Environmental and health related criteria for buildings - ANEC

IBO - Environmental and Health related Criteria for Buildings
e) If soils in a sloped area (i.e., 25%, or 4:1 slope) are disturbed during construction, use
tiers, erosion blankets, compost blankets, filter socks and berms, or some comparable
approach to keep soil stabilized.”
The scheme LEED New Construcion & Major Renovations (2009) which is applicable for
high-rise residential buildings (> 3 storeys) specifies the SS prerequisite 1 (Construction
Activity Pollution Prevention) as follows:
“For achieving a SS Prerequisite 1 an erosion and sedimentation control plan during design
phase of the project must be created. The plan must conform to the erosion and
sedimentation requirements of the 2003 EPA Construction General Permit 81 or local
standards and codes, whichever is more stringent.
The plan must describe the measures implemented to accomplish the following objectives:
- To prevent loss of soil during construction by stormwater runoff and/or wind erosion,
including protecting topsoil by stockpiling for reuse.
- To prevent sedimentation of storm or receiving streams
- To prevent pollution of the air with dust and particulate matter
Consider employing strategies such as temporary and permanent seeding, mulching,
earthen dikes, silt fencing, sediment traps and sediment basins.“
Whereas the current version of LEED for Homes applicable for small residential buildings (<
4 storeys) does not consider any measures to attenuate dust from construction site activities
(the focus lies on erosion control and prospective planting), the more advanced (and
comprehensive) scheme of LEED-NC 2009 re-names issue SS1 as “Construction Activity
Pollution Prevention” and includes prevention measures of dust as well as particulate matter.
SS 1.2 Minimize Disturbed Area of Site (1 point)
To achieve one point, the following requirements have to be met depending on the lot’s size
and its previous status:
“Where the site is not previously developed 82 :
a) Develop a tree or plant preservation plan with “no-disturbance” zones clearly delineated
on drawings and on the lot (see Note 1 below).
b) Leave undisturbed at least 40% of the lot area, not including area that is legally protected
from disturbance, not including area under roof. Only softscapes can be counted toward this
credit; projects cannot receive credit for preserving preexisting hardscapes, such as
driveways.
OR
Where the site is previously developed:
c) Develop a tree or plant preservation plan with “no-disturbance” zones clearly delineated on
drawings and on the lot (see Note 1 below), and rehabilitate the undisturbed portion of the lot
by undoing any previous soil compaction, removing existing invasive plants, and meeting the
requirements of SS 2.2 (see Note 2, below).
81 The EPA’s (U.S. Environmental Protection Agency) construction general outlines the provisions necessary to
comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) programm.

82 Undeveloped sites with substantial amounts of garbage and/or invasive weeds should be treated as previously
disturbed sites.
