WALL :

• for the walls, I wanted to maintain the “monolithic” and institutional aesthetic, while utilizing curtain walls to give the illusion of lightness/the glass supporting the structure (will add columns in the future). I created my own wall type where I edited the CMU with insulation to have precast concrete instead. The walls ended up being pretty thick (over 2 feet). It could definitely work as structural walls. I will still have columns and structural framing on the interior, I am thinking mass timber / glulam beams and columns.

WINDOW :

• While I wanted to minimize window to wall ratio for the sake of sustainability and the HVAC load, I also wanted to ensure good daylighting and views. I will need to mess around with fins and louvers and shading to optimize the experience of my building. I wanted to bring light into the stair cores because the other “core” features of the buildings like bathrooms and mechanical rooms don’t usually require windows. Could be interesting to add windows with a very low VLT (potentially glass block) placed high to bring some natural light into spaces like bathrooms. I was also playing around with different degrees of openness/ opacity/privacy with the thin floor to ceiling height windows that will still let good light in while minimizing glare and unwanted heat gain. I kept the WWR on the east and west sides pretty low (~5-15%), and the WWR on the north and south sides pretty high (70-90%).
• I added a skylight to the top of the roof (may opt for a sloped roof instead). It lets a good amount of light into the atrium then to the rest of the spaces.
• Basic windows:

• Skylight:

FLOOR :

This might be adjusted, instead of metal deck it could be on wooden beams. I would still keep it lightweight concrete. again, to go with the monolithic/institutional feel for the building.

ROOF :

Also kept the roof fairly simple with insulation on metal deck, but also want to further explore wood framed roof/mass timber roofs. Need to play around with looking on online resources a bit more.

INSIGHT ANALYSIS OVERALL OBSERVATIONS:

• By playing around with the insight settings, I was able to lower my building’s EUI from 94.7 to 11.1 kBTU/ft2/yr which seems ridiculously low. I kept the operating schedule at the BIM settings, but found the most impactful values ended up being plug and lighting load efficiency, HVAC systems (terminal heat pump) and implementing high efficiency PV on a majority of the surface. Adding things I currently don’t have a lot in my model like shading can help reduce EUI by 2-5 kBTU/ft2/yr, so I will go back and make those additions. The south side of the building is already naturally shaded by itself / its overhangs.

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

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.
