All Party Group on Climate Action Meeting

EVENT OVERVIEW

The purpose of the All Party Group on Climate Action is to provide a forum for discussion between politicians, NGOs, business leaders and academics, to drive progress on climate action and sustainable development in Northern Ireland.

Local business Fraser Millar recently facilitated a site visit for members of the All-Party Group on
Climate Action at the company’s 219-unit Lancaster Park development in the Four Winds area of
Lisburn and Castlereagh, where cutting edge Passivhaus construction techniques are delivering
significant reductions in household energy use.

Lancaster Park is Northern Ireland’s first Passivhaus certified private housing development. The
company recently launched the country’s second Passivhaus development – Beaufort Green –
located on the Comber Road in Carryduff.

About Passivhaus
A concept developed in Germany 30 years ago, Passivhaus refers to dwellings that have been
constructed to meet rigorous energy efficiency standards, meaning that they maintain an almost
constant temperature.

Passivhaus design is centred around five key principles:

• Insulation (same insulation – the company uses more and fits it better)

• Triple glazed windows and doors

• Airtightness construction

• Mechanical heat recovery ventilation

• Thermal bridge-free detailing

Passivhaus principles are setting a new benchmark for energy efficiency in the housing market, which
supports homeowners, and far exceeds Northern Ireland’s current building regulations.
