An Advisory Report outlines cost-effective measures for saving energy and recommends various green technologies and the short, medium and long term paybacks which can be expected following implementation.

Air Tightness Testing & Measurement Association (ATTMA)

The Air Tightness Testing and Measurement Association (ATTMA) ensures that its members maintain high standards of service in air leakage testing and measurement applications. All members of ATTMA must be accredited by UKAS in accordance with ISO/IEC 17025, with a scope covering air tightness testing to ATTMA Technical Standard 1 and BS EN:13829 (2001).

ATTMA membership is required to demonstrate competence in the completion of air leakage testing on non-domestic buildings in the UK, in accordance with the current Building Regulations Part L. The alternative (for domestic air testing) is BINDT (the British Institute for Non Destructive Testing.

Developing the role of airtightness evaluation in environmental control. The building industry can make important contributions to reducing the UK's emissions of greenhouse gases if it can design and construct buildings that are less prone to air leakage through the external envelope.

D

Department for Energy and Climate Change (DECC)

The Department of Energy and Climate Change (DECC) is a British government department created on 3 October 2008 by Prime Minister Gordon Brown to take over some of the functions of the Department for Business, Enterprise and Regulatory Reform (energy) and Department for Environment, Food and Rural Affairs (climate change)

Design Reiews

A comprehensive review carried out by experiecned air-tightness consultants.

Design Workshops

A simple but effective method of interrogating the air-tightness strategy and key drawn details.

Display Energy Certificate (DEC)

All public buildings require a Display Energy Certificate which shows the energy usage of the building and its overall energy performance on a scale of A-G, where A indicates the highest level of energy efficiency. The rating is calculated using the data gathered from the building's gas, electricity and water meters. A detailed survey of the building must be performed by a certified assessor and the resulting certificate and Advisory Report (AR) must be lodged by a government-approved certification scheme. The DEC is based on actual gathered operational data.

Stroma was the first company in the UK to lodge a live DEC. Our team of fully employed, certified energy assessors can carry out the survey, generate the certificate and lodge it with the government; Stroma was also the first 'live' certification scheme in this field in the UK.

Energy Assessor

An energy assessor is an individual who is a member of an accreditation or certification scheme.

Energy Audit

An energy audit is an inspection, survey and analysis of energy flows in a building, process or system with the objective of understanding the energy dynamics of the system under study. Typically an energy audit is conducted to seek opportunities to reduce the amount of energy input into the system without negatively affecting the output(s).

Energy Management

A continuous planning process that is used to accomplish the efficient use of energy in a building or system.

Energy Performance Certificate (EPC)

All commercial properties require an Energy Performance Certificate (EPC) which rates the energy efficiency of the building on a scale of A-G, where A signifies the highest level of efficiency. Unlike the DEC (which gives an Operational Rating) the EPC provides an asset rating of the building fabric and fixed services, based on a survey of the building. The survey must be performed by a certified assessor and the resulting certificate and Advisory Report must be lodged by a government-approved accreditation scheme.

Stroma was the first company in the UK to lodge a live commercial EPC. Our team of fully employed, certified energy assessors can carry out the survey, generate the certificate and lodge it with the government. In addition, we were the first live certification scheme in this field.

Energy Performance of Buildings Directive (EPBD)

The Directive on the energy performance of buildings (EPBD) is the Directive 2002/91/EC (EPBD, 2003) of the European Parliament and Council on energy efficiency of buildings.

• Design Stage commissioning plan and TER/BER calculations

R

RdSAP

Reduced Data Standard Assessment Procedure (RdSAP) is the government-approved program used to carry out an energy assessment on an existing residential property in order to generate an EPC. The pre-fix reduced data acknowledges that the assessor will have to make assumptions about the building - such as age, wall thickness, type of insulation - when carrying out the assessment due to the absence of design information.

Stroma has developed its own industry-leading RdSAP software which is available free of charge to all Stroma-certified DEAs

Retrofit

Retrofitting refers to the addition of new technology or features to older systems. An example of this is car customizing, where older vehicles are fitted with new technologies: power windows, cruise control, remote keyless systems, electric fuel pumps, etc.

The Regulatory Reform (Fire Safety) Order 2005 (RRO)

As part of the government's commitment to reduce death, injury and damage caused by fire, regulations have been reviewed and a number of changes implemented through the Regulatory Reform (Fire Safety) Order 2005. Implemented in October 2006, the RRO applies throughout England and Wales and contains fire precautions and duties which are necessary to protect both people and buildings in the event of a fire. It also requires that a fire risk assessment be carried out annually on every non-domestic building, including:

• Shops
• Offices
• Sleeping accommodation (hotels, hostels etc.)
• Residential care and healthcare premises
• Pubs and entertainment venues
• Educational establishments
• Factories and warehouses
• Small, medium and large places of assembly
• Theatres and cinemas
• Open air events
• Transport premises and facilities

This assessment can only be completed by a competent fire risk assessor. Responsibility for compliance lies with the "responsible person".

Under the Order, anyone who has control in a building or anyone who has a degree of control over certain areas or systems may be designated a "responsible person". For example it will be the employer for those parts of premises they have any control over; the managing agent or owner for common parts of a premises such as corridors and stairways; or common fire safety equipment such as fire warning systems or sprinklers. It will also be the occupier of premises that are not workplaces such as a chairperson in a parish hall.

Any other person who has some control over a part of a premises may be the responsible person in so far as that control extends. Although in many premises the responsible person will be obvious, there may be occasions when a number of people have some responsibility.

Renewable Heat Incentive (RHI)

To meet our 2020 15% renewable energy target, we need to develop new ways of generating renewable energy in all sectors, including heat. Heat generated from renewable sources accounts for approximately 1% of total heat demand this may need to rise to 12% to hit our binding EU targets.

Renewable Obligation Certificates (ROC's)

A Renewables Obligation Certificate (ROC) is a green certificate issued to an accredited generator for eligible renewable electricity generated within the United Kingdom and supplied to customers within the United Kingdom by a licensed electricity supplier. One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated.

We provide support for our 40,500 members worldwide in the form of training, technical services, publications and events, and set standards for the education of architects, both in the UK and overseas.

S

Simplified Building Energy Model (SBEM)

Simplified Building Energy Model (SBEM) is the computer program used to produce an evaluation of the monthly carbon emissions of a non-domestic property. It is acknowledged by the government as part of the national methodology for calculating the energy performance of a building and thus is used as the calculation tool for producing non-domestic EPCs.

Standard Assessment Procedure (SAP)

Standard Assessment Procedure (SAP 2005) is the process required for a new residential property at both design stage and upon completion to calculate energy consumption and ensure compliance with Building Regulations. Once the assessment has been carried out on the completed building, an Energy Performance Certificate (EPC) is issued.

Stroma's team of fully certified, fully employed energy assessors can carry out the SAP assessment and generate and lodge the EPC. Stroma Accreditation provides training and certification services for on construction domestic energy assessors.
