DURATION 2016-2024
-
To develop a state-of-the-art energy centre which would avoid the need for each property to have an individual boiler, an efficient and environmentally friendly way to generate heat.
-
VZDV were invited to be involved in this prestigious because of our experience in district and community heating schemes.
-
The primary challenge of the project from a heat network point of view was to design the central plant and heat network to deal with the changing heat demand of a phased project over the best part of 10 years.
-
In this instance, it is beneficial to have an independent advisor like VZDV to provide a concept heat network design which enables developers to go to market and find the most appropriate solution in terms of cost, ownership, procurement, and ongoing operation and maintenance.
In proud collaboration with:
Mulalley and One Housing Group, and the London Borough of Enfield.
BACKGROUND
New Ladderswood LLP is a joint venture between developer Mulalley and housing association One Housing Group, working in collaboration with the London Borough of Enfield. This major regeneration development features:
93 social housing properties
56 shared ownership apartments
368 privately owned properties
517 properties in total (426 apartments and 81 houses)
There will also be:
6 commercial units
An 85-bedroom hotel
A new community centre
The energy strategy for this project is to provide all heating and hot water for the development from a district heat network. A state-of-the-art energy centre containing central plant to heat water and pump it through a network of insulated pipes to each property on the development. This avoids the need for each property to have an individual boiler and is an efficient, environmentally friendly way to generate heat.
THE OBJECTIVE
The objective is to liaise with all stakeholders involved in the project and to deliver a district heating network for all buildings on the site and make future provision for development on an adjacent site. The final objective being that the London Borough of Enfield and an energy supply company would take over the central plant and heat network for the ongoing operation and maintenance for the life of the development.
VZDV were invited to be involved in this prestigious because of our experience in district and community heating schemes.
THE CHALLENGE
The primary challenge of the project from a heat network point of view was to design the central plant and heat network to deal with the changing heat demand of a phased project over the best part of 10 years.
THE DEFINING MOMENT
VZDV developed a concept central plant energy centre and heat network design which in association with Mulalley and The London Borough of Enfield, was put to the market to find the best form of procurement. This allowed the stakeholders to compare the merits of different manufacturers, contractors and energy supply companies as to the best form of procurement, operation and maintenance of the heat network for the life of the development.
During this process, Enfield Council’s heat network company Energetik was established. The Arnos Grove heat network supplying the Ladderswood Estate was the first of Energetik’s heat networks to go into operation, therefore setting an important precedent for the level of quality and positive customer experience that Energetik wants to deliver across its schemes.
With Energetik coming on board, the Council agreed to revise the development agreement to incorporate as much of the requirements of Energetik’s technical specification as was economically viable. This included VZDV, Mulalley and One Housing Group providing an energy centre and network that could be expanded and act as a district heating hub in the Arnos Grove area, allowing it to connect other developments when economically viable.
THE TRANSFORMATION
The regeneration project is now well underway and the project is in the final phases of the project. The heat network is up and running and is adapting to the ever-increasing load demand as each new phase comes on line.
Other low zero carbon technologies such as photovoltaic panels and air source heat pumps supplement the design to ensure Code for Sustainable Homes ‘Level 4’ and BREEAM Excellent are achieved respectively for both the residential and commercial areas of the development.
Heat is supplied to the entire site from the Energy Centre via a steel district heating main which has been sized to accommodate all phases of the development and a number of future neighbouring sites. The main runs from the Energy Centre to the hotel located within Phase 2, equating to more than three kilometers of highly insulated buried pipework.
LEARNINGS
At the start of a development, it is often unclear what form of procurement or management of a heat network is best suited to a new development. In this instance, it is beneficial to have an independent advisor like VZDV to provide a concept heat network design which enables developers to go to market and find the most appropriate solution in terms of cost, ownership, procurement, and ongoing operation and maintenance.
NEXT STEPS
VZDV would like to collaborate with any local authorities, developers or main contractors on similar projects.
