BREEAM & Code for Sustainable Homes

JHW are independent advisers on renewable energy and low energy building design. Our Energy and Planning team are providing advice across a range of projects for clients looking to reduce embedded energy and ongoing energy needs of commercial and residential properties.

There are a wide array of low carbon/energy efficient materials, designs and appliances on the market, making choosing the most appropriate for your needs and budget something of a challenge. With extensive experience of the installation of energy efficient technology in both new and existing housing stock, along with skills in low energy building design, we can help with your projects.

We offer you professional independent advice on the latest advances in design, technology and policy; helping you to increase your energy efficiency, compliance with regulations, reduce your carbon footprint and save money.  Our approach is straightforward and independent. Each project is different and determines the scope of works carried out. For existing property the work will generally include a thermal (infrared) survey.

For new commercial new build, a BREEAM assessment will provide a design stage assessment of a building to determine its BREEAM rating and recommend ways in which this rating can be improved.

For domestic property we will advise on energy design to both achieve owner’s objectives and where necessary to meet the required level for the Code for Sustainable Homes
