Reduction of GHG in buildings: impact for HVAC design and industry

Following the “Paris agreement” on climate change and the EU “green deal”, the building and real estate industries have to integrate energy efficiency and GHG emissions in their decision process for new building but also for existing buildings retrofit strategy. It has a impact on HVAC design in order to select products based on life span expectancy, performance during this life cycle, GHG emissions weight for components production (factory and transport)… And of course, primary energy source and consumption linked to energy efficiency. A new set of the key European overarching standards on energy performance of buildings, namely EN ISO 52000-1, EN ISO 52003-1, EN ISO 52010-1, EN ISO 52016-1, and EN ISO 52018-1, and EN 17423 (see EPB Center | EPB Standards ) were developed in order to share transparency on calculation results based on indoor environmental quality (EN 16798-1)

Estonia – KredEx renovation grant programmes and ventilation requirements

Renovation grants for comprehensive renovation of apartment buildings have been available in Estonia since 2010. Around 700 apartment buildings were deeply renovated during first 2010-2014 period of Estonian KredEx renovation grant scheme. Evaluation of the results by comprehensive survey including field measurements and energy monitoring in renovated buildings showed many ventilation related problems. The grant system was developed so that more strict and detailed requirements were set for ventilation systems and the maximum grant was increased from 35% to 40% of the total construction cost of renovation project. These new requirements included room-based ventilation rates both for supply/intake and extract air, as well as heat recovery and preheating of intake air requirements. Model technical solutions were developed in the form of model design drawings and guidance to make it easier to follow new requirements including the installation of heat recovery and avoiding thermal bridges in insulation of the building envelope. During next period of 2015-2018 KredEx scheme invested 102 M€ to renovation. Follow up survey showed that apartment buildings were deeply renovated and well ventilated which has led to win-win-win situation. Economic analyses report that the grants given by the government are budget neutral, because of average tax return of 32% and additionally significant job creation that makes good contribution to Estonian economy. Homeowners benefit through improved indoor climate and general condition of the property and increased real estate value. From 2019 the renovation scheme has continued with the same technical conditions, but the grants were split to 30% support in large cities and to 40-50% support in periphery. To date, about 3 000 apartment buildings have been renovated, and it is planned to renovate all the rest of apartment buildings constructed before 2000, all together 14 000 buildings by 2050 according to Estonian long term renovation strategy.

Making the EPBD fit for 2030 and beyond

The Energy Performance of Buildings Directive is a key element of the EU’s Fit for 55 Policy Package which intends to agree a set of regulations and support programmes enabling the European Union to achieve its climate objective of reducing greenhouse gas emissions by 55% in 2030 compared to 1990. In December 2021, the European Commission published a proposal to revise the Energy Performance of Buildings Directive (EPBD).

The current proposal is including a broad list of policy measures to improve Europe’s building renovation ecosystem, including initiatives to improve building performance standards, planning, financing, information, and advisory tools. It also sets new standards for new buildings and launches an initiative to address the whole life cycle carbon impact of buildings and construction.

The EPBD is the key legislative tool to deeply renovate and fully decarbonise the building stock in a way that brings benefits to all citizens and takes action to reduce energy poverty. This presentation will give an overview of the proposed measures and the process to agree this regulation. A critical evaluation of the most important measures will highlight the potential impacts of the revised EPBD.
