Sombreado dinámico PROF RUDY PIEDRA

# data[].attributes.attachment_link.readable_text
With large and complex models, the app automatically detects when a calculation is taking too long to be interactive and will try to degrade appropriately. For example, if the detailed shading takes longer than 200ms to complete, it will try to use a simpler method to maintain the dynamic feedback. If the simpler method takes longer than 200ms, it will stop trying to dynamically update until you finish dragging and release the pointer. Sometimes the browser or system might be busy with something else when you drag, causing it to temporarily stop dynamic updates even on a relatively simple model. However, as soon as the calculations return back to speed, the dynamic update will resume automatically.

Background

I started out using pretty straightforward ray-tracing for occlusion testing, which is pretty flexible and allows it to work with any type of triangulated geometry. Whilst there is some scope for optimising both the model and the intersection testing techniques used, and maybe WebGL2 or WebGPU could assist in the future, at this stage it seems unlikely that such an approach will be fast enough for highly dynamic feedback on anything other than the simplest of sites.

However, by simplifying the obstructions to just rectilinear boxes, it can run in very close to real-time - try it out for yourself. Using highly optimised axially-aligned bounding box intersections works astoundingly well, even with several hundred boxes and on a reasonably good phone or tablet.

This is particularly interesting as it suggests that the voxelisation of complex models into tiny rectilinear cells might just be the way forward, allowing for real-time dynamic shading calculations on geometry of any complexity. Why this is interesting is because many fluid dynamics calculation engines require a similar approach to complex geometry. Perhaps there is some synergy there to be exploited.

It turns out that the real bottleneck in terms of speed is dynamically updating the SVG sky segments in the 2D Sun-path chart. You can see this for yourself by choosing a small angle for the sky subdivision (say 2 degrees), closing the SHADING MASK overlay by clicking on its title bar (it will ignore update requests when closed), and then dragging the 3D Sun-path around the site. After a second or so, the updating should become significantly faster and smoother (it takes the JavaScript compiler time to re-adjust its run-time optimisations). I will look into this further, but it may be that I have to use WebGL for the 2D chart as well.

Interesting Features

Apart from the actual shading, the first potentially interesting feature of this app is the ability to select and interactively manipulate the obstruction blocks and the shading mask.

To change the size of any block, simply click/tap on any of its bounding surfaces and then drag the appropriate arrow in the direction you want. To adjust the shading mask position, first click/tap on the small red dot at its center and then drag any of the manipulator arrows.

The circular manipulator in the center of a block allows you to change its position. When you position a block such that it is close to the face of another block, it will snap to a position which aligns with that face. By default, this only happens with other blocks that are physically near the block being manipulated. If you wish to snap to other blocks further away, make sure the toggle button with the picture of a magnet inside a globe is selected. Similarly, you can toggle center snapping on or off or even all snapping.

In additional to physically dragging things around, you can edit both the position and size of the currently selected block by clicking in the SELECTION: BLOCK overlay panel or the small button with a pencil in it. This will display the EDIT SELECTION panel, as shown in Figure 3.

View Manipulation

You can interactively adjust the 3D view of the model using a mouse, pen or stylus, or by touch on a tablet or phone. You can also use the items in the 3D View Settings popup.

NOTE: You can use the Shift and Ctrl/Meta keys to adjust the increment of each scroll event or key press.

Keyboard Modifiers

The Shift and Ctrl/Meta keys are used pretty extensively to modify interactive data entry. This applies to all increment buttons, scroll wheel motion, slider controls and input elements.

Shift Key:

Increases input to larger values, usually by ten times or significantly larger increments such as 1 month for dates and 1 hour for times.

Ctrl or Meta Key:

Decreases input to smaller values, usually by one tenth or the smallest reasonable increment such as 1 day for dates or 1 minute for times.

NOTE: You can use the scroll wheel to edit a data value when hovering over any slider, numeric input or even table rows that indicate their editibility.

With growing consensus about the economic and social costs of climate change, an increasing number of cities and states have set ambitious carbon reduction goals. When it comes to the built environment, advanced energy codes and policies have proven to be one of the most impactful opportunities for local governments to reduce energy consumption and carbon emissions. Currently, some fundamental adjustments are needed to our current energy code approach in order to recognize the growing number of technically viable pathways that can deliver low and zero energy buildings. As a building standard, Passive House offers one such clearly defined path to ultra-low energy performance using a proven technical approach.

Recognizing that the Passive House design standard can deliver a foundation for achieving zero energy performance in buildings, some jurisdictions are writing Passive House certification into codes as an acceptable alternative "stretch" code compliance pathway. Three states -  California, Massachusetts and New York - as well as the city of Denver have already incorporated or are looking to incorporate Passive House design principles into their building codes and policies as a way to achieve deep energy and carbon savings.

What is a Passive House building?

Passive House design principles, including super insulation, airtight envelope, thermal bridge free construction and right-sized, highly efficient mechanical equipment, are known to be an effective way to significantly reduce heating and cooling loads regardless of climate or building location. Both residential and commercial buildings designed and constructed to this standard perform 60-85% better (depending on climate zone and building type) on an energy consumption basis when compared to a code compliant building (International Energy Conservation Code IECC 2009). The Energy Use Intensities (EUIs) of Passive House design are so low, that it is relatively easy to turn a certified Passive House into a zero energy building with a small amount of onsite renewable energy (such as solar) generation. An added benefit: Low-energy buildings, especially those with low winter heating demands, have the potential to be more grid-friendly and resilient because of higher efficiency equipment and better thermal retention capabilities.

There are more than 250 Passive buildings from coast to coast, with the most significant gains coming from the multifamily housing sector, according to Passive House Institute US (PHIUS). While this represents a small fraction of all new construction, PHIUS+ Certified and Pre-Certified projects now total more than 2.5 million square feet across 2,300 units nationwide. The trend shows no signs of slowing down - especially as an increasing number of cities and states are recognizing zero energy and Passive House buildings as a way to achieve aggressive climate goals. PHIUS+ Certified buildings come in numerous shapes and sizes - from multi-story apartment buildings, office buildings, medical offices, educational centers and affordable housing.

PHIUS 2018

Meeting climate-specific zero energy and/or Passive House building performance requirements requires careful analysis. PHIUS+ 2015 was the first passive building standard to take a climate-specific approach. In 2018, PHIUS introduced PHIUS+ 2018. The update focuses on adding more nuance to the performance goals for different building types, and supporting an overall transition to renewable energy. Because size and occupant density influence the optimal path to a low energy building, the new criteria implement continuous adjustments for a range of different building sizes and occupant densities. Learn more about what changed between PHIUS+ 2015 and PHIUS+ 2018 here.

"Of course we open the windows!"

Wolfgang Erichson has been living in the Bahnstadt district of Heidelberg for three years and is very happy with his new place of residence. "It was pleasantly warm even on cold winter days," says Erichson. On the fire station premises the city administration presented its energy monitoring results together with the Passive House Institute. The two most important outcomes: the consumption of heating energy in the Bahnstadt district was extremely low. Simultaneously, the total energy consumption was only a third of that of conventional housing complexes. more

When it was inaugurated four years ago, the Raiffeisen Tower in Vienna was the first high-rise building in the world built to the Passive House Standard. Four years later, great progress has been made. This summer, in New York, around 350 students will move into a 26-storey dormitory, being built to the Passive House Standard. The structure of the 88 metre tall Passive House building "Bolueta" in Bilbao, Spain, will be completed within a few weeks. The architects of both these buildings will attend the 21st International Passive House Conference in April in Vienna to report on their exciting projects. more

News in brief

Smiling faces in Aberdeen

The new Rocking Horse Nursery of the Scottish University of Aberdeen brings many happy faces to the children and their teachers. They attribute this as much to the comfortable indoor climate as to the constantly available fresh air. The nursery is the first building in Aberdeen built to the Passive House Standard. The Director of the Passive House Institute, Dr. Wolfgang Feist, recently presented the certificate to the developers and their team.

From both the outside and inside, the single-storey nursery is a real eyecatcher with its wooden facade. Winters with long nights are common in Aberdeen. "The Passive House concept is the best solution for this situation", says Dr. Wolfgang Feist.
