The design team have approached the energy strategy for the development on the basis of the philosophy set out as follows:

  • Be Lean
  • Be Clean
  • Be Green


It is proposed that the first step to reduce the overall carbon dioxide emissions is to reduce the energy demand for the development using good practice efficiency measures. Passive design and energy efficiency measures proposed include:

  • Low levels of heat loss e.g. through walls, floor/roof and high air ventilation standards.
  • All lighting to be energy efficient and be complete with automatic controls
  • Energy efficient heating equipment
  • Efficient inverter driven fans and pumps


  • Heating and hot water plant will be high efficiency type
  • Sophisticated controls will be provided indicating individual electronic thermostats on radiators with maximum set-point lock positions
  • Supply and extract ventilation, complete with heat recovery, is being provided to satisfy the ‘background ventilation’ requirement set in building regulations.
  • For ventilation, the windows will be able to be opened


The development will be fully thermally modelled to assess the benefits of viable renewable and low carbon solutions. The following section reports fully on the analysis to be carried out.


BREEAM (Building Research Establishment’s Environmental Assessment Method) is a voluntary rating system for buildings. The assessment defines a building’s sustainable design and environmental impact through a number of performance criteria including:

  • Energy use
  • Water consumption
  • Material selection
  • Waste management
  • Impact on ecology
  • Accessibility
  • Occupant comfort

Buildings achieve points for each criterion met and are awarded ratings depending on the score achieved. No1 Eastside Locks is targeting a ‘Very Good’ rating.
