Leed or sustainable design
Sustainable design: Economics, aesthetics, environments, mechanical systems
Natural step: Organized 1996, preservation of ecosphere & bio sphere (-5 within each to +5 miles above surface of earth).
Natural step principles
-Zone of earth that supports human life is highly fragile eco system last 100 years has affected the earth “wrong” biosphere affecting human is relatively stable & resistant 5 mile in/ out
–Vast majority of technological building environment is inefficient. innovation has improved, but not there
-Toxic substance affect large areas beyond time & space are above “great lakes” is toxic with DDT many years after it has been banned, jet streams bring toxicity elements & pesticides in other continents
-Recycling is only beginning: More buildings to be recyclable & biodegradable
LEED: Cost of design for Engineers & Architects increase
Vandalism: Impact is to use impact resistance materials
In housing projects
-Exterior paths & entrance doors are visible
-Surveillance, well lighted, avoid cursed paths
-Durable & vandal & tamper proof of elements
Planning phasing sustainable projects:
-Use native landscaping- functional, aesthetic..
-Sun orientation (neighbors…) topographic relief
-Scale of other buildings
-Location of project with respect to public transportation
Elements in sustainable design:
-Solar shading devices
-Urban heat island effect
-Fenestration & glazing
Sustainable goals: Use less, recycle, do not deplete natural resources, do not buy from long distance, least amount of demolition, keep existing
LEED indoor air quality: Sick building syndrome: Poor indoor Air Quality based on indoor tobacco smoking, inadequate ventilation, off gassing of fabrics and coatings
Leed substitution by Architects: Architectural supervision: Product substitution to insure original design standards are met
Leed: Requires Architect, Wetland Engineer, Energy Engineer Commissioners, Landscape Architect, Energy Model Engineers
