For both new construction projects and existing buildings, IBTS can ensure proper building envelop design and maintenance to ensure better energy performance, HVAC loading, and indoor air quality, all while helping lower the total lifecycle cost of a building system.

IBTS’s green building and energy efficiency services include:

Independent Green Verification for the National Green Building Standard (NGBS): IBTS staff are trained and accredited to provide builders with independent third-party inspections and verifications required for NGBS certification. IBTS works closely with your construction team to ensure successful Green Certification by:

  • Identifying the appropriate and obtainable ICC700 Green Building Standard scoring points;
  • Coordinating inspections and verification steps to prevent delays and keep costs low;
  • Managing administrative and close-out processes, including submission of all images, forms, reports, signatures, score sheets, and related documents.

Large building air leakage testing: IBTS uses the Air Leakage Test Protocol, designed by the US Army Corps of Engineers for buildings that are new and undergoing major renovations.

Architectural Field Audits: As a third-party quality assurance (QA) auditor for Air Barrier Association of America (ABAA), IBTS conducts architectural field audits across 30 states, and reports on ABAA-certified projects ranging from $1 million to $100 million.

Energy Waste Diagnosis: IBTS uses infrared thermography inspections to measure heat loss/gain for residential and commercial structures. Once we know the areas of heat loss, we help implement specific solutions that improve energy efficiency, reduce air leaks, and improve electrical/mechanical safety.

Building Envelope Plan Review: IBTS provides pre-construction plan reviews and onsite field inspection services to building departments, building owners, architects, engineers, and general contractors. Our services include building and energy code compliance and overall building performance consulting.

Green Building Guidance: IBTS experts provide guidance on green building certifications, including: Leadership in Energy and Environmental Design (LEED)™, the ICC 700 National Green Building Standard, Energy Star™, and Energy Star Portfolio Manager ®.

Our Work in Action

IBTS performed comprehensive and electric reduction inspections of completed projects through the HPwES and EmPower Residential Single Family Field QA Program to determine the quality of installed measures in New York homes. IBTS performed over 1,700 field inspections and certified reviews of completed projects using the New York State Energy Research & Development Authority’s (NYSERDA’s) Quality Assurance Contractor Scoring System (QACSS) to track project status, report findings and observations, and offer potential ways NYSERDA could help mitigate these deficiencies in the future. IBTS’ inspections ensured program compliance in both the HPwES and EmPower New York Programs, and identified instances of noncompliance that led to the correction of issues to bring projects and builders into compliance.
