othing should be off the table in negotiating a new EU treaty for Britain, proclaimed David Cameron in his recent speech on holding a referendum on Europe.
Negotiations will include environmental legislation, which David
Cameron said was one of those areas the government would be studying to see whether it ‘helped or hampered’ Britain. One issue that will soon be under the spotlight ahead of any renegotiation is that of Display Energy Certifi cates for public buildings of more than 1,000m2
. Currently they have to be renewed every year,
which would regularly alert building managers to any sharp spikes in energy use, caused either by issues with HVAC systems or changes in occupant behaviour. The government is proposing to extend their validity to 10 years, an idea that will baffl e property professionals who are increasingly using
Let’s hope the Chancellor examines the business case for energy certfi cates before dismissing them as EU gold plating
similar ratings systems to cut their energy bills for tenants by up to 60% (see page 26). Firms such as Hammerson and British Land are using energy ratings to identify profl igate energy use in their properties. Their work with tenants to help make buildings more energy effi cienct is leading to lower costs for tenants and better buildings for landlords. The Climate Change Property Fund specialises in upgrading offi ce property and uses acutal energy ratings to help identify the necessary energy effi ciency measures. It says these are vital in motivating tenants to help cut energy bills by up to 60%, adding that the rental value of one property increased 6% as a result. This response from hard-nosed property
people suggests that DECs are far from the business burden that some in government believe them to be.
CIBSE and other industry bodies have called on George Osborne to improve and extend DECs as one of fi ve measures encouraging green growth (see page 7). Let’s hope the Chancellor examines the business case for energy certifi cates before dismissing them as EU gold plating. This month’s case study looks at the refurbishment of Arup’s Edinburgh offi ce – a modernist 1960s building that was totally unsuited to the requirements of a 21st century offi ce (page 32). Arup conducted a thorough post-occupancy analysis, to validate the design, and to ensure that the naturally ventilated offi ce offered comfort to occupants all year round, even during the snowiest of weather.
