The DREEAM method is being demonstrated at three European regions in order to reflect the diversity and impact climate, cultural, and institutional differences have on the approach, and encourage replication of the approach across Europe.

Pilot site in United Kingdom (Whitegate Close, Padiham)
The Whitegate Close neighbourhood, owned by Places for People (PFP), is a mix of 109 properties in general need of upgrade. Heat is supplied to 23 properties by a natural gas fired high efficiency combi-boiler, and to 86 properties using legacy electrical storage heating. PFP currently have 30% of their present housing portfolio in electrically heated homes. All properties currently have an independent electrical grid connection and third party supplier contract.
PFP wants to increase the standard of energy services to their residents, reduce resident turnover, and make Whitegate a neighbourhood of choice. DREEAM is viewed as an opportunity to develop a low maintenance model for the UK social rented market and to find innovate ways to tackle the challenge of outdated and inefficient electric heating and hot water systems. PFP has a special interest in utilising integrated whole dwelling solutions that address all the aspects of the home that can be used to cut carbon emissions, including insulation, renewable heating systems, and control systems.
The main aim is to go beyond a business-as-usual renovation and demonstrate a new state of the art solution for the replacement old and inefficient all electric (heated) properties. Some ideas to accomplish this are: introduction of common electrical purchasing program for all PFP homes, installation of solar photovoltaic electricity supply, electric only homes, and installation of POD solar thermal and heat storage.
Pilot site in Italy (Viale Francia, Treviso)
Viale Francia, owned by ATER Treviso, is a 102 dwelling line-type building located within two towers of a six-tower complex at the outer edge of Treviso, in the district Borgo Furo. The current construction has no insulation, double glazed windows with ageing wood frames and PVC shutters. Space heating and DHW are produced by four centralised natural gas thermal plants (649kW, 463kW, and two 150kW). All properties currently have an independent electrical grid connection and third party supplier contract.
ATER Treviso wants to gain experience in energy consumption monitoring and ICT control to better understand actual return on investment and energy performance contract conditions. There is also a high desire to reduce energy consumption of the building portfolio of associated social houses.
The project aims to minimise power consumption through optimisation of the passive systems to minimise the active ones, geothermal optimal solutions to reduce the demand for electricity, and electricity production from renewable sources (photo-voltaic). Some ideas to accomplish this are: new terraces with building integrated photovoltaic coating, replacement of the thermal boilers with heat pumps and underground heat storage, and installation of roof mounted solar thermal system and storage.
Pilot site in Sweden (Koppargarden, Landskrona)
The Koppargården pilot site, owned by Landskronahem, is a 110 dwelling multi-family complex located in the north east of Landskrona. The building has an ageing brick façade, with minimum requirements for insulation and windows standards. Heat is supplied via a city scale local district heating system in cooperation with Landskrona Energy. All properties currently have an independent electrical grid connection and third party supplier contract. A BMS is installed in the complex that manages thermal heat availability based on outdoor temperature, and tenant thermostat settings.
Landskronahem wants to gain experience in integrated approaches to renovating their building stock, specifically the addition of renewable energy supply systems that support the district-heating network. There is further ambition to determine cost-optimal building envelopes that consider the unique technical set up of Landskronahem’s buildings.
The project collaborates with the district heating supplier Landskrona Energy, as part of the Green Hub local energy project. Some ideas to approach the multi-building renovation are: installation of close loop heat pump for waste-water heat recovery, additional insulation of culvert ducts between buildings, optimisation of primary heat production in central heating system, addition of photovoltaic renewable energy, installation of high efficiency lighting in communal area, and individual sub-metering of hot water use.
