The High Rise building is central to any modern cityscape, attracting the attention of all who view a skyline. In just over one century buildings have grown vertically from 20 stories to over 100 stories and are now have office, hotel and residential uses. The following table shows the World's most active cities in terms of building activity on completed high rise buildings. #

Thus Toronto is tenth on the list with 1,763 completed high rise buildings.

Changing Influence on Design The design of each high rise reflected a balance between high capital costs of construction and forecast (generally) low costs of energy consumption that were applied during their design and construction. Many issues arise from changes to that paradigm. First, the use of high rise buildings is changing. On the tallest 100 buildings lists from 1930 to 2000 the percentage of office towers was never below 86%. By 2010 it will be down to just 46%.` CTBUH Journal, Issue 2, 2008. pp.40 - 41
Secondly, the cost of energy has demonstrated significant transitions in recent times. Thirdly, Governments are considering active measures to control carbon emissions that will motivate or require reduced energy consumption in existing buildings. The challenge, then, is to address the needs of existing high rise building owners to reduce the costs of energy consumption in their buildings at least cost.
Audience The array of potentially interested parties is wide. They include (in alphabetical order) 1. Architects 2. Builders 3. Bankers & Financiers 4. Developers 5. Engineers 6. Owners 7. Policy Makers in Government 8. Regulators 9. Tenants Each user group has a particular interest in the challenge of refitting an existing building to reduce energy consumption while maintaining or increasing its value in use. User groups may be broadly separated into two potential target markets: Public Sector (GOMUSH or Govt, Municipalities, Universities & Colleges, School Boards and Hospitals) and the Private Sector (Offices and Residential). Each sector differs in the type and range of buildings they own/operate and their methods of decision making.
Issues The interests of one group may be in conflict with another. The tenants will want to reduce their energy costs but will not want to suffer inconvenience during a remodelling process. The owners will not want to invest in additional capital expenditure with ne Ray Brooks

Second Draft economic return. The policy makers will want to balance tax benefits with taxes to motivate beneficial changes in behaviour. There is an argument that there should be an initial focus meeting with policy makers to clarify their wants and needs.
Proposal That an event be organized to allow interested parties from each group to express their views and hear expert opinion on the costs and consequences of green refits for high rise buildings. However they appear to be united in their need for retrofits of existing buildings that will reduce energy consumption, and thus the running costs, of their buildings. Their building users or tenants will also require the minimum of disruption during any retrofit. On the supply side there are a range of companies that offer a potential solution. They broadly include 1. 2. 3. 4. 5.
Solar and Photovoltaic walls. Smart power systems management. Geo Thermal and Lake heating and cooling. Solar cells and Wind turbine generation systems. Innovative power generation and storage systems (including fuel cell, battery/capacitor hybrids). 6. Conservation through more efficient power usage in computer, lighting and other electricity powered systems. To accommodate all of the interests of all of these groups I propose a mix of Conference sessions and plenary sessions over one day. The speakers are suggestions to stimulate discussion. The Conference may take less than a day and can be held at MaRS, seating 400, or at a University Hall if more space is required. This is a draft proposal for discussion purposes. It is being developed by an advisory committee to meet the needs of the audience members.
