2 reasons why airtightness in Part-L must be revised

The UK government’s recent proposals to update the building regulations are not good enough, industry says. They could lead to double the heat loss compared to current industry best practice, and will lead to more expensive construction to meet our energy and emissions targets.

Airtightness in the new PAS 2035 Standard for domestic retrofit

The new PAS 2035 standard defines a risk-based approach to safe and efficient domestic renovation for low energy housing. We look at the airtightness impacts.

Double-decker cargo reduces CO2 emissions

SIGA is working with logistics partners to switch to trucks that can load double-decker, a move that will save several tonnes of CO2 a year.

Brave new world: the challenges facing modular construction

Modular and offsite construction are growing fast worldwide, as demand increases for super-insulated, airtight, low carbon new buildings. But from public perception to the need for upskilling our workforce, these new methods still face challenges if they are to take over the market.

Preparing for airtightness in concept and developed design stages

This is the second instalment of our guide running from concept to handover, what needs to happen at each RIBA stage to achieve a successful airtightness test.

Focus on renovation: What are the EnerPHit classes?

We need to retrofit millions of buildings with airtightness and insulation to achieve net zero. What is EnerPHit compared to Passivhaus, what are passivhaus principles? We give an introduction to highly efficient construction renovation projects.

Beware thermal bypass – it’s air behaving badly!

Insulation stops heat escaping by blocking conduction. But it can’t do its job properly if heat is also being carried away by unwanted air movement.

Airtightness in preliminary stages of architecture design

From concept to handover, we describe what needs to happen at every RIBA stage for a successful airtightness test.
