Jysk Trykprøvning A/S

What Jysk Trykprøvning A/S does

Jysk Trykprøvning A/S is a Danish building inspection and certification firm headquartered in Knebel, Midtjylland, founded in 2008 and operating nationwide. The company specializes in pressure testing (blowerdoor testing), energy labeling, energy frame calculations, heat loss calculations, acoustic measurements, building thermography, and energy advisory — a coordinated portfolio of services required for Danish building regulation compliance and completion certification (færdigmelding). It serves both private homeowners and professional construction clients, including contractors, developers, and public-sector projects (hospitals, military installations, schools, retail, offices), with a notable client roster spanning IKEA Aarhus, the Danish Ministry of Defence, Aalborg University Hospital, VIA University College, and Forsvarsministeriet.

The underlying technology is a mix of physical measurement instrumentation — Minneapolis Blowerdoor equipment for airtightness verification at 50 Pa differential pressure per DS/EN ISO 9972 / DS/EN 13829, Brüel & Kjær acoustic sensors, and thermal imaging cameras — combined with computerised pressure testing analysis and Odeon room acoustics simulation software. The firm holds ISO 9001 certification for both pressure testing and energy labeling (issued by Byggeriets Kvalitetskontrol), and operates with a tightly specialised team of approximately 5 staff under director Vivi Gilsager, who concurrently serves as technical auditor for the Danish Energy Agency (Energistyrelsen) and chairman of the Klimaskærm building envelope trade association.

Commercially, Jysk Trykprøvning operates a project-based professional services model with publicly listed unit pricing for small buildings (60-300 m² packages from DKK 4,375 to 11,625 incl. VAT) and quote-based pricing for larger projects (300-100,000 m²). Distribution is direct — phone, email, and website contact — with no intermediaries or resellers, and identical pricing across all Danish regions. Go-to-market relies on professional network referrals, the director's regulatory and industry leadership roles, and an additional community-led motion through paid training courses for construction firms and vocational schools (DKK 1,500/hour).

Products and services

• Trykprøvning (Pressure Testing / Blower Door Test) Mandatory air tightness testing of building envelopes using Blowerdoor equipment at 50 Pa differential pressure to verify compliance with Danish building regulations under DS/EN 13829 (permits pre-July 2016) and DS/EN ISO 9972:2015 (permits post-July 2016). Serves construction companies and private homeowners needing completion certification.
• Energimærkning (Energy Labeling) Mandatory energy certification for single-family houses, multi-family buildings, and commercial properties, calculating energy consumption and assigning buildings an energy classification. Performed by approved energy consultants per SBI 213 and the energy consultants handbook; used for property transactions and completion certification.
• Energirammeberegning (Energy Frame Calculation) Calculation of a building's total annual energy consumption in kWh per m² per year for new buildings of all sizes, including building components, windows, linear thermal bridges, ventilation, heating, domestic hot water, renewable energy, and lighting for commercial buildings. Includes third-party control options.
• Lydmåling (Acoustic / Sound Measurement) Building acoustics testing using Brüel & Kjær equipment, covering airborne sound insulation (R'w, R'w+C50-3150), impact sound (L'n,w, L'n,w+CI,50-2500), reverberation time (T), indoor traffic noise (Lden), and noise from technical installations (LAeq). Supports compliance with Danish acoustic regulations for residential and commercial buildings.
• Bygningstermografi (Building Thermography) Thermal imaging inspection to identify cold bridges, air leaks, and insulation deficiencies in building envelopes using thermography cameras, used in combination with pressure testing to distinguish genuine cold bridges from air leakage.
• Fortrykprøvning (Pre-Pressure Testing) Early-stage pressure testing performed before the final climate envelope is completed while the vapor barrier is still visible, allowing identification and correction of leaks before final pressure testing and certification.
• Varmetabsberegning (Heat Loss Calculation) Calculation for building additions or renovations to demonstrate that overall energy consumption is not increased by the modification, supporting regulatory compliance for extensions and renovations.
• Energivejledning (Energy Guidance / Advisory) Professional energy advisory services for private individuals, craftsmen, and consultants on energy renovation and energy assessment, including third-party quality control (3-partskontrol) for energy frame calculations.
• Kursus / Undervisning (Training Courses) Training courses for construction firms, tradespeople, and vocational schools on pressure testing, building airtightness, and vapor barrier installation, typically 2-3 hours with hands-on Blowerdoor demonstrations, priced at DKK 1,500 per hour ex. VAT.
