BMS Building Management System A computer based control system used to control  mechanical and electrical devices such as ventilation, lighting, heating and security.  
BRE Building Research Establishment Provide expert advice on achieving better buildings, communities and businesses whilst advancing knowledge, innovation and communication. Previously a Government Establishment (became a private company in 1997).
BREEAM Building Research Establishment Environmental Assessment Method  An environmental assessment method for buildings. Sets the standard for best practice in sustainable design and is a common way to describe a buildings environmental performance.
Capital costs   Costs required to bring a project to the operational stage. Includes purchase of land, design and construction and equipment.  
Carbon sequestration   Removal of carbon from the atmosphere and long term storage.  Can be removed biologically, such as in trees, physically, such as within biomass, or chemically, through industrial related processes.  
CEW Constructing Excellence Wales Umbrella organisation for the construction industry in Wales. Funded by WAG its remit is to improve the construction process in Wales and ensure the principles of rethinking construction.
COP Coefficient of Performance Ration of energy output to the energy input. The higher the COP the better the efficiency of the equipment.  
Cross discipline   Involves two or more disciplines to enable transfer of knowledge and inclusion of necessary information for a sustainable design approach.  
DCELLS Department for Children, Education, Lifelong Learning and Skills The Department aims to improve children’s services, education and training provision to secure better outcomes for learners, business, and employers in Wales.

Ecological footprint   A measure of a person’s demand on the planets resources including consumption and waste and pollution generation.  
Environment Agency   Aims are to protect and improve the environment, and to promote sustainable development. Play a central role in delivering the environmental priorities of UK government and the Welsh Assembly Government.
EPC Energy Performance Certificate An energy performance certificate has been required in the UK since October 2008 if you are building, selling or renting a property. The certificate provides an 'A' to 'G' rating with 'A' being the most energy efficient and 'G' the least. Accredited assessors provide a report of the building including suggestions for improvement.
ESDGC Education for Sustainable Development and Global Citizenship Education that will prepare young people for life in the 21st century.  WAG have recently released a document to aid delivery of ESDGC in schools. The ‘Themes’ identified in the ‘Common Understanding’ cover the range of ESDGC and support the delivery of statutory Subject Orders, relevant frameworks, other relevant non-statutory frameworks and the 14-19 Learning Core. In response to this, NGfL Cymru are developing a microsite that supports schools with good practice examples, policy guidance and links to relevant materials and resources.  This area will also be used by DCELLS as the main vehicle for communicating with schools. http://www.esd-
Façades   External facing walls of a building.  
FIT Feed In Tariff Payments made by the UK Government for energy generated by on site renewables where excess energy is fed back into the grid.  Renewable generation systems up to a capacity of five megawatts are eligible under the new Feed-In Tariffs scheme. Five megawatts is a lot of power, so the vast majority of schools wishing to install renewable energy systems are therefore eligible.

Glulam Glued Laminated timber The majority of glulam is imported from European factories with long established third party controlled quality systems. Manufacture in the UK are committed to involve third party assessed quality systems in their own factories and are currently working to agreed European Standards. Equivalent strength glulam requires 6 times less energy to produce than steel and five times less than concrete.
Holistic   Considering buildings, infrastructure, procurement and people within sustainable design.  
ICT Information Communication Technologies Encompasses Information Technology whilst including methods of communication such as wireless signals and telephone lines.  Includes computer and network hardware as well as necessary software.  
Life cycle assessment   Consideration of each impact associated with all the stages of a process from production to disposal including raw materials, material processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling.  
Low carbon   Energy use may remain the same, but energy supply is from sources that have lower greenhouse gas emissions.  
Low energy   Energy use is reduced to low levels by reducing demand and improving efficiency.  
NGfL National Grid for Learning Cymru Managed by WJEC, funded by WAG to develop a library of interactive resources for teachers and learners at all levels.
Operational costs   Recurring costs associated with a school once it is up and running. This can include energy, maintenance, staff and consumable costs.  
Passive design   Optimise building form, façade design and space together with site layout to maximise the use of the natural environment to provide maximum comfort with minimum use of energy and mechanical systems.  
Pressurisation tests   Used to identify the airtightness of a building.  
RHI Renewable Heat Incentive A UK Government Initiative to help provide long term support for renewable heat technologies, from household solar thermal panels to industrial wood pellet boilers.
SBEM SBEM Simplified Building Energy Model (SBEM) is a computer program that provides an analysis of a building's energy consumption for non residential buildings. SBEM was developed for the Department for Communities and Local Government by BRE and is used to calculate monthly energy use and carbon dioxide emissions of a building given a description of the building geometry, construction, use and HVAC and lighting equipment.
Stakeholders   People who are affected by actions. Within a school this can include pupils, teaching staff, head teachers, community, governors, engineers, architects, local members and others.  
Thermographic surveys   Unobtrusive photographic, infrared representation of a building or part of a building that is used to identify hotspots of heat loss and air leakage by identifying hot and cold objects.
