elcome to the March issue of BSEE. As we approach spring and the second quarter of the year, it’s set to be another interesting one for the building services industry as we await updates on Building Regulations – including a review of Part L that sets standards for the energy performance of new and existing buildings.


Small changes can make a big difference W


The ambition and resources that will be put into this Part L review are currently unknown, especially as the government already faces pressing demands for regulatory reform post- Grenfell. Action to reduce carbon emissions from the built environment is, nonetheless, urgently needed – as were highlighted in last summer’s report by the Committee on Climate Change.


In the meantime, the government has already identified improving the energy efficiency of buildings as part of its ‘Clean Growth’ Grand Challenge mission. How well a building is controlled is central to its energy performance. The Building Controls Industry Association (BCIA) has therefore rightly called for the industry to consider the importance of implementing effective building controls from the outset of building projects to meet current legislation.


In his regular column this month, BCIA president, Jon Belfield, highlights the association’s continued drive to raise standards and building performance wherever possible. As he points out, the new generation of Building energy Management Systems (BeMS) will

typically result in cost savings of between 10 and 20 per cent by ensuring energy optimisation across buildings and sites. It’s important not to forget the smaller steps that can be taken to optimise energy control in both new and existing buildings – such as maximising heating efficiency through effective use of boiler controls. Heating is frequently a starting point for efficiency improvement, as Paul Arnold of Remeha highlights in our energy efficiency feature this month, see page 22.


As a large user of energy in a building, it’s essential that the


heating system runs as efficiently and effectively as possible in order to avoid unnecessary waste, needlessly high emissions and expensive heating bills. And it presents an ideal opportunity to understand some of the small changes that can be made in order to manage the ‘e’ in BeMS as carefully as possible.
