ASHRAE 90.1-2025 Published 16 Jul 2026 — 105-Addenda Update Reshapes Commercial Building Energy Standard
ANSI/ASHRAE/IES Standard 90.1-2025 was formally released 16 Jul with 105 addenda; the 2025 SI Edition is a 480-page USD 198 document. Addenda e and i closed public review 2 Aug 2026 — Addendum e expands the scope to allow energy-use communication requirements; Addendum i clarifies §6.4.1.4 on independent test data and exempts embedded fans from FEI. Addenda M and N (operational carbon) are being carved out into a companion publication. ASHRAE 2026-27 President Sarah E. Maston emphasized the standard's '50+ year role' as building-industry tools evolve.
U.S. Energy Efficiency Reform Act 2026 Introduced — Could Reshape DOE HVAC Standard-Setting Process
Sen. Mike Lee (R-Utah), chair of the Senate Energy & Natural Resources Committee, introduced the Energy Efficiency Reform Act of 2026 on 6 Aug. The bill rewrites how the Department of Energy develops and reviews energy conservation standards for household and commercial products — including HVAC equipment under the SEER2/EER2 framework — and has drawn support from the American Gas Association and other fuel-neutrality advocates.
European Commission Formally Argues Against Romania's Coal-Closure Deferral Plan (7 Aug 2026) — PNRR Milestone 119a Cannot Be Renegotiated
On 7 Aug 2026, the European Commission issued an explicit, public, formal rebuttal of Romania's plan to defer the closure of coal-fired power plants beyond the original PNRR timeline. The Commission argues 'it is no longer possible to renegotiate the PNRR regarding decarbonization milestone 119a, as there is no more time for this.' Milestone 119a remained unchanged at the July 2026 review. **PNRR implementation ends 31 August 2026** — a hard cliff. Romania Insider simultaneously reports the Energy Ministry issued a new appeal to limit electricity consumption for households + companies + public institutions (6 Aug 2026); industrial-consumer load-shedding mechanism via Transelectrica now active.

EU Heatwave Round 3 — Southeast European Power Exchange Prices Breach EUR 700/MWh (7 Aug 2026); Plant Shutdowns Across 6 Countries
The August 2026 EU heatwave is now the third round (Round 1 = 26 Jul 2026 45 °C Spain; Round 2 = 2-3 Aug 2026 Paks nuclear shutdown; Round 3 = 6-7 Aug 2026 SE European exchange prices + multi-country plant shutdowns). Slovenian exchange BSP Southpool: EUR 717/MWh on 3 Aug 2026 between 20:00 and 20:15 — highest in SE Europe. Croatia also above EUR 700/MWh. Le Monde (7 Aug 2026): France, Italy, Poland, Hungary, Romania, Slovenia all forced to shut down power plants due to low water levels or excessively high water temperatures. EU Commission spokesperson 6 Aug 2026: 'the energy situation has been strained'; 'no immediate threat to security of supply.' Romanian government adopted mechanism allowing Transelectrica to limit power consumption for industrial customers.

Polish Data Center Plans to Send Waste Heat to Neighbours (7 Aug 2026) — First EU District-Heating-from-DC Project
A Polish data-center operator (7 Aug 2026) is planning to route waste heat from its server halls to neighbouring residential buildings via the local district-heating network — a first-of-kind EU signal on AI-data-center thermal-effluent monetisation. Aligns with EU heatwave-driven waste-heat + cooling-power demand spike + EU Energy Efficiency Directive (EED) recast Article 26 on waste-heat recovery + thermal-energy planning + EU Taxonomy Regulation (EU) 2020/852 climate-mitigation substantial-contribution criteria for waste-heat recovery in district heating/cooling + ISO 13612-1 + EN 13941 + EN 15316-4-3. The signal value: AI data-center cooling is no longer a pure waste-heat disposal problem — it can be a heat-recovery asset class if integrated with district-heating.

Data Center Liquid Cooling Market Projected to Reach USD 23.24 bn by 2035 (7 Aug 2026)
The global Data Center Liquid Cooling market is projected to reach USD 23.24 bn by 2035 according to a DataM Intelligence report released 7 Aug 2026. Market growth is driven by gigawatt-scale AI data-center campuses requiring liquid-cooling at the rack and chip level. Competing technologies include direct-to-chip, immersion, and rear-door heat exchangers. Dielectric fluids + glycol-water mixtures + 3M Novec engineered fluids are the three chemistry camps.

AI Data Centers Overheating — Semiconductor, Cooling, Power Industries Battle Thermal Runaway (7 Aug 2026)
On 4 Aug 2026, TrendForce confirmed Nvidia has begun reviewing lower-spec alternatives to the 12-high HBM4E (originally the baseline specification for Rubin Ultra from 2025 through H1 2026). DRAM supply shortage extending into 2027. Uncertainty surrounding validation and yield timelines for 12-high HBM4E. Nvidia halved SOCAMM capacity of next-generation Vera Rubin superchip due to LPDDR5X supply constraints. Server companies reduced RDIMM capacity in H1 2026 — memory supply crunch spreading across AI semiconductor specifications. FMS 2026 (Santa Clara): Samsung + SK Hynix unveiled next-gen memory technologies; CXL (Compute Express Link) = next-gen HBM, organically connecting CPUs/GPUs/memory to expand bandwidth and capacity.

Texas Governor Abbott Pauses All Data-Center Approvals for Statewide PUCT/ERCOT Audit (3 Aug 2026) — Stops Short of Ban
Texas Governor Greg Abbott on 3 Aug 2026 directed the Public Utility Commission of Texas (PUCT) and the Electric Reliability Council of Texas (ERCOT) to pause approvals of any pending data centers while PUCT/ERCOT conduct an audit of every data center advancing through ERCOT's interconnection process. ERCOT postponed its 'Batch Zero' system-wide review; will not issue the project classifications previously scheduled for 7 Aug 2026, instead seeking a good-cause exception from PUCT at the 20 Aug 2026 commission meeting.
