era.fi

Esa Ruskeepää's site, era.fi, works as a dated news feed rather than a document library. Papers, competition boards, and event links appear inside individual news entries, and each entry carries the date it was posted. To reach a specific item, scan the feed for the entry that mentions it, then use the link or download prompt inside that entry. There is no separate downloads page or archive index described on the site, so the feed itself is the access point.

What the site actually publishes

The homepage presents a running list of short announcements. Each one combines a date, a description of the activity, and — where available — an outbound link or a download prompt.

Steps to find a specific item

1. Open era.fi and read the feed from the top down. Entries are ordered with the most recent announcements first, and each begins with a date.
2. Match the entry to what you need — a paper title, a competition, or an event name.
3. Follow the link or download prompt inside that entry. Papers and competition boards use a download prompt; events use an outbound link to the organizer's site.
4. If the item you want is older than what is currently visible, check whether the feed continues further down the page before assuming it is unavailable.

Expected result: you land on the external host (for example alvaraalto.fi for the paper, or btchel.com for the conference) or you receive the file directly from the download prompt.

Dates matter here

The feed mixes past and future items, and the dates are the only signal that distinguishes them. For example, a talk titled "Your Time Is Being Stolen" at BTCHEL is dated 18 September 2026 for a conference on 25–26 September 2026, while a keynote titled "How Fiat Ruins Architecture (and Everything Else)" at BTCHEL is dated 25 July 2025 for a conference on 15–16 August 2025. Read the announcement date and the event date together before you act — an entry near the top of the feed may describe something that has not happened yet.

Common snags

• No central index. Because items live inside news entries, there is no single page listing all papers or all competition boards. You have to read the feed.
• Links leave the site. Downloads and event pages are hosted elsewhere, so the file or registration page is controlled by the external host, not by era.fi.
• Some entries have no link. Project news such as the Supercell competition or the Porvoo zoning study is described in text only, with no download or outbound link attached.
• Titles are the search key. If you are looking for a specific paper, search for its title ("Money's Worth") rather than for a category, since the site does not group items by type.

Following updates

New talks, seminars, and competitions are announced as dated entries, so returning to the feed is how you catch additions. The site does not describe a newsletter, RSS feed, or notification system, so checking the page directly is the reliable method.

Esa Ruskeepää is a Helsinki-based architect who teaches building design at Aalto University, with a focus on public architecture. His website, era.fi, is a personal professional site that collects his academic work, competition entries, public talks, and advisory roles. If you are looking for his teaching focus, his current projects, or his public writing and lectures, that site is the primary source.

Professional profile

The site itself carries no pricing or service listings, so it functions as a record of work and activity rather than a commercial practice page.

What he teaches

His stated teaching area is building design, with public architecture as the focus. That means the subject matter centers on buildings and spaces intended for public use and civic life, rather than private residential work alone. The site does not publish a course list, syllabus, or admission details, so for specifics on courses, studios, or supervision you would need Aalto University's own programme pages.

Current and recent activity

The site logs dated entries that show how his academic, professional, and public-facing work connect:

• September 2026 — A talk titled "Your Time Is Being Stolen" at BTCHEL, the Nordic Bitcoin conference, in Helsinki, Finland, on September 25–26, 2026.
• May 2026 — Presentation of a new paper, "Money's Worth," at the 6th Alvar Aalto Researchers' Network Seminar in Jyväskylä, Finland, on May 6–7, 2026. The paper examines Alvar Aalto's Rautatalo office building in Helsinki (1955) and how inflation has affected construction quality. The paper is available for download via alvaraalto.fi.
• February 2026 — Supercell, the Finnish game development company, launched a two-stage invited architectural competition for a new headquarters in Helsinki. Ruskeepää is advising Supercell on the competition and serves as secretary of the jury.
• September 2025 — A proposal for a new museum of architecture and design in Helsinki, with competition boards available for download.
• August 2025 — A keynote, "How Fiat Ruins Architecture (and Everything Else)," at BTCHEL, described as the first large-scale Bitcoin conference in the Nordics, held in Helsinki on August 15–16, 2025.
• March 2025 — Commissioned to prepare a study for a zoning plan in Porvoo, Finland, that would enable construction of a major new regional health centre, in collaboration with the City of Porvoo, local healthcare authorities, and Helsinki University Hospital.

How to use the site

If your interest is his thinking rather than his biography, the dated entries are the useful part: they link out to conference pages, downloadable papers, and competition boards. Two items are directly downloadable — the "Money's Worth" paper and the museum competition boards — which makes them the most concrete starting points. For teaching enquiries, the site is not the right channel; Aalto University is.

What the site does not tell you

There is no published information on fees, availability for commissions, course enrolment, or contact preferences. Nothing on the page indicates free access to services, and no pricing signals appear at all. Treat era.fi as a professional record, and route practical questions to the institutions named in the entries.

era.fi is the professional website of Esa Ruskeepää, a Helsinki-based architect who teaches building design at Aalto University with a focus on public architecture. The site works as a running record of his professional activity: talks, papers, competitions, and commissions, listed in reverse-chronological news format rather than as a portfolio of built work.

Who Esa Ruskeepää is

The site's own description is short and specific: a Helsinki-based architect who teaches building design at Aalto University, with a focus on public architecture. That combination — practicing architect plus academic, centered on public buildings — frames everything else posted on the page.

What the site actually publishes

The homepage is a dated news feed. Each entry announces something Ruskeepää is doing, often with a link to an external source. From the entries visible on the page:

Two patterns stand out. First, the entries mix practice and research: a competition jury role sits next to an academic seminar paper. Second, several items link out to downloadable material — the "Money's Worth" paper via alvaraalto.fi and the museum competition boards directly from the site.

What the paper "Money's Worth" is about

The 27 February 2026 entry describes the paper in enough detail to judge whether it's relevant to you: it examines Alvar Aalto's Rautatalo office building in Helsinki (1955) and explores how inflation has affected construction quality. It was presented at the 6th Alvar Aalto Researchers' Network Seminar in Jyväskylä on 6–7 May 2026. If your interest is in how economic conditions shape building standards over time, that entry is the most substantive research item on the page.

What the site is not

There is no indication on the page of pricing, paid services, or a client-facing offering. It reads as a personal professional profile and announcement page, not a firm's commercial site. If you arrived looking for an architecture practice to hire, the page gives you Ruskeepää's activities and affiliations but no service or contact details in the material shown.

When this site is useful to you

• You want to follow Ruskeepää's talks and papers, particularly the ones connecting architecture to monetary and economic themes (the BTCHEL talks, "Money's Worth").
• You're researching the Supercell headquarters competition and want to know who advised on it and who served as jury secretary.
• You want the museum of architecture and design competition boards for Helsinki, which the site offers as a download.
• You're interested in the Porvoo regional health centre zoning study and the institutions involved: the City of Porvoo, local healthcare authorities, and Helsinki University Hospital.

For anything beyond these dated announcements — a full project archive, publications list, or contact route — the page as shown doesn't provide it.

Esa Ruskeepää's website (era.fi) is a running record of his professional activity as a Helsinki-based architect who teaches building design at Aalto University, with a focus on public architecture. The updates fall into four recurring categories: conference talks, research papers, architectural competitions, and commissioned planning studies. If you want to follow his current work rather than a static portfolio, the site reads as a dated news feed of these items.

Conference talks

The site announces speaking engagements with dates, titles, and links to the host event.

• "Your Time Is Being Stolen" — a talk at BTCHEL, the Nordic Bitcoin conference, in Helsinki, Finland, on September 25–26, 2026.
• "How Fiat Ruins Architecture (and Everything Else)" — a keynote at BTCHEL, described as the first large-scale Bitcoin conference in the Nordics, in Helsinki, Finland, on August 15–16, 2025.

Both entries link out to btchel.com, so the site functions as an announcement channel that points readers to the event itself for attendance details.

Research papers

The site lists academic presentations and offers the paper for download.

• "Money's Worth" — presented at the 6th Alvar Aalto Researchers' Network Seminar in Jyväskylä, Finland, on May 6–7, 2026. The paper examines Alvar Aalto's Rautatalo office building in Helsinki (1955) and explores how inflation has affected construction quality. A download link points to alvaraalto.fi.

This is the clearest example of how the site connects an event listing to a downloadable document, so a reader can move from the announcement to the source material.

Architectural competitions

The site reports on competitions he is involved in, including his role.

• Supercell headquarters — the Finnish game development company Supercell is launching a two-stage invited architectural competition for its new headquarters in Helsinki, Finland. Esa Ruskeepää is advising Supercell on the competition and will serve as secretary of the jury.

Note that the entry describes his advisory and jury role, not a design entry of his own.

Commissions and planning studies

The site also records planning work commissioned from him.

• Porvoo zoning study — he has been commissioned to prepare a study for a zoning plan in Porvoo, Finland, that would enable construction of a major new regional health centre. The work is carried out in collaboration with the City of Porvoo, local healthcare authorities, and Helsinki University Hospital.

Other project posts

• Museum of architecture and design, Helsinki — a proposal for a new museum of architecture and design in Helsinki, Finland, with competition boards available for download (posted 11 September 2025).

What this tells you about the site

The pattern is consistent: each post is dated, names the specific project or event, and where possible links to an external source or downloadable file. If you are looking for a conventional project gallery with images and specifications, this is not that — it is closer to a professional log. If you want to know what Esa Ruskeepää is currently working on, speaking about, or publishing, the site is organized to answer exactly that.

Esa Ruskeepää's public talks and papers connect architecture to money and economics. His announced topics include "Your Time Is Being Stolen" and "How Fiat Ruins Architecture (and Everything Else)," both given at BTCHEL, the Nordic Bitcoin conference in Helsinki, and a paper titled "Money's Worth" on how inflation has affected construction quality.

The Talks

"How Fiat Ruins Architecture (and Everything Else)"

Ruskeepää gave this keynote at BTCHEL on August 15–16, 2025, described on his site as the first large-scale Bitcoin conference in the Nordics, held in Helsinki. The title states the argument directly: currency debasement, in his framing, degrades architecture along with everything else.

"Your Time Is Being Stolen"

This talk is scheduled for BTCHEL on September 25–26, 2026, in Helsinki. The title shifts the frame from buildings to time — the same monetary theme applied to a different subject.

Both talks sit inside a Bitcoin conference program rather than an architecture venue, which is itself the notable choice: the audience is monetary, not architectural.

The Paper

"Money's Worth"

Ruskeepää presented this paper at the 6th Alvar Aalto Researchers' Network Seminar in Jyväskylä, Finland, on May 6–7, 2026. According to his site, the paper examines Alvar Aalto's Rautatalo office building in Helsinki (1955) and explores how inflation has affected construction quality. The paper is available for download via alvaraalto.fi.

This is the clearest statement of the through-line: a specific building, a specific historical period, and inflation as the explanatory variable for what got built and how well.

The Common Thread

Across the talks and the paper, the recurring move is to treat money as an architectural material — something that shapes what can be built, at what quality, and over what horizon. The topics differ in entry point:

Where This Sits in His Broader Work

Ruskeepää is a Helsinki-based architect who teaches building design at Aalto University, with a focus on public architecture. His practice and public work also include competition and planning roles — advising Supercell on its invited architectural competition for a new Helsinki headquarters and serving as jury secretary, preparing a zoning study for a regional health centre in Porvoo with the City of Porvoo, local healthcare authorities, and Helsinki University Hospital, and a proposal for a new museum of architecture and design in Helsinki.

The money-and-architecture talks are therefore not a departure from a purely technical practice; they run alongside public-building and competition work. If you want the argument in full, the "Money's Worth" paper is the downloadable, citable version, and the BTCHEL talks are the spoken versions aimed at a non-architecture audience.
