BER and Heat Pumps

Heat Pumps are in the list of Renewable Energy Systems and Sustainable Energy
systems recommended for the class of buildings categorized as large in SI 666.
A large building for the purpose of implementing these regulations and for the purpose of issuing
BER certificate has been defined as any building having over 1000m2 of usable area.

Heat Pumps
Heat Pumps are excellent devices for the harnessing of thermal energy in the environment (specifically the out door air).
A heat pump is an air conditioner which incorporates both;

• Cooling and dehumidification

and,

• Heating of a space.

The cooling and dehumidification here refers to comfort cooling in the warmer summer.
The heating will take place during the winter and other colder periods of the year.

A heat Pump in its simplest form comprises of;

• Compressor - a compressing and  pumping device for the refrigerant  (gas)
• Condenser - A heat exchanger coil meant to carry the hot refrigerant and dissipate that heat to the environment.
• A throttling device – a Capillary tube or an Expansion valve which separates and maintain high and low temperatures immediately
  before the cooling coil (evaporator) while regulating the Refrigerant flow.
• The Evaporator – heat Exchanger coils which extracts the room heat and transfer it to the refrigerant (which in the process takes a gaseous form).
• A  4 port  valve -  which  can reverse the direction of fluid flow from two tubes to the another two
• A System of copper tubes interconnecting all the components.
• An Electrical Power supply to the compressor and a control system with its switches and cabling.

Our BER Assessors
We employ Building Energy Rating (BER) assessors registered by Sustainable Energy Ireland (SEI), who carry out
BER assessments on  existing and new houses, single or in developments.

Our assessor will assess the dimensions, fabric, ventilation, water heating and lighting systems in your building.  
This will then be used to calculate an energy rating for the house. Energy ratings go from A to G, A being the most
energy efficient and G being the least energy efficient.
