Environmental Sustainability

A holistic approach to creating

Energy Efficient Buildings

Tritax Symmetry recognise the essential role of the built environment in delivering sustainable development, we understand and embrace the need to have a positive impact on the environment. We therefore adopt a holistic approach to creating energy efficient buildings, sensitive to the climate and environment. We believe that the approach to sustainable development must be tailored for every project to meet the needs of the client and the requirements of the project stakeholders.

In our opinion some of the most relevant definitions and objectives of sustainable development are incorporated in the following, the ethos of which we are committed to reflect in all new development:

Brundtland Commission 1987

“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs”.

UK Government Initiative

  • – Social progress which recognises the needs of everyone
  • – Effective protection of the environment
  • – Prudent use of natural resources
  • – Maintenance of high and stable levels of economic growth and employment

The Triple Bottom Line Objective

The concept of measuring performance in terms of social and environmental performance, as well as financial return.

In order to fulfil our objectives as outlined above, we undertake the following detailed analysis for each new project we embark on:

BREEAM

Tritax Symmetry support and use BREEAM as a guideline for sustainable building practices and embraces local authorities’ environmental requirements and objectives. BREEAM is the Building Research Establishment Environmental Assessment Method. It is the most widely used and robust method available for measuring and demonstrating the environmental performance of buildings.

Energy in buildings

Tritax Symmetry are committed to delivering energy efficient, low carbon and cost effective buildings, which we assess through building operation energy usage modelling. This is vital because Buildings are responsible for about half of all carbon dioxide emissions in the UK.

Healthy and productive buildings

Tritax Symmetry deliver workspaces designed to provide the most comfortable working conditions by optimising daylight, ventilation, heating and cooling systems.

Renewable Energy

Tritax Symmetry fully investigates the use of integrated renewable energy systems on all projects, in order to minimise the erosion of exhaustible materials e.g. fossil fuels.

Sustainable Design

Tritax Symmetry consider the following strategies in all new projects:

Reduce CO2 emissions and decrease the use of fossil fuels by

  • employing renewable energy sources wherever possible
  • reducing transport during construction by sourcing materials and components locally
  • implementing facilities to minimise car travel for future employers and clients
  • avoiding mechanical cooling and investing into natural cooling and natural ventilation
  • designing for a maximum use of daylight
  • designing automatic lighting controls and fit low energy and LED lighting throughout the site
  • minimise the use of finite sources and use renewable sustainable elements instead
  • develop a green transport plan in collaboration with local councils

Reduce water usage by

  • implementing rainwater harvesting systems into the building design
  • installing grey water harvesting systems where appropriate
  • installing water efficient fittings, such as low flow taps, low flow showers, automated controls on urinals and dual flush, low flow WCs
  • fitting water meters
  • installing water leak detection systems and monitoring water consumption

Reduce waste by

  • providing recycling facilities during and after construction
  • use recycled components and recycled aggregates wherever possible
  • considering the possibility of creating energy from waste
  • considering off-site manufacture

Increase biodiversity by

  • investigating the ecological value of the site
  • employing an ecologist to assure maintaining or increasing the ecology on the site
  • implementing green or brown roofs to increase biodiversity and help prevent flooding
  • employing flood risk minimisation measures

Reduce pollutants by

  • using non-hazardous healthy building materials with low embodied energy and a good life cycle analysis
  • avoiding toxic materials such as formaldehyde as much as possible
  • installing low NOx heating systems
  • fitting oil interceptors in car parks
  • designing external lighting to minimise light pollution

Create health and well-being by

  • improving the indoor air quality through ventilation and healthy breathable building materials
  • providing thermal comfort by creating temperature controlled environments
  • providing open spaces and green recreational areas for occupants/users
  • providing views out
BREEAM assessment

To review all environmental aspects of the site and the proposed building with a view to achieving the highest rating possible.

Appointment of ecologist as part of the building team

To investigate the ecological value of the site with a view to maintaining or enhancing the ecological value of the site to the benefit of all.

Renewable energy sources consideration

To investigate the alternative sources of renewable energy and to determine its suitability for the site and buildings.

Increased air tightness

To obtain an air leakage rate for the building at least 50% better than that required under current Building Regulations.

Increased roof lights to warehouse

To increase the percentage of roof lights from the institutional level of 10% of the roof area to 15%, to improve the natural daylight provision.

Appointment of mechanical and electrical consultant for energy calculation

To ensure the systems installed provide heating, lighting and cooling with minimum energy usage and wastage.

Design of offices to enable fresh air ventilation & natural daylighting

To review the design and alignment of the offices to maximise the use of fresh air ventilation and natural daylight.

Maximise daylighting

By use of sun path analysis, ensure that the alignment of the offices on the site maximises daylighting.

Provision of solar shading

To reduce heat gain within offices during the summer months with the benefit of more natural cooling.

Provision of tinted glass to improve solar control

To control heat gain within the building during the summer months.

Provision of high efficiency plant

To constantly review the latest products to reduce energy usages.

Incorporation of building management system and energy metering

To enable the building user to monitor the building system to reduce and control energy usage.

Provision of user log books and building manual

To enable the building user to manage and maintain the building systems to maximum effect for minimum energy usage.

Seasonal commissioning

To arrange for the consultant to visit and carry out an assessment in use in two different seasons following completion.

Pir lighting control to offices

To minimise energy usage whilst offices are not occupied.

Provision of photocells & time clock to external lighting

To control external lighting in relation to outside light levels.

Design of lighting to minimise light pollution

To review the location of all external lighting to minimise upward glare.

Travel and transport plan

To help encourage less reliance on single occupancy private car travel.

A collective term for all plant and animal material. Includes burning or digesting forms of biomass to produce energy. Examples include wood, straw and energy crops such as willow and poplar grown on short rotation.
