Design Journal Entry - Module 4

Journal Entry For
Module 4 - Conceptual Design - Building Context & Passive Design

Your Design Journal entries for this module should highlight:

  • the design alternatives that you modeled and tested
  • the results of the analyses and how they influenced your thinking about how to move forward

Use text , images, web links, movies... Whatever media works best to express your ideas!

For 2 or 3 units

  • Create and share a Psychometric chart for your project location.

The site is located along a hiking trail at the foot of Dish Hill at Stanford, CA, where Climate Zone is 4. The Psychometric chart of this location is shown as below. Here is described as Heating-zone area, where basically heating or cooling is required based on its climate condition.

Site Location - Stanford Dish

Construction site is alongside the Junipero Serra Fwy, and also neaby the Dish Hill hiking route.

This hiking course is very good location for Stanford students, this hiking trail can be walked around in 40 to 50 minutes, but there is only one spot on the route to refill water bottles. Also, for runners, there is no place to hydrate. The surrounding trees are also an area more exposed to wildfire risk than the trees within Stamford. The trees are considered to be planted with shrubs, which are more drought tolerant.

Big Idea

Based on the above context, I want to connect this building to the hiking route and attract hiker to interact with each other and let them experience the nature of this hill much closer.

  • Test 2 different alternative conceptual building forms using:
    • Insight analysis to predict the energy performance each of the forms

      • Option 1:

      Energy consumption of Option 1 is at first higher than that of ASHRAE 90.1 criteria. Window shade, Glass type, Roof type, Infiltlation, and PV are applied for reduction energy intensity leading to less than ASHRAE 90.1, the cost is almost $15.4/m2/yr.

      Option 2

      The building shape of Option 2 is not square, but double L shape design, which energy cost is less than that of Option 1, even though the foot print is almost same. the reason is Option2 volume is less than Option1. Therefore, it is necessary to minimize the heating/cooling space within the building. Based on the analysis below, the south wall/opening, Roof type, PV coverage have the biggest impacts on the Energy Intensity. The building orientation did not have a major effect, so the current orientation will be kept.

    • Solar insolation analysis to predict the solar radiation on the surfaces of the forms

  • Post images of the design alternatives that you modeled and the results of the analyses
  • Explain your reasoning and the tradeoffs that influenced your decision about which design option to move forward with

For 4 units

  • Given the conceptual form that you’ll be carrying forward, use Insight to determine the most important factors and their values that could deliver these performance thresholds:
    • Architecture 2030
    • Net Zero (if possible) or the best performance reasonably achievable
