As Canada's first C-2000 office building, Green on the Grand was designed to be energy-efficient and environmentally responsible. Computer simulations and detailed calculations compared the energy consumption of Green on the Grand with that of a similar office building built to contemporary energyefficiency standards (ASH RAE 90.1 ). 

The paper outlines the design concept of the condensing boiler and its application in domestic heating systems and discusses the energy savings, investment opportunities and other benefits that can be realised. It also examines the potential market for condensing boilers and some initiatives that are aimed at promoting them in regard to both the end user and the heating designer and installer.

Exploiting lhe energy saving potenllal of thermal mass does not require heavier buildings. More important Is how that
mass is exposed and utilised.

The belief that the addition of mass to a building will reduce its energy requirement is now widespread. Fiona Cousins and Bob long investigate how this principle, often observed in the coolness of cathedrals, castles and caves during summer, can be applied to modern buildings

A knowledge of Russian building thermal-energy codes in effect in the post-World War II era is necessary for estimating the performance of the existing building stock, quantifying the impact of energy conservation retrofits, and estimating the benefits of more stringent codes. This paper begins with a thorough review of the prescriptive-based national codes that applied to heated buildings constructed in the Soviet era. The codes defined all envelope thermal performance requirements for space heating.
