ESTABLISHED HEATING & COOLING TECHNOLOGIES
FOR INNOVATIVE SYSTEMIC RETROFITTING

BuildHEAT systemic renovation approaches will make highly reliable packages available, the effectiveness of which in terms of energy performance and indoor comfort can be easily predicted during the initial decision- making phases.

The systemic renovation packages will exploit opportunities offered in terms of RES availability at building level (i.e. aero-thermal and solar energy) to match construction standards and building loads. Attention will be paid to the final energy consumption, which is related to the users’ annually incurred cost, to the primary energy, which is related to the overall environmental impact, and to the costs.

solution-ico1

Solution 1

Integration of a heat pump plus solar thermal system with thermal energy storages located in each single dwelling.

Benefits: total storage capacity increase, thermal losses reduction and energy use control and monitor.

solution-ico2

Solution 2

Mechanical ventilation with air-to-air heat pump that serves a single dwelling with a dedicated small PV field, equipped with a tank for the storage of domestic hot water.

Benefits: autonomous renewable electricity self-consumption and optimisation of DHW generation and ventilation, based on dwelling needs. Energy use control and monitor.

solution-ico3

Solution 3

ICT infrastructure connecting and monitoring all the decentralised units (for both solutions 1 and 2).

Benefits: optimisation of energy use and distribution, guaranteed and established through communications from single dwellings to building managers.

solution-ico4

Solution 4

Flexible solution of a multifunctional façade including insulation and active elements.

Benefits: easy installation of insulation, cladding and active elements like solar thermal collectors, PV panels, pipelines, air-ducts and electric cables.

Systemic retrofit packaging criteria

  1. High-energy performance, comfort and healthiness
  2. Not intrusive and easy installation
  3. Scalability from dwelling to district level in terms of energy management and financing
  4. Bankability

Innovative financial mechanisms will be designed during the project, exploring investment synergies among private and public funds. BuildHEAT proposes a risk mitigation approach generating value for investors: the aggregation of consumers and buildings into clusters or districts creates local ecosystems that are attractive for investors.
