Thermal bridging in energy efficient buildings

Posted on March 29th 2012

A thermal bridge is created where materials that are relatively poor insulators are in contact across an insulation barrier. This creates a low resistance path for heat to escape from in an otherwise well insulated construction.   Limiting thermal bridges is becoming increasingly important with higher environmental standards such as Code Level 4 and the impending 2013 Part L1a Building …

Ventilation, MVHR and summer overheating

Posted on April 18th 2011

Summary Mechanical Ventilation with Heat Recovery (MVHR) systems recycle the heat from exhaust air by passing it to incoming air. This is a passive process that relies on heat exchangers with large surface areas, and it requires no additional energy input. Such a system is an advantage in winter, but in summer months there is a risk that the process …

Air Source Heat Pumps and renewable energy planning policy

Posted on October 5th 2009

AIR SOURCE HEAT PUMPS IN THE UK Air Source Heat Pumps (ASHPs) are a mature technology, and widely used in Europe. Due to their efficiency they can  greatly reduce the energy needed for heating homes. However, they are relatively new to the UK home heating market, and their status a low carbon technology is controversial here. This is partly because …

Specification of MVHR to improve performance in SAP

Posted on July 6th 2009

Mechanical Ventilation with Heat Recovery (MVHR) systems are balanced whole house ventilation systems. As well as exhausting air from wet rooms like typical extract units, they also preheat the incoming air for diffusion into living spaces. MVHR is increasingly being specified by house builders. In many instances this is because it can make a significant cost effective contribution towards the …

Zero Carbon consultation: cost of compliance

Posted on May 18th 2009

We used real case studies for the Home Builders Associates to provide a response to the worked examples included in the Zero Carbon Consultation Document. Our study found that the cost to achieve Zero Carbon including energy efficiency, Carbon Compliance (on-site) and Allowable Solutions (off-site) varies from £10,000 – £40,000 per dwelling. The most expensive required high levels of on-site …
