OUR SERVICES

Overview


At Doherty Energy we offer a wide range of services to help ensure every aspect of your project is energy efficient, compliant and value engineered for both building and running costs.


Although the services we offer can often be bundled together to ensure you have the right support from getting from inception all the way through to completion, each service can be undertaken separately.


Our Range of services is listed below

Energy Statement

Many Local Authorities require Energy Statements to support any Planning Application to demonstrate how the proposed development will meet the targets for carbon dioxide emission reductions set out in their Local Plan Polices. Each Local Authority set out different requirements on how developments will be sustainable and reduce their carbon dioxide emission and energy consumption.


In preparation of the Energy Statement, Doherty Energy will identify the targets set by the relevant Local Authority, undertake an assessment on how these can be met and produce the Energy Statement to support the Planning Application.


The Energy Statement is normally based around the Energy Hierarchy:-


  • Be Lean -     use less energy - look at reducing the energy demand through the construction, calculations for the Lean stage will be produced.
  • Be Clean -     supply energy efficiency - proposals to reduce the carbon dioxide emissions through the energy efficiency design of the site, buildings and services, an additional set of calculations is required.
  • Be Green -     use renewable energy - proposals to further reduce carbon dioxide emissions through the use of onsite low or zero carbon technologies.


Therefore, it will investigate proposals for improved fabric thermal efficiencies, better heating, hot water, ventilation and lighting efficiencies, to reduce the energy consumption and carbon dioxide emissions. Following on, any district, community or communal networks shall be identified and assessed to see if it can be incorporated.


The final step shall be to undertake a low or zero carbon/renewable technology feasibility study. The results of the above form the Energy Statement

Energy Statement - Greater London

Within the London Boroughs, the Mayor and the Greater London Authority, published ‘The London Plan’. This requires proposed developments to produce an energy assessment to demonstrate how the targets for regulated carbon dioxide emission reductions will be met.


The London Plan, March 2016, Policy 5.2 expects development proposals to make the fullest contribution to minimising carbon dioxide emissions in accordance with the following Mayor of London’s Energy Hierarchy:


- Be Lean –use less energy

- Be Clean – supply energy efficiently

- Be Green – use renewable energy


The Policy also states that the Mayor will work with boroughs and developers to ensure that major developments meet the following targets for carbon dioxide emissions reduction in buildings. These targets are expressed as minimum improvements over the Target Emission Rate (TER) outlined in the national Building Regulations leading to zero carbon residential buildings from 2016.


The Energy Statement follows the principles set out in the Energy Hierarchy and is broken down to provide the following details:

  • Estimated site-wide regulated carbon dioxide emissions and reductions (broken down for the domestic and non-domestic elements of the development), expressed in tonnes per annum, after each stage of the energy hierarchy
  • A clear commitment to regulated carbon dioxide emissions savings compared to a Part L 2013 of the Building Regulations compliant development through energy demand reduction measures alone
  • Clear evidence that the risk of overheating has been mitigated through passive design
  • Evidence of investigation into existing or planned district heating networks that the development could be connected to, including relevant correspondence with local heat network operators
  • Commitment to a site heat network served by a single energy centre linking all apartments and non-domestic building uses, if appropriate for the development
  • Where applicable, investigations of the feasibility of installing CHP in the proposed development (if connection can’t be made to an area wide network) before considering renewables
  • An initial feasibility test for renewable energy technologies and, where appropriate, commitment to further reduce carbon dioxide emissions through the use of onsite renewable energy generation

Therefore, it will investigate proposals for improved fabric thermal efficiencies, better heating, hot water, ventilation and lighting efficiencies, to reduce the energy consumption and carbon dioxide emissions.


Following on, any district, community or communal networks shall be identified and assessed to see if it can be incorporated.


The final step shall be to undertake a low or zero carbon/renewable technology feasibility study. The results of the above form the Energy Statement
