Space Heating & Cooling:

CHP (combined heat and power)

• This is the most energy efficient method of providing heat and electricity - it is most useful to larger users. This should generally be used where heat and power are needed together for a minimum of 4 000 hours per annum.
  
  

Radiators

• Thermostatic radiator valves should be fitted to all new radiators
  
  
• Such valves should not be set too high
  
  
• Place reflective sheets behind radiators on outside walls
  
  
• Remove all obstructions in front of radiators.
  
  

Heat pumps

• Pay back for these is often over long periods. Should the application be worthwhile such as for waste heat from an air conditioning plant, further advice from a manufacturer of thus should be sought.
  
  

Ventilation

• The number of fresh air changes within a building should be kept to a minimum.
  
  

Air conditioning

• Keep air volume handled to a minimum
  
  
• Set the room cooling temp to 24° Celsius or above
  
  
• Rely upon air recirculation where possible
  
  
• Keep all ducts, evaporators, condensers etc clean
  
  
• Change filters on a regular basis
  
  
• Don't heat and cool air at the same time
