Walls

Locations:

• Pretty much all around the periphery of the building. The “Mindo” as I have come to call my building (After my native language) is a brick structure on Mtl Stud wall
• Some places have stormfront curtain walls
• Interior walls that are a closed space make use of 2-hr fire resistant roles

Characteristics:

• Walls are designed to be thermally insulating and low thermal mass, with an R59 and Thermal mass of 7.
• Air gaps are used as insulators instead of foam, with a base of Brick with Metal Studs
• The assembly is uploaded below

Roof surfaces

Locations:

• The roof was only on the top of the building
• It has been designed as a green roof, to help combat urban heat island effect and keep the building cool.

Characteristics:

• The green roof will be on the whole “Level 4”
• The assembly was a blend of thickness for soil, for grass and drainage systems, as seen in below screenshot
• As for the roof itself, I picked a simple 2” inch thick roof with a 0.7 absorptance
• My roof is also going to make way for solar panels

Curtain Walls:

Locations:

• They are located on 1 side of the building for all three storeys.
• This has been strategically placed to ensure that visitors get optimum views and best daylight in our museum

Characteristics:

• Our exterior curtain walls have sunshades and interior overhangs, extending for 2 feet out and 1 feet inside respectively
• The glass is Triple Glazed 1/4 inch thick with an e value of 0.05, which gives a high VLT (0.55), Low SHGC (0.26), High R (3.70) and low Heat Transfer Coefficient (0.27) which facilitates good daylighting as well as good insulation from heat

Windows:

Locations:

• A lot of the sides of the building have good views. In line with my principle of daylighting and quality views, I installed large windows throughout the periphery of the building

Characteristics:

• These windows are tall (9 feet) and wider (12 feet) so that they go high up into the wall. allowing for light to come in and light the ceiling too
• The color of the glass is also adjusted to match the following target requirement for a Visual Light Transmittance of 0.8

Doors:

Locations:

• There are two primary doors for entering/exiting the building, which are large revolving doors
• This idea was borrowed from the East-Coast US building performance practice, where I feel that less energy is wasted in keeping a door rotating than in opening/closing
• (I need to make more doors for fire evacuation)
• I added single-door doors for the other rooms, ensuring they open on the inside

Characteristics:

Skylights

Locations:

• One skylight will be added to the top of the building, where you currently can see a conical roof

Characteristics:

• The purpose of the skylight is to illuminate the atrium

Shading/Sun control features:

Locations:

• The curtain walls have horizontal overhangs and verticalfins, screenshots of what I have already attached above

Characteristics:

• Please find above!

Level views and 3D view:

For 2 Units

Please share your design showing the features of the proposed building envelope, including the locations and characteristics of:

• the wall and roof surfaces
• the openings/glazed surfaces
• windows and/or curtain walls
• doors
• skylights
• any shading or sun control features

Wall and Roof Surfaces:

For 3 Units

• Use your Building Element Model to create an Energy Model.
• Submit this Energy Model to the Insight analysis tool to explore how the choices and specifications you’ve made in your Building Element Model affect the predicted energy performance.
• Be sure to set the Operating Schedule factor tile to use the BIM value.
• Narrow the range of values being considered for the building envelope-related factor tiles to focus on the BIM Model value or better.
• Explore how other factors (such as Photovoltaic panel options) can further improve your building performance — by using renewable energy to complement your energy saving envelope features.
• Share the results of your Insight optimization:
• Include an image of the EUI meter and range indicator after you’ve made your adjustments to show what your current assumptions predict and how much potential there is for additional improvements.
• List the key Factor Tile settings that are driving these results.

For 4 Units

• Use one of the Daylight Analysis methods demonstrated to assess the daylighting levels available with your proposed building envelope design:
• Choose one of these methods:
• Option 1: Use the Revit Lighting Analysis extension to produce an Illuminance Map of one of the levels of your proposed design.
• Be sure to watch the videos for tips about what you’ll needed to include in your building model for the lighting analysis to produce valid results. For example, you’ll need to place Rooms and Floors.
• To analyze your model for 0 credits, be sure to choose a single level at a time and use 72 inch grid as the analysis resolution.

• Paste an image of the resulting Illuminance Map.
• Option 2: Use the Revit Cloud Render tool to produce Illuminance Renderings of three key areas in your building model.
• Place cameras in your model to create 3D camera views to be rendered.
• Use the View > Cloud Render tool to generate Illuminance Renderings for these camera views.
• Paste images of the Illuminance Renderings into your Design Journal posting.
