Climate neutrality of buildings - Net Zero

JW+A provides specialized services in consulting and conducting climate neutrality analyses of buildings called Net Zero for commercial properties.

Net Zero is a term that refers to the energy efficiency of buildings with a zero carbon footprint. It is a state in which the carbon dioxide emitted by a building is completely offset. It can apply to the entire life cycle of a building – including the construction process.

Why is Net Zero necessary?

The Paris Agreement, to which Poland is a signatory, requires that net greenhouse gas emissions reach zero by 2050. The European Union, as part of the European Green Deal, aims to reduce greenhouse gas emissions by 55% by 2030. Achieving these goals will be possible through the decarbonization of the building sector, which is responsible for 38% of global CO2 emissions.

Reducing the carbon footprint of buildings requires the involvement and cooperation of a wide range of stakeholders, from government administration to developers, investors, building owners, designers, architects and construction engineers.

To this end, the European Union has introduced tools to measure and improve energy efficiency, such as Taxonomy, “Fit for 55” or CRREM.

“Fit for 55” is a package of legislation relating to the EU’s new interim CO2 reduction target for 2030. This target has been increased – from 40% to 55% relative to 1990.

The Carbon Risk Real Estate Monitor (CRREM) defines decarbonization pathways for the commercial and residential real estate sectors to manage transition risk and align with the Paris Agreement goals. Therefore, it can be used to meet ESG or Taxonomy requirements.

Recent years indicate the emergence of a trend for investors to obtain additional information from companies related to ESG factors. In the investment process, non-financial data reporting is starting to become an increasingly important decision-making aspect.

What buildings can receive carbon neutrality certification?

Both planned and existing buildings can receive carbon neutrality certification. The Net Zero certification can be obtained after a minimum of one year’s use of the building, analyzing the consumption and amount of energy produced in that year. In order to achieve the target level, it is necessary to take care of energy efficiency already at the stage of designing a building.

Actions at the design and construction stage

Some Net Zero standards for designed buildings assume carbon neutrality throughout the life cycle of the building, including balancing the carbon footprint associated with the construction process. Therefore, we advise our clients which scope in the life cycle of the building we subject to a carbon neutrality analysis. Based on this, specialized specialists determine a strategy for responding to the requirements that are simultaneously set by Taxonomy and ESG.

Already in the construction phase, our design team provides specific guidelines, leading to improved energy efficiency of the building and reduction of related costs. Advanced simulation software allows to predict future parameters and indicators of the building such as utility consumption or CO2 emission.

For existing buildings

In order to prepare the most accurate strategy for an existing building, we conduct a preliminary energy analysis of the building. This allows us to define the energy efficiency indicators in relation to Net Zero and specifies which elements will be key in achieving the desired effect.

We support the client in deciding which of the proposed recommendations are most beneficial to implement. JW+A specialists simulate the calibrated energy model of the facility, based on real data. On the basis of this simulation the impact of the solution on the future operating costs is shown. Investment costs and payback time are calculated. On this basis, the customer can decide which of the proposed modernization options is profitable for him.

How do you get carbon neutrality confirmed for a building?

JW+A specialists

The JW+A specialists help you to achieve carbon neutrality certification for your building in every phase of the life cycle of your facility. In order to meet these criteria, requirements must be implemented that describe the specific technical solutions or the management of the design and construction process.

Preliminary project evaluation – experts analyze the building’s technical data to develop specific guidelines, leading to energy efficiency improvements and cost reductions.

Simulation and analysis – JW+A specialists use simulation software in this phase to predict, for example, how much energy the building will consume in the future. Further analysis of the building allows to assess the validity and influence of individual changes to increase the energy efficiency of the building.

Confirmation of the building’s carbon neutrality – after one year, the building’s energy consumption data is collected again. Based on this data, an energy audit report is prepared. Excess CO2 values are offset through the purchase of Green Certificates or Carbon Offsets. The final step is to perform an audit to verify the operation of the facility and compare the results to the simulation assumptions. Recommendations for the operation of the facility are also given.

In order to optimally and efficiently obtain confirmation of the carbon neutrality of an existing building – cooperation with the JW+A team consists of several basic steps.

Preliminary project evaluation – in this phase, a preliminary energy analysis of the building is carried out in order to define the energy efficiency indicators. This allows an accurate verification of the energy consumption and indicates which elements are worth paying special attention to.

Energy audit – the next stage is the energy audit. The most important element of the audit is the inspection of the building, during which a detailed conversation with the technical staff and building manager is conducted.

Decision-making support – the final stage is to support the client in deciding which of the recommended recommendations carry the greatest benefit for them.
