SAP is the Government's recommended system for
energy rating of dwellings. The Standard Assessment Procedure is
used for calculating the SAP rating, on a scale from 1 to 120,
based on the annual energy costs for space and water heating
calculating the Carbon Index, on a scale of 0.0 to 10.0, based on
the annual CO2 emissions associated with space and water
heating.
|
BREEAM is the Building Research Establishments
evaluation tool that can be used (ideally) at the design stage and
following development. Ecohomes is the equivalent
for houses. Trained BRE assessors undertake building surveys to
rate performance on measures such as materials used and the amount
or embedded energy within them; efficiency of lighting and heating
(including utilisation of natural lighting and ventilation); power
generation and use of renewables and micro-renewables (e.g. solar
PV, Solar thermal, geothermal); it also looks at issues such as
land use. E.g. physical access issues and flooding and grey water
recycling.

Whole life costing for a building aims to avoid
focusing on short term cost savings at the expense of longer term
benefits. Good environmental practice usually goes hand in hand
with good economic practice. Measures to reduce the consumption of
energy and water not only benefit the environment by reducing
emissions and conserving resources, but will also result in
substantial financial cost savings over the lifetime of the
building. The cost of energy and water are likely to rise
significantly faster than Retail
Price Index over the coming decades as resources become scarcer
and environmental controls on utility companies increase. Cost
savings that might seem marginal at today's prices could well
increase considerably as these price rises come into effect
throughout the life of the building
|
|
The Green Guide to Specification (BRE) is a
publication providing guidance for specifiers, designers and their
clients on the relative environmental impacts of over 250 elemental
specifications for roofs, walls, floors etc.
|
OMSH House builders Toolkit has been created by
WWF, sponsored by asset manager Insight Investment, to provide
clear guidance for house builders seeking to address a wide range
of sustainability issues. The toolkit, compiled by Upstream tackles
a variety of concerns including climate change, community
involvement, the sustainable use of materials, and waste. It is
available free of charge.
|
| |
The Regional Sustainable Development
Framework is used to highlight the economic,
environmental and social impacts of policies, development proposals
and other new initiatives within the region (s) and provide
information which can help to improve them from a sustainability
perspective. It can be used as the basis of an appraisal framework
for a Strategic Environmental Assessment/Sustainability Appraisal
which are increasingly being used for large and small
developments
|
| |
Sustainability Appraisal/Strategic Environmental
Assessments are increasingly used to appraise the wide
sustainability issues of developments at the design stage (e.g.
master plans; and housing development) and provide useful
recommendations and mitigation ideas to incorporate into the final
design, for example access issues (such as ensuring there is good
access by sustainable modes of transport) ;land use flooding issues
(such as use of SUDS); energy issues (for example exploring
integration of micro renewables into design; ensuring all houses
are built to at least Ecohomes 'very good'; ensuring building
materials have low embedded
energy) etc
|
| |
Environmental Impact Assessment processes could
be used more informally in improving the sustainability performance
of developments (see comments made above for Sustainability
Appraisals and Strategic Environmental Assessment.

|
Part L (1 and 2) of Building Regs The revisions
to Part L set maximum carbon dioxide emissions for whole buildings.
The regulations will apply both to the construction of new
buildings and renovation of existing buildings (with a total
surface area over 1,000m²). For new buildings, it is
anticipated that Part L will reduce carbon emissions by 25% from
2002 standards which already reduced emissions by 15%. The net
reduction of 40% from pre2002 is often used as an indicator of
improvement

Considerate Constructor's Scheme this is a
scheme developer's on which developers can register to demonstrate
their consideration for local neighbourhoods and the environment
and therefore contributes to a wide range of sustainability issues,
for example, it encourages developers to use and procure resources
wisely; reduce pollution associated with construction activities;
limit noise and visual impact associated with construction; it also
contributes towards the social dimension of sustainable development
for example, it urges developers to respect neighbours; and to
observe safety.

Sustainability Works is an online software
package. It is specifically designed to help housing professionals
and their partners deliver sustainable development efficiently,
from policy level to project delivery.
|

RETScreen Project analysis software is
effective and free Canadian software. It can be used worldwide to
evaluate the energy production and savings, lifecycle costs,
emission reductions, financial viability and risk for various types
of energy efficient and renewable energy technologies (RETs).

Life cycle analysis looks at the environmental
impacts of a product throughout all stages of its
production; use and disposal.
|
The most widely adopted voluntary standard within buildings
design and management is the Building Research
Establishment’s family of BREEAM (BRE Energy Assessment Model)
tools. These set stringent standards to which the energy and
environmental performance of new or existing buildings is rated by
trained BRE assessors. Excellent is the highest score, although all
new builds (mainly over 1000 m2 ) should at the very least aim for
a very good rating where there are explicit reasons for this. For
new buildings, BREEAM should be considered from the
building’s outset design stage.

Using Energy Efficiently
Reducing energy use
There is a wealth of information available on ways to reduce
energy use. The starting point for assistance is the Carbon Trust, which provides
free, practical help and advice on saving money by reducing energy
use. The Carbon Trust’s website contains a comprehensive
suite of fact sheets, technical guides, posters and other material.
Some guidance is developed specifically for the HE and FE
sector.
The Carbon Trust also provides support for individual
organisations, including:
- Free onsite energy surveys or detailed assessments of specific
energy efficiency issues.
- Design advice professional, independent and objective advice
covering energy efficient and environmentally conscious building
design. The service provides one day of general project
consultancy, paid for by a cash-back scheme.
Reducing energy costs
The main barriers that reduce the uptake of energy efficiency
measures are generally considered to be lack of capital, lack of
staff time and the fact that departments are generally
unaccountable for energy costs. But the increasing profile being
given nationally to rising energy costs and the impact of energy
use on climate change means that these barriers need to be tackled
across the organisation in order to achieve real energy efficiency
savings.
Despite the strong drivers from fiscal and regulatory measures,
and the financial impact of rising energy prices, the direction of
energy use from FE system buildings is likely to be upwards for the
foreseeable future. This is because educational establishments are
becoming more and more energy intensive, particularly because their
use of energy-intensive IT equipment is greater, and they use more
energy intensive equipment for research. Consequently older
buildings incorporate air conditioning or cooling equipment to
ensure acceptable ambient temperatures, while newer buildings may
incorporate these services as standard. In addition, working hours
are often longer, and buildings are used more intensively and, in
some cases, for community use outside normal operating hours.
The importance of continuing to improve energy efficiency is
therefore critical to minimise unnecessary rises in energy usage.
Larger energy users may be able to reduce their energy costs, or
obtain grants or loans through which they can make investments for
longer-term energy savings opportunities.
There are a number of ways to obtain exemption from the Climate
Change Levy: for FE organisations, the most relevant exemptions are
applied if energy is provided through a good quality combined heat
and power scheme, or if the energy is provided from renewable
sources. There are a range of grant schemes that may provide some
financial support towards installing these types of installation,
such as through the DTI’s Low
Carbon Building Programme or from local or regional funds.
Community-related projects may also benefit from the Energy Savings Trust
which has a wealth of information and experience in related
areas.

Conserving
Water
Good practice in water management takes the following steps:
- Establish levels of water use using water meters, with regular
monitoring.
- Eliminating leaks checking for underground water losses, taps
left running, taps dripping, urinals flushing continually,
etc.
- Reducing unnecessary water usage such as wasteful or
inappropriate grounds watering or overzealous wash-down of hard
standings.
- Monitoring progress relating to water consumption over
time.
- Recycling grey water and rainwater
There is a wealth of information about ways to reduce water use
available from the government-funded organisation Envirowise.
Envirowise
Produce guidance fact sheets and technical support documents
about how to approach and implement water savings initiatives, from
easy, no-cost actions through to ways to invest in cost-effective
savings.
Early actions to minimise water use can include the following
types of actions:
- Encourage good housekeeping and efficient use of water in all
areas;
- Fit flush controls to urinals in gents’ toilets
- Fit percussion taps to turn off water automatically in
washrooms; and
- Fit pistol grip controls to hosepipes.
More specific information is also available through Envirowise
including events, workshops and site visits.
The Environment Agency
Publishes a range of free literature relating to water
conservation and demand management. The information includes
details of implementing a water management plan in buildings, cost
benefits of investing in water efficient technologies,
opportunities from investing in greywater recycling systems, and
case studies.

Reducing
Waste
The Environmental Association for Universities and Colleges has
produced
an online Waste Management Guide that is targeted directly at
FE and HE (FHE) providers. The guide does not attempt to provide
comprehensive advice on managing every possible waste arising from
FHE organisations, but aims to provide a framework for building a
waste management system and then provides useful signposting to
other sources of more detailed information where appropriate. It
gives guidance on developing a structured approach to waste
management within an educational environment, advice on arranging
and contracting for disposal of waste, and information about
different types of waste likely to be encountered for disposal.
There are a number of main steps to developing and implementing
an effective and sustainable approach to waste within the
management of your buildings and estates:
- Assess your current waste how much waste is produced, what
types of waste are produced, which departments produce which types
of waste, where is the waste disposed to
- Identify opportunities for savings use the waste hierarchy to
identify where waste can be eliminated, reduced, reused,
recycled
- Establish priorities for action to establish some “quick
wins”, which activities would achieve the greatest results
(e.g. volume/weight of waste, value of disposal costs saved); the
fastest results and which would have greatest impact on staff and
learners?
- Set targets, agree data collection requirements
- Implement waste minimisation and waste management actions
- Monitor progress
- Review the results, identify successes
- Promote achievements, implement continuous improvements to the
waste management plan

Encouraging Biodiversity
This guidance provides an overview of the key drivers and issues
relating to biodiversity that can be a reference for FE providers
and for those with curriculum responsibilities in your
organisation. It describes how biodiversity can be fully integrated
into the management of your estate and how it can also be
incorporated into the overall learning provision relating to
sustainable development.
The EAUC’s practical guide on Biodiversity on Campus
The
EAUC’s practical guide on Biodiversity on Campus set out
a three-stage approach to taking action on biodiversity which you
should apply in your organisation:
Creating:
- new habitats and wildlife opportunities
- greater awareness of biodiversity across the FE
organisation
- benefits for staff and learners
- new partnerships within the FE organisation and with the wider
community
Enhancing:
- wildlife
- local biodiversity
- the work and study environment for staff and learners
Maintaining:
- wildlife habitats
- healthier campuses
- interest in environmental issues
Guidance on developing biodiversity action plans can also be
found on the
Business and Biodiversity Resource Centre’s website, on
which there are a number of publications relating to biodiversity
and sustainable development.

Purchasing
By working through the sources of guidance below, you will gain
a better understanding of how your procurement actions can make an
important contribution towards advancing sustainable development
within your organisation. The sources below provide guidance on
identifying opportunities for increasing the sustainability of your
procurement choices.
Action Sustainability
Action
Sustainability is a Social Enterprise set up to lead and
inspire sustainable procurement. It supports and facilitates the
Strategic Supply Chain group, a leading authority on sustainable
procurement whose members are Directors and Senior Managers from
the UK's leading private companies, government departments,
professional institutes and academic organisations. It provides the
latest thinking on sustainable procurement and is a good place to
start.
Forum for the Future's ‘Sustainable Procurement
Process’
Forum for the Future has developed a flowchart “The
Sustainable Procurement Process” It shows the key steps
involved in improving sustainability of procurement, as
follows:
- Reduce demand
- Specify sustainability
- Favour sustainability
- Improve suppliers
Forum
for the Future is working with a number of public sector
organisations, including councils and NHS trusts, to develop and
implement a greater quality of sustainable procurement.
OGCbuying.solutions
OGCbuying.solutions,
the trading arm of the Office of Government Commerce (OGC), is one
of the latest public sector organisations to join Forum for the
Future. Over the next three years Forum for the Future will be
working with OGC buying.solutions to increase its sustainability
credentials and improve the sustainability aspects of the goods and
services made available to the public sector under its contracts.
Working in partnership, Forum for the Future will be developing OGC
buying.solutions’ Sustainable Development strategy, reviewing
its policies and creating a sustainable procurement toolkit for
category and contract managers, to ensure sustainability is built
into procurement processes.

Transport and Fleet
Management
Supporting initiatives
The Energy
Savings Trust is the main source of information, advice and
support on ways to improve your transport management.
The Energy Saving Trust works to cut greenhouse gases and air
pollution from the road transport sector. It promotes cleaner,
lower-carbon vehicles and fuels, eco-friendly driving techniques
and low-carbon transport alternatives. It offers a free fleet
consultancy to any organisation running at least 50 vehicles, to
provide practical advice on how to reduce fleet costs, cut vehicle
emissions, improve social and environmental relations, and minimise
traffic and parking problems.
Sustrans, a leading
sustainable transport charity, works with schools to establish
cycle routes and improve public transport.
Engaging with staff and learners
Much of the emphasis will involve your organisation focusing on
engaging with staff and learners to encourage them to take a more
sustainable approach to their mobility. This could include:
- best practice urban design on and off campus to minimise the
need for cars
- reducing the need to travel e. g. using videoconferences
- car sharing this may need better planning for meetings, events
etc
- improving access to alternatives to the car
- walking or cycling particularly where trips are only one or two
miles in length
- integration with public transport working with local transport
providers to ensure clean, safe, reliable and accessible public
transport that is closely integrated with the FE estate
- providing subsidised public transport / cycle purchase
support
- fleet management audit
- encouraging advanced car driving techniques which can reduce
fuel consumption by up to 25%
Additional options could include considering adopting highly
fuel efficient cars for the organisation’s fleet such as
alternative fuels, electric hybrid. You should also take care to
address the issue of your “grey fleet” this refers to
staff who use their own cars on official business.

Environmental Management
Systems
The government-funded organisation Envirowise provides a range
of documents guiding the preparation and implementation of writing
environmental policies. Although mainly targeted at industrial
companies, the guidance is of relevance to the Learning and Skills
sector as well.
As a general rule, it suggests that the policy should contain
statements on the following criteria:
- a commitment to continuous improvement
- recognition of compliance with relevant environmental
legislation as a minimum level of performance
- the education and training of staff in environmental issues and
the environmental effects of their activities
- the monitoring of progress and review of environmental
performance on a regular basis (usually annually)
The policy statement can include any areas of relevance. For the
FE system, areas will include energy, waste, water and
transport.
You should also read the Section
on Leadership and Management. This will help you understand
where an EMS can sit within the wider sustainable development
priorities for your organisation.
