The article is dedicated to the actual problem of regional housing development. The authors propose to use the existing Russian production facilities of large panel construction, which must be modernized on the basis of modern technologies, as a promising reserve for increasing the volume of housing construction. Currently, EU countries pay considerable attention to cluster strategies as an effective tool for the innovative development of regions and enterprises. Recently, there has been a significant amount of interest to this problem in Russia. It identified distinctive parameters of the formation and implementation of regional cluster construction policies, industrial housing on an innovative basis in comparison with traditional industrial and construction policies. The need for an integrated approach to innovative solutions in the field of technology and construction management has been proved. The need for improving the spatial organization of construction by creating industrial housing construction clusters on the territory of large industrial regions has been justified, which, according to the authors point of view, will help to find a fast solution of the housing problem in St. Petersburg and in Russia as a whole.

“…Another advantage of SIPs over the traditional framing is that SIPs are assembled on-site as a whole panel and delivered on-site ready for installation. As such, the reduced number of joints improves airtightness [19]. Reportedly, SIPs have higher insulation values compared to their conventional counterparts.…”

Understanding Construction Stakeholders’ Experience and Attitudes toward Use of the Structurally Insulated Panels (SIPs) in New Zealand

et al. 2019

New Zealand faces a housing shortage with construction struggling to meet demand. Structurally insulated panels (SIPs) have been demonstrated internationally as a method of construction which could reduce construction time frames, improve the standard insulation in housing, as well as reduce the amount of waste generated on construction sites. However, anecdotal evidence shows that the SIPs’ adoption is lacking, which is, perhaps, attributed to its industry-wide acceptance level. Thus, in this study, the construction stakeholders, such as architects/designers, builders, territorial authorities and homeowners were targeted to shed light on current status of SIPs use, benefits offered and any barriers inhibiting its industry-wide implementation. This was done through a survey, which was designed to understand the construction stakeholders’ experience levels regarding SIPs use in New Zealand as well as their opinions about any problems associated with the SIPs adoption. Although the stakeholders were happy with the thermal performance offered by SIPs, the results indicate that lack of familiarity and understanding are one of the main barriers to the widespread use of SIPs in New Zealand. Moreover, proper training and clear design information are reported to be crucial to make the building and consenting processes efficient, which will ultimately improve the cost-effectiveness. Despite the barriers (to SIPs adoption) documented by stakeholders, the common belief is that SIPs offer wide-range of benefits to improve performance of the built environment; hence, the stakeholders expressed their willingness to design/build/recommend SIP homes. It is hoped that the findings of this study will guide the industry practitioners in investing their efforts in wider adoption of SIPs in New Zealand.

“…The building envelope is locally sensitive to exfiltration airflow, as moisture convection could cause a remarkable increase in the moisture accumulation rate on the inner surface of the sheathing (Kalamees & Kurnitski, 2010). Kayello et al (2017) showed that frost accumulation and condensation can happen very easily due to air leakage and pose a significant risk to the integrity of the envelope. In building envelope, the CLT is often used as air barrier layer.…”

In building envelope, the cross laminated timber (CLT) is often used as air barrier layer. The objective of this study was to evaluate the impact of production technologies such as edge bonding, different initial moisture content (MC) of lamination, and number of lamination layers (3 and 5) on the air-permeability properties of cross laminated timber. Air leakage and crack growth in CLT panels were measured after the panels were conditioned in environments with different relative humidity (RH) in progressive steps from humid to dry environments (RH 70%→ RH 50%→ RH 30%→ RH 10%). The test results showed that the most effective technologies for avoiding large crack growth and air leakages through panels were to use 5 layers of laminations with bonded edges. Overall, it can be recommended that for the production of CLT panels it is advisable to use primarily a larger number of layers, at least 5, for smaller growth of cracks on panel surfaces and thereby avoid air leakages during the time of use. The use of bonded edge technology helps to ensure the avoidance of possible air leakage threats, but in the long-term, this beneficial effect might decrease as bond layers may rupture or cracks may form in the middle of laminations.
