• Aircrete aids thermal design but beware of a shortage 

    The demand for Aircrete blocks has been steadily growing over the past few years. This can be thanked by a combination of the change in building regulations (Part L 2013) and a housing crisis that has led to strong growth in the residential sector.

  • Energy Efficient Architectural Design

    When you consider the global population is set to increase by another 2 billion by 2050 and with 70% of the world’s population living in cities, there will an unprecedented demand for energy across the planet. The opportunity for architects and stakeholders to create buildings which reduce energy use has never been more apparent.  But can energy efficiency be achieved whilst still maintaining architectural intent?

  • How the ErP Directive puts the onus on manufacturers on energy efficiency & makes life easier for consumers

    The Energy-related Products (ErP) Directive sets out a legal framework across the EU to help drive specification of more efficient products which reduce energy and resource consumption. The idea is that this will make a big contribution to meeting the EU’s ‘20-20-20’ target, namely a 20% reduction in EU greenhouse gas emissions, a 20% increase in energy efficiency, and 20% energy from renewables, which is targeted to happen by the year 2020.

  • How to achieve a good U-value 

    U-values (measured in Watts per metre Kelvin - W/m2K) measure the rate of heat loss through building elements. As they impact on both the dwelling emission rate and fabric energy efficiency targets, they ultimately govern the result of the SAP (the Standard Assessment Procedure) test used to assess a house’s energy performance. Achieving ‘good’ (low) U-values gives you the baseline for achieving and exceeding Building Regulations. But what are the best ways to achieve a good U-value? There are so many options in terms of design and materials you can be spoilt for choice. So where should you start?

  • Meeting the Target Emission Rate on CO2 with Oil or Electric Heating – It’s harder than it may seem  

    One of the two main targets that needs to be met when assessing a new domestic building against Part L 2013, together with the Target Fabric Energy Efficiency (TFEE), is the Target Emission Rate (TER) for heating. A legal requirement within Part L1A, the TER sets a minimum allowable standard for a building’s energy performance using the annual CO2 emissions of a notional building similar to the proposed building.

    One of the questions we are most commonly asked regarding the TER by designers and developers is “will this dwelling pass with electric or oil heating?” Most buildings are heated using gas, and unfortunately under current Building Regulations it is very difficult to get a new dwelling to pass and exceed the TER using electricity or oil due to the notional building method by which it is calculated.

  • Zero Carbon Homes – back again or just back on the agenda?  

    Yesterday during the Lords Report Stage of the Housing and Planning Bill, the House of Lords defeated the Government on the zero carbon homes amendment. The defeat – by 48 votes – could see the reintroduction of Zero Carbon Homes, the on-site carbon compliance standard, the Government, rather surprisingly, scrapped last July.
