Sustainability is so important that both the MDGs and SDGs as United Nations development initiatives have listed it as a vital component. Non-sustainable practices lead to depletion and destruction of the environment with consequences that are still being understood. This could even get worst if professionals in the Building industry do not key into the sustainability initiative. Architects, as professionals in the built environment, take the most important decisions as far as the design and construction of buildings are concerned. Their awareness and knowledge of sustainable building materials is very important in solving this emerging problem. This study is aimed at evaluating the level of awareness of Architects on sustainable Building Materials. This is measured by looking at the knowledge, specification and application of sustainable building materials. The study was qualitative hence; data was obtained through a six-item structured schedule of interview. A total of 18 registered Architects were purposively selected for the study. The results obtained showed that as we get close to two decades since international attention has been drawn to sustainability, there is still a low level of awareness and knowledge of sustainable building materials among Architects. The study also revealed that Architects sometimes do not like pushing boundaries out of their comfort zones as far as specification writing is involved. In conclusion, the study recommended the updating of building bye-laws of the state, intending to make the Architects update their knowledge of sustainable Building Materials as a result of the more regular application in their designs.

Environmental noise constitutes a major contributor to environmental pollution, with its unintended consequences posing a serious challenge to public health in the built environment. This study assessed the perception and the implications of urban environmental noise on urban residents' wellbeing. Data was collected using a sound pressure level meter and a self-developed questionnaire. Findings from eight hundred and eighty (880) responses obtained through random sampling were analysed and benchmarked against national (50 dBA) and international (55 dBA) standards by the WHO. The results showed that noise from places of worship and traffic noise were rated high, with about 75 percent of the respondents indicating that environmental noise negatively impacts their wellbeing. The study suggested the need for improved environmental quality in the built environment. It advocated for synergistic interventions from architects, other built environment professionals, and environmental protection agencies to tackle urban environmental pollution in residential environments. The contribution of this research lies in the necessity for further investigation, since it has important ramifications for architects, urban planners, and urban managers.

Rural to urban migration has been a disturbing factor in Nigeria. The urban cities have become over populated resulting into poor provision of comfortable and healthy accommodation for the citizenry. The menace has further metamorphosed into complex units of socio-economic and cultural degradation, increasing youth unemployment, poor housing delivery, and depletion of the ozone layers due to carbon dioxide emission from small electric generators called "I pass my neighbor". The situation is no longer convenient to be curtailed because of the limitations of the existing institution to provide mechanism to curtail the growing challenges. This indicates a factor of undermining urban poor of affordable and decent housing, which makes them "homeless. The research aims at conveying into luminance the drivers of low energy materials that could be employed through sustainable measures to deliver public housing in Nigeria. The objective brings forth considerations for application of low energy materials that can be integrated at the design stage to reduce the energy used in achieving comfort and limit the overall energy consumption of residential buildings in Nigeria. The purpose is to make public housing affordable and sustainable in Nigeria. The study employed the use of qualitative data analysis from relevant literatures. The results obtained indicate the high energy delivery in Nigeria's public housing reflects the overgrowing poverty level in the country. The population living in poverty has remarkably grown from 1980-2010. This factor has made it difficult for the majority poor populace to own a house due to the high cost involved in obtaining a high energy material for building construction. The study recommends a drift to low energy materials, which involves lesser energy of production and are locally found in the country, and tends to provide affordable housing to the poor living in urban centers. Hempcrete, cob, raw earth, sheep wool, bamboo, rice hull, wattle and daub, rammed earth, the mud, adobe, fire brick, are available traditional building materials with low energy richly found in Nigeria, government and private developers should adopt them in construction of dwellings to curtail the limited provided accommodation for the increasing population in urban centers and to provide decent, affordable, and sustainable accommodation to Nigerians.

Tourism involves visits to destinations of choice for recreation, medical, or business purposes. This industry, which is considered as one with a fast growth rate, could generate a huge amount of revenue and employment if it is properly planned and managed. Future development plans for tourism in line with architectural heritage would bring more insights and create interest for present as well as future generations. Nigeria is blessed with treasures of architecture that can people to travel to the cities for tourism. As such, the need arises for architecture to step in and respond to the diverse needs of tourists, be them cultural, medical, or landscape needs. Hence, this research explores the role of architecture in promoting tourism that furthers economic development through the built environment in Nigeria. It is based on a qualitative research method. Data was primarily obtained through questionnaires and semi-structured interviews. Relevant literature was also studied in a bid to elucidate useful information on the subject matter. The findings showed the indelible mark of architecture on tourism growth and development. Although, the availability of tourism infrastructure and the attractiveness of these attractions remain inadequate and below average. The current research, therefore, concludes that modern tourism is closely linked to architectural development which could turn tourism in Nigeria into a key driver of socioeconomic development and growth, if considered.
