The CCC’s June 2020 Emissions Progress Report
The Committee on Climate Change’s (CCC) most recent update on how the UK is progressing towards the achievement of emissions-based targets, such as net zero by 2050 and the carbon budgets, has certainly been listened to. There is no doubt that it influenced the Chancellor's recent Summer Economic Update and the decision to target a green recovery from the Covid-19 crisis.
So, what does the CCC see as the future of construction and what can be done to prepare for the changes this will make to HVAC specification?
We have summarised key industry insights in our 196-page report, structured by most commonly asked questions
Our report covers :
- How has lockdown affected the UK’s emissions progress?
- Has investment in low carbon solutions been shown to be commercially beneficial?
- Is the carbon tax scheme in London going to be applied to the whole of the UK? What does this mean for the development of upcoming regulation changes?
- Will Government address the cost difference between electricity and gas?
Our range of HVAC solutions aim to provide future proof technologies to building projects over various sectors.
How do ambient networks that use in-apartment heat pumps work?
Ambient networks typically consist of in-apartment water-to-water heat pumps connected via a central loop to a central plant. Each heat pump uses ambient water from the central loop to provide heating, hot water and even cooling into the apartment. For domestic hot water use, the heated water is stored in an unvented, integrated cylinder that sits below the heat pump module in the apartment, whilst the heating circuit could use emitters such as radiators, fan coils or underfloor arrays.
How do I know what capacity fan coil I need?
Working out what capacity fan coil unit you need requires a lot of factors to be taken into consideration from the outset of a project, including solar gains. These include building orientation, geographical location, envelope construction materials and infiltration alongside internal gains such as lighting, equipment and occupancy. These will have to be considered with any potential plans to install solar shading, as they all have an impact on the predicted performance of a building.
How to correctly size an ambient loop heat network using diversity factors
As their name suggests, ambient loops operate at significantly lower temperatures than traditional communal high temperature heating systems. This means that a different approach is required when sizing the ambient loop distribution system. Calculation of such systems follows a procedure where diversity is used to determine the design flowrate for a development. It also determines the sizing of pipework and circulation pumps for an ambient communal network solution such as the Zeroth Energy System. The in-apartment flowrates required for the selected size of the Zeroth Heat Pumps can then be calculated.
