Level 4) - Lisnahull Terrace

1 Scheme on site being developed to Code

One of the top 50 places to live in Northern Ireland! (Belfast Telegraph)

Lisnahull Terrace, Dungannon

Experiences and Advice

  • Changing Building Standards
  • Fabric First
  • Financial “Payback”
  • M&E Concerns
  • Future Contractors
slide10

Changing Building Standards

2016 Zero Carbon Target?

How do we achieve this?

What standard should we adopt?

How will Building Regulations change?

slide11

Fabric First

Good!!

But…

What are the consequences?

What are we missing?

Do the occupants understand or share a vision?

slide12

Financial “Payback”

We are obsessed with “payback” and ROI when we talk about energy efficiency!

Relationship between fabric first and payback of equipment?

What if you are a developer or landlord?

Financial Incentives - ROCs and RHI

(RHI to be based on deemed energy consumption?)

slide13

M&E Concerns

  • MVHR issues
  • “Secondary Technologies”
  • Simplified systems
  • Correct Use of Renewables
  • User Friendly Controls
  • Thermal Stores
  • Rainwater Harvesting
slide14

Future Contractors

How many contractors will visit a home after it’s built?

What do they know about the home and how would they find out?

slide15

Occupant Lifestyles

SAP and PHPP etc are all based on assumed patterns of occupancy and living.

How many people are in the home?

How long are they in their home each day?

Do they have any special circumstances?

What temperature do they want they home?

A technology generation?
