The purpose of this article is to inform the reader of the various options available today in the management of power and communication systems within a library. These options are measured against several factors: the library’s program goals, its budget, and its structure. As library architects and interior designers, the design of the building must meet the user’s needs and the owner’s goals and be flexible to change as these needs and goals change. The facility’s ability to support technology and provide for adaptation to future changes is key to its success. This article describes six methods of managing and accessing power and communication in both new and renovated facilities. It describes the advantages and disadvantages of each system, and provides examples of their practical applications. The solutions to managing wiring for power and communication within the furniture systems is also discussed relative to how the connections interface with the building and the users. On reading this article, librarians and owners will have a better understanding of the options available and how their decisions regarding these options impacts the future adaptability of the facility.

Raised floors — independent floor surfaces raised above the structural floor surface to create a surface void — were developed to solve the problems presented by cable proliferation in computer rooms. From this early, specialist application the technique has now spread far beyond the computer suite to cope with the increased servicing needs of the general office area. The first issue of Facilities covered the deeper, platform or jacked floor type: this article is concerned with the provision of a shallower void — commonly by means of some sort of batten and particle board system — and with the issue of cable management in general.

The business case for facility expenditures is grounded in the knowledge that life-cycle economics is significant to the continued viability of the facility. The aim of this study is to develop an algorithm for life-cycle cost analysis (LCCA) and evaluate flooring products to inform decision makers about the long-term cost of ownership.

The protocol for executing an LCCA is defined by the National Institute of Standards and Technology, including defining the problem, identifying feasible alternatives and establishing common assumptions and parameters, as well as acquiring financial information. Data were provided by an independent third-party source.

The results of this study are twofold: assess functionally equivalent flooring alternatives to determine the best financial value and develop a replicable protocol and algorithm for LCCA. The study found that modular carpet was the best financial solution. As a tool for decision makers, this LCCA informs asset management about the long-term cost of ownership, providing a protocol for making practical, informed decisions for the lowest cost solution for functionally equivalent alternatives.

Projecting LCCA beyond 15 years may have limited value based on potential changes in the financial climate. Further research should focus on the implications of changes in the discount rate over time and testing the algorithm on other building systems.

Maintenance costs are considerable when compared to initial cost of flooring. Equipment costs have a significant impact on long-term cost of ownership. Using LCCA to inform specifications and to determine the best solution for a building system such as flooring provides an evidence-based process for building design and facility management.

Life-cycle costs have a significant impact on the financial health of an organization. Using LCCA to make informed decisions about facility design and specifications may contribute to increased financial stability and resources to benefit the organization’s long term goals.

This study contributes an algorithm instrument for buildings and building systems. The flooring tested with this protocol provides evidence to inform flooring selection based on lowest cost while considering other factors that inform appropriate selection of flooring materials.

Summarises the evolution of underfloor heating in buildings. Examines the main types of underfloor heating systems in ground floors. Discusses the pros and cons of this method of heating buildings. Shows that with the introduction of flow‐applied screeds and plastic piping, as well as improved installation and control procedures, underfloor heating is making a comeback in a growing number of new‐build schemes in the UK. However, this study indicates that it will be many years before universal confidence in the system is achieved.

The most serious barrier to achieving a “forgiving building” is the cost of its special building systems. The library is increasingly becoming a “hi tech” and “smart” building. A sophisticated facility is required to support current collections and the emerging electronic and optical technologies that will occupy (and perhaps dominate) the future library. It is far less expensive to provide the capacity to support future components at the time of initial construction than to subsequently renovate a building to provide needed capacities at a later date. The real challenge for librarians is to convince those who fund library construction that the “forgiving building” is the least expensive alternative in the long run.

The water damage in buildings because of leaking pipes and increasingly because of floods and severe weather require professional help. Methods for improved repair and remediation techniques have to be developed. The water damage in buildings because of leaking pipes and increasingly because of floods and severe weather require professional help. Methods for improved repair and remediation techniques have to be developed. The paper aims to discuss these issues.

Therefore, large scale laboratory tests with four rooms, each with three types of masonry walls (Figure 2 and Plate 1) and typical floors for intermediate storeys with insulation were performed within a climate simulator. Artificial water damage was provoked through watering the floors, and the dispersion of water in the floors and the rising damp in the walls was measured. In the follow-up to the watering of the floors, a company specialized in drying wet buildings, installed systems for under floor drying and wall drying.

The drying process of the different components and layers of the floor construction and walls was monitored by a measuring system with more than 300 sensors for moisture content, relative humidity and temperature accompanied by thermography and demonstrated so the advantages and disadvantages of the different tested drying systems. After providing an initial contamination that is typical for construction sites, the microbial load (mould infestation) within the wet components was monitored at different times by experienced biologists. So after three weeks under floor drying no mould growth could be asserted but more bacteria than expected were found.

The aim of the research was to gain more confidence in selecting appropriate drying procedures and systems in order to identify the right moment for terminating the drying process. A further intent was to acquire data for computer simulations.

The purpose of this paper is to report on a study which has been carried out on a timber floor construction above a ground‐supported concrete slab, which was used in small detached houses built in Sweden during the period 1960‐1990. This method of building has turned out to be a risky construction nowadays, but there are 800,000 houses built this way in Sweden.

By using the patented Air Gap Method inside building constructions, harmful water can be dried out. The method ventilates air gaps inside walls and floors with an air flow driven by thermal buoyancy caused by a heating cable in the vertical air gaps. The drying out process has been studied both by measuring the moisture level in the slab and also by measuring the humidity transport and comparing this with air flow measurements.

The paper shows that the Air Gap Method manages to dry out water from both the slab and the overlaying wooden construction. The study shows also that the relative humidity (RH) levels in the air space below the floor are reduced in a significant way, thus minimizing mould growth. It is also shown that a thin layer of concrete upon floor beams prevents mould to grow even in a humid situation.

The research reported in this paper is only concerned with timber‐framed small detached houses. Similar studies of apartment buildings are ongoing.

The Air Gap Method can thus be useful in the context of renovating a water damaged house of this type built during this 30‐year period. The method provides a possibility of drying out such damage without a separate drying period. The inhabitants could therefore be able to use a renovated water‐damaged kitchen six/eight weeks earlier compared to ordinary building methods.

The paper is useful because it provides better understanding of the mechanism of RH inside a building construction and how this parameter could be lowered. The paper is also useful in the context of renovating water‐damaged small detached houses built by the risky method of construction used in the last decades of the twentieth century.
