Energy Retrofit in European Building Portfolios: A Review of Five Key Aspects

2020

The research about energy efficiency in buildings has exponentially increased during the last few years. Nevertheless, both research and practice still cannot rely on complete methodologies tailored for building portfolios as a whole, because the attention has always been drawn to individual premises. Yet, energy efficiency analyses need to go beyond the single building perspective and incorporate strategic district approaches to optimize the retrofit investment. For this purpose, several aspects should be considered simultaneously, and new methodologies should also be promoted. Therefore, this paper aims to discuss energy retrofit campaigns in building portfolios, drawing an exhaustive and updated review about the challenge of jumping from the single-building perspective to a stock-based analysis. This research discusses the publications available on the topic from five key aspects that are all essential steps in achieving a complete and reliable study of energy efficiency at a portfolio level. They are energy modelling and assessment, energy retrofit design, decision-making criteria assessment, optimal allocation of (financial) resources and risk valuation. This review, therefore, advocates for joint consideration of the problem as a basis on which to structure further disciplinary developments. Research gaps are highlighted, and new directions for future research are suggested.

“…In the first phase, a survey of the most common building products with a high recycled content commonly used in building renovations was carried out in order to provide recommendations for the following design steps. For each selected product, the environmental sustainability and economic costs were investigated on the bases of a semi-quantitative evaluation matrix, which took into account the following four categories (Pittau et al 2017…”

This work brings together some recent research and results activities aiming at investigating the environmental benefits of using bio-based materials for the construction and refurbishment of residential buildings. The positive environmental effects of wood and other biogenic materials replacing other, more important, conventional ones, analysed through the application of Life Cycle Assessment methods, are here reported. Moreover, the investigated strategies for Carbon Capture and Storage (CCS) are here discussed, to evaluate the potential of carbon uptake of fast-growing biogenic materials when used as insulation systems. The results show the effectiveness of bio-based materials in contributing to the mitigation strategies of the impacts due to climate change.

“…Envelope technology research underway in the EU includes a variety of explorations, methods and applications for exterior envelope retrofits. For example, pre-fabricated rigid foam panels for multi-family building investigate in Italy have shown potential to reduce building energy demand by as much as 82% (Pittau et al 2017). The Multifunctional Energy Efficient Façade System for Building Retrofitting (MEEFS) was a program was an EU funded program from 2012-2016, with was a large collaboration between nine EU countries.…”

In the United States, 39% of total energy is consumed by the building sector, 20% of the total is attributed to residential buildings (U.S. Energy Information Administration, 2018). New, highperformance homes incorporate a combination of tight building envelopes, mechanical ventilation, and efficient components to ensure comfort, adequate airflow, and moisture control. These systems work together to create energy efficient homes that use measures to manage moisture, comfort, energy efficiency, and the indoor environment. Older homes, built before 1992 when the U.S. Department of Energy's Building Energy Codes Program was established represent approximately 68% of residential building stock in the country and often have significant air leakage and inadequate insulation. Homes with little to no air sealing or insulation have heating and cooling losses that can represent a substantial portion of utility bills. Done correctly, deep energy retrofits can significantly improve the energy performance of a home's thermal envelope, and increase homeowner comfort and health. This literature review summarizes current practices for exterior wall retrofits for existing homes, provides an overview of techno-economic approaches to investigating residential wall systems, and discusses thermal and hygrothermal modeling strategies. This literature review is part of a larger effort to identify state-of-the-art technologies for energy efficient wall retrofit systems that are suitable for cold and very cold climate zones. Retrofit wall systems that can be applied over existing siding offer a possible approach to reducing installation costs.
