Educational Kit – Innovations for the real world

Almost 27 % of the total energy consumption in Europe is spent on residential buildings. 

The need to reduce the energy consumption of the building sector is widely recognized. It can be achieved through deep retrofitting of the building stock combined with a radical reduction of the needs of the new buildings.

Discover here the industrialised energy solutions in residential building retrofitting developed within BuildHeat.

D2.6 – Publishable report on HP + PV system performance

One of the BuildHeat objectives has been to develop cost-efficient heating and cooling solutions for the refurbished of multifamily houses. One of those solutions has been an air-to-air heat pump with integrated domestic hot water (DHW) production and storage as well as room ventilation, mainly powered with photovoltaic (PV) energy.

D2.10/A – Suitable centralized H&C layouts at building and district level

The design of a HVAC system of multiapartment buildings needs to tackle a range of needs including energy efficiency, installation cost, installation feasibility, comfort, building architecture, building regulations, systems monitoring and control typology, user/customer expectations.

D2.10/B – Suitable centralized H&C layouts at building and district level

This deliverable presents an advanced control technique for a complex heating, cooling and domestic hot water (DHW) system with solar thermal collectors for a residential building, which aims to achieve optimal and efficient energy use by exploiting hourly electricity tariffs, weather forecast and applying machine learning algorithms to identify typical occupant behaviour and the behaviour of the system.

D3.10/A – Publishable report on active façade kit

In the framework of systemic deep renovation, the building envelope becomes the principal key element in order to: (i) reduce heat losses and building external surfaces overheating, (ii) avoid overheating through proper solar radiation control, (iii) integrate solar panels such as PhotoVoltaic “PV” and Solar Thermal “ST” and (iv) facilitate the building services retrofitting exploiting the façade surfaces for non-indoor installations, for example integrating hot water piping or air ducts for the mechanical ventilation system.

D3.10/B – Circular economy principles for active façade systems

The proposed research aims at further developing the façade system technology according to the principles of Circular Economy and analyze alternative business models that could make the system more affordable from the sustainable point of view compared to the current linear scheme take-make-use-dispose.

The Circular Business Models will be analyzed in relation to the façade sector, highlighting drivers and barriers that could foster or hinder their development.

D4.3 – LCA-LCC study for technical results and demo cases

BuildHeat Project’s main goal is the elaboration of a systemic energy retrofit procedure for residential buildings. This procedure requires an in-depth assessment of energy and environmental implications of the decisions taken during the design, implementation and operation of the solutions proposed. Consequently, it has been performed a Life Cycle Assessment (LCA) and Life Cycle Cost Assessment (LCCA) in order to give decision-making support to designers, contractors and users.

D4.4 – Report on systemic retrofit packages, including performance, comfort and healthiness, and costs

The reduction of a building’s energy consumption can be pursued by intervening on both the envelope and HVAC system. Treating the building as a whole helps reducing the energy demand and consumption. An additional reduction in terms of fossil energy used can be achieved by exploiting renewable energy driven technologies as photovoltaic panels and solar thermal collectors.

D4.5 – Retrofit protocols

This document aims at reporting some renovation solutions involving envelope, HVAC system and renewable energy, applied to different residential buildings typologies located in different countries through Europe. For each solution, performance in terms of energy savings, use of renewables, environmental impact and operative costs is analysed.

D5.1 – Energy Audits of the Three Demo Cases

The objective of this deliverable is to report on the energy audits of the three demo cases of the project. This activity includes the collection of all relevant data of the three demo buildings regarding the characteristics of the building construction, Heating, Ventilation and Air Conditioning (HVAC) and lighting installed systems, energy uses, user behaviour and national legislation and incentives with the aim of making a comparison before and after the renovation process of the demo buildings.

D5.3 – Plans for the renovation of the demonstration buildings

The BuildHEAT project aims to develop innovative solutions for the energy retrofit of residential buildings. Systemic packages for facades and HVAC systems have been developed in the project and their effectiveness will be demonstrated in the Demo Cases (DC) in Rome (Italy), in Zaragoza (Spain), Salford (UK), three sites in Pinerolo (Italy) and Gleisdorf (Austria) involving more than 230 individual dwellings.

D6.1 – Report on construction sector

The first part of the document aims to provide an overview on the residential building stock in the EU-28. The aim is to describe the main features of the building stock, including information on the energy uses. The work is completed by a description of the market trends and investment behaviours/opportunities of the EU citizens. After a short overview of the overall situation in Europe, the document details the situation in the six most populous Member States.

D6.2 – Risk Management Plan for Investors (RMPI)

BuildHeat develops systematic retrofit packages to promote energy efficiency in residential buildings. At the same time, innovative financial models are required to gather the necessary monetary resources to support the renovation process and properly exploit the technological solutions developed. In this view, a key point is a deep understanding the risks for the possible financial schemes

D6.4 – Financing models for deep retrofit actions

This report illustrates the financing models for the deep energy retrofit of existing buildings. The refurbishment and the energy retrofitting of these buildings typically involve active and passive measures for reducing energy consumption and increase costs savings. However, an innovative deep retrofit like one in the BuildHeat project corresponds often to high investment costs which need to be financed exploiting many different options
