JouleDHW

The Joule DHW complies with the new Part L of the building regulations. The carbon emissions factor for electricity has been reduced by 74% in comparison to previous levels. It now stands at 0.136kgCO2/kWh. This is the single biggest driver for heat pumps in new build dwellings. As can be seen in the carousel above, the future homes standards due to take effect in 2025 requires a new dwelling to have 75% less carbon emissions than that the notional dwelling. The Joule DHW can play an importantg part in achieving this. A decentralised solution like the Modulair has no requirement for a heat distribution network running throughout the development. This, in addition to the capital benefit, has a significantly positive impact on the overheating risk analysis of the building as can be determined by following the CIBSE TM59 methodology.

The Joule DHW is a suitable technology to achieve compliance with NZEB in new build apartment developments. The system will achieve these regulations with the addition of photovolvaic panels (PV) which is a key requirement for EU Taxonomy legislation, a European wide “Green” classification of buildings. This is critically important for companies to avail of low interest rate “Green” funding or additionally, to purchase, forward purchase or forward fund developments.

Separately to this the Joule DHW has a significant impact on the buildings performance in the commonly used Home Performance Index (HPI). A decentralised solution like the Joule DHW has no requirement for a heat distribution network running throughout the development. This, in addition to the capital benefit, has a significantly positive impact on the overheating risk analysis of the building as can be determined by following the CIBSE TM59 methodology.

The building sector represents 39% of Europe’s overall carbon emissions, 28% from operational emissions energy needed to heat, cool and power them, and the remaining 11% are from materials and construction. 

To reduce overall emissions, the sector must improve building energy performance, decrease building materials’ carbon footprint, multiply policy commitments alongside action and increase investment in energy efficiency. From a building services perspective there are some key metrics needed to comply with this, covered by local legislation. The Joule DHW range of DHW heat pumps increases energy efficiency, reducing both operational & embodied carbon levels.
