Reducing energy
& carbon: |
|
Gazeley takes a four phase approach when considering energy and therefore carbon reduction opportunities:
|
 |
Design the building to be more energy efficient in
the first place.
We assess the natural features of the site – for example the wind flow patterns, the tracking of the sun, the hydrology and the flora and fauna – and then discern
what these features inform in terms of building and landscaping design.
By way of example, we try to orientate the building and the offices to take advantage of the wind and the sun, using these natural elements to reduce the need for
mechanical systems in the building, and we optimise the design of the building envelope to reduce the need for artificial lighting and heating or cooling.
As well as creating the obvious environmental benefits, this approach is aimed at reducing operational costs and maintainance costs for
our customers. |

Use the energy which we have to use in the building
more efficiently
We know that the major sources of energy use in warehouse buildings are the lighting, heating and cooling systems.
Gazeley will always seek to specify and install the most energy efficient systems. For example the warehouse lighting features the very latest T8 lighting technology
linked to motion detectors and daylight saving controls.
This means that the artificial lighting level fluctuates depending on the daylight available, and the motion detectors dim the lighting down if the warehouse aisle
is not being used. The light fittings themselves have a much longer life than many systems on the market. Gazeley is the first in the sector to have formalised a global
purchasing arrangement with the industry leading supplier of this equipment – a benefit which is passed directly to
our customer.
As well as creating the obvious environmental benefits, this approach is aimed at reducing operational costs and maintainance costs for
our customers. |

Pioneering technologies
When we have reduced the need for energy in the building design, and then mitigated the amount of energy that we have to use, we will consider an appropriate mix
of pioneering technologies and renewable
energy opportunities.
Gazeley has pioneered the delivery of numerous technologies on warehouse buildings. Examples of this are the solarwall schemes which we have delivered across Europe
and in China, and also the ETFE rooflights on our building at Chatterley Valley in the UK.
Why do we believe ETFE rooflights are interesting? Because they are designed to prevent night time light pollution from the building, whilst reducing air leakage and
increasing insulation. The material is also completely recyclable at the end of the building’s life.

Renewable energy
Gazeley has directly delivered numerous renewable energy projects using technologies such as solar thermal, ground source heat pumps, solar photovoltaic arrays and
wind turbines, however we have recently formalised arrangements with a renewable energy developer in order to major on full roof-top solar photovoltaic arrays and
biomass / combined heat and power projects across the world.
By way of example on the rooftop solar proposition, our renewable energy development partner has recently modelled a project for a customer of Gazeley’s in the UK.
Taking advantage of the present Government backed Feed In Tarriff (which is a fiscal incentive instrument to encourage investment in renewable energy technologies) a
fully funded model has been established which comes at no cost to our customer. In this particular case, assuming our customer enters into a power purchase agreement
with the renewable energy developer partner the possible operational cost savings for our customer could amount to in excess of £6 million over 25 years whilst going a
long way towards rendering the building carbon neutral without the need for offsetting.

our customers. |
