Tools Rhino 3D, Vasari DIVA Vasari DIVA Vasari Equest

Inquiry Identify % of year above and below the comfort band (70-75 deg F).

Identify % of year above 60% relative humidity.

Identify summer and winter primary wind direction and velocity.

Identify hot and cold site exposures.

Identify maximum glazing area needed by exposure to adequately illuminate perimeter zones if massing is set, and iterate between floor plate outlines if massing is flexible.

Run first energy and load analysis.

Discuss results and use them to question Step 2 massing decisions.

Repeat steps 2 and 3 as needed.

Identify façade strategies using a range of geometric densities, depths, and bay sizes to generate a matrix of options.

Discuss the “sensitivity” of various variables to related performance outcomes.

Translate geometric complexities into their vertical and horizontal counterparts.

Identify three geometries representative of the range of variation (small-medium-large) in Rhino and model those in Vasari.

Repeat steps 4 and 5 as needed.

Export Vasari model of final design into Equest, apply daylight dimming sensors, add utility costs, and compare results against two baselines.

Baseline A – 90.1 building; Baseline B –status quo fully glazed building.

Repeat steps 2 thru 5 as needed based on baseline comparisons.

Activity Rhino 3DBuild zoning boundary and extrude to maximum building height. Build surrounding buildings as single surface masses.

VasariIdentify nearest weather station. Document climate data.

DIVAIterative runs of solar radiation analysis. Iterative runs of workplane illuminance analysis.

VasariBuild or transfer desired massing with proper floor count and glazing areas. Run energy analysis.

DIVAParametric runs using DIVA Grasshopper components.

VasariRun energy analysis and discuss trends within loads results. You will see more variation in the loads results than the energy results between façade options. While high performing facades reduce less than 5% of building energy consumption, they can reduce peak loads by up to 30%, resulting in lower HVAC first costs and potentially lower demand on power plants.

EquestRun energy analysis and discuss reductions between design and baseline cases.

Introduction

Comparisons for Benchmarking Existing Building (SHGC = 0.4) Typical Curtain Wall (SHGC = 0.7) Proposed Design (kWh)

1 - (Proposed / Baseline) x 100

Performance Report Heat Gain Reduction (%) v Existing Heat Gain Reduction (%) v Typical

Report how much more efficient the proposed design is over a code-minimum Baseline (theoretical)

Total Area of Glass (ft2) x Glass SHGC x Total Radiation (kWh) = Total Heat Gain

DIVA calculates cumulative solar radiation incident on the building surface (kWh/m2). Extract the following values from DIVA/GH.

Enter Total Heat Gain from above in the Proposed Design cell. Have GH simulate an alternate version of the design as the code-minimum option. For that option, model a vertical wall with 40% window-to-wall ratio (window area / total wall area, incl. window area)

Import data from GH. Importing Glass, Wall and Floor area is simply surface areas.

Calculating Total RadiationTo import Total Radiation, in GH, first find a way to multiply the simulated kWh/m2 values by the the glass area within each threshold radiation threshold. One way to do this may be setting up threshold bands. For example, for all glass area between 500 and 600 kWh/m2, collect that glass area, and multiply by 550 kWh/m2. Do the same for all 100 kWh/m2 bands of data, and sum all kWh values from all radiation thresholds to obtain the total kWh for the entire wall.

Calculating Heat GainIf all three floors of the E building are being served by a single mechanical system, we do not need to calculate multiple heat gain values for each zone, we can sum all of the facade heat gain and assume the cooling load on the single rooftop system.

Perimeter Floor AreaBuildings typically divide perimeter zones seperately from core zones (15 to 30 foot perimeter depth). For perimeter area, sum the floor area on each floor within 15 feet of the exterior wall, i.e. building width x 15 feet floor depth x number of floors.

ENERGY & DAYLIGHTING ANALYSIS (Vasari/DIVA/EnergyPlus)

HVAC

Typical

Similarities Arising from Vasari’s Inability to Account for Change in

Lighting Energy

The lighting energy in the three scenarios is the result of having lights switched on from 8:00am to

5:00pm everyday of the year, regardless of daylight availability.

This is a limitation of user input options in the Vasari analysis

toolset, and a primary reason that, while good for preliminary

decisions early in the design process, Vasari is not a true

energy modeler.

Total Area of Glass (ft2) x Glass SHGC x Total Radiation (kWh) = Total Heat Gain

DIVA calculates cumulative solar radiation incident on the building surface (kWh/m2). Extract the following values from DIVA/GH.

Enter Total Heat Gain from above in the Proposed Design cell. Have GH simulate an alternate version of the design as the code-minimum option. For that option, model a vertical wall with 40% window-to-wall ratio (window area / total wall area, incl. window area)

Import data from GH. Importing Glass, Wall and Floor area is simply surface areas.

Calculating Total RadiationTo import Total Radiation, in GH, first find a way to multiply the simulated kWh/m2 values by the the glass area within each threshold radiation threshold. One way to do this may be setting up threshold bands. For example, for all glass area between 500 and 600 kWh/m2, collect that glass area, and multiply by 550 kWh/m2. Do the same for all 100 kWh/m2 bands of data, and sum all kWh values from all radiation thresholds to obtain the total kWh for the entire wall.

Calculating Heat GainIf all three floors of the E building are being served by a single mechanical system, we do not need to calculate multiple heat gain values for each zone, we can sum all of the facade heat gain and assume the cooling load on the single rooftop system.

Perimeter Floor AreaBuildings typically divide perimeter zones seperately from core zones (15 to 30 foot perimeter depth). For perimeter area, sum the floor area on each floor within 15 feet of the exterior wall, i.e. building width x 15 feet floor depth x number of floors.

HOW TO GENERATE FLAT PATTERNS FOR SHEET METAL PARTS:

WHEN THE SHEET METAL IS PUT THROUGH THE PROCESS OF BENDING THE METAL AROUND THE BEND IS DEFORMED AND STRETCHED. AS THIS HAPPENS YOU GAIN A SMALL AMOUNT OF TOTAL LENGTH IN YOUR PART(BEND ALLOWANCE). LIKEWISE WHEN YOU ARE TRYING TO DEVELOP A FLAT PATTERN YOU WILL HAVE TO MAKE A DEDUCTION FROM YOUR DE-SIRED PART SIZE TO GET THE CORRECT FLAT SIZE(BEND DEDUCTION).

BEND DEDUCTION:

THE BEND DEDUCTION IS DEFINED AS THE MATERIAL YOU WILL HAVE TO REMOVE FROM THE TOTAL LENGTH OF YOUR FLANGES IN ORDER TO ARRIVE AT THE FLAT PATTERN.

BEND ALLOWANCE:

THE BEND ALLOWANCE IS DEFINED AS THE MATERIAL YOU WILL ADD TO THE ACTUAL LEG LENGTHS OF THE PART IN OR-DER TO DEVELOP A FLAT PATTERN.

TYPES OF BENDING:

AIR BENDING:

IS THE MOST COMMON TYPE OF BENDING PROCESS USED IN SHEET METAL SHOPS TODAY. IN THIS PROCESS THE WORK PIECE IS ONLY IN CONTACT WITH THE EDGE OF THE DIE AND THE TIP OF THE PUNCH. THE PUNCH IS THEM FORCED PAST THE TOP OF THE DIE INTO THE V-OPENING WITHOUT COMING INTO CONTACT WITH THE BOTTOM OF THE V.

COINING:

IS A BASIC TYPE OF BENDING IN WHICH THE WORKPIECE IS STAMPED BETWEEN THE PUNCH AND DIE. BOTH THE PUNCH TIP AND THE PUNCH ACTUALLY PENETRATE INTO THE METAL PAST THE NEUTRAL AXIS UNDER A HIGH AMOUNT OF PRES-SURE. THE TERM COINING COMES FROM THE IDEA THAT WHEN IT COMES TO MONEY EACH METAL COIN IS MADE EXACT-LY THE SAME AS THE LAST DESPITE BEING MASS PRODUCED. FROM THIS IDEA THE NAME COINING WAS APPLIED TO THE BENDING METHOD WHICH CREATES ACCURATE BENDS CONSISTENTLY.

BOTTOM BENDING:

HAS SIMILARITIES TO BOTH AIR BENDING AND COINING. IN THIS PROCESS THE DIE ANGLE SHOULD MATCH THE INTEND-ED ANGLE OF THE WORK PIECE, ADJUSTING A FEW DEGREES FOR SPRING BACK, HENCE THE EXISTENCE OF 88 DEGREE TOOLING TO ACHIEVE 90 DEGREE ANGLES. THE WORK PIECE IS FIRST BOTTOMED AGAINST THE DIE, THEN THE RADIUS OF THE PUNCH IS FORCED INTO THE WORK PIECE WHICH ACHIEVES THE ANGLE OF THE PUNCH, IT IS THEN RELEASED AND THE WORK PIECE SPRINGS BACK TO MEET THE DIE AGAIN. UNLIKE COINING HOWEVER THE MATERIAL IS NOT UN-DER SO MUCH TONNAGE ..THAT THE METAL FLOWS. BECAUSE OF THIS THERE IS STILL SPRING BACK WHICH MUST BE COMPENSATED FOR.

FURTHER WORK

HOW TO GENERATE FLAT PATTERNS FOR SHEET METAL PARTS:

WHEN THE SHEET METAL IS PUT THROUGH THE PROCESS OF BENDING THE METAL AROUND THE BEND IS DEFORMED AND STRETCHED. AS THIS HAPPENS YOU GAIN A SMALL AMOUNT OF TOTAL LENGTH IN YOUR PART(BEND ALLOWANCE). LIKEWISE WHEN YOU ARE TRYING TO DEVELOP A FLAT PATTERN YOU WILL HAVE TO MAKE A DEDUCTION FROM YOUR DE-SIRED PART SIZE TO GET THE CORRECT FLAT SIZE(BEND DEDUCTION).

BEND DEDUCTION:

THE BEND DEDUCTION IS DEFINED AS THE MATERIAL YOU WILL HAVE TO REMOVE FROM THE TOTAL LENGTH OF YOUR FLANGES IN ORDER TO ARRIVE AT THE FLAT PATTERN.

BEND ALLOWANCE:

THE BEND ALLOWANCE IS DEFINED AS THE MATERIAL YOU WILL ADD TO THE ACTUAL LEG LENGTHS OF THE PART IN OR-DER TO DEVELOP A FLAT PATTERN.
