A BASIC INTRODUCTION TO LIFE CYCLE ASSESSMENT FOR BUILDINGS Definition and general methodology Life Cycle Assessment LCA is now a well-known and internationally recognised technique abundantly documented and framed by standards.

A branch of the green building movement lca. LCA is the investi-gation and valuation of the environmental economic and social impacts of a product or service. Both of these definitions mention life cycle assessment LCA. This tool that can be used is the LCA methodology through a software evaluation like BEES Building for Environmental and Economic Sustainability software.

Trusty MA1 Scot Horst2 1The ATHENA Sustainable Materials Institute1. In the US LCA is encouraged in the Green Globes rating system and included in the new American National Standard based on Green Globes ANSIGBI 01-2010. In the early years green builders were a small minority and their goals of reducing the environmental impact of buildings were considered unrealistic.

One can assess buildings to understand their environmental hot. The World Green Building Council its global network of Green Building Councils in 75 countries and their 32000 member companies will stand united in our efforts to fight climate change through green building in the wake of yesterdays announcement that the US will withdraw from the groundbreaking Paris Agreement. This also produced a much greater interest in alternatives approaches to housing and in this period the solar power movement is born which itself is the beginnings of the green building movement.

A life cycle assessment LCA is an evaluation of the relative greenness of building materials and products. Materials are assessed using green specifications that look at their Life Cycle Analysis LCA in terms of their embodied energy durability recycled content waste minimisation and their ability to be reused or recycled. Therefore the whole life cycle assessment LCA including the operation stage is necessary for green building assessments.

They are the sanctioning body for LEED the program with which points are awarded to various design applications within a building ultimately resulting in LEED certification for the building. In the context of green buildings LCA evaluates building materials over the course of their entire lives and takes into account a full range of environmental impacts. LCA removes the guesswork.

First of allin the common practice the energy consumption during the period of use is considered the main indicator of the environmental impactof buildings. Life Cycle Analysis LCA applied to buildings aims to assess the potential environmental of buildings over the complete life cycle from materials production to the end-of-life and management of waste disposal. LCA addresses the impact of a product through all of its life stages.

LCA is a great tool for finding high-impact hot spots in the building overall during early design and then exploring systems or assemblies that might reduce the anticipated impacts as details are filled in. Box 189 Merrickville Ontario Canada K0G 1N0. Nevertheless the method is rarely utilized for many reasons.

The United States Green Build Council USGBC is the foremost leader and educator within the world of green building today. LCA were initially developed for the analysis of simple products ie products with short periods of life and very specific functions. There is however another important piece to this puzzle.

USGBC The United States Green. It considers the entire value chain using the ISO 1404044 standard. Integrating LCA Tools in Green Building Rating Systems Wayne B.

Victor Olgyays work Design with Climate published in 1963 and Ralph Knowless book Form and Stability published in 1967 provided inspiration for the green building movement. By the 1980s many of these early highly insulated homes developed problems such as rotten wood inside walls mold sick building syndrome and fogged dual pane windows. It can also act as a blue print when cities and GBCs sit down together and start developing plans for green building policies incentives and regulation.

LCA is the cradle-to-grave quantification of potential environmental impacts of products or services. LCA is a method to assess environmental effects associated with all the stages of a products whole life cycle including its production use and disposal. That is making sure that a common language is used between our industry-led green building movement and political mandates such as the NUA.

The green building movement started in the 1970s as a way to reduce environmental destruction is changing the way buildings are constructed. Its not a seal of approval. Life Cycle Assessment LCA can be used successfully to make decisions in sustainable building design and construction.

Green building refers to practices that make buildings that are sustainable and resource-efficient throughout their life-cycles from siting to design construction operation maintenance renovation and destruction. It is also included as a pilot credit in LEED. Similarly dont take the use of whole-building LCA to mean that a building is green.
