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:

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 weatherization/energy assessments and audits of single-family detached homes and multi-family properties to determine the number and type of weatherization measures eligible for installation for the Austin Energy and Travis County Weatherization Program. IBTS performed a series of diagnostic tests including a blower door test, pressure pan measurements, duct blaster testing and combustion testing of all gas appliances for carbon monoxide emissions. Additionally, IBTS diagnosed the HVAC system, attic and wall insulation, windows, doors, refrigerators, and similar systems and equipment to determine where energy savings could be implemented to achieve the greatest savings to investment.
