SIERA for US Portfolios: Tech Backed by Trusted Advisors 

Juggling sustainability single-handedly is tricky enough; keeping every asset manager, advisor, and investor on the same page turns the job into plate-spinning at rush hour. One spreadsheet keeps track of New York’s emissions caps, another feeds Denver’s benchmarking portal, and a third travels to the European office so the numbers match the group dashboard.  

You scramble to fill cells, check formulas, and chase colleagues for missing numbers, and once “Sustainability-Report–FINAL-VERSION-copy.xls” is sent to the board you notice cell FF346 throwing a REF error.  

The pain is real.  

The answer isn’t another workbook – it’s a single home for US data that links state filings, investor scorecards, and a risk module tuned to local hazards.  

The US-sized Pressure Cooker 

Renewable Portfolio Standards, Clean Energy Standards, local Building Codes and Emissions Caps – a dozen states and cities now want asset-level data on energy, water, and carbon, each on its own deadline, uploads, and metrics. Miss one and fines climb like compound interest.  

While that chaos unfolds, federal support for ENERGY STAR wobbles on the political seesaw as Washington keeps hinting at cuts. If ENERGY STAR goes dark, do you have a back-up? 

Late-night compliance checks and back-to-back stakeholder calls leave one nagging question each quarter: when will the workload snap? Without a platform that grows alongside the portfolio, that moment probably isn’t far off. 

The problem is that few tools on the market are built to handle the quick turnarounds the market is throwing. Keeping up with evolving standards is a moving target. Reporting tools must be agile enough to incorporate new requirements on the fly. 

With the right platform, and a set of trusted advisors, conversations shift from “Who owns this file?” to “How do we cut exposure before quarter-end?” – and the lone sustainability lead gains a critical friend instead of another late-night task list. 

A Platform Built for US Compliance 

SIERA lets you shift the work into a single, cloud-based home that speaks the same languages as city portals, investor questionnaires and GRESB reports. Meter readings flow straight from utilities, emission factors and conversion tables update quietly in the background, and every data point is fully traceable, so you know what value originated from where and when it was created.  

With SIERA, you have full insight into the data generated in your buildings, and you own the access to it – now, and in the future. Should government ever shut down ENERGY STAR Portfolio Manager, nothing vanishes from your portfolio view in SIERA. Scores and raw numbers sit safely on our servers, ready for the next reporting period.  

And as portfolios move beyond domestic borders, the same platform can follow seamlessly. If your company manages assets across both sides of the pond, SIERA helps you collaborate with ease.  

But most importantly, SIERA comes with easy access to EVORA’s team of sustainability professionals who can act both as experts on matters that your team can’t prioritize, as well as an extra pair of eyes on what you’re already doing. 

 Extend Your Team Without Adding Headcount  

Real assets have unique sustainability challenges. They are tangible, long-term investments with diverse stakeholders. Regulations like those from the SEC, and frameworks like GRESB, are often specifically tailored to these assets, and the details can get pretty technical. For instance, calculating a GRESB Resilience score might require specialized knowledge. Without in-house expertise, investors could misinterpret requirements or miss opportunities to showcase positive performance. 

But most importantly, sustainability is a fast-moving field. What was best practice five years ago might be baseline today. New disclosure mandates are emerging, and frameworks change. Our clients often ask, “What’s coming next, and how do we stay ahead?”. This is where ongoing expertise is invaluable – having someone who keeps a pulse on regulatory changes and industry trends means you won’t be caught off guard.  

EVORA’s Collaborative Expertise is not just a mix of services. It’s a way of working that pulls together the right experts at the right time – advisory consultants, strategic specialists, and technical teams – to solve sustainability challenges that, at first glance, look impossible.  

From shaping a sustainability strategy review with clear milestones to turning raw utility feeds into live numbers inside SIERA, the team handles the entire data cycle: GRESB submissions, ENERGY STAR Portfolio Manager sync, and local reporting and benchmarking, all land on time. PRI, INREV, and quarterly reports draw from the same source of truth, keeping figures aligned across regions; tenant engagement surveys, annual award entries, and green building certifications build the story behind those numbers; acquisition due diligence flags risks before signing; and a top-down net-zero roadmap backed by physical climate risk guidance keeps the long-term target on track. 

You get the results you need – without burning out or inflating payroll.

Competitors may offer strong software or sharp consultants, yet rarely both under one roof. Combining the two means questions meet answers faster, risks surface earlier and capital stays protected. 

With GRESB raising the bar and local ordinances tightening their grip, the safest move is to put data, reporting and risk scoring on the rails now, rather than wage another battle with a monster spreadsheet next quarter.
