Nexus between running costs and building characteristics of commercial buildings: hedonic regression modelling (2020)
Journal Article
Hemba Geekiyanage, M., & Ramachandra, T. (2020). Nexus between running costs and building characteristics of commercial buildings: hedonic regression modelling. Built Environment Project and Asset Management, 10(3), 389-406. https://doi.org/10.1108/BEPAM-12-2018-0156

Purpose
Traditionally, early-stage investment decisions on buildings purely based initial capital costs and simply ignored running costs and total lifecycle cost. This was basically due to the absence of estimating models that yield running costs at...

Building organisational capacities for effective e-waste management: a conceptual framework (2019)
Presentation / Conference
Azeem, A., Mallawarachchi, H., & Hemba Geekiyanage, M. (2019, November). Building organisational capacities for effective e-waste management: a conceptual framework. Presented at 8th World Construction Symposium, Colombo, Sri Lanka

Globally, e-waste generation rises in parallel to the increased consumption of e-products. Management of this complex waste stream becomes a severe challenge, especially for developing countries. Sri Lanka also no exception to this problem due to the... Read More about Building organisational capacities for effective e-waste management: a conceptual framework.

Estimating the running costs of commercial buildings: artificial neural network modeling (2019)
Presentation / Conference
Hemba Geekiyanage, M., & Ramachandra, T. (2019, May). Estimating the running costs of commercial buildings: artificial neural network modeling. Presented at 10th International Structural Engineering and Construction Conference, ISEC 2019, Chicago, USA

Running costs of a building is a substantial share of its total life-cycle cost (LCC) and it ranges between 70-80% in commercial buildings. Despite its significant contribution to LCC, investors and construction industry practitioners tend to mostly...

Employment challanges in mega construction projects in Sri Lanka (2018)
Presentation / Conference
Nissanka, S., Ramachandra, T., & Hemba Geekiyanage, M. (2018, September). Employment challanges in mega construction projects in Sri Lanka. Presented at The 42nd Australasian Universities Building Education Association (AUBEA) 2018, Singapore

With the current economic trends, investments towards mega construction projects are happening in hefty amounts, consuming a considerable proportion, 8% of the global GDP. However, the inherent characteristics of megaprojects include a higher level o... Read More about Employment challanges in mega construction projects in Sri Lanka.

A model for early stage estimation of Operational Expenses (OPEX) in commercial buildings (2018)
Presentation / Conference
Hemba Geekiyanage, M., Ramachandra, T., & Thurairajah, N. (2018, September). A model for early stage estimation of Operational Expenses (OPEX) in commercial buildings. Presented at 34th Annual ARCOM Conference, Belfast, UK

Usually, Operational Expenses (OPEX) consume a substantial share (70-80%) of Life
Cycle Cost (LCC) of commercial buildings. Despite its contribution to the LCC
structure, often OPEX is given less focus in investment decision making and investors
t... Read More about A model for early stage estimation of Operational Expenses (OPEX) in commercial buildings.

A morphology-based model for forecasting cooling energy demand of condominium buildings in Sri Lanka (2017)
Presentation / Conference
Hemba Geekiyanage, M., Ramachandra, T., & Rotimi, J. (2017, September). A morphology-based model for forecasting cooling energy demand of condominium buildings in Sri Lanka. Presented at Association of Researchers in Construction Management, ARCOM - 33rd Annual Conference 2017, Proceeding, Cambridge, UK

Building morphology has significant influence on operational energy demand of buildings. Energy consumption for space cooling accounts for more than 75% of electricity use in typical condominium buildings. With increase in the number of condominiums...
