Daylight and Architectural Simulation of the Egebjerg School (Denmark): Sustainable Features of a New Type of Skylight
This article discusses the performance of a new skylight for standard classrooms at the
Egebjerg School (Denmark), which was built ca. 1970. This building underwent important reforms
under a European project to which the authors contributed. This research aimed to create a new
skylight prototype that is useful for several schools in the vicinity, since there is a lack of educational
facilities. The former skylights consisted of plastic pyramids that presented serious disadvantages
in terms of sustainability matters. During the design process, the priority changed to studying the
factors that correlate daylighting with energy and other environmental aspects in a holistic and
evocative approach. Accordingly, the new skylight features promote the admittance and di usion of
solar energy through adroit guidance systems. In order to simulate di erent scenarios, we employed
our own simulation tool, Diana X. This research-oriented software works with the e ects of direct
solar energy that are mostly avoided in conventional programs. By virtue of Lambert’s reciprocity
theorem, our procedure, which was based on innovative equations of radiative transfer, converts the
energy received by di usive surfaces into luminous exitance for all types of architectural elements.
Upon completion of the skylights, we recorded onsite measurements, which roughly coincided with
the simulation data. Thus, conditions throughout the year improved

The Complexity of Finding Small Triangulations of Convex 3-Polytopes
The problem of finding a triangulation of a convex three-dimensional polytope
with few tetrahedra is proved to be NP-hard. We discuss other related
complexity results.Comment: 37 pages. An earlier version containing the sketch of the proof

Conservation and modern architecture. Fortune and misfortune of the School of Mathematics at Rome University (G. Ponti, 1932-1935)
The framework of the Italian restoration doctrine is based on the reception and transmission of the
memory of the past. However, interventions in modern architecture represent a radical drift in the
sense that they mostly consist of reconstructions, refurbishments, and renovations. Such work
disregards the sense of value acknowledgment that is implicit in architectural conservation and
neglects the importance of material conservation. The un even fortune of the School of Mathematics
at Rome's University Campus illustrates this situation. This predicament is similar to that of many
other modern buildings that have been declared “monuments” by mouth but are actually bent to
listless and insensible use, mistreated, and hardly maintained. The recent work carried out at the
School of Mathematics proves that interventions on modern buildings are mostly insensitive to their
true significance and are often carried out in extreme urgency for mere practical reasons, if not for
political opportunities.
Modern buildings can be true architectural monuments that express great esthetic potentials and
retain notable historical weight in the history of architecture; therefore, they should be regarded as
highly representative of our recent past and maintained as such

Repository as a service (RaaS)
In his oft-quoted seminal paper ‘Institutional Repositories: Essential Infrastructure For Scholarship In The Digital Age’ Clifford Lynch (2003) described the Institutional Repository as “a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members.” This paper seeks instead to define the repository service at a more primitive level, without the specialism of being an ‘Institutional Repository’, and looks at how it can viewed as providing a service within appropriate boundaries, and what that could mean for the future development of repositories, our expectations of what repositories should be, and how they could fit into the set of services required to deliver an Institutional Repository service as describe by Lynch.<br/
