2 Presentation Goals: Understand the general nature of the green certification programs recognized by IHDA Understand how a project obtains certification (process, players, potential costs) Understand which certification program may be a good option for a particular type of project

3 Programs recognized by IHDA as part of the Green Initiatives scoring item in the 2012 QAP: Enterprise Green Communities USGBC LEED ICC National Green Building Standard Certification (Emerald Level)

4 Green certification programs have common categories: along with both mandatory & optional pointscoring items in the categories

5 Green certification programs require third party: analysis of performance field inspection field testing The result is a verifiable measurement of sustainability for the project.

6 Green certification costs: third party verification costs design and construction costs (becoming less of a factor due to IHDA baseline requirements and 2012 IECC adoption by IL) registration and certification fees

7 Project Case Studies: 1. Rural location, greenfield site, new construction, 1-2 story, single family homes, 42 dwelling units

8 Project Case Studies: 2. Urban location, new construction, 4-story, multi-family, 60 dwelling units

9 Project Case Studies: 3. Urban location, gut rehabilitation, 3 story, multi-family, 40 dwelling units

35 LEED provides accountability to funding sources

36 Point Distribution by Credit Category Post-occupancy monitoring is rewarded 17 prerequisites + Points

37 Efficient Home Size = Free Points Project Specific: 3 bedrooms 1900 SF 45 pts 60 pts 75 pts 90 pts 1200 SF 35 pts 50 pts 65 pts 80 pts 2500 SF 52 pts 67 pts 82 pts 97 pts

38 Roles and Responsibilities Who Does What

39 LEED-H requires Energy Rater (like a CxA)

40 LEED Home Savings Across Certification Levels Data from 144 LEED homes Certified in Midwest Platinum Gold Silver Certified Energy Savings 46% 42% 24% 24% Conventional home monthly utilities LEED-certified home monthly utilities $345 $193 $91 $293 $189 $107 $70 $198 Monthly Savings $156 $86 $21 $95 Conventional home Annual utilities LEED-certified home Annual utilities $4,135 $2,310 $1,092 $3,520 $2,266 $1,284 $836 $2,381 Annual Savings $1,156 $1,026 $256 $1,139

41 More units = economies of scale LEED for Homes Green Rater (Provider and USGBC)

42 Rural Case 1: 42 single family homes Prerequisite Flags: Site protections, HVAC sizing, ducted returns, no carpet near doors Project team experience big factor Q: Have you ever done a blower door test? Q: Have you taken an IECC 2012 update course? Credit sites < ½ mile to services, above floodplain. Scored on worst-case tested home Can match phases Projected Cost: $750 $1000 per unit Lexington Farms, Jerseyville, IL Anticipated LEED Gold

43 Urban New Case 2 4 stories,60 units 4-story = commercial construction in Homes ASHRAE instead of HERS score Green rater replaces CxA ASHRAE 62.1 and 62.2 Mech. ventilation required Kit and bath exhaust Mixed-use allowed if < 50% sf Sampling can be used to test fraction of units Builder / GC experience critical! Cost: $600 - $1000 per unit Melrose Commons, Bronx, NY Anticipated LEED Platinum

44 Project Case 3: Urban Gut Rehab (3 stories, 40 units) Location, Location, Location! Prerequisite Flags: For LEED, must be gut rehab to studs (no moderate rehab like GC), Must add bath and kit exhaust, mechanical ventilation IECC requirements help Energy requirements Homeowner manual / training for occupants Multi-bldg data tracking Usgbc.wegowise.com Sampling eligible Greater % of units tested Cost: $800 - $1200 /unit Evans/Langley Apartments, Chicago, IL

45 Step-by-Step Process Choose Green Rater / Provider Tip: Optional up-front costs (e.g. charrette meeting) will often mitigate later problems

47 Bill Styczynski Styczynski Walker & Associates NGBS / ICC-700 Test

48 National Green Building Program Based on the ICC/NAHB National Green Building Standard. The NAHB National Green Building Program is a points based certification process with four levels of certification Bronze, Silver, Gold, and Emerald. Emerald Level is required for 2012 IHDA QAP

49 NGBS Certification Process Create a Designers Report Use the Green Scoring Tool available at NAHBgreen.org Hire an Accredited Verifier Third party verifiers are accredited by the NAHB Research Center consult with the verifier early in the process Schedule a Rough Inspection Before drywall but after complete installation of insulation Complete the Application Agreement must be completed prior to certification Home Certification Fees Non-NAHB Member $500 per building + $20 per unit/multi-family NAHB Member $200 per building + $20 per unit/multi-family Verifier & other third party fees will vary Schedule a Final inspection Inspection upon completion all work must be complete and in place in order to award points

50 NGBS Energy Requirements To achieve the Emerald level You must comply with Section 701 Minimum Energy Efficiency Requirements. You must use the Performance Path (Section 702). You must claim a minimum of 30 points from Section 702 & at least 2 practices from Section 704 (Additional Practices). You may not use the Prescriptive Path. Energy efficiency features are implemented to achieve an energy cost performance that exceeds the ICC 2006 IECC by 60%

51 Single Family Homes Energy performance level 60%> than 2006 IECC The challenge will be lot design and development criteria, especially a Greenfield site on former farmland without local mass transportation and community resources. Consideration to density, landscaping, project management and storm water management Other aspects of green building are achievable, possibly needing to look at life cycle analysis for product selection for instance.

52 Urban New construction Multi-family Energy performance level 60%> than 2006 IECC Points are totaled based on the building common areas and each typical unit. Practices shall be implemented in all units, as applicable Lowest points total for any of the various units will determine the building certification level.

53 Urban Gut Rehab Multi-family May be scored using one of two alternate methods if originally permitted before 1980 Green Building Path The practices in this path are generally the same as the practices for new construction but some of the practices are modified by Renovation Notes. Green Path Remodel Emerald Level - Pre 1980 Units This path has only 3 required elements: Reduce energy consumption by at least 50% Reduce water consumption by at least 50% Meet all mandatory items for Green Path Remodel - IAQ
