Design Charrette–Planning

There is a LEED point for having a kick0ff planning meeting with the LEED Project team. LEED calls this meeting a Design Charrette which is a french term for taking a cart around to get input on an architectural design. So this cart is leaving the barn on April 23rd.

The charrette is a full day event. We are going to start at the offices of Energy Logic in Denver. The office is conveniently over a coffee shop so breakfast will be near at hand. Then we will delve into the project before us. Here is the agenda for our planning day for this LEED for Homes gut remodel.

Morning Agenda: 8 a.m. to 12 p.m.  Convene at Energy Logic Denver Office. 3606 W 50th Ave. Denver, CO 80212

Introduction: (Ellen-15 minutes)   A design charrette—a focused and collaborative brainstorming session held at the beginning of a project—encourages an exchange of ideas and information and allows truly integrated design solutions to take form.

1. Integrated Project Design   Platinum requires 94 points for 2213 sq. ft. 3 bedroom home

Introduction of the design team:

  • James Plagman: architecture or residential design
  • Shane Gring: LEED AP and green building or sustainable design
  • Annette Garrigues: landscape architecture, habitat restoration or land use planning
  • Ellen Dibble: Owner builder

Team will be actively involved in at least 3 phases of construction/design

  • Phase 1. LEED Planning
  • Phase 2: Design Development/Energy Modeling
  • Phase 3: Final Design/Implementation/Construction
  • LEED AP on Team: Shane Gring

1. Building slideshow (Ellen–15 minutes)

  • Building orientation East West axis—window ratios—south facing 450 sq. ft.
