Mitigation
Implementation of measures designed to reduce the undesirable effects of a proposed action on the environment
Mitigation
3 Categories of Mitigation
Prevention & Control
Compensatory
Remediation
To fully or partially prevent an impact or risk by changing the means or techniques, changing the sites, or specifying operating practices
Purpose of Prevention & Control Measures
To offset the adverse impacts in one area by improvements in another area
Aim of Compensation Measures
To repair or restore the environment after damage is done
Goal of Remediation Measures
produced from vegetable oils and animal fats
Biodiesel
made from plant materials
Ethanol
is a by-product of natural gas processing and crude oil refining
Propane
is maid up mainly of methane
Compressed Natural Gas (CNG
fuel only emits water vapor
Hydrogen
Other Sources of Renewable Energy
Sunlight, Wind
6 Sustainable Building Design
Optimized site potential
Optimized energy use
Protection and conservation of water
Optimized building space and material
Enhanced indoor environmental quality (IEQ)
Optimized operational and maintenance practices
Proper site selection, orientation, and landscaping; and consideration of the reuse or rehabilitation of existing buildings and future expansion
Optimized site potential
To reduce energy load, increase efficiency and maximize the use of renewable energy resources to significantly reduce dependence on fossil fuel-derived energy
Optimized energy use
To use water efficiently, reduce reuse or recycle water for on-site use
Protection and conservation of water
The integrated and intelligent use of materials to minimize their value, prevent upstream pollution, and conserve resources
Optimized building space and material use
Impact occupants health, comfort and productivity
Enhanced indoor environmental quality (IEQ)
Specifying materials and systems that simplify and reduce maintenance requirements; require less water, energy, and toxic chemical s and cleaners to maintain; and are cost-effective and reduce life- cycle costs.
Optimized operational and maintenance practices
is unhealthy for both humans and animal alike because it affects our body clock and natural processes such as sleeping
Excessive lights
in some cities should be hundreds and thousands of time higher than natural night-time light
Light levels
should be oriented to minimize spillover and glare.
Buildings
should be avoided, as well as the use of glass and other reflective materials. Moreover, plants could be used to block the light
External lighting
should not exceed 30 dBA for sound sleep. However, in places close to airports, the noise from aircraft taking off and landing exceeds 100 dBA
Ambient sound levels
one solution is to use rubberized asphalt pavement. The mix also extends the life of the concrete road base
Road noise
produces a sound field that is the mirror image of the offending ambient sound, effectively cancelling the latter.
Active noise control
is very important, two zones adjacent to each other must have compatible uses
Zoning
for non-voice sensitive use between two zones can reduce noise impacts to the residents
Buffer areas
the proposed structure that may be encounter or produce noise
