“…Retrofit of residential buildings with BIPV has been recently addressed by Evola and Margan [26], with a solution of façade with PV modules combined with ceramic panels. In addition, Eicker et al [27] and Hachem et al [28] studied the convenience of the integration of PV modules in the retrofit of residential buildings in Northern Europe and Canada, respectively.…”

Building retrofit offers the opportunity to reduce energy consumption, improve energy efficiency and increase the use of renewable energy sources. The photovoltaic (PV) technology can be integrated into the building envelope, where conventional construction materials can be easily substituted by PV modules. Prices are competitive with some other solutions and good architectural building integrated photovoltaics (BIPV) solutions enhance the appearance of the buildings. All this makes BIPV an attractive solution for effectively and sustainably retrofitting building envelopes, providing savings in materials and in conventional electricity consumption and, at the same time, improving the energy efficiency of the buildings. This paper shows a building retrofit case study in which standard PV modules are integrated into a new ventilated façade, aiming at serving as an easy-to-implement example for large-scale actions.

“…Guillén et al [12] also study the thermal performance of several differently ventilated external walls, along a 24h period, with the aim of, among others, reducing the cooling needs of buildings in summer without increasing the total mass of the façade. Eicker et al [13] present an energetic and economic comparison between energy efficient refurbishment of the building envelope and the integration of renewable solar energy technologies for different climatic conditions. Ahern et al [14] implement a statistical study on the thermal transmittance values of the building envelope corresponding to the 32% of the total Irish dwelling stock, in order to use this data for different purposes, such as energy performance certification or as a key input to national building energy consumption models.…”

This paper deals with the minimization of a building's external wall thermal transmittance, with the aim of improving the energy efficiency of the building. The wall's thermal transmittance must abide by the current legislation, but also suit the limitations of other construction parameters, mainly budget and thickness, but also time limit, workforce, number and thickness of the layers and availability of materials depending on the approach. The optimization is achieved formulating an Integer Linear Programming (ILP) problem involving the parameters mentioned above. Therefore, any available ILP solver can be run to obtain the best combination of the different materials and thicknesses for the layers, in order to minimize the thermal transmittance. This paper presents a case study of a common but representative external wall consisting of 6 layers, with more than 670,000 possible combinations of materials and their thicknesses. The study concludes with a comparison of the lowest thermal transmittance obtained for a selection of budget and thickness combinations for the mentioned wall.

“…Lopez and Frontini [27] conducted a historic building retrofitting project incorporating solar photovoltaics (PV) and a solar thermal system to improve energy performance and the level of comfort for 3 buildings in Switzerland. Eicker et al [28,29] performed a cost effectiveness analysis of 3 demo buildings in Italy, Portugal and the UK. The economic benefits and the primary energy consumption for various configurations of two renewable technoogies (solar PV and solar thermal collectors) were investigated parametrically.…”

This paper presents a multi-criteria assessment approach for a wide range of energy efficient measures and their combinations applied for a residential building retrofit in Norway.A number of passive, active and renewable energy efficient measures (EEMs) have been selected and defined. Based on the level of energy saving potentials, these EEMs have been combined into 18 retrofit combination packages (COMBs) and grouped into various retrofit levels (Moderate Retrofit-I, II, III and Extensive Retrofit). The annual primary energy consumptions (heating, hot water and electricity) for the proposed combination packages were simulated in IESVE building energy simulation software. This is then followed by two levels of assessments: i) the comprehensive assessments of the key retrofit priorities including primary energy reduction, global costs, payback period and the carbon emission reduction and ii) social assessment with the aim to represent various stakeholders' views on the selected COMBs using a metric of weighting factors. Based on this, a multi-criteria assessment approach featuring a novel ranking factor (EEES) taking into account of energy, economic, environmental and social aspects during retrofit process was adopted. This approach quantifies different stakeholders' perspectives on the proposed COMBs, which could enable various stakeholders' involvement in the retrofit decision making process. It was concluded that COMB 05 and 06, which include only 2-3 passive and active EEMs have been ranked and chosen as the most favourable retrofit solutions, with EEES value equalled to 25.6 from various stakeholders' perspectives. The impacts of changing renewable energy prices and PV generated feed-in tariff rates on the global costs, carbon reductions and primary energy consumptions of the proposed COMBs, which have rarely been analysed in literature, are numerically investigated in this research. Such renewable EEMs which are greatly recommended by the European Commission, are expected to gain further support from national level government renewable incentives. Therefore, it is envisaged that in the long term, Extensive Retrofits incorporating mostly renewable EEMs could become more affordable and cost effective.
