Refurbishing existing buildings to reduce energy use is a priority worldwide greenhouse gas emissions. Millions of around the globe have old roofs that are poorly insulated, but with large roof surface areas could potentially provide significant renewable generation. Often, photovoltaic panels simply added onto regardless thermal integrity. However, due weathering, frequently need repairs over ...

Overview Both the technologies and design concepts exist for a new generation of low-energy buildings that outperform today’s typical high-performance buildings. Cultural barriers, however, are a primary inhibitor of the widespread construction of these buildings. This paper first gives examples of existing technologies and design concepts exceeding today’s best practice, followed by successful...

The British government has ambitions to achieve net-zero carbon emissions countrywide by 2050, with their largest challenge being from the construction industry. Approved Document L sets standards for fabric performance of buildings regulate consumption fuel and power, thereby allowing easier transition all-renewable grid electricity phasing out fossil fuels. Whilst this approach shown success ...
