Community housing development, Bristol

We provided energy consultancy for a new community-led, part self-build development consisting of 50 new Passivhaus units in Bristol.

Community Housing Development

We developed the energy strategy, carrying out an environmental and economic study into centralised, communal and local heating and power options. This included reviewing district heating and microgrid power options.

Each house featured rooftop photovoltaic panels that fed into a shared battery storage system, creating a single point of commercial access to the grid, resulting in the opportunity to take advantage of off-peak prices. We developed heat pump options and carried out life cycle modelling to determine an optimised approach over a 30-year economic cycle, in line with the client's investment requirements.

A ground coupled borehole array heat pump provides low carbon heating and hot water to the development. Our Smart Energy team developed a cash flow model including revenue (heat sale and RHI payments) and costs to help maximise benefits to tenants and alleviate fuel poverty.

We also provided thermal and climate change modelling and building massing advice.
