Step 1: Fabric 1st Approach:
You should always aim to insulate the envelope of a home first through roof, wall and floor insulation, windows and doors. This approach will improve airtightness and benefit the comfort levels in a home and reduce heating requirements. The cheapest energy is the energy you don’t use!
Step 2:Air Permeability
An air permeability of 5m3/h.m2 at 50pa or less is desirable to achieve a high performing home suitable for heat pump installation. Along with this level of airtightness a clear ventilation strategy shall be required and can generally be achieved through a DCV (Demand Control ventilation) CMEV (Centralised Continuous Mechanical Extract Ventilation) or MVHR (Mechanical Ventilation Heat Recovery) system.
Step 3: Heat Pump
The heating centre of a home should be through a heat pump to avoid using fossil fuels and future proof the home for the greening of the national grid by 2030.
Step 4: Renewal Energy
Install renewable energy source to provide renewable energy and meet Part L Building Reg. requirements.
Note: All works should be designed by a competent designer (technical assessor) and fitted in accordance with current building regulations.
Note : Costs are outlined to provide a guide on upgrading each property type to A-rating with heat pump installation; VAT is included; excludes any grants or energy credits avaliable; not all upgrade measures are suitable or required to an individual property; each house type should be reviewed and specified individually, etc
