Sustainable buildings: Does the OECD practice what it preaches?
Today we’re publishing the last in a series of three articles by Liisa-Maija Harju, Environmental Coordinator in the OECD Operations Service on the OECD’s environmental performance.
Did you know that the Eiffel Tour is going green? The planned €25 million investments will improve the landmark’s energy performance by 30%. The Eiffel Tour will start to generate its own electricity and hot water by the end of 2013. Solar panels and small, vertical wind and hydraulically-powered turbines will be installed 57 metres above the ground. Ninety-five per cent of the new lighting will be of LED-type that has a longer lifespan and consumes less energy than conventional eco light-bulbs.
Small, individual investments like this are needed because the building sector contributes up to 30% to annual global greenhouse gas (GHG) emissions and consumes up to 40% of all world energy, according to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Not to mention that the big clock is ticking: the World Meteorological Organization announced that the amount of GHGs in the atmosphere reached a new record high in 2011.
Fortunately the building sector offers the largest potential for climate change mitigation at low-cost in all world regions, and sustainable building practices are becoming popular. In these types of buildings natural resources like energy and water are used efficiently; emissions, pollution and waste production is minimized; and occupants’ health and employees’ productivity are improved.
To tackle the climate challenge, private sector investments in buildings, transport and energy infrastructure will need to be shifted toward low-carbon options. Choices made today about the types and location of critical infrastructure will lock-in costly future emissions and the vulnerability of our economies to a changing climate. The OECD has developed a Green Investment Policy Framework which identifies how governments can improve the conditions to shift and scale-up private investment towards greener infrastructure.
The International Energy Agency’s Sustainable Buildings Centre (IEA-SBC) agrees, and recommends a holistic approach for lowering buildings’ energy consumption. Aiming for net-zero energy consumption, improving the energy efficiency of existing buildings, applying for building energy labels or certificates, as well as improving energy performance of building components and systems are some of the most cost-efficient ways to save energy in buildings. Appliances and equipment used within buildings should also be selected according to these guidelines. The Eiffel Tour is definitely on the right track!
But building occupants’ consumption habits can also have a significant impact. The results of an OECD survey on “Greening Household Behaviour” show that government policies and mixes of instruments can encourage the best changes towards occupants’ sustainable consumption habits. Regulations can incentivise building owners and services providers to offer an infrastructure and services that support positive behavioural changes. The presence and quality of collection services for recyclables, for example, is found to increase recycling participation and intensity. Providing the right economic incentive has also proved to be useful: price-based incentives encourage energy and water savings.
We at the OECD’s Operations Service have listened to these recommendations. One of the main goals we have set for ourselves within the Organisation’s internal greening strategy is to obtain the French High Environmental Quality (La Haute Qualité Environnementale® Exploitation, HQE®E)- environmental certification for the five major buildings in which we operate in France.
Our buildings have indeed a significant impact on total GHG emissions of OECD operations: in 2011 the overall GHG emissions of our operations were 8,535 tCO2e, an 8% decrease from 2010. Due to the nature of our work, travel on missions is the main contributor to this GHG footprint (64%), followed by buildings (20%) and commuting (16%).
The HQE® is the most frequently applied building certification scheme in France. It is a voluntary approach aiming to limit the short and long-term environmental impact of a building’s operation and maintenance, while guaranteeing healthy and comfortable living and working conditions for the occupants. The certificate’s 14 indicators are used to measure and manage buildings’ quality in four areas: construction, management, comfort, and as well as health. In addition to energy and emissions the indicators are used to measure topics like green procurement and waste management.
We are approaching our HQE®E-certification goal: two of the five buildings are now HQE®E – certified, and we are working towards certifying the OECD Conference Centre and Château de la Muette as well as one more building in which our employees work. These successes were made possible thanks to the support of the Secretary-General of the OECD, the know-how of all operations service teams involved, and the engagement of our employees.
While our strategy has so far proven to be successful, it should be remembered that HQE®E and other buildings’ environmental certificates available on the market only encourage the buildings’ owners and service providers to improve buildings’ environmental quality and performance. The certificates do not yet allow for the measurement of resilience. How do buildings react to impacts or risks, such as extreme weather events, caused by the environment?
