Where is the existing housing stock going?

The Part L building regulations is now thought of as a tool to reduce the CO2 emissions for the UK. An 80% cut in CO2 emissions for the UK is the current target by 2050. However a survey published by The Royal Academy of Engineering suggests that we are not on course for this target and need to address the issues of the UK building stock. The existing housing stock is still a problem, and new build dwellings are still moving slowly towards reducing their CO2 emissions.

We are currently at step two (Part L 2010) of a four step process, where by 2016, we are aiming to have net zero carbon emissions for all new build dwellings. If residential sector is to deliver, then we need to look not just at new builds but, the existing housing stock more so. Over the course of a year, < 1% of the building stock is replaced, and by 2050 the existing building stock will account for 87%. Meaning therefore, there will need to be a big push to meet the 2050 target.

What are going to be the main routes to improving the existing housing stock? The key drivers will be the BREEAM Refurbishment and the Green Deal. The BREEAM Refurbishment is similar to the Code for Sustainable Homes, with a few exceptions. It should be a big force in the future of the existing housing stock, and is due to be released on 12th June 2012. Unlike the Green deal it is brought in as a planning condition for domestic refurbishments and conversions. Were the Green Deal is a government initiative to improve the public sectors residential building stock, now also including commercial buildings.
Ecohomes has been used previously instead of BREEAM Refurbishment to assess existing buildings for planning or building control. Ecohomes will soon be made redundant to make way for the BREEAM Refurbishment assessment. From the 2nd July 2012, registrations for BREEAM Refurbishment projects can be accepted

New Energy Saving Product

I have come across some new energy saving products recently. It stood out to me as I have recent re-modelled my bathroom, and would of installed it!. It is the heat recovery shower waste pipe. It is currently going through the processes of becoming SAPappendix Q accredited. So soon we will have performance data to include in the SAP calculation and the option of specifying this new product to help in reducing CO2 emissions.

The unit uses the hot waste water from the shower, the heated waste water runs down the waste pipe transferring the heat to the clean mains water. The warmed mains water then runs to the heating system. This means that less energy is required from the hot water system. This system easily pays for itself, being cheap and easy to install.
