LCA MODULE 2 3 Building Industry Reporting and Design for Sustainability (BIRDS v1) For environmental and economic analysis of new commercial buildings Operating energy Environmental performance of materials, construction, and use Life-cycle cost Online-based tool Produced by NIST in the US Simple input in three steps (output options in fourth step) Select building Select comparisons
Select environmental preferences Available at: birdscom.nist.gov Logo: birdscom.nist.gov 10/2015 LCA MODULE 2 4 BIRDS (Step 1) Building types include
Apartment Dormitory Hotel Office Restaurant Retail Store High School For each various number of floors available Click 10/2015 to open detailed information as shown
LCA MODULE 2 5 Baselines In Steps 2 and 3 baselines must be selected including Building location In Step 4, will choose which to make Building energy standard comparisons along Study period Only one can be used as the basis of Impact category weighting scheme comparison at a time All others will take value of base case
10/2015 LCA MODULE 2 6 BIRDS (Step 2) Choose baseline value State City ASHRAE Edition Time period (1-40 years)
ASHRAE 189.1-2009 Can choose alternatives to compare to Same selections as baseline ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings Prescriptive or performance based Often used as municipal/state standard or part of standards 10/2015 LCA MODULE 2 7
BIRDS (Step 3) 12 impact categories Choose weighting scheme BEES Stakeholder Panel EPA Advisory Board Carbon Footprint Only Equal Weights Custom Weights This baseline and alternatives is
not referring to baseline/ alternatives chosen in Step 2 Just alternative weighting schemes to apply to all cases Click by Pre-defined Weights to see how schemes are developed 10/2015 LCA MODULE 2 8 BIRDS (Step 3) 10/2015
LCA MODULE 2 9 BIRDS (Step 4) Choose type of results Life-cycle cost Operating energy Environmental impact 10/2015 Choose one dimension as comparison basis Building location Building energy standard Study period
Impact category weighting scheme LCA MODULE 2 Indictor unit kg eq substance kg eq substance/ft2 change in each 10 BIRDS Results Study Period Global Warming kg CO2-eq Shows total impact (not yearly) Divide by study period for yearly impact
Shows only selected unit on chart All units in table below 10/2015 LCA MODULE 2 11 BIRDS Results Locations All (Weighted) Env. Impact Score 10/2015 LCA MODULE 2
12 BIRDS Results Energy Edition Smog kg O3-eq/ft2 10/2015 LCA MODULE 2 13 Building for Environmental and Economic Sustainability (BEES) Predecessor to BIRDS
For environmental and economic analysis of building products Online-based tool Link to BEES online Produced by NIST in the US Analyze individual building products (rather than whole building) Nearly 200 products included Concrete, roofing, insulation, water distribution piping, cleaning materials, paving, more Simple to use Most data and processes set, just choose weighting scheme, product(s) of interest, and transport distance 10/2015 LCA MODULE 2
16 Performance weights BEES can output a score in addition to impact category indicators This weights importance of environment and economics in scores For environmental analysis alone, enter 100 Discount rate deals with time value of money (does not affect environmental) 1 dollar invested today might be worth 2 dollars in 10 years 10/2015 LCA MODULE 2
17 Element Selection Major group elements include Building Maintenance
Building Repair & Remodeling Building Sitework Domestic Water Distribution Equipment & Furnishings Interiors Sanitary Waste Services Shell Substructure All products in one list 10/2015 LCA MODULE 2 18
Product Selection Inventory results by life cycle stage Only appears after clicking compute 10/2015 LCA MODULE 2 19 Output Type Selection 10/2015
LCA MODULE 2 20 BEES Output By life cycle stage By environmental flow 10/2015 LCA MODULE 2 21 Thank you for completing Module 2!
