Building retrofit has been an important method to reduce the great potential of energy consumption; however, considering the post-retrofit building performance of traditional energy efficient interventions, the issue of indoor air quality, such as humidity and sanitation, is often be complained by occupants. Therefore, humidity and temperature inde...
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 hav...
This paper presents a novel Energy Performance Certification (EPC) related holistic building retrofit approach for a Norwegian apartment block built in 1980s. Based on the pre-combination principles of “Fabric priority”, “Renewable in supplement”, “Avoid complicated installation”, 11 energy retrofit measures (ERMs) were defined and combined into 18...
The heat and mass transfer of liquid desiccant for dehumidification and cooling has been investigated in recent years as a promising energy-efficient technology to improve indoor thermal comfort. Limited studies, however, investigated integration strategies and energy performance of such systems in real buildings with performance correlations in bu...
To achieve carbon neutrality in the EU, it is important to renovate the existing EU residential buildings for a higher building energy efficiency. This study examines the impacts of several novel renovation technologies on energy consumption, CO2 emissions and indoor climates in southern European residential buildings through building-level simulat...
In Europe, 68% of residential building stocks are single-family houses, of which roughly 54% are constructed before the 1970 s with poor energy efficiency. However, few studies have addressed the issue of ‘Rapid and accurate energy-economic performance prediction of deep energy retrofit in single-family houses’ over the past decades. Recently, this...
Urban heat island (UHI) effects were first observed in London in the 19th century. The urban heat island is identified by developing higher temperatures in urban areas than the surrounding rural areas that directly surround them. However, there are some main mitigation strategies to deal with subtropical UHI, such as increasing the albedo of the ur...
This paper addresses the numerical and experimental performance analysis of a windows heat recovery system made of heat pipes. For modelling, the heat pipe is considered as a pseudo solid material with high value of effective thermal conductivity. An experimental investigation using a window heat recovery prototype was carried out to predict the va...
According to the EU Commission projection (2016/547/EU), the current average renovation rate is far below the expected rate of 3% to achieve carbon neutrality in building sectors by 2050. This is due to the fact that, during the building retrofit optimisation process, the decision-making criteria and objectives are generally optimised separately, a...
Energy requirements in urban areas are rising rapidly with the increase of the urban population. Cities consume the most energy globally with carbon dioxide emissions increased by more than 70% in city areas. Sustainable urban systems can reduce economic costs, decrease environmental influence, and improve human comfort. Besides, the urban heat isl...
In this conference, a speech given about the comparison between holistic electrification retrofit and deep energy retrofit for optimal decarbonisation pathways of UK dwellings, with demonstration of a case study for the 1940s’ British post-war.
An increasing interest rises in assessing building electrification pathways under the constraints of grid stability, costs, and carbon. Meanwhile, Deep Energy Retrofitting (DER) has been recognised as a pivotal strategy towards building decarbonisation, offering tremendous benefits in reducing energy consumption, tackling climate change, and enhanc...
A significant reduction potential in energy use and carbon emission in the EU can be achieved by following a primary strategy of upgrading the low energy-efficient existing European buildings. The decision about which combinations of retrofit measures should be selected in a particular dwelling is highly affected by the motivations of homeowners, w...
Building baseline energy simulation models are usually inaccurate validation with real-data measurements, failing to predict post-retrofit energy performance and a further selection of retrofit measures. This paper investigated a data-driven based validation and calibration approach with different input outdoor temperature sources to analyse its im...
This paper aims to evaluate the energy-saving potential, affordability and thermal comfort performance of various passive building retrofit measures for a historical building (late nineteenth-century Victorian house) renovation. Three types of interior passive retrofit measures (i.e. internal wall insulation, glazing upgrade and airtightness improv...
In this study, we have investigated a hybrid thin film PV vacuum glazing called: ‘PV VG-4L’. The glazing involves an integration between a thin film PV glazing with a double vacuum glazing (both manufactured independently), and an additional layer of self-cleaning coated glass which totalling four layers of glass. The mathematical model of the PV V...

The aim of Surefit is to demonstrate fast-track renovation (40% reduction in implementation time) of existing domestic buildings by integrating innovative, cost-effective, and environmentally-conscious prefabricated technologies. The project is about to reach the target of near zero energy through reducing heat losses through the building envelope and energy consumption by heating, cooling, ventilation and lighting, while increasing the share of renewable energy in buildings. This will be achieved through a systematic approach involving key stakeholders (building owners and users, manufacturers, product and services developers) in space heating, cooling, domestic hot water, lighting and power generation, as well as a demonstration phase in five representative buildings in different climates
