was your experience when switching or getting started with LightStanza?

With any program there is a learning curve. But the well designed user interface allows users to familiarize themselves quickly. It was evident from early on a lot of thought had been put into the program and we are very pleased with the responsive customer support.

7. Can you describe one or two of LightStanza's features or functions you feel are most useful for your work?

Two of the most useful features are the Useful Daylight Illuminance plan views and three dimensional glare rendering. Both of these convey the important concept of occupant visual comfort that is so often overlooked. We know conceptually that occupants want daylighting without the discomfort of glare, but rarely are these thought about critically. The Point Energy Innovations team has always understood the client's incentive to provide, and designed for, excellent occupant visual comfort, and now LightStanza allows us to hone the ideal lighting strategy. To this end, numerical results presented in colorful and graphical form provide both client and designer quick initial understanding and detailed information at the same time.

8. How has LightStanza improved (or how do you see it improving) your projects and business?

LightStanza allows us to add another premier service to our repertoire. Point Energy Innovations is committed to better design by thinking about buildings as an integrated and interdependent whole as opposed to a collection of disjointed systems. As HVAC consultants we have a good handle on mechanical systems and efficiency, but visual and thermal comfort, occupant health, and affordability are equally important. Lighting is connected to occupant productivity and thermal comfort, as much as it is to HVAC system sizing and energy efficiency; this is why they deserve our attention and how LightStanza has improved our business.

9. Would you use LightStanza on future projects and/or recommend the tool to other architects or colleagues? If so, why?

Yes. We have committed to purchasing a license and hope to see the product grow even further as we use it on a majority of our projects.

1. What propelled you to look for a daylighting tool?

Point Energy Innovation's search for a daylighting tool was driven by our desire to be the premier engineering consultancy for sustainable building design. To achieve this we are fostering a new design paradigm that integrates best in class comfort, health, efficiency, and affordability. Lighting quality is a critical component of this new building standard, and LightStanza allows us to quantify and visualize parameters from glare to daylight autonomy in our designs.

2. Before LightStanza, what other daylighting/lighting software did you use?

As a newer firm we were hunting for software that met our goals. We had previously relied on our experience of what we knew to be qualitatively true, sometimes substantiated by daylighting plugins of a full featured energy modeling program or other standalones that utilized some functions of Radiance. We found these programs do well at a couple things, but we needed something that performed great at many things.

3. What hurdles or problems did you have with your previous software?

Not enough freedom to customize our designs or test all the variables we would like.

4. How did these issues affect your projects and business?

Point Energy Innovations strives to convey complex ideas to clients in a way that is relevant for their decisions. Other programs required us to present information with limitations. With LightStanza we can fully convey ideas in a style clients appreciate, namely through customized quantitative LightStanza results combined with verbal explanation and photos of past projects.

5. What made you decide to use LightStanza?

We heard of LightStanza from our industry partners, and after putting it through its paces on an actual project and receiving positive client feedback we decided it was the tool for us.

6. What was your experience when switching or getting started with LightStanza?

With any program there is a learning curve. But the well designed user interface allows users to familiarize themselves quickly. It was evident from early on a lot of thought had been put into the program and we are very pleased with the responsive customer support.

7. Can you describe one or two of LightStanza's features or functions you feel are most useful for your work?

Two of the most useful features are the Useful Daylight Illuminance plan views and three dimensional glare rendering. Both of these convey the important concept of occupant visual comfort that is so often overlooked. We know conceptually that occupants want daylighting without the discomfort of glare, but rarely are these thought about critically. The Point Energy Innovations team has always understood the client's incentive to provide, and designed for, excellent occupant visual comfort, and now LightStanza allows us to hone the ideal lighting strategy. To this end, numerical results presented in colorful and graphical form provide both client and designer quick initial understanding and detailed information at the same time.

8. How has LightStanza improved (or how do you see it improving) your projects and business?

LightStanza allows us to add another premier service to our repertoire. Point Energy Innovations is committed to better design by thinking about buildings as an integrated and interdependent whole as opposed to a collection of disjointed systems. As HVAC consultants we have a good handle on mechanical systems and efficiency, but visual and thermal comfort, occupant health, and affordability are equally important. Lighting is connected to occupant productivity and thermal comfort, as much as it is to HVAC system sizing and energy efficiency; this is why they deserve our attention and how LightStanza has improved our business.

9. Would you use LightStanza on future projects and/or recommend the tool to other architects or colleagues? If so, why?

Yes. We have committed to purchasing a license and hope to see the product grow even further as we use it on a majority of our projects.

1. What propelled you to look for a daylighting tool?

Needed better ways to evaluate glass percentages/exterior wall design.

2. Before LightStanza, what other daylighting/lighting software did you use?

Diva for Rhino

3. What hurdles or problems did you have with your previous software?

Installation and troubleshooting were difficult
No support
Fairly slow
Had to manually run various studies and present results

4. How did these issues affect your projects and business?

Not necessarily a good fit for us initially - we don't have much time to spend.

5. What made you decide to use LightStanza?

Saw potential for a simpler, web based tool with more understandable graphics and output.

6. What was your experience when switching or getting started with LightStanza?

Works very well with familiar tools (SU, web interface)
Setting and graphics were easy to understand

7. Can you describe one or two of LightStanza's features or functions you feel are most useful for your work?

The Annual results grid allows a single view snapshot of how your design does on the various metrics that have been developed to measure daylight. This allows you to easily build understanding of the problem and the various trade-offs between different solutions. Other tools we have used require multiple setups and model runs and then time consuming collation of results.

8. How has LightStanza improved (or how do you see it improving) your projects and business?

Has allowed us to quickly study options and understand daylighting in the early phases of our project. Having easy to produce real data and visualizations to show to design teams helps educate them about good daylighting design and make a strong case to the clients. For example, we were able to use LightStanza to suggest refinements to the design of a large overhangs and hanging louvers for a large dining facility in a corporate office building. These studies also allowed us to justify these elements and show the qualitative and quantitative improvements they are making to the project.

9. Would you use LightStanza on future projects and/or recommend the tool to other architects or colleagues? If so, why?

Yes, it is a very easy to use and quick tool that can be used in conceptual design to improve understanding of daylighting. It doesn't require any time to install and is easy to start without any time consuming training. The support provided by Lightstanza is also excellent which is especially important for non experts.
