2 by 2050
Correction

Zurich’s official target is now 2,000 watts by 2040, not 2050.

Full reasoning

This table entry is outdated. The City of Zurich’s current official energy-policy monitoring page states: "Ziel: Reduktion auf 2000 Watt Primärenergie pro Einwohner*in bis 2040." Its 2000-Watt Society page likewise says that after the 2022 Net Zero decision, "Das Ziel von 2000 Watt Primärenergie pro Person und Jahr muss neu auch bis 2040 erreicht werden."

So the article’s Zurich row, which says "2 by 2050", no longer matches Zurich’s official target date. The current target year is 2040.

Claim
The Swiss Federal Office of Energy stipulates that the 2000-watt sites label is awarded to residential developments demonstrating sustainable practices in construction, operation, renovation, and mobility.
Correction

This is outdated: the 2000-Watt-Areal label was replaced and is no longer being certified.

Full reasoning

This statement is no longer correct in the present tense. The Swiss Federal Office of Energy announced in 2022 that the former 2000-Watt-Areal label was being replaced by Minergie-Areal and SNBS-Areal, and that the 2000-Watt-Areal product would no longer be offered or certified after 31 December 2023.

A 2026 Minergie article confirms the same point, stating that the certificate "seit Ende 2023 nicht mehr vergeben wird" (has no longer been issued since the end of 2023).

So readers are misled if they are told that the 2000-watt sites label is awarded now. It is a discontinued certification, with successor labels in use instead.

Claim
whose construction starts in 2022.
Correction

The Smart Living Lab building did not start construction in 2022; the start was postponed.

Full reasoning

Official project updates contradict the claim that construction starts in 2022.

EPFL’s 2022 Smart Living Lab annual report says plainly: "Construction work was scheduled to begin in 2022 but has been postponed." A later Smart Living Lab update states that the project’s journey to implementation ended in 2024, "paving the way for construction work to begin in 2025."

So the article’s statement that construction starts in 2022 is incorrect.
