What Drives a Green Specification? Ian Elmer Technical Services Manager AMTECH Group
The Impact of Climate Change “Scientific evidence points to increasing risks of serious, irreversible impacts from climate change [that] threatens the basic elements of life for people around the world” Stern N., 2006: ‘The Economics of Climate Change – The Stern Review’. Cambridge: Cambridge University Press.
International Context • The Kyoto Protocol (1997) • Sets out commitments to reduce Global Warming Gas emissions, including a commitment for the UK to reduce emissions by 12.5% between 2008 and 2012, below 1990 levels. • UN Climate Change Conference (Copenhagen 2009) • Held to agree a framework for climate change mitigation beyond 2012. • Copenhagen Accord drafted by the US, China, India, Brazil and South Africa as a ‘Meaningful Agreement’ with further discussions to follow in 2010.
Drivers for Change • The main drivers for climate change and sustainability: • Legislation • Performance Standards • Financial Incentives
Drivers for Change • Legislative Measures
European • Energy Performance of Buildings Directive (EPBD) • Requires member states to improve the energy efficiency of buildings, through minimum energy performance standards and certification and requirements for plant inspection. • All buildings that are constructed, sold or rented are required to have an Energy Performance Certificate.
National The construction industry constitutes a significant portion of UK economic output and employment, while its output has a major impact on the environment. • 40% of total UK CO2 emissions are from buildings, of which: • 78MtCO2 from public sector and commercial buildings* • 149MtCO2 from residential buildings* *2008 figures
National UK Legislation in place: • The Climate Change Act 2008 • Aims to reduce greenhouse gas emissions by 80% by 2050 • Includes and interim target of reducing emissions by 34% by 2020 • The Energy Act • Implemented at the same time as the Climate Change Act • Allows the introduction of a feed-in tariff for small scale, low carbon electricity generation up to 5MW scale
National • Part L of the Building Regulations. Updates to include: • 25% improvement in regulated emissions from 2010 • 44% improvement in regulated emissions by 2013 • Potentially 70% improvement in regulated emissions by 2019 (according to Definition of Zero Carbon) • Other ambitions such as new homes to be zero carbon by 2016 have also been announced
National The ‘Definition of Zero Carbon’ approach: • Building Regulations to be underpinned by a very high minimum standard of energy efficiency • Minimum standard of carbon compliance to be achieved through energy efficiency, LZC technologies and directly connected heat. • Solutions for dealing with residual emissions resulting from applying these standards (e.g. Upgrading the efficiency of neighbouring buildings)
National The F-Gas Regulations • Framework for reducing emissions of fluorinated greenhouse gases (F Gases). • Sets out prescribed offences and penalties relating to fluorinated greenhouse gases covering subjects such as use, recovery, reporting, labelling and certification.
National Strategy for Sustainable Construction • Joint industry and Government initiative intended to promote leadership and behavioural change in construction • Includes a number of key targets such as: • Reduce per capita consumption of water in the home to an average of 130 l/p/day by 2030 • 50% reduction of construction, demolition and excavation waste to landfill by 2012 when compared to 2008. • Reduce CO2 emissions (UK total) by at least 60% by 2050 (based on 1990 levels).
Drivers for Change • Performance Standards
Performance Standards Main methods for providing performance standards: • BREEAM (Building Research Establishment’s Environmental Assessment Method) - UK • Code for Sustainable Homes - UK • LEED (Leadership in Energy and Environmental Design) - US
Performance Standards BREEAM: • Most widely used assessment method in the UK • Sets standards for best practice in sustainable design and uses a points scoring system describe a building's environmental performance • Covers a number of topics with points associated to them that combine to give a building a BREEAM credit rating
Performance Standards The main topics are as follows: • Management • Health and Well Being • Energy • Water • Materials and Waste • Pollution
Performance Standards There are mandatory minimum standards within BREEAM and these can be used as an indication of whether it is possible to achieve a desired rating for a building: • For example, for a building to achieve an ‘Excellent’ rating it must have excelled in every environmental category within BREEAM. • Government departments require BREEAM ratings of all their buildings; most local authorities require BREEAM as part of planning approval for developments over a certain size.
Performance Standards There are a number of versions of the BREEAM scheme tailored to a variety of buildings, among them: • BREEAM Offices • BREEAM Healthcare • BREEAM Education • BREEAM Retail • BREEAM Other Buildings
Performance Standards Code for Sustainable Homes: • National standard for the sustainable design and construction of new homes • Provides a single framework for house builders to establish environmental standards • Measures the sustainability of a new home against nine categories of sustainable design, rating the 'whole home' as a complete package
Performance Standards Uses a one to six star rating system to communicate the overall sustainability performance of a new home • All new publicly funded housing must be rated against the code. • Voluntary for new private sector homes, unless there is a local planning requirement. • Publicly funded housing required to reach at least code 3.
Performance Standards LEED: • United States based code for Leadership in Energy and Environmental design launched by the US Green Building Council • Shares common components and goals with BREEAM in driving improvement in building design • In the UK, interest in LEED is growing with 66 LEED Accredited Professionals in the UK.
Performance Standards Main difference between LEED and BREEAM is method of assessment: • BREEAM uses trained assessors who report to the BRE to validate the evidence and issue a certificate • LEED does not require trained assessors, though further credit is given if accredited professional (AP) is used. • Client provides evidence (with assistance of AP) then submits to US-GBC for evaluation.
Performance Standards Other differences: • Fixed to the ASHRAE standards and the US way of thinking • Credits are generally linked to the US Dollar (especially the energy credits), which means that if the exchange rate is unfavourable, then the building's rating could suffer. • Niche market in UK at present, but interest is growing
Drivers for Change • Financial Incentives
Financial Incentives Mechanisms used to provide incentives to improve the performance of buildings include: • Tax reliefs • Penalties • Grant funding • Carbon trading
Financial Incentives Tax relief: • Main scheme that the Government offers to provide support for business investment in low carbon technologies is the Enhanced Capital Allowances (ECA scheme) • Enables businesses to claim 100% first year capital allowances on qualifying plant and machinery • Two schemes that affect the building services industry: • Energy Saving Plant and Machinery • Water Conservation Plant and Machinery
Financial Incentives Examples of plant and machinery that qualify for ECA: • Air-to-air energy recovery • Automatic monitoring and targeting (AMT) • Combined heat and power (CHP) • Motors and drives • Rainwater harvesting equipment • Meters and monitoring equipment • Flow controllers • High efficiency taps
Financial Incentives Penalties: • The legislative schemes covered previously outline penalties for non-compliance: • Building Regulations – Alteration or removal of work, financial penalties • Energy Certificates – Financial penalties for non-compliance • F-Gas regulations – Enforcement and prohibition notices as well as fines.
Financial Incentives • Renewables Obligation: • Government scheme introduced to incentivise electrical generation from renewable sources in the UK • Licensed electricity suppliers are obliged to source a percentage of their energy from renewable sources • Obligation achieved by surrendering required number of Renewables Obligation Certificates (ROC’s) to the regulator. • Failure to do this results in a financial penalty called a ‘buy-out’.
Financial Incentives Grant funding: • A number of grant funding schemes are available to promote energy efficiency: • Low Carbon Buildings Programme • Bio-energy Capital Grants Scheme • Microgeneration Strategy • Energy Act
Financial Incentives Low Carbon Buildings Programme (LCBP): • Two phases to the Low Carbon Buildings Programme • Phase 1 – allowed householders, community organisations and public and non-profit sector groups to apply for grants for the installation of technology such as photovoltaics, solar thermal hot water and bio-energy. • Phase 2 – provides similar grants for public sector building owners (schools, hospitals, housing associations and local authorities) and charitable bodies to install microgeneration technology.
Financial Incentives Bio-energy Capital Grants Scheme: • Funded by the Department of Energy and Climate Change • Promotes efficient use of Biomass for energy and heat generation • Awards capital grants toward the cost of equipment such as biomass heat boilers and CHP • Currently aimed at businesses, organisations and charities in commercial, industrial and community sectors
Financial Incentives Microgeneration Strategy: • Government strategy to allow electricity companies to claim for Renewable Obligation Certificates (ROC’s) • Companies that produce less than 50kW are entitled to: • Claim ROCs either monthly or annually • Appoint an agent to sell ROCs on their behalf • Use their own renewable energy without selling it first • Sell surplus electricity to energy companies
Financial Incentives Energy Act: • Aims to support the increase in renewables required to meet the UK carbon reduction targets set out in the Climate Change Act 2008, in particular by: • Strengthening the Renewables Obligation by supporting low carbon technologies whilst reducing the support of more established technologies such as co-firing. • Introducing ‘feed-in tariffs’ to guarantee that small scale generators will receive payment for generating electricity from low carbon electricity generation projects. • Introducing a financial mechanism to encourage the installation of renewable heat at all scales, industrial to household.
Financial Incentives Carbon Trading: • The EU Emissions Trading Scheme is the main carbon trading initiative at present. Main principles as follows: • Participating companies monitor and annually report their CO2 emissions • They are then obliged to return an amount of emission allowances to the government equivalent to their emissions that year. • They are allowed to buy or sell emission allowances in order that they can achieve their targets at least cost
Financial Incentives In the UK: • CRC Energy Efficiency Scheme: • Similar to EU Emissions scheme, organisations buy allowances equal to their annual emissions • Emissions target is achieved by placing a ‘cap’ on the total allowances available to each group of CRC participants • Individual organisations can determine the most cost-effective way to reduce their emissions, e.g. buying extra allowances, investing in ways to decrease the number of allowances they need to buy. • Comes into force in April 2010
Financial Incentives Other schemes: • Clean Development Mechanism: • Aimed at smaller firms not covered by the main schemes • Participants are issued with Certified Emissions Reductions certificates for every tonne of carbon they stop from being emitted into the atmosphere. • These can then be sold to governments and companies to meet their Kyoto targets and emissions allocations.
The Specification The role of the specification in reducing carbon emissions: • All of the drivers for change referred to previously have direct relevance in the building services industry • The specification is a key document which can impact heavily on the sustainable design of a building from project brief to detailed design. • Provision of information is extremely important to ensure what is installed matches the intention of the consultant and client so the specification is central in disseminating:

The Specification and Financial Incentives:
Summary In summary: • There is a commitment in the UK to reduce carbon emissions • The drivers for change are primarily driven by legislation, performance standards and financial incentives • The production of the Building Services Specification is key to the design of sustainable buildings at all stages of the project, from initial brief through to detailed design and construction
