Historic building restoration and renovation requires sensitivity to the cultural heritage, historic value, and sustainability (i.e., building physics, energy efficiency, and comfort) goals of the project. Energy-efficient ventilation such as demand-controlled ventilation and heat recovery ventilation can contribute to the aforementioned goals, if ventilation concepts and airflow distribution are planned and realized in a minimally invasive way. Compared to new buildings, the building physics of historic buildings are more complicated in terms of hygrothermal performance. In particular, if internal insulation is applied, dehumidification is needed for robust and risk-free future use, while maintaining the building’s cultural value. As each ventilation system has to be chosen and adapted individually to the specific building, the selection of the appropriate system type is not an easy task. For this reason, there is a need for a scientifically valid, systematic approach to pair appropriate ventilation system and airflow distribution solutions with historical buildings. This paper provides an overview of the interrelationships between heritage conservation and the need for ventilation in energy-efficient buildings, regarding building physics and indoor environmental quality. Furthermore, a systematic approach based on assessment criteria in terms of heritage significance of the building, building physics (hygrothermal performance), and building services (energy efficiency, indoor air quality, and comfort rating) according to the standard EN 16883:2017 are applied.

Environmental Quality Assessment

Michigan State University and the Michigan Department of Natural Resources established a partnership for sustainable park planning in October 2011. The purpose of the partnership was to enable students in the design fields to work on real-world projects and provide practical solutions. One of the notable projects was to assess old historic buildings in one state park and propose renovation plan to improve its indoor environmental quality and energy efficiency. The buildings in the park functioned as the traveler’s destination in the 1920s and still preserve original interior and exterior features. The team of undergraduates and faculty in interior design visited the park and assessed the interior and exterior conditions of two of its buildings. They used an assessment tool which was designed on a basis of the elements in the indoor environmental quality category (IEQ) of the US Green Building Council’s LEED. Results revealed that the indoor environmental conditions of the buildings should be improved. The energy efficiency of the buildings was low. Based on this assessment, this study offered practical suggestions for improving the building’s indoor environmental quality. This study also proposed an assessment tool for the historic buildings in the state parks in Michigan to assess current indoor environmental quality of those buildings.

Abstract Environmental sustainability certification represents a strategic opportunity for improving energy efficiency, environmental quality, rational use of resources and design innovation in historic buildings, allowing greater transparency on energy uses and environmental management. To address these aspects, the Green Building Council of Italy has developed a new rating system, GBC Historic Building®, derived from the most diffused environmental sustainability assessment method worldwide (i. e. Leadership in Energy and Environmental Design - LEED®), in order to evaluate the sustainability level of restoration, rehabilitation and adaptation of historic buildings built before the end of World War II. This manuscript focuses on how this innovative assessment method addresses energy issues and indoor environmental quality aspects throughout the different thematic areas, introducing the new category “Historic Value”, distinctive of this protocol, aimed at improving the knowledge on the historic building and to support a sustainable approach in the restoration process.

Current Case

The majority of kindergartens situated in the territory of former Yugoslavia need renovation. Apart from their enhanced energy efficiency, renovated buildings will presumably offer better indoor environmental quality. According to the current case study, children using a classroom with new windows installed are exposed to substantially poorer indoor air quality due to airtightness and improper ventilation, which calls attention to a vital technical issue of the current renovation process.

The One

Historic buildings still perform their role today by being utilized either for their original purpose or a new purpose for which they are adapted. These buildings have specific requirements that inhabitants must follow. These requirements and relating uses and maintenance procedures result from adaptive reuse decisions, which may not be the most optimal scenario. The imperative is that historic buildings are used in a manner that, on the one hand, does not endanger their value related to heritage and tradition, and on the other hand, guarantees a degree of utility for their inhabitants, such as acceptable performance with regards to either air cooling or heating. The challenge is how to optimize the use of energy for either air cooling or heating, provided that adaptive reuse decisions are grounded in certain very specific and very rigid principles. The latter render is extremely difficult to meet the twin challenges of ensuring energy efficiency and thermal comfort for inhabitants while at the same time complying with the adaptive reuse principles. To address this challenge and gain an insight into ways of navigating it, a Post Occupancy Evaluation (POE) is conducted in Former Soldier’s Residence in the Cairo Citadel, Cairo, Egypt, which is now used as the National Organization for Urban Harmony’s (NOUH) administrative head office, this research can be considered as a single domain from which many other possible multi-domains can be investigated while studying the case of adaptive reuse. Other aspects such as indoor environmental quality, air quality, acoustics and lighting might act as multiple approaches appear to be widely used according to this review study, and in the future, the authors intend to test this research with the current single approach used in this research, which is the thermal comfort. POE includes both objective and subjective assessment, the POE limitation at this research to those assessment while a multi-perceptional and behavioral factors might be used as physical, contextual, personal, and others. The simulation and the survey methods were employed consecutively to assess the case study. By considering the research results, it was determined that the building consumes unnecessary energy by its current use of air conditioning system.

The Impact

Within the framework of IEA-SHC Task 59, a multidisciplinary team of experts from around the world has come together to investigate current approaches for energy retrofit of the built heritage with energy efficiency conservation-compatible measures, in accordance with cultural and heritage values, and to check and adapt the new standard EN-16883:2017 for historic buildings. This paper introduces activities within IEA-SHC Task 59 (Subtask C) focused on retrofit solutions with high impact on sustainability, energy efficiency, and the integration of renewables, which is the main goal of the solar group, focused on the integrated solar systems for historic buildings. Relying on an extensive, detailed, and accurate collection of case studies of application of solar photovoltaic and thermal systems in historic buildings, the assessment criteria of the standard have been reviewed and tailored for better solar implementation evaluation in a heritage context. All this is studied based on technical compatibility, the heritage significance of the building and its settings, the economic viability, the energy performances and indoor environmental quality and use, as well as the impact on the outdoor environment of solar renewables.

The article analyses critera applying to the choice of energy efficient high quality light sources and luminaires, which are used in Russian domestic and international practice. It is found that national standards GOST P 54993–2012 and GOST P 54992– 2012 contain outdated criteria for determining indices and classes of energy efficiency of light sources and luminaires. They are taken from the 1998 EU Directive #98/11/EU “Electric lamps”, in which LED light sources and discharge lamps of high intensity were not included. A new Regulation of the European Union #874/2012/EU on energy labelling of electric lamps and luminaires, in which these light sources are taken into consideration, contains a new technique of determining classes of energy efficiency and new, higher classes are added. The article has carried out a comparison of calculations of the energy efficiency classes in accordance with GOST P 54993 and with Regulation #874/2012/EU, and it is found out that a calculation using GOST P 54993 gives underrated energy efficiency classes. This can lead to interdiction of export for certain light sources and luminaires, can discredit Russian domestic manufacturer light sources and does not correspond to the rules of the World Trade Organization (WTO).
