Every LEED measure begins with a statement of intent. This is important because some projects meet the letter of the measure but not the spirit. For example, one can reduce water demand in irrigation by 45% (WE2.3) by paving over the lawn,
but that doesn’t meet the objective to “minimize outdoor demand for water through water-efficient irrigation.” A better way to lessen irrigation through landscape design that also meets the intent of the measure is xeriscaping.
The intent of Innovation and Design Process 1 is to maximize opportunities for integrated, cost-effective adoption of green design and construction strategies.
This begins with a prerequisite, measure 1.1 Preliminary Rating.
As early as practical, conduct a preliminary LEED for Homes meeting, with the participation of the Provider and key members of the project team. As part of the meeting, create an action plan that identifies the following:
The targeted LEED award level (Certified, Silver, Gold, or Platinum).
The LEED for Homes credits that have been selected to meet the targeted award level.
The party accountable for meeting the LEED for Homes requirements for each selected credit.
Those are pretty self-explanatory. And pretty easy to meet for this project: I’ve targeted Platinum, the credits I will use to meet that level have been chosen and will continue to be documented in this series, and I am the accountable party for all requirements.
So we move on to the credits.
1.2 Integrated Project Team (1 point).
Assemble and involve a project team to meet the three criteria below:
a) Include team members, in addition to the builder and Green Rater, whose capabilities include at least three of the following skill sets:
- architecture or residential building design;
- mechanical or energy engineering;
- building science or performance testing;
- green building or sustainable design; and
- civil engineering, landscape architecture, habitat restoration, or land-use planning.
b) Actively involve all team members referenced above in at least three of the following phases of the home design and construction process:
- conceptual or schematic design;
- LEED planning;
- preliminary design;
- energy and envelope systems analysis or design;
- design development;
- final design, working drawings or specifications; and
c) Conduct meetings with the project team at least monthly to review project status, introduce new team members to project goals, discuss problems encountered, formulate solutions, review responsibilities and identify next steps.
Keeping in mind the intent to maximize opportunities for integrated, cost-effective adoption of green design and construction strategies, I’m awarding this point to my project. There aren’t any other team members with whom I conduct meetings, but I’ve planned it with careful thought to all aspects of green building (electrical, plumbing, materials, design, etc.), and I can safely say that everyone involved in construction (still just me) is on board with my plans.
1.3 Professional Credentialed with Respect to LEED for Homes (1 point).
At least one principal member of the project team shall be a professional who is credentialed with respect to LEED for Homes as determined by the U.S. Green Building Council.
I can’t get this one; my credential is in Building Design and Construction, which is focused on commercial projects, schools, hospitals, and other non-residential projects.
1.4 Design Charrette (1 point).
No later than the design development phase and preferably during schematic design, conduct at least one full-day integrated design workshop with the project team defined in ID 1.2. Use the workshop to integrate green strategies across all aspects of the building design, drawing on the expertise of all participants.
This one I’m awarding because I have spent far longer than one day integrating green strategies, and I’ve drawn on the expertise of many others, both through in-person discussions and internet research, to do so.
1.5 Building Orientation for Solar Design (1 point).
Design the home such that all of the following requirements are met:
a) The glazing area on the north- and south-facing walls of the building is at least 50% greater than the sum of the glazing area on the east- and west- facing walls.
b) The east-west axis of the building is within 15 degrees of due east-west.
c) The roof has a minimum of 450 square feet of south-facing area that is oriented appropriately for solar applications.
d) At least 90% of the glazing on the south-facing wall is completely shaded (using shading, overhangs, etc.) at noon on June 21 and unshaded at noon on December 21.
This one is a bit of a stretch because the bus moves, but a) after replacing some the windows with steel panels, the long sides of the bus have twice as much window area as the short sides of the bus; b) we can park it in whatever orientation is optimal; c) our whole floor plan is only 200 square feet, but I have 150 square feet of roof space reserved for adjustable solar panels; and d) we have retractable awnings.
If I were submitting this project formally, I would file a Credit Interpretation Request on this one. If a project team identifies an alternative way of achieving the intent of an existing LEED credit, the team can request permission to meet the intent of the credit using an approach that is different from the stated requirements. I believe they would grant the credit under these circumstances, so I am awarding it.
