In 2019, the UK’s Ministry of Housing, Communities and Local Government (MHCLG) – as it was then called – published an MMC Definition Framework (see my earlier article,.
At the same time, our innovative approach facilitates a well-integrated design that addresses the complexities of Passivhaus via high-quality fabrication.. What is Passivhaus?.Passivhaus is a well-established, international building performance standard that delivers resilient, ultra-low energy consumption buildings, whilst maintaining the highest levels of occupant thermal comfort and air quality experience..
This is delivered through a keen focus on a fabric first approach that seeks to reduce space heating demand which can be met either through useful solar gains, internal gains or via modern, high efficiency and low carbon heating systems..The facade performance in a Passivhaus building goes well beyond current UK Building Regulations, though a combination of highly insulated walls, high-performing windows and by ensuring “thermal bridging” around windows, doors and junctions is reduced to as close to zero as possible.This contrasts with traditional building construction, where these elements account for upwards of 10% of the building’s heat loss..
The design must achieve the following targets to gain Passivhaus certification:.A heating energy demand of < 15 kWh/m²/yr or a maximum required heating power of 10 W/m2.
Avoid overheating or have a cooling system demanding < 15 kWh/m2/yr.
Achieve an air tightness of ≤ 0.6 air changes/ hr @ n50.scale, adjacency, proximity etc.
lends itself to the use of Configurators, which can be designed by our.Creative Technologies.
team, to automate the design process..This isn’t a necessity – many clients have reported that just the process of defining and writing down their own rules processes is valuable, and the manual test fits are already far quicker than bespoke designs..
