Event Description

DATE:               Tuesday April 16th

LOCATION:      Centurion Conference Event  Center, 170 Colonnade Road

THEME:            Research


PROGRAM:     Applications of Radiant Heating and Cooling Systems in Buildings

Alternatively to full air-conditioning heating and cooling may be done by water-based radiant heating and cooling systems, where pipes are embedded in the building structure (floors, ceilings, walls) or in the center of the concrete slabs in multi-story buildings. The present talk will discuss the possibilities and limitations of radiant surface heating and cooling systems. Differences in performance and application of surface systems compared to embedded systems are presented. Results from both dynamic computer simulations and field measurements are presented.


The paper shows that for well-designed buildings these types of system are capable of providing a comfortable indoor climate both in summer and in winter in different climatic zones. Various control concepts and corresponding energy performance are presented. To remove latent heat, these systems may be combined with an air system. This air system can, however, be scaled down with the benefit of improved comfort (noise, draught) compared to full air-conditioning. An added benefit can be reduced building height due to the elimination of suspended ceilings. Finally, surface heating and cooling systems use water at a temperature close to room temperature. This increases the possibility of using renewable energy sources and increasing the efficiency of boilers, heat pumps and refrigeration machines.

TECH SESSION: Low Energy Buildings – No Gimmicks, Just Good Design.

The main focus of this presentation is on the basics of design as the industry seems to have forgotten the basics. The presentation will cover the building energy end-uses to remind the audience which are the end-uses that contribute to the largest percentages of energy use, the chronic issues that plague the industry in contradiction to the guidelines from 90.1 such as too high WWR, not meeting the maximum allowed fan power limitations, the importance of recognizing thermal bridging and others. The presentation will address the discrepancy between design intent and real world performance.

Paula Kerr, P. Eng. C.EngPaula is a Mechanical Discipline Lead in the Buildings Engineering Group at Stantec in Ottawa. Paula graduated from the University of Limerick, Ireland in 2005 with a bachelor’s degree in Mechanical Engineering. One of her distinctions is a wealth of international experience in mechanical design from Canada, Ireland, and the UK. Over her 13 year career, Paula has held design, project management and senior leadership roles, working in a variety of projects in both design of new construction and complex renovations and retrofits. These projects include large-scale commercial developments, educational institutions, laboratories, recreational complexes and multi-family residential developments with various sustainable goals including the Living Building Challenge, Net Zero Energy and LEED Gold and Platinum certification. She has a personal and professional commitment to sustainable, cost-effective mechanical design with a focus of reducing energy consumption, whilst ensuring systems are also simple and easy to maintain and operate. She is a registered Professional Engineer in Alberta, BC and Ontario and a Chartered Engineer in Ireland.
Philip Richard, P.Eng., BEMP, LEED AP BD+CPhil Richard is a senior energy management consultant with the Mechanical and Electrical Group of Stantec Consulting's Ottawa office. He has 10 years of experience in sustainable design with primary focus on energy models, LEED® facilitation, energy audits, Life Cycle Cost (LCC) analysis, and mechanical design. His energy modeling experience includes; parametric studies comparing a diverse range of high performance, HVAC design solutions using energy modeling software programs including IES VE, eQuest, VisDOE, HAP, TRACE, EE Wizard, Design Builder, and EE4. In the last year Philip completed four large carbon neutral studies on behalf of BGIS for federal government buildings in the capital region including Library & Archives, John G. Diefenbaker, East Memorial Building and St. Andrews Tower. Finally, Phil is a registered LEED AP with a BD+C specialty, is also listed in the CaGBC list of approved modelers to perform 3 rd Party energy model reviews and finally, holds an ASHRAE Building Energy Modelling Professional (BEMP) designation.
Giuliano Todesco, CET, CEM, LEEP APGiuliano Todesco is a senior energy management consultant with the Mechanical and Electrical Group of Stantec Consulting's Ottawa office. He has more than 30 years’ experience in energy efficiency, energy modeling, energy auditing and energy research. He additionally has a solid knowledge of current energy codes such as the National Energy Code for Buildings and ASHRAE Standard 90.1 and is familiar with simulation tools including EE4 and eQuest. Finally, he has written articles in the ASHRAE Journal on the subject of low energy buildings and integrated building design (IBD), contributed to chapters in Low Energy Design Handbooks and has his own website on low energy buildings which can be found at and
