The blog was designated to be a single group member’s responsibility each week, and the website was created (https://du2019-grp071-02.blogspot.com/). The team agreed on the location and style of house.
Day|4 April 2019
During the lab period, introduction to research on the building design was completed. The team finalized major topics in the proposal of the project. The main goals were quantified through PassiveHaus. A general schedule was made for the next ten weeks and will be followed as close as possible for a successful completion of the building. Each team member was given a specific topic in the design to focus on, and research will be conducted to facilitate the design process. The proposal will be worked on thoroughly in week 2.

Week 3
Day | 16 April 2019
Tuesday's lecture focused entirely on learning how to create calculations pertaining to efficiency and the building envelope. Based off of this information, the team worked to create a more set building geometry. Creating the architectural layout for the structure allows us to be able to have a set square footage which is necessary for the energy calculations.
Another aspect that was incorporated into the lecture and discussion today was the usage of materials. Using different materials will impact the efficiency of the building.

Day|18 April 2019
Today entailed the first real energy calculations. Using the prospected square footage of the building and Passive House energy standards, a target total heat energy was calculated. In addition, a K total value was found to give a estimated energy usage for the year.

To assure that our design is actually efficient, we began to look at windows and overhangs. Roof angle calculations were completed to determine the size of an overhang as well as the ceiling height of the attic.

Calculations pertaining to overall energy and windows were done on a spread sheet linked below:

Week 4
Day|23 April 2019
Tuesday's lecture focused on solar energy design. The team was tasked in researching irradiation data (average monthly), optimal tilt/orientation of solar array, battery storage devices, selling electricity to utility companies, degradation over time of solar panels, and the influence of environmental conditions on solar energy efficiency.Following the lecture, the team continued to research the materials to be used in the building's envelope and began to finalize the envelope design for Thursday's lab period. A basic structure is shown in the image below. The different materials and their relevant information can be found in the same spreadsheet linked in Week 3.

The team also started the research tasks assigned in the lecture by gathering types of solar panels and their efficiency and beginning to design the solar panel orientation.
Day|25 April 2019
During today's lab period, the team continued to finalize the envelope design which is necessary for quantifying the solar panels to be installed on the building's roof. It was decided to install a geo-pump for the building's heater system and construct the windows with triple pane glass. The team also began calculating the heating energy requirements for the house, which are detailed in the spreadsheet as well.Day|29 April 2019
The team met outside of scheduled lab and lecture times to add the stud frame to the envelope design. It was decided to construct the frame from Tstud™ rather than pinewood. Tstud™ has extra insulation and a high R-value of 20. The image below presents the area calculations and basic structural details of the stud frame that were also used to recalculate the dimensions of the insulation in the envelope.

Week 5
Day|30 April 2019
Tuesday's lecture highlighted water loads, water reuse, and internal heat loads. For the water aspect of the design, the team was asked to determine the annual water usage of the design. Additionally, the team was tasked with implementing either a grey water or rainwater system to feature water reuse within the design. As for internal heat loads, the team was also assigned to document the internal gains of people, lights, and other equipment inside the house.
Tstud™ framing. Meanwhile, other members collected rainwater data for the site of the design as well as detailed the internal heat gains from the human occupants of the design. The envelope calculations, rainwater data, and internal load calculations are all documented in the spreadsheet linked in week 3.
Day|2 May 2019
During today's lab period, the team continued working on the calculations from the previous lecture period. The calculations resulted in a final K value calculated for both the windows and walls of the house, but the K value for the roof will still be determined. Additionally, the team began to search for appliances to get values for the design's electrical plug load, water usage, and heat gains. These appliances and other calculations are outlined in the spreadsheet.Week 6
Day|7 May 2019
As the final draft report was introduced, the team used the requirements of the final report as a progress check towards the completion of the project. The team planned the use of research as references in the report of sustainable design and the comparison to the team's design. Methods of analyzing building envelope and energy use so far were consolidated to be explained in the report. The team met together to plan for technical writing and how to organize and discuss the work conducted for the past few weeks.
Calculations for the roof and internal heat gains were started, with hopes to complete them for use in the final report draft on Thursday. The solar energy analysis was finalized, with the most efficient panels chosen and quantified based on roof area.
The lecture for this week introduced the use of eQuest as a tool for energy simulation. A demonstration was carried out as a class using the software, during which the group familiarized itself with the basic features of the program and the results of the program's building energy analysis. The recitation section for this week was used as a work period during which significant progress was made with the drafting of the assigned laboratory report. The areas of concentration for this session involved completing the technical activities and results sections of the report and editing our document to adhere to the page requirement guidelines outlined by the course instructor.

Day|9 May 2019
This work period was dedicated to finishing calculations and results for use in the final report. The Biowall research was initiated, with effects on internal gains being analyzed. A final Ktot value including the roof was finalized. The number and type of lights were chosen, so the internal gains were finalized for the three main components: people, appliances, and lights. The location of windows were designed as the number of windows were predetermined. The team started working on the technical activities of the draft, which each member dedicated to their respective system in the design. A discussion of the 3D rendering and design took place, in which all components and system designs came together to portray the building as a whole.Week 7
Day|14 May 2019
Day|15 May 2019
The lab report was successfully submitted.
Day|16 May 2019
The following tasks were undertaken during this work period:- 2D rendering of building architecture (including solar panel layout and envelope components) using Revit modeling software
- Learning and calculation of parameters that indicate biowall efficiency and effectiveness
- Redesign of water filtration system to accomodate standard filtration techniques
- Energy use simulation using eQuest software
Week 8
Day|21 May 2019
This week's lecture introduced and set the standards for the projects final deliverable. Upon conclusion of the project each group is required to create an academic poster that will presented and possibly displayed in the College of Engineering poster contest. In class, poster guidelines as well as recommendations were reviewed to create an applicable poster. Recitation time this week was used to start drafting the potential poster. Drafting was done in Microsoft PowerPoint. The group decided to break each system component of the project into a designated section of the poster. Additionally tables, figures, and renderings were collected to add to the final deliverable.
