What is the Building for Economic and Environmental Sustainability (BEES) model?
Developed by The National Institute of Standards and Technology (NIST), this approach evaluates the life cycle costs and environmental impacts of building materials in 10 areas of concern.
What is ASTM?
The American Society for Testing and Materials.
Also developed an approach for evaluating the life cycle costs of building materials (Standard Guide for Environmental Life Cycle Assessment of Building Materials/Products, E 1991–98). This is a broad-based approach that includes consideration of embodied energy, raw materials acquisition, and environmental impacts.
What are some typical effects on Operating Costs brought by Green Desingn?
- Electric savings 45-55% (payback period of 7-9 years, more common less than 2 years)
- As much as 90% water usee reduction (50% more common)
- Lifecycle savings of 10x typical ($100,000 upfront investment in green building = 1 mil life cycle savings)
What is the minimum slope for grassy swales and drainage ways? Why?
1% to prevent standing water and muddy conditions
What is the maximum slope for walkways?
5% (2% cross-slope) anything steeper becomes a ramp or stair.
What is the correct slope for parking areas or large entrance plazas?
Minimum 1% to maximum 5%
Paved areas adjacent to buildings should have what slope?
at least 2% away from the structure
If planted areas are adjacent to a building, how should they be sloped?
The first 10 feet should be sloped away from the structure to assure that there’s no standing water next to the basement/foundation walls.
When can you build in the 100-year flood plain?
Almost never! Unless approved by AHJ. Even then, the mechanical & electrical rooms must be 5’ above the level of the 100-year flood plain.
What are the slope numbers for turfed areas?
- Minimum 1% slope (2% desireable)
- Steeper than 2:1 not acceptable
- Steep slopes require plants or constructed to control erosion
What structural system should be chosen if you want a simple floor and roof framing to be fabricated on-site?
- Sitecast concrete
- Light Gague Steel
- Masonry with concrete slab and wood floor framing
What structural system should you choose if you would like to avoid beams and joists in the floor and roof of an irregular column grid, what structural system should you choose?
Sitecast concrete or metal space frame
What structural system for an exposed fire-resistant structure?
All concrete structure or Heavy Timber
What structural system for the thinnest floor system?
Prestressed Concrete Slabs
or
Sitecast Concrete (2-way flat plate)
or
Posttensioned (1-way) slab
What structural system for a long span? Given limited space for colums
any of:
- Heavy Wood Trusses
- Glulam Beams
- Steel Frame/Trusses
- Open Web Joists
- Concrete Waffle Slab
- Concrete T
