WindowMaster International A/S has won a contract to deliver a hybrid ventilation solution for the refurbishment of an unnamed Irish government building, replacing the building's existing WindowMaster NV Advance system with a KNX/MotorLink hybrid architecture combining natural and mechanical ventilation. The contract value is not disclosed but exceeds DKK 1 million (€134,000), the threshold triggering mandatory investor disclosure under WindowMaster's communications policy.

WindowMaster International A/S (CSE: WM) is a Copenhagen-based ventilation technology company listed on the Copenhagen Stock Exchange, specialising in natural ventilation, hybrid ventilation, window automation and building control integration. For FY2024, WindowMaster reported revenue of DKK 285.8 million (€38.3 million), down 4.8% year on year, with EBITDA of DKK 27.4 million (€3.7 million). 

The company operates across Buildings (project integration), Products (distribution and manufacturer supply) and Safety (fall safety equipment). The Irish contract falls within the Buildings segment. The contracting party and specific building are not disclosed.

The structural driver is Ireland's overheating problem in the existing building stock. Irish research cited by WindowMaster indicates that ventilative cooling potential in Ireland exceeds demand by more than 3.5 times, meaning hybrid ventilation systems can materially reduce mechanical cooling loads in buildings currently relying on energy-intensive air conditioning.

This is directly relevant to the Irish public sector estate, which is subject to the Sustainable Energy Authority of Ireland's mandate requiring a 50% reduction in public sector energy use by 2030 versus a 2009 baseline. Government buildings undergoing refurbishment must demonstrate compliance pathways under NZEB standards and BER requirements, which hybrid ventilation systems directly support.

For the sector , the Irish government contract is strategically significant beyond its value. It is a repeat client win, the building previously used WindowMaster's NV Advance system, demonstrating product lifecycle loyalty that underpins the Buildings segment model. 

It also extends the company's Irish reference portfolio in a market it has identified as a growth focus for hybrid ventilation, at a moment when Irish commercial and public sector refurbishment activity is accelerating ahead of NZEB compliance deadlines.
